Each of these powertrains delivers satisfying performance with the standard 6-speed manual transmission--including a linkage that's still among the best in the business--but the 7-speed dual-clutch (DCT) gearbox in the sDrive35i is a significant step above the 6-speed automatic that's offered in the base model. The DCT shifts very quickly, matches revs for downshifts, and does a great job of maintaining a smooth flow of power. Acceleration from zero to 60 mph happens in just 5.0 seconds with the DCT, while top speed with the available Sport Package is 150 mph
