2012 Volvo V60 sports wagon 05.07.2010

In an attempt to capture a larger number of sales in the competitve European wagon category, the new Volvo V60 has been launched as the sporty five-door version of the all-new S60.  The car is being offered with eight different engines in an attempt to lure at least 50,000 new customers annually.

The V60 is available with four inline-four petrol engines, including two 1.6-liter units that produce up to 240 Nm of torque and either 150 or 180 horsepower (112 or 134 kW), and two 2.0-liter models that produce either 203 hp (151 kW) and 300 Nm or 240 hp (179 kW) and 320 Nm.

Its range-leading inline-six is a 3.0-liter unit that kicks out 304 hp (227 kW) and up to 440 Nm.  This powerful engine gets the car from 0-100 km/h in 6.6 seconds, with an electronically-limited top speed of 250 km/h.

Diesel offerings include a 115-hp (86 kW), 270-Nm 1.6-liter inline-four, and two inline-five workhorses.  The first is a 2.0-liter model that kicks out 163 hp (122 kW) and up to 400 Nm, while the top diesel model churns out 205 horsepower (153 kW) and up to 420 Nm.

“Many of the customers who had an advance look at the new V60 during the development process feel that its attitude is at least as sporty as that of the all-new S60,” said Volvo Design Director Peter Horbury.

To make the car look sportier, it has been given a coupe-inspired roof, sculpted styling at the front, and a bulging “shoulder” to keep with Volvo’s design language.  The car will be sold on a new dynamic chassis in Europe, though some markets will get a choice between a touring chassis and the European standard with its stiffer dampers.

Collision avoidance, pedestrian detection, all-wheel drive, tight steering, stability control, traction control in the corners, and an advanced brake system are all included for the driver’s benefit.  Fold-flat seating is not only used at the back, but also with the front passenger seat, which means loading long objects through the 1,095mm-wide tailgate.  Total load capacity is 430 liters.

Look for pricing of the new Volvo V60 to be announced soon.  Plenty more details in the press release below.

New Volvo V60 sports wagon – as sporty as the all-new S60

The Volvo V60 makes its entry onto the car market with its sights firmly set on giving the all-new S60 sedan model a tough match over the title of “The Most Dynamic Volvo Model Ever”.

“Many of the customers who had an advance look at the new V60 during the development process feel that its attitude is at least as sporty as that of the all-new S60,” says Volvo Cars Design Director Peter Horbury.

No less than 90 percent of the annual V60 production of 50,000 cars will find European buyers.

“The typical sports wagon customer is an S60 buyer who would like some extra space and flexibility, but without the slightest compromise on sporty design and exciting driving properties,” says Volvo Cars President and CEO Stephen Odell, and adds:

“The competition is razor-sharp and the customers in this segment know exactly what they want. That is why we have further boosted the interior’s sense of exclusive quality and packed the car with safety- and comfort-related technical innovations. The result is a truly unique sports wagon, in total harmony with its sporty attitude.”

Coupe rather than estate car

The pronounced wedge shape and the slim coupe-like roof line of the new V60 are accompanied by the shoulder profile along the car’s sides, creating a gentle yet powerful double wave from the headlamps at the front to the tail lamps at the rear.

“From the design viewpoint the focus was on making the car as close to a coupe as possible, while retaining that handy extra space at the rear. Our sports wagon does not aim to compete with the traditional estate car. For the customer who wants a lot of load space, there is our V70 or XC70,” says Örjan Sterner, head of exterior design for the new Volvo V60.

He adds:

“The dip in the middle of the double wave visually pushes the car down. This enhances the stance and makes the car look sleeker and lower. The sculpted bonnet and the short overhangs front and rear also emphasise the sports car feel.”

Uncompromising chassis approach

Volvo Cars’ chassis experts have chiselled out the driving experience in the new Volvo V60 with the same passion and uncompromising approach that characterised the development of the all-new S60 sedan.

The result is an authentic sports wagon with driving properties that do the sporty lines full justice.

