Seven most economical models presented Volvo at the Geneva Motor Show 2009, on the 5th March begins. The "Drive" versions to highlight the best value of their respective classes in CO2 emissions. They have diesel engines in combination with manual transmissions and reduced rolling and air resistance values. They are available in three CO2 emission levels: 120, 140 and 160 grams per kilometer - so they match the taxation classes and legal support programs, which exist in some European countries.
With start-stop system under 120 grams
In early 2009 Volvo Drive versions of bringing C30, S40 and V50 on the market that are equipped with a start-stop system. The C30 will emit with its 1.6-liter diesel engine only 104 grams of CO2 per kilometer, which corresponds to a consumption of 3.9 liters per 100 kilometers. The larger S40 and V50 are at 107 grams
The start-stop system has a backup battery, the extra capacity is to start the engine very quickly. In addition, the radio continues run correctly, when the engine is off. However, the air conditioning goes back to stand-by mode to save power. With the extra battery, the system creates, according to Volvo up to 175,000 Start / Stop cycles.
Regenerative Battery Charge
Another saving feature is the so-called regenerative battery charging. An electronic controller allows the generator only produce electricity when the vehicle rolls or without load the driver brakes. In contrast, acceleration phases is the "dynamo" inactive - as long as the battery charge allows.
The physical background is as follows: When a current generator, then there is a force which counteracts the drive force introduced. The generator slows down the engine so. Because of the Volvo but only in overrun phases generate electricity, falls off this loss and thus supposedly two to three percent fuel economy.
Big Cars, Small Displacement
Significantly more savings potential it offers, however, fit a smaller engine. Volvo has the courage to actually for the compact class 1.6-liter turbo diesel with 80 kW/109 hp developed even now employ in the upper middle class, in the V70 and S80 models.
He may well not be good for the best values in performance, but probably for a low consumption. The Swedes promise up to 18 percent advantage over the two-liter diesel. Both models will consume only 4.9 liters per 100 kilometers and produce 129 grams of CO2 per kilometer. Modified gear ratios in third, fourth and fifth gears, low rolling resistance tires, electric power steering pumps and better aerodynamics complete the austerity measures.
SUV Without Booze
Only six liters of diesel per 100 kilometers, the two-drive versions of the Volvo SUV XC 60 and XC70 consume. They have the new 2.4-liter diesel of the company, but in a throttled to 129 kW/175 hp version.
The four wheel drive was the saving efforts of the engineers also a victim, but for the main purpose of the two family-friendly crossover, the front-wheel drive sufficient doubt.
