Tough but competitive WTCC weekend for Volvo Polestar Racing in China
The FIA World Touring Car Championship (WTCC) weekend in China turned out to be tough for Thed Björk and Volvo Polestar Racing despite being on pace with the very top of the field. ”I would of course have liked to finished better. But we showed that we have the pace to challenge the top guys of WTCC and I am very proud of that,” said Björk.
The double STCC champion started the weekend by being fastest in practice, despite never having seen the track before and with a car that had not been raced with for two years. The impressive paced continued in qualifying where Björk was seventh fastest, six tenths from pole position, but was not allowed to take part in the second qualifying session as the FIA classified the car as nationally homologated.
”The car worked like dream from the first lap on all areas, from straight line speed to handling. To be in the top of qualifying was very satisfying and I had a lot of traffic on my fastest lap, so we had more to give,” said Björk.
Björk started from 17th position on the grid for both races. But the Swede was never able to take part in the first race due to an electrical problem. The team repaired the problem ahead of the second race which saw Björk finishing 15th.
”The second race was as tough as we expected, especially as the track was slippery after some light rain. I fought hard and while 15th position isn’t telling the entire story of our weekend, I am still pleased. This was a one-off entry and we showed that we are on par with Chevrolet, Honda and the others in terms of performance. That is what we bring with us back home to Sweden,” said Björk.
The WTCC race in China marked the last race of 2013 for Volvo Polestar Racing. Next up is the 2014 V8 Supercars premiere in Australia on March 2nd at Adelaide Street Circuit.
”We are very pleased to see that Thed and the car are competitive. We suffered a bit from not having raced in the championship since 2011, but that was to be expected. It was also great to see that the enthusiasm for racing in China has grown a lot since last time we were here at Tiamna in 2011,” said Alexander Murdzevski Schedvin, Motorsport Commercial Director at Volvo Cars.

The new Volvo Drive-E powertrain family – world-leading engine output versus CO2 emissions
Volvo Car Group’s new two-litre, four-cylinder Drive-E powertrain family can truly be considered as offering customers a world-class blend of drivability and low CO2 emissions. The Volvo S60 T6 with 306 horsepower and the new 8-speed automatic is the first car in this segment that delivers over two horsepower per gram CO2 from a combustion engine only – and the D4 with 181 horsepower and manual gearbox is the first diesel car on this power level in the premium D-segment with CO2 emissions under 100 g/km.
“During the development phase of our Drive-E powertrains, we promised to bring efficient driving pleasure into a new dimension. The official European NEDC certification now confirms that we outperform competitors when it comes to power versus CO2 emissions”, says Derek Crabb, Vice President Powertrain Engineering at Volvo Car Group.
With 306 hp and CO2 emissions at 149 g/km (6.4 l/100 km) the Volvo S60 T6 becomes the first car in the segment that offers the driver over two horsepower per gram CO2. The car accelerates from 0-100 km/h in 5.9 seconds.
Petrol engine with compressor and turbo
The new two-litre, four-cylinder T6 engine features both a supercharger and a turbo charger. Using the supercharger to fill in the bottom end torque gives the petrol engine a big, naturally aspirated feel. The mechanically linked compressor starts to function immediately at low revs, while the turbocharger kicks in when the airflow builds up.
“We have created a range of smaller, more intelligent engines with power curves that give exciting driveability compared with engines with more cylinders. At the same time we continue to reduce fuel consumption and CO2 emissions,” says Derek Crabb.
The Volvo S60 T5 with 245 hp and the new 8-speed automatic is also exceptionally competitive. CO2 emissions are down at 137 g/km, which translates into fuel consumption of 5.9 l/100 km.
Class-leading diesel at 99 g/km
The Volvo S60 D4 with 181 horsepower and manual gearbox has class-leading CO2 emissions at 99 g/km, which translates into fuel consumption of 3.8 l/100 km. A Volvo V60 D4 with up to 17-inch tyres also breaks the 100-gram barrier according to the NEDC certification with CO2 emissions at 99 g/km.
The Drive-E diesels feature world-first i-ART technology with pressure feedback from each fuel injector instead of using a traditional single pressure sensor in the common rail.
Each injector has an intelligent chip on top of it that monitors injection pressure. Using this information, the self-adapting i-ART system makes sure that the ideal amount of fuel is injected during each combustion cycle.
“The combination of injection pressure at 2,500 bar and i-ART technology gives the customer an engine with high performance, improved fuel economy and considerably lower emissions. It is a breakthrough comparable to our invention of the lambda sensor for the catalytic converter in 1976,” says Derek Crabb.
Prepared for electrification
The Drive-E engines are prepared for future electrification from the start. The compact size of the four-cylinder engines means that the electric motor can be fitted in the front or rear of the vehicle. The battery pack will be located in the centre of the car.
“The success of our V60 Plug-in Hybrid has also proved there is no contradiction between driving pleasure and low emissions. And we have already confirmed that the all-new XC90 will be introduced in 2014 with a petrol plug-in hybrid at the top of the range,” says Derek Crabb. He concludes: “The first Volvo car back in 1927 featured a two-litre, four-cylinder engine. So you can safely say that the new Drive-E powertrain family remains true to our heritage.”

Volvo completes successful study of cordless charging for electric cars
Volvo Car Group has been a partner in an advanced research project that has studied the possibilities of inductive charging for electric vehicles – and the results show that this technology for transferring energy via an electromagnetic field has a promising future.
“Inductive charging has great potential. Cordless technology is a comfortable and effective way to conveniently transfer energy. The study also indicates that it is safe,” says Lennart Stegland, Vice President, Electric Propulsion System at Volvo Car Group, and adds “There is not yet any common standard for inductive charging. We will continue our research and evaluate the feasibility of the technology in our hybrid and electric car projects.”
Inductive charging uses an electromagnetic field instead of a cord to transfer energy between two objects. An induction coil creates an alternating electromagnetic field from a charging base station. A second induction coil in the portable device picks up power from the electromagnetic field and converts it back into an electrical energy that charges the battery. This technology is common in electrical home appliances such as electrical toothbrushes but is not yet commercially available to charge electric cars.
“With inductive charging, you simply position the car over a charging device and charging starts automatically. We believe that this is one of the factors that can increase the customer’s acceptance of electrified vehicles,” says Lennart Stegland.
Research in Flanders
The completed research project, which included inductive charging for cars and buses, was initiated by Flanders’ Drive, the knowledge centre of the automotive industry in the Flanders region in Belgium. It featured a consortium of companies, including Volvo Car Group, Bombardier Transportation and the coachbuilder Van Hool. The project was partly funded by the Flemish government. Volvo Cars supplied the car for the inductive charging project: a Volvo C30 Electric with a power output of 89 kW (120 hp).
“The tests demonstrated that our Volvo C30 Electric can be fully charged without a power cable in app. 2.5 hours. In parallel with this, we have also conducted research into slow and regular charging together with Inverto, which was also a partner in the project,” says Lennart Stegland.
Volvo Cars has focus on electrification
Volvo Cars’ ambitious strategy for electrification has also resulted in the successful launch of the fast-selling Volvo V60 Plug-in Hybrid, which entered series production in 2012.
The company has initiated strategic co-operation with Siemens in order to develop electrical drive technology, power electronics and charging technology as well as the integration of these systems into electric vehicles.