“We’ve pushed the envelope to limits we’ve never previously approached. You simply have to drive this car to appreciate how we’ve driven chassis development to its pinnacle. Take the car out on a narrow, winding country road where every bend brings a new challenge and the new V60 will demonstrate its agility with sparkling enthusiasm,” says Stefan Sällqvist, who headed the development of the chassis in the new V60.

Volvo’s new sports wagon is available with a choice of two chassis. On the European market the newly developed dynamic chassis is standard, while some other markets will have the touring chassis as standard with the dynamic variant available as an option.

The difference between the two chassis alternatives is to be found in the dampers and the front and rear subframes. Here the touring variant has a somewhat softer setting to give a smooth ride on poorer road surfaces.

Every single detail refined

“The spotlight was on giving the concept of comfort a whole new dimension. The dynamic chassis has an alert, quick-responding character that puts the focus on the driving experience, yet without diluting ride comfort,” explains Stefan Sällqvist.

In addition to the two standard chassis, all variants of the V60 can be specified with the optional FOUR-C (Continuously Controlled Chassis Concept) active chassis, which has been modified and refined for better control and comfort compared with previous Volvos.

The software in the AWD (All Wheel Drive) system has been modified to allow the four-wheel drive variants (AWD is standard in the T6 and optional with D5 with automatic gearbox) of the new V60 to exploit the sporty new chassis to the limit.

During the development process, the chassis team worked on the new Volvo V60 in parallel with the all-new Volvo S60. The result is a solution that features changes and refinements to virtually every single detail that influences a car’s driving properties. This includes improved steering, stiffer springs and bushes as well as more damping than in any previous Volvo.

The first sports wagon with Advanced Stability Control

The dynamic new chassis is backed up by a range of electronic systems that sharpen the sporty driving experience still further.

Like the all-new S60, the new V60 is fitted with Advanced Stability Control. With a new roll angle sensor, it is possible to identify any skidding tendency at a very early stage. This means that the anti-skid system can step in earlier and with greater precision. Advanced Stability Control is a great asset in dynamic driving involving considerable lateral forces, which improves handling and rapid avoiding manoeuvres.

New Corner Traction Control for smoother cornering

Corner Traction Control is a new feature that uses torque vectoring so the car corners even more smoothly. This technology is a further refinement of the Dynamic Stability and Traction Control (DSTC) system.

When cornering, the car’s inner driven wheel is braked, causing more power to be transmitted to the outer driven wheel. This allows the driver to corner more tightly while reducing any tendency to understeer.

A highly advanced braking system is an important part of the dynamic driving properties of the new V60. Volvo’s new sports wagon is equipped with a number of features that interact to provide the shortest possible stopping distance in all scenarios.

Exclusive quality – with extra functionality

The interior of the V60 sports wagon is a clear example of how Volvo Cars’ designers have added excitement, contrast and a playful element to the Scandinavian design tradition’s rational simplicity and functionality.

“The interior has a decidedly extrovert attitude, but without losing any of its practical Scandinavian roots. The new V60 brings us up to a whole new level when it comes to the integral experience of colour, form, material and technology,” says Volvo Cars’ Design Director Peter Horbury.

The interior is thus lavish in terms of its driver-oriented details, but it is still a five-seater car offering comfortable space for all its occupants. Scandinavian design’s rationality, simplicity, clarity and functionality are all prominent in the new V60:

The 40/20/40-split rear seat and the fold-flat front passenger seat make it possible to combine passengers and load in a remarkably flexible way. Each backrest in the three-piece rear seat is folded with exceptional ease to create an entirely flat load floor. The rear seat headrests can be folded electrically.

The load area has been designed for maximum utilisation of each available millimetre. The 1095 millimetre wide tailgate in combination with extra space behind the wheel housings and under the load floor is an example of the systematic approach adopted to ensure generous load capacity. The load area has a capacity of 430 litres.

The rear seat can be specified with integrated child booster cushions in the two outer seats.

The most high-tech Volvo ever – with Pedestrian Detection

The sporty interior of the new V60 is also the most advanced high-tech environment ever available to a Volvo driver.

