Volvo's new two-litre, four-cylinder Drive-E powertrain family offers customers a world-class blend of drivability and low CO2 emissions. The D4 with 181 horsepower and manual gearbox is the first diesel car with this level of power output in the premium D-segment with CO2 emissions under 100 g/km.

The Volvo S60 T6 FWD with 306 horsepower and the new eight-speed automatic is the first car in the segment that delivers over two horsepower per gram of CO2 from a combustion engine only. The car accelerates from 0-62 mph in 5.9 seconds.

"During the development phase of our Drive-E powertrains, we promised to bring efficient driving pleasure into a new dimension," explained Derek Crabb, Vice President Powertrain Engineering at Volvo Car Group. "The official European NEDC certification now confirms that we outperform competitors when it comes to power versus CO2 emissions."

The new D4 FWD can be ordered now and is available in the new S60, V60, XC60, V70, XC70 and S80. It is also available to order with the new eight-speed automatic. The new T6 engine is expected to be available during 2014.

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 74.3 mpg. A Volvo V60 D4 with up to 17-inch tyres also breaks the 100-gram barrier according to the NEDC certification with CO2 emissions the same as its’ sister saloon 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.

Mr Crabb added: “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.”

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.”
