the M40i version is particularly potent, thanks to its 3.0-liter turbocharged 6-cylinder engine with a muscular 382 horsepower. This particular Z4 M40i is very desirable, as it's equipped with the Handschalter Package which adds a 6-speed manual transmission! It's also finished in an attractive Alpine White over Cognac color combination, and it's well-equipped with the Premium and Driving Assistance packages.  Power comes from a 3.0-liter turbocharged straight-6, rated at 382 horsepower and 369 lb-ft of torque. Output is sent to the rear wheels via a 6-speed manual transmission.