“The interior of the new V60 is all about innovative design in two areas: form and technology. The design is characterised by sporty freshness down to the smallest detail. The technological aspect includes all those smart solutions that contribute to a driving experience unlike that of any other Volvo – from collision avoidance safety and comfort systems to infotainment and audio excellence of absolute world class,” says Tomas Ahlborg, Project Director for the new V60.

Pedestrian Detection with full auto brake can detect if a pedestrian steps out into the road in front of the car. If the driver does not respond in time, the car can automatically activate the brakes.

“Volvo has always led the way when it comes to protecting the occupants in our cars. In recent years we have adopted groundbreaking initiatives that help the driver avoid collisions with other vehicles. Now we are taking a giant stride forward with technology that can contribute to increased safety for unprotected road users as well,” says Thomas Broberg, Senior Safety Advisor at Volvo Cars.

Can avoid collisions at speeds below 35 km/h

In an emergency situation the driver first receives an audible warning combined with a flashing light in the windscreen’s head-up display. In order to prompt an immediate, intuitive reaction this warning resembles a brake light. At the same time, the car’s brakes are pre-charged. If the driver does not react to the warning and an accident is imminent, full braking power is automatically applied.

Pedestrian Detection with full auto brake can avoid a collision with a pedestrian at speeds up to 35 km/h if the driver does not react in time. At higher speeds, the focus is on reducing the car’s speed as much as possible prior to impact. Speed can be reduced by up to 25 km/h.

Statistics reveal that the car’s speed has considerable importance for the outcome of the accident. A lower speed of impact means that the risk of serious injury is significantly reduced.

City Safety standard

The new Volvo V60 also features City Safety as standard.

With City Safety, the car automatically brakes if the driver fails to react in time when the vehicle in front slows down or stops – or if he or she is driving too fast towards a stationary object. The system can lessen or even entirely avoid low-speed rear-end impacts at speeds up to 30 km/h.

More powerful T6 version

During its first year of production, the new Volvo V60 will be available with a variety of diesel and petrol engines spanning the range from an economical 115 horsepower DRIVe version to an eager high-performance turbocharged version producing 304 horsepower. The focused drive to cut CO2 emissions has lowered fuel consumption throughout the engine range.

The T6 petrol engine has a displacement of 3.0 litres and has been improved still further, primarily thanks to lower internal friction. It now pumps out 304 bhp and no less than 440 Nm of torque. Acceleration from 0-100 km/h takes 6.6 seconds and top speed is limited to 250 km/h.

At the same time, Volvo Cars’ engine specialists have succeeded in cutting fuel consumption by about 10 percent to 10.2 l/100 km (EU Combined).

The engine’s power is delivered to the wheels via Volvo’s second-generation six-speed automatic Geartronic transmission. New valves and lower friction mean faster gearchanges than before. AWD (All Wheel Drive) is standard on the T6.

New direct-injected two-litre engine

The new four-cylinder 2.0T GTDi (Gasoline Turbocharged Direct Injection) engine has a displacement of two litres and produces a generous 203 bhp, with 300 Nm of torque available from 1750 rpm. Acceleration from 0-100 km/h takes 7.9 seconds with a manual gearbox and 8.4 seconds with automatic transmission. Top speed is limited to 230 km/h with the manual gearbox and 230 km/h with the automatic.

New in-house-developed turbocharged technology, direct injection and twin variable camshafts produce a unique combination of low fuel consumption, low emissions and a high and broad performance range, all packaged in a very compact format.

Later during the first year of production, the new V60 will also become available in a 2.0 GTDi variant producing 240 bhp and 320 Nm of torque.

Two new 1.6-litre GTDi engines

In addition there is a new 1.6-litre GTDi engine which is available in two versions: 1.6 GTDi (T3) with 150 horsepower and T4 with 180 horsepower.

The 180 bhp engine offers maximum torque of 240 Nm from just 1500 rpm all the way up to 5000 rpm. During short-term overboost, it provides an impressive 270 Nm of torque. This gives excellent lugging ability throughout the speed range. The torque curve is relatively gentle, resulting in a particularly comfortable driving experience.

