The all-new A8 and updated Q7 won't be the only vehicles in Audi's line-up to benefit from the automaker's new eight-speed gearbox. According to dealer order guides released for the 2011 model year, the octo-cog-swapper is set to proliferate throughout the Audi line-up in the next year, with the automaker aiming for around 70% of it U.S. sales volume to come equipped with the new gearbox.

For the 2011 model year, the A4 2.0 TFSI quattro sedan and Avant will come packing the eight-speed tranny, along with the A5 2.0 TFSI quattro coupe and cabriolet (the manual six-speed will only be available on the coupe). In addition, the revised Q7, with its new high- and low-output 3.0-liter supercharged V6s (cribbed from the S4 and A6), will replace the 3.6-liter V6 and 4.2-liter V8 for the 2011 model year. Both engines, along with the new 3.0-liter TDI, will come equipped with the eight-speed auto.

Finally, Audi quietly revealed the 2.0 TFSI inline-four-equipped Q5 at the New York Auto Show, and part of the new package will also include the eight-speed 'box.

Sales of the eight-speed automatic-equipped models will begin this fall, each delivering improved fuel economy, quicker downshifts and, thanks to its compact packaging, no additional weight gain over the standard six-speed tiptronic.
