GOTHENBURG, Sweden, Aug. 16, 2013 / PRN=KYODO JBN/ --
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.

"We have created smaller, more intelligent engines with power curves that
give exciting drivability compared with engines with more cylinders, yet
deliver the fuel economy of only four cylinders. In addition, by adding
electrification such as plug-in hybrid technology, we will reach power figures
in the V8 territory," says Derek Crabb, Vice President Powertrain Engineering
at Volvo Car Group.
Drive-E diesels will range from 120 to 230 hp. Petrol versions will start
at 140 hp and go all the way up to 300-plus hp.
Several levels of turbo charging open up the flexibility to cover the whole
range, from fuel-efficient derivatives through to high power and torque
variants. In order to cover all customer requirements, some engines will also
gain added performance via electrification or other spearhead technology.
Three DRIVE-E engines
Initially, the new S60, V60 and XC60 will be available with three engines
from the new engine family: the 306 hp petrol turbo T6, the 245 hp T5 and the
turbo diesel D4 with 181 hp. A new 8-speed automatic gearbox contributes to a
refined drive and excellent fuel economy. The T5 and the D4 are also available
in the new Volvo V70, XC70 and S80.
New eight-speed automatic gearbox
To deliver the desired responsive, smooth and fuel-efficient drivability,
the engines are teamed either with a new eight-speed automatic gearbox or an
enhanced six-speed manual, tuned for improved fuel economy.
"The sophisticated Drive-E technologies give the customer high performance,
improved fuel economy, considerably lower emissions and a powerful sound
character. Our four-cylinder engines will offer higher performance than today's
six-cylinder units and lower fuel consumption than the current four-cylinder
generation," says Derek Crabb. He adds:
"If you take a four-cylinder Drive-E engine versus any six-cylinder engine,
there's a massive weight and size reduction for the same power. Fuel economy
savings are anything from 10 to 30 per cent, depending on which engine you're
comparing it to."
Petrol engine with compressor and turbo
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.
Prepared for electrification
The Drive-E engines are prepared for future electrification from the start.
Key components, such as the Integrated Starter Generator, can be connected
easily - and 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.