The 150 horsepower engine offers 240 Nm of torque.

The 2.0T, T5 and T4 are available in combination with Volvo’s automatic six-speed Powershift transmission or a six-speed manual gearbox, while the T3 comes with a manual gearbox.

Two five-cylinder turbodiesels

The engine range also includes two five-cylinder turbodiesels.

The D5 high-performance engine with twin turbos produces 205 horsepower and 420 Nm of torque. Acceleration from 0-100 km/h takes 7.9 seconds (manual and automatic). Top speed is 230 km/h (limited) with the manual gearbox and 230 km/h with the automatic.

In the most recent D5 version, which was introduced in spring 2009, performance and driveability requirements have been met by fitting two turbochargers of different sizes, one taking over from the other and providing added power across a broader rev range.

The complementary properties of the two turbos are utilised optimally for a combination of high performance and low fuel consumption of 5.4 l/100 km (EU Combined) putting this engine in the running for best in class.

In addition there is the newly developed two-litre D3 producing 163 bhp and 400 Nm of torque. Acceleration from 0-100 km/h takes 9.4 seconds (manual and automatic). Top speed is 220 km/h (manual) and 215 km/h (automatic).

The new five-cylinder 2.0D is in principle the same engine as the present 2.4D, but cylinder capacity has been reduced with a shorter stroke to optimise fuel consumption.

Both turbodiesels are available with a six-speed automatic transmission or six-speed manual gearbox.

The D5 with automatic can also be specified with all-wheel drive.

DRIVe diesel

During the course of the first year of production, a DRIVe version of the new V60 will also be introduced, featuring a 1.6-litre diesel engine. The engine produces 115 bhp and 270 Nm of torque, and will only be available with a six-speed manual gearbox.

Engine range

Entirely new Infotainment system

The new V60 also gets an all-new Infotainment system where information is presented on a five-inch or seven-inch colour screen in the instrument panel. The screen has a high position to make it easy for the driver to keep his or her eyes on the road.

The audio experience in the new V60 has been further enhanced compared with previous models.

“Our most advanced system, Premium Sound, has a class-D digital 5×130W amplifier with circuits from Sweden’s Anaview, Dolby Digital in combination with Dolby Pro Logic II Surround, the award-winning MultEQ from Audyssey Laboratories and 12 loudspeakers. All this creates an audio experience of absolute world class,” says Tomas Ahlborg.

The Volvo V60 is one of the first car models in the world to use the Audyssey Laboratories MultEQ technology. MultEQ eliminates the distortion caused by the car cabin’s acoustics, providing crisp, clear sound with improved soundstage for everyone in the car.

In addition to the top-of-the line Premium Sound, which comes with a 7-inch screen, there are another three audio systems.

European target group

The initial annual target for the new Volvo V60 is 50,000 cars. Of these, no less than 90 percent will go to European buyers. The five largest markets are Sweden, the United Kingdom, the Netherlands, Italy and Germany.

The new V60 is built at the Volvo Cars production plant in Torslanda, Sweden. The first cars will be delivered to customers in autumn 2010.

“The figure ‘60′ in our model range nowadays indicates our sportiest models. The XC60 was the first step. We took the next step with the all-new S60 sedan – and now we’re launching the V60 sports wagon,” says Stephen Odell.

Volvo Electric Vehicle design sketch illustration – 800 – 25.01.2010

A futuristic-looking sketch depicting what Volvo described as “a future Volvo electric car?” surfaced during a presentation at an event by EnerDel, lithium-ion battery suppliers for the electric Volvo C30. The sketch was signed by one Stefan Jansson and is quite bold, with a menacing front end and oversized wheels.

Dan Johnston, a spokesman for Volvo played down suggestions of anything resembling the final electric car design, saying the sketch is just that, a sketch.

“It’s just one of the designer guys in Sweden playing around,” Johnston told Insideline. “We won’t have an electric vehicle that looks like an electric vehicle. It won’t be like a Prius. You’ll see the continuation of [our] design language on the C30.”

