[1] For model year 2008, the EPA has revised the way the estimated fuel economy rating is determined. For example, the combined fuel economy range for the comparable class of vehicle in 2007 was 9–32 mpg, but under EPA’s revised fuel economy test procedures, the comparable class combined range for 2008 may be 10–30 mpg according to EPA’s preliminary estimates.

5-speed Automatic Transmission and Manual Shift Mode with Downshift Rev Matching
Electronically controlled 5-speed automatic and manual shift mode offer sequentially selected manual gearshifts as well as Downshift Rev Matching that automatically opens the throttle when downshifting to match the rpm, resulting in smoother gear changes.

5-speed Automatic Transmission and Manual Shift Mode with Downshift Rev Matching
Begin with five well-chosen gear ratios and a driver-adaptive learning algorithm in automatic mode that electronically tailors the transmission's response to your unique driving style. Flick the shifter sideways and you're in manual mode, which allows sequentially selected manual gearshifts and matching revs on downshifts.
