2009 BMW 3 Series

Along with the carryover engines, the 2009 3 Series sedan and wagon continue to feature a standard six-speed manual and optional automatic, but now buyers of the 335i coupe or convertible can opt for BMW's new seven-speed, dual-clutch DCT transmission as well. Offering lightning-fast shifts and no loss in traction, the DCT helps the 335i post better performance numbers than its 2008 cousin. With gas prices spiraling, the 3 also features new EfficientDynamics technology to reduce fuel consumption, including (on some models) regenerative brakes, an auto start/stop function, and a shift point display -- but whether these gas-saving tweaks will be in U.S.-market cars remains to be seen.

American buyers looking for some relief at the pump will get the chance to try out one of BMW's lauded diesels. For 2009, the automaker is finally offering an oil-burning option in the form of the 335d. A 3.0L twin-turbodiesel inline-six featuring common-rail direct injection, the mill puts out approximately 286 hp and a stunning 428 lb-ft of torque, while reaching 62 mph in a respectable 6.0 sec -- just 0.4 sec behind the topline 335i. Yet despite this, according to BMW the 335d averages 35 mpg, which is 9 mpg better than the twin-turbo gas model, and 7 more than a slower, naturally aspirated 328i.

Having virtually invented the small sport sedan segment 33 years ago, for years BMW's 3 Series has had a target on its back yet (usually) manages to still come out on top. The Munich automaker's rivals aren't about to rest on their laurels, however, with Audi readying a new S4 powered by a supercharged V-6 and Infiniti rumored to be prepping a G37 sedan for next year. Yet while the competition will no doubt continue to try and knock the 3 off its throne, with a host of updates and the new diesel powertrain option, the icon will no doubt keep fighting the good fight over the years to come.