However, seeing as though the Swedes were actually pressured by an excited public into building the C30 from that radical Volvo Safety Concept Car of 2000, there is no saying this won’t happen again with this sketch.

Volvo could be preparing a C30R

Volvo C30R

After learn that Volvo will manufacture a version of the Volvo C30 family, we can only know when to arrive by the model of high performance. The announcement of the new Focus RS has reason to talk to kids Swedespeed, who claimed to have heard rumors about a possible Volvo C30R. At the moment is little more than pure speculation, but to materialize, the Volvo C30 boldest should equip a 300 hp engine with power and traction to all four wheels.

One reason for hope is that Ford Focus RS does not sell in the United States, which incidentally is the largest market for Volvo. This shortage could force the company to fill the hole with a new product, but belongs to another brand. Does the Volvo C30R ? As far as we are concerned, is already taking. Volvo C30 R …

Rumor: Volvo already has a C30 R. .. but does not have its launch

Volvo C30 R

Volvo already gave him a good brochazo testosterone to Volvo C30 R with the presentation of the R-Design package, but unfortunately the hormone treatment remained in the aesthetic. Now comes the news that the Swedish firm has developed a prototype that, with the five-cylinder engine of the Focus RS and a new turbocharger, is capable of delivering the disproportionate figure of 350 hp. And not only that: besides, this seemingly model tests would be equipped with traction at all four wheels, ensuring optimal control at all times. The problem is that according AutoTelegraaf, there are no plans to bring production Volvo C30 R .

Considering that the range Volvo C30 R was canceled some time ago, this unit for internal use may be a pitch aimed at executives to reconsider its decision. Nothing easy, taking into account the political circumstances (emissions) and economic (oil) with which currently have to deal high-performance models Volvo C30 R .

Volov S60 Concept at 2009 Detroit Auto Show

Swedish automaker follows parent company Ford and pulls out of the Tokyo motor show

Volvo is the latest automaker to pull out of the Tokyo motor show.

The Swedish automaker announced last week that it would not take part in the motor show. Parent company Ford, along with fellow Detroit automakers GM and Chrysler, also pulled out of the show last week.

The association which runs the Tokyo motor show, the Japan Automobile Manufacturers Association (JAMA), had considered canceling the show due to a lack of participation but last week announced it was going forward and holding it. Some members had believed that the current global automotive crisis warranted skipping the show for this year. But the major Japanese automakers were committed to the show and will now be participating.

One of those is Mazda, which has said it will be at the show. The automaker is also closely allied with Ford, which owns 13 percent of Mazda. Ford once held a 33 percent share of the Japanese automaker but sold off most of its stock last year to raise cash. Ford sold 20 percent of Mazda for 540 million US dollars.

The Tokyo Motor Show takes place every two years. Press days for this year’s show will be the 21st and 22nd of October. The public show takes place from October 23rd to November 8th of this year.

Volvo D5 sequential twin-turbo diesel engine – Euro 5

New D5 twin-turbo diesel engine features 205 hp and 420 Nm of torque

Volvo has released full details of its new 2.4 liter D5 diesel engine which will go under the bonnet of the brand’s flagship model, the S80.

The Swedish automaker claims that this engine is completely new, sharing only the D5 badge and cylinder-block with the previous power plant. The new D5 is now Euro 5 compliant and offers more fuel efficiency than the earlier D5.

Twin turbo-chargers and piezoelectric fuel injectors create a torque-suffused pull across the rev band with the new D5 churning out 205 hp (at 4000 rpms) and 420 Nm of torque (between 2900 and 5000 rpms). The D5 is made out of aluminum, which dispenses heat more evenly, and temperature control is improved with a new transverse-cooling technology.

The efficiency numbers are impressive too, with CO2 emissions at 164g/km and fuel-economy of 45.6 mpg (UK), or 6.2 liters/100km, for the full-sized S80 sedan.

The D5 took 3 years to develop and it is meant to keep Volvo competitive in the premium brand segment, where automakers are continuously improving fuel-efficiency through new technologies.

