During the first half of 2009, Volvo Cars
will launch a variant of the new Volvo XC60 with front-wheel drive, an
upgraded Euro 5-compliant 2.4-litre diesel engine, featuring 175
horsepower, 420 Nm of torque and CO2 emissions of less than
170 g/km. "We've increased the
engine's performance by 12 horsepower and 80 Newton metres of torque. At
the same time we have succeeded in cutting fuel consumption. This
highlights the immense potential of conventional drivelines to deliver
continued reductions in carbon dioxide emissions," says Magnus Jonsson,
Senior Vice President, Research & Development at Volvo Cars.
"This is the first step in a determined
drive towards systematic reduction of CO2 emissions from our
conventional drivelines. The next stage for the XC60 is a micro-hybrid
with the potential for reducing emissions to about 140 g/km," adds
Magnus Jonsson.
The new Volvo XC60 currently has a
choice of a six-cylinder turbocharged T6 engine producing 285 PS, as
well as two five-cylinder turbodiesels: the D5 with 185 PS and the 2.4D
with 163 PS. Four-wheel drive (AWD) with Instant Traction is fitted as
standard to all these variants. The Volvo XC60 is available to order now
and will be launched in UK dealer showrooms 15/16 November 2008.
In 2009, the driveline range will be expanded with a front-wheel drive
version of the 2.4D, upgraded to produce 175 horsepower and 420 Nm of
torque.
With a manual gearbox, CO2
emissions will be less than 170 g/km and fuel consumption approximately
41.4 mpg. The corresponding figures with automatic transmission will be
approximately 38.7 mpg and 193 g/km.
In addition to front-wheel drive, a
variety of smaller improvements contribute to the attractive fuel
consumption and CO2 figures.
Volvo Cars' powertrain experts have
reduced internal friction and pump losses in the diesel engine. The
pressure drop in the intake and exhaust system has also been reduced.
Injection pressure has been increased with the next generation of
high-pressure diesel pumps and the fuel-injection strategy has been
refined through the introduction of Piezo-based injectors.
Furthermore, the engine has lower
compression, more efficient combustion and the latest generation of
engine management, whilst the single turbocharger has been optimised to
produce high torque from low revs. |
