2009 Audi A4

That model uses a 1.8-liter turbo unit that is closely related to the 2.0T in current U.S.-market Audis. It, like all of the engines in the new A4 lineup, uses direct injection. In 1.8-liter form, it produces 160 hp and 184 lb-ft of torque, and when equipped with a six-speed manual, it accelerates the A4 to 62 mph in 8.6 seconds. A Multitronic continuously variable transmission (CVT) is available as an option on front-wheel drive A4s.

The top-specification 3.2-liter V-6 sends its 265 hp and 243 lb-ft of torque to all four wheels using Audi's rear-biased Quattro system, and, with a manual 'box can hit 62 in 6.2 seconds. A six-speed automatic transmission is still under development for Quattro-equipped cars - the previous unit won't fit in the new chassis because of the new layout. The 3.2-liter uses Audi's AVS variable valve lift system, which helps improve fuel economy drastically: the new engine uses almost fifteen percent less fuel than the old one - which produced ten horsepower less.