VOLVO’S NEW EURO 5 D5 DIESEL ENGINE OFFERS INCREASED PERFORMANCE AND LOWER FUEL CONSUMPTION

Volvo Cars is introducing a new 2.4-litre 5-cylinder diesel engine in the Volvo S80. Sharing only the D5 badge and the five-cylinder configuration with the previous generation, the new engine is now Euro 5 compliant and is significantly more efficient than its predecessor. The new D5 engine will be available in the UK from mid-2009 and pricing and specifications will be announced nearer the time.

With innovative engineering solutions such as sequential twin turbochargers, ceramic glow-plugs and piezoelectric fuel injectors, Volvo’s engineers have succeeded in cutting fuel consumption to some of the lowest levels for a car of this size – 45.6mpg, while CO2 emissions are only 164g/km. These low levels of fuel consumption, in combination with improved power output of 205hp and 420Nm of torque, mean the Volvo S80 with D5 engine is bidding for the best in class title.

“Our brief was to develop a modern performance diesel engine that meets the Euro 5 standard,” says Derek Crabb, Vice President, Powertrain Engineering. “The previous engine has undergone constant development but has now reached the end of its potential. We therefore decided to start with a clean sheet of paper and harness the advanced technology which we have access to today. The result is even better than we dared hope. What is more, this engine has been developed entirely in-house at Volvo.”

Performance and driving comfort of top class
Volvo’s new D5 engine has a displacement of 2.4 litres, offering power and response as soon as the accelerator is depressed. The performance and driveability enhancements have been made with the use of twin different-sized turbochargers that operate in sequence to provide added power within a broader rev range. The result is an immediate response and rapid acceleration at all speeds, with smooth power delivery between the two turbo ranges.

At lower rev ranges, the smaller turbocharger ensures rapid acceleration without any perceptible lag, while at higher ranges, the larger turbocharger delivers the high levels of power torque not available with a single unit. This power means there are always ample resources for quick overtaking, particularly between 50 and 75 mph.

This twin-turbo technology has also made it possible to introduce higher levels of exhaust gas recirculation (EGR) across a wider rev range than before. This harnesses the two turbochargers’ different properties optimally to deliver high performance and low fuel consumption.

Advanced injection technology using piezoelectric fuel injectors provides precise distribution of the atomised fuel in the combustion chamber, resulting in efficient combustion and low emissions. At the same time, this technology and the efficient combustion deliver a refined engine note, bearing a closer resemblance to the noise of a six-cylinder petrol engine. The engine offers excellent results in terms of noise comfort and noise perception, technically known as NVH or Noise, Vibration and Harshness.

The injection system with its piezoelectric fuel injectors and high-efficiency fuel pump also help cut fuel consumption through extremely rapid and precise injection sequences and high injection pressure, resulting in particularly effective combustion.

Lower fuel consumption
“When the project got under way, our goal was to bring fuel consumption down to 44.1mpg in the Volvo S80, which, after all, is a relatively large car,” recalls Derek Crabb. “As the work progressed, we saw that we could beat that target and today we are actually up to 45.6mpg. With an automatic gearbox we have been able to reduce the consumption by more than 8 percent, from 38.7 to 42.2mpg, which is a significant improvement.”
  
Low emissions and easy breathing
“The technical solutions that contribute to this low fuel consumption also help reduce the engine’s environmental footprint,” explains Derek Crabb. “Reducing emissions and particulates was one of the basic requirements when the new engine was being developed.”

In addition to twin turbochargers, piezoelectric fuel injectors and improved EGR control, the new D5 engine has been equipped with ceramic glow-plugs, an innovative solution that delivers excellent cold-starting properties thanks to a very quick warm up period. They reach a temperature of 1000 degrees Celsius in just two seconds, making the engine easy to start and thus cutting emissions. In certain driving conditions, such as at very low revs, the heat generated by the ceramic glow-plugs can also be used to increase the temperature in the cylinders, further improving combustion efficiency.

