The rear-wheel drive 335d sedan is powered by a 3.0-liter, twin turbo, inline six-cylinder advanced diesel engine that puts out 265 horsepower and 425 pound-feet of torque. A six-speed automatic is the only transmission choice. This combination provides 0-60 acceleration in 6.0 seconds (BMW AG test results), while delivering an impressive 36 mpg on the highway. Standard safety features include six airbags, four wheel anti-lock disc brakes with adaptive brakelights, bi-xenon headlights, active anti-whiplash head restraints, electronic traction and stability control and run-flat tires. The 335d is unchanged for 2011.
