XTRONIC CVT Continuous Variable Transmission
XTRONIC CVT (Continuously Variable Transmission) shifts through a near-infinite number of gear ratios to keep the engine in its most efficient rpm range, allowing you to enjoy optimal fuel economy and power without any shift shock. Once you experience its “velvet-like” ride, you’ll never want to go back to a conventional system.

"...a real honey of a transmission."
