Volvo DRIVe low-emissions range to debut at Paris

Posted Tue Sep 9 2008 3:55 PM by Nelson Ireson

Mercedes-Benz has its BlueEfficiency line, BMW has EfficientDynamics, and now Volvo will be unveiling its DRIVe package of efficiency-enhancing technologies. A multi-faceted approach at optimizing vehicular efficiency, from aerodynamics to rolling resistance in addition to driveline enhancements, allows the DRIVe line of cars to all clock in below 120g/km CO2 emissions.

That equates to fuel efficiency ratings above 50mpg US (4.7L/100km) for all three cars in the range. The S40 and V50 DRIVe models yield 52.3mpg US (4.5L/100km) while the smaller C30 manages 53.4mpg US (4.4L/100km). All three cars are powered by the same 1.6L four-cylinder turbo-diesel engine.

Efficiency improvements are found all over the cars, first by improving aerodynamics. Lower chassis height offers a smaller frontal profile. Adding a front spoiler like that found on T5 models to the S40 and V50 enhances airflow as well. An improved grille, front-wheel wind deflectors, optimized wheel aerodynamics, underbody panels and a unique rear spoiler and rear bumper for the C30 complete the package.

Rolling resistance is lowered through the use of special Michelin tires, while higher gear ratios ensure the engine is turning at the lowest and most efficient RPMs possible. This step alone accounts for a 1.5% improvement in fuel efficiency. Finally, by improving engine cooling and minimizing parasitic loads from the power steering unit plus low-friction transmission oil, the driveline is made more efficient, so less energy is wasted as heat or friction.

The low emissions ratings ensure the cars will slot into the UK's Band B emissions profile, which is the next-to-lowest rating and offers more affordable yearly tax rates. There is no word yet regarding bringing the line to the U.S., but with the recent push among luxury carmakers toward diesel alternatives in the world's biggest car market, it is a real possibility.

Better MPG than a Prius!!!! Diesels are the stepping stone as to what is next.

Turkle- if your out there MARK MY WORDS!!!!!!

Whats more amazing is that this is ready to sell now and way out side of any box Ford thinks in, No wonder the company is for sale. Go Volvo!!!!!

Old Chinese proverb "Ah, patience young grasshopper"

It'll be here people, maybe not as a Volvo, but it will be here.

No it won't mywheelsonwalls. Ford, GM and Chrysler are not going to bring diesel cars here, only the foreign owned comapnies like Nissan, Honda, BMW etc.

NoName- My point exactly. Do you read my posts? Let me put it in caps "IT'LL BE HERE PEOPLE, MAYBE NOT AS A VOLVO, BUT IT WILL BE HERE"

You should change your name to "NoBloodyBrainsDenton". Yes that was a personsl attack but you did earn it.

Those eccentric wheels are designed for true ecologists. Those who want to exhibit with proud they've bought a fuel-efficient car.
