BMW has just released an all-new high-performance version of the Z4 at the Detroit Auto Show. Called the Z4 sDrive35is, this roadster’s twin-turbo 3.0-liter inline-six gets a new air intake system and higher boost pressure to produce a bump in power. With an extra 35-hp and 32 ft-lbs of torque, the new model makes 335-hp and 332 ft-lbs in total. An overboost function will deliver an added boost of torque, bringing the total torque number to 369 ft-lbs. That’s just 11 ft-lbs shy of the M5’s V10 motor.
The added power make the Z4 sDrive35is noticeably faster with a 0-60 mph time of just 4.7 seconds, thanks in part to BMW’s impressive new 7-speed dual-clutch transmission.
In addition to the engine upgrades, this new model gets M Aerodynamics and an adaptive M Suspension that uses electronically controlled shock absorbers as well as a ride height which has been lowered by 10mm. A set of 18-inch wheels come standard with light-weight 19s optional.
