Volvo E-Drive Powertrain Family Offers World-Leading Output and Low CO2 Emissions

Volvo Car Group is extremely proud of its new two-litre, four-cylinder Drive-E powertrain family, and honestly speaking so are we. The reason in simple words would be – world-leading output with low CO2 emissions. In this post we would get to know about the E-Drive family of engines in detail. “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. First up is the diesel family.Volvo S60 is powered by Volvo’s D4 engine which puts out 181 bhp. The car features a manual gearbox and emits 99 g/km of CO2, making it the first diesel car with this level of power output and under 100 g/km CO2 emissions, in the premium D-segment. Volvo V60 powered by the same D4 engine also falls in the under 100g/km CO2 emission category with CO2 emissions the same as its’ sister saloon at 99 g/km, according to the NEDC certification.

Each injector is fitted with an intelligent chip that monitors injection pressure and using the same, the i-ART system calculates the right amount of fuel to be injected during the combustion cycle, ensuring class world class performance. “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. Coming to the petrol engines now, the new two-litre, four-cylinder T6 engine features both a supercharger and a turbo charger. The supercharger ensures that there is no lack of bottom end torque, giving a feel of big-displacement naturally aspirated engine. The compressor which is linked mechanically to the system kicks in immediately at low revs, while the turbocharger starts its job when there is enough airflow. The best example is the Volvo S60 T6 FWD with 306 horsepower and the 8-speed automatic gearbox. It is the first car in its segment that delivers over two horsepower per gram of CO2 from a conventional combustion engine. “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. Interestingly the whole Drive-E family of engines are electrification-ready meaning Volvo could turn them into hybrid systems at their own will. “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.”