The advanced injection technology makes it possible to supply additional fuel in tiny increments after the main injection charge, a process known as post-injection, with the aim of removing any soot particulates in the exhaust gases.

In order to ensure low particulate emissions, the engine has to be able to breathe easily and efficiently. And here Volvo’s engineers have succeeded again thanks to optimised control of air delivery to the cylinders.
  
Three years from project start to delivery
The new five-cylinder diesel is the first engine from Volvo’s new project office for diesel engine development.

“The entire process from receiving the brief to installing the first engine in a car has taken less than three years,” says Derek Crabb. “The aim was to develop a diesel engine with performance and driving comfort that satisfied the high demands of customers in the S80 segment. It also had to be tailored to meet forthcoming strict environmental requirements,” he added.

The engine was developed on a modular basis in terms of both design and building method, using standardised mountings for the turbochargers and other components. This makes it easier to install in other Volvo models and gives more scope for further development to meet future demands.
  
The technology in brief

The D5 engine is made entirely out of aluminium, giving low weight and good heat dissipation properties.

Transverse cooling gives uniform cooling of the cylinder head and engine block. This promotes a controlled temperature throughout the engine and contributes to high reliability and long lifetime.

The two turbochargers are of different sizes and together deliver high boost pressure, 1.8 bar, across a particularly broad rev range. The smaller turbocharger is used primarily at lower revs. It reacts more quickly than the larger one and provides immediate response to quick throttle movements. At higher revs, the larger turbocharger takes over to provide more performance when accelerating at higher speeds. In addition to increased performance and reduced fuel consumption, the twin-turbo approach makes it possible to exploit the EGR system more efficiently.

By increasing the volume of the EGR cooler and equipping it with effective cooling fins, it has been possible to increase heat dissipation efficiency by no less than 25 percent. This in turn cools the returning exhaust gases to a far lower temperature, thus reducing emissions of nitrogen oxides (NOX) to a level that easily matches the Euro 5 requirements.

The piezoelectric fuel injectors are used in combination with an efficient high-pressure fuel pump to achieve a high injection pressure of 1800 bar. This type of injector has a nozzle with a response time twice as fast as that of a conventional injector nozzle. As a result, the amount of fuel injected can be tailored precisely to suit any operating condition which, in turn, delivers effective combustion, lower fuel consumption and reduced emissions of harmful substances. Owing to its speed, a piezoelectric injector nozzle can deliver up to seven separate injections during each operating cycle. Thanks to this speed and the high fuel delivery pressure, the injector nozzle can provide short pre-delivery injections even when engine revs exceed 3000 rpm, ensuring a refined engine note. The piezoelectric injector nozzle can also produce extremely short post-delivery injections of fuel after the main injection sequence.

The D5 engine features common-rail injection via a stainless steel fuel rail that is specially designed to withstand the high pressures. Injection pressure can be as high as 1800 bar.

The fuel pump is a high-pressure unit with two pump elements instead of three as in the previous D5 engine generation. This makes the pump spin more easily, thus reducing the load on the various components. It also reduces fuel consumption.

Ceramic glow-plugs are components that offer excellent starting properties. They are heated up almost instantaneously and reach 1000 degrees Celsius just two seconds after a cold start. Maximum operating temperature is 1300 degrees, which is about 30 percent higher than that of a conventional glow-plug. With ceramic glow-plugs, the engine can be started immediately without pre-heating, even at temperatures as low as minus 30 degrees Celsius.

Instead of using an oil dipstick the driver is alerted via the information display if the oil needs replenishing. The system even specifies how much oil is needed.

Finally, the engine mountings have been further developed and tailored to suit the high torque levels. They are supplemented with a third torque rod to stabilise the engine during firm acceleration.

Engine specification, new D5, Euro 5 (Volvo S80)

“In conclusion, Volvo’s new high-tech 5-cylinder diesel engine marks yet another step in our determination to reduce the combustion engine’s environmental impact, at the same time as we give S80 customers a truly quiet and sophisticated engine with excellent performance,” concludes Derek Crabb.
