Volvo’s new Drive-E powertrains – efficient driving pleasure with world-first technology
Volvo Cars’ new Drive-E range of powertrains takes efficient driving pleasure to a new dimension in which the number of cylinders is no longer important to describe power and drivability.
The first three engines from the two-litre, four-cylinder Drive-E powertrain family will be launched in Europe in autumn 2013. The diesel version features world-first i-Art technology, and the most powerful petrol version comes with a class-leading combination of a compressor and a turbocharger.
“We have created smaller, more intelligent engines with power curves that give exciting driveability compared with engines with more cylinders yet deliver the fuel economy of only four cylinders,” says Derek Crabb, Vice President Powertrain Engineering at Volvo Car Group.

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.
Other improvements to the Drive-E petrol engines include friction-reduction measures such as ball bearings on the camshaft, high-speed continuous variable valve timing and intelligent heat management with a fully variable electric water pump.
