The 335i's engine is little changed from the past model year, using direct injection, a twin-scroll turbo, and variable valve timing to generate 306 horsepower. Elements such as regenerative braking help the 335i get fuel economy in the high 20s.
The standard BMW shifter controls an eight-speed automatic transmission. A six-speed manual is also available, each as no-cost options. A sport version of this eight-speed automatic can also be optioned.
