Equipped with the BMW Advanced Diesel with BluePerformance, the 335d Sedan is set to be unveiled at the 2008 Detroit Auto Show alongside the the X5 xDrive35d, but the Green Car of the Year nomination may cause BMW to bump it up.
The 335d Sedan is powered by a 3-liter turbodiesel that uses two turbochargers in series. At low speeds, a small turbocharger is able to spin up quickly, and without lag. As the engine gains speed, a larger turbo comes online, taking over for the small turbo.
It doesn't take much power to motivate a tiny two-seater such as the Smart ForTwo. Its 1.0-liter, three-cylinder engine outputs a mere 70 horsepower. The ForTwo hums along to the tune of 33 city and 41 highway mpg, with equally stringent emissions.
The EPA has put the smart ForTwo at the top of its current list of the most economical cars without hybrid drive. The US authority confirms independent European studies that had already established the clever two-seater as the most economical car.
The all-new 2009 Saturn Vue Hybrid uses General Motors' Two-Mode Hybrid, which we've seen on the GMC Yukon Hybrid. The Vue is unique because it is the first front-wheel-drive application of the system.
In the first mode, at lower speed and lighter loads the Vue 2 Mode Hybrid operates in one of three ways depending on conditions and battery charge level: all-electric power, internal combustion engine power, or a combination of the two. All reverse operation is driven solely by the electric motors.
The second mode is used primarily to optimize fuel economy at highway speeds to optimize fuel economy. It provides electric assist in addition to six-cylinder power when conditions demand it, such as trailer towing and climbing steep grades, and to allow the engine to run at its most efficient point under less demanding conditions.
The Ford Fusion Hybrid (and Mercury Milan Hybrid) utilizes technology similar to what we've seen on the Ford Escape and Mercury Mariner. The Fusion will have an expected range of 700 miles of city driving on a single tank and the ability to operate in purely electric mode at speed of up to 47 mph, thanks to a smaller, lighter battery.
