Audi has introduced two new additions to its A4 lineup, with two- and all-wheel drive models that improve fuel economy with out sacrificing performance or comfort.

One thing you can never have too many of is Audi A4 variants. The manufacturers' midrange offers a nearly-perfect combination of performance, luxury and capability. Audi's excellent sedan/wagon family is expanded by two for 2009, with the addition of two all-new drivetrain options.

The 2.0T FrontTrak pairs the 2.0 liter TFSI engine with the latest version of its high-efficiency multitronic continuously variable transmission (CVT). The combination of the lighter front-wheel drive system and CVT results in impressive fuel economy gains; the A4 2.0T FrontTrak is rated at 23 mpg in the city and 30 mpg on the highway by the EPA. This is a four percent gain over previous, similarly-equipped A4s.

For more efficient motoring with Audi's traditional quattro all-wheel drive system in place, the A4 2.0T is now also available with a six-speed manual transmission. The system is geared toward enthusiast buyers of course, and the all-wheel drive is biased toward the rear for more entertaining driving. Fuel economy comes in close to the CVT's with EPA ratings of 22 mpg city and 30 highway.

U.S. pricing for the 2.0T Front Trak starts at $31,000, and the 2.0T quattro manual comes in at $31,850.
