Powertrain Options and Availability
BMW has offered two inline six-cylinder engines for the Z4. In the 2.5i, a 2.5-liter engine produces 184 horsepower, while the 3.0i holds a 3.0-liter six that makes 255 horsepower. Four transmissions have been available: a standard five-speed manual for the 2.5i (six-speed for the 3.0i), optional five-speed automatic for both, or a six-speed Sequential Manual Gearbox that combines the merits of a manual and automatic, and has no clutch pedal. For 2006, the 215-hp 3.0i replaces the 184-hp 2.5i as the base convertible. New for '06 is the 255-hp 3.0si in convertible and coupe form.
