Although short two cylinders of BMW's 3-liter six-cylinder, this new engine uses a twin-scroll turbo to produce 240 horsepower, 15 less than the six cylinder engine, and 260 pound-feet of torque, which is about 30 more than the six-cylinder. BMW has not released fuel economy numbers yet, but this new Z4 is expected to do better than the outgoing version.
