The new ZF eight-speed (yes, eight-speed) automatic transmission delivers quicker acceleration and precise, smooth shifting, enhancing ride quality to luxury car levels. Standard on all models, it features on-the-fly shift map changing, with manual shifting capability and Electronic Range Select using steering-wheel paddle controls. More than 40 individual shift maps for specific conditions optimize shift quality and shift points for fuel economy, performance, and drivability. Gear changes are nearly imperceptible due to the evenly spaced gear steps between each gear ratio. Internally, the transmission has four gear sets and five shift elements (multi-disc clutches and brakes). Only two shift elements are open at any time. With fewer open shift elements, drag losses due to multiple parts rotating relative to one another are reduced, improving fuel efficiency.
