Volvo’s new engine family went into production at the company’s engine plant in Sweden earlier this year. The new engine family will help Volvo gain technical independence from companies like Ford, with which it currently shares its engines.
Details of the first cars to get the new engines have now been revealed. The Volvo S60 T6 FWD will now use a 2.0 litre engine from the new engine family, officially called the ‘Drive-E’ family. The 2.0 litre direct injection engine is equipped with both a Roots supercharger and a turbocharger, with the supercharger filling in the bottom end of the torque curve, and the turbocharger kicking in later when the airflow builds up.
This 2.0 litre engine is mated to a new 8-speed automatic gearbox, which means the Ford Getrag Powershift dual clutch transmissions have been replaced as well. 0 to 100km/h takes 5.9 seconds thanks to 302 horsepower and 400Nm of torque.
The T5 tuning of the 2.0 litre turbo makes away with the supercharger and relies solely on a turbocharger to do 241 horsepower and 350Nm of torque. 0 to 100km/h takes 6.2 seconds. This isn’t a significantly hike in horsepower over the Ford-based T5 engine available in Malaysia but 30Nm more torque.
There’s also the D4, a diesel motor that does 181 horsepower and 400Nm and hits 100km/h in 7.5 seconds. It has i-ART technology which uses 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. Injection pressure is 2,500 bar.
The Drive-E engine family are all dimensionally similiar, so they can be built on the same assembly lines. However, the engine blocks use different materials depending on whether it’s a petrol or diesel engine, and while the cylinder heads share some DNA, they are different as well.
