Sub-120g/km CO2 cars – here’s another one, this time from Volvo

There are now virtually incessant announcements about new cars with low CO2 emissions, and the latest is from Volvo.

The new Volvo C30 ‘Efficiency’ makes its global debut at the Frankfurt Motorshow on 11th September and is powered by a 105PS 1.6-litre turbodiesel engine. The current Volvo C30 1.6D offers a combined fuel consumption of 57.6mpg and emits 129g/km of CO2, whereas the new model has improved fuel consumption (62.8mpg) and reduced CO2 emissions to below 120g/km.

This has been achieved by the Volvo C30 Efficiency having a reduced chassis height, a new rear roof spoiler, a new rear bumper, underbody panels, optimised engine cooling and optimised 16-inch wheels. The unique gearbox has revised higher gearing in 3rd, 4th and 5th gears. Low friction tyres and transmission oil have been used and the steering servo assistance and engine management have been optimised.

The Volvo C30 Efficiency becomes Volvo’s first model to gain a B-band VED tax rating and will also be exempt from the London Congestion Charge, if the proposed changes to the scheme go ahead next year.

Early 2008 will also see the introduction of a new 2-litre turbodiesel (2.0D) automatic transmission with Powershift technology for the Volvo C30, S40 and V50 model ranges. The Powershift gearbox consists of two clutches that work in parallel and, since there is no disruption in torque delivery during the gearchanging process, gearshifts are instantaneous and the fuel efficiency rating is higher, delivering improved fuel consumption compared to a standard automatic gearbox.

“We are firmly committed to lowering the fuel consumption of our conventional petrol and diesel engines. By doing this we will continuously reduce the overall CO2 emission level for our whole model range,” says Magnus Jonsson, Senior Vice President Research and Development at Volvo Cars.

It’s interesting to see how legislation such as the proposed 120g/km limit for Congestion Charge exemption is forcing engineers to implement all sorts of creative ways to maximise fuel economy and reduce emissions. It’s a shame that we’ve had to rely on Ken Livingstone to bring this about.

The low CO2 emitting Volvo C30 and the new diesel Powershift transmission for the Volvo C30, S40 and V50 will be introduced during 2008.

Volvo will also reveal its future hybrid plans at the Frankfurt Motorshow.
