|Volvo C30 Efficiency.|
In 2008, Volvo Cars will introduce a Volvo C30 1.6-liter turbodiesel with fuel consumption of less than 4.5 l/100 km (52.3 mpg US) and CO2 emissions below 120 g/km.
The Efficiency version of the C30 1.6D reduces consumption by more than 8%, or 0.4 l/100 km from 4.9 l/100 km—the official figure for the C30 1.6D that is available on the market today.
Volvo engineers achieved the fuel consumption reduction through measures within four main areas:
Aerodynamics. The Efficiency has reduced chassis height, a new rear roof spoiler, a new rear bumper, underbody panels, optimized engine cooling and aerodynamically optimized 16-inch wheel rims.
Rolling resistance is reduced with a new generation of low friction tires.
Higher gearing. The unique gearbox variant has revised gearing on 3rd, 4th and 5th gears.
Powertrain efficiency increase. This includes new low-friction transmission oil, optimization of steering servo assistance and engine management optimization.
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.
This is a science of small adjustments and gains. Many systems and details in a car model have been dimensioned to suit all engine variants, from the smallest diesel to the most powerful petrol unit. This gives possibilities for fine adjustments to individual engine variants, particularly the smallest alternatives.—Magnus Jonsson, Senior Vice President Research and Development, Volvo Cars
In Sweden, a conventional car with carbon dioxide emissions of 120 g/km or less is classified as an environmental car. This entitles private new-car buyers to a state-provided cash-back of SEK 10,000 (US$1,400).
|The Getrag-Ford Powershift transmission.|
Powershift. Also in early 2008, Volvo Cars will introduce a version of the new Getrag-Ford dual-clutch automated manual transmission, demonstrated at the 2006 Frankfurt International Motor Show.
Getrag-Ford Transmissions is a 50:50 joint venture between Getrag and Ford.
In the Powershift, two manual gearboxes work in parallel and are controlled by separate clutches arranged on two main shafts. One main shaft operates the odd gears while the other operates all even gears. Since there is no disruption in torque delivery during the gearchanging process, gearshifts are instantaneous and the efficiency rating is higher.
Powershift cuts fuel consumption by approximately 8% compared with current automatic transmissions, thereby providing the functionality of an automatic transmission with about the fuel economy of a manual. In the Volvo family, it will be available in the Volvo C30, S40 and V50 with the 2-liter turbodiesel (2.0D) engine. Ford also plans to apply the transmission in its other brands.
