Just the Facts:
Hamann modified the car's ECU and added a sport exhaust for 355 hp and 398 lb-ft of torque.
Top speed, no longer limited, is now 177 mph.
The car also has front and rear spoilers, revised bumpers and a 1.18-inch lowering kit.
LAUPHEIM, Germany Hamann, a tuner known for extreme modification packages, has unveiled a kit that works on both the looks and performance of the 2011 BMW Z4.
The German tuner specifically developed a performance package for the Z4 sDrive35i, which has a twin-turbocharged 3.0-liter inline-six developing an even 300 horsepower and 300 pound-feet of torque. By modifying the vehicle's ECU and adding a sport exhaust system, Hamann was able to up output to 355 hp and 398 lb-ft of torque that's available between 1,300 and 5,000 rpm. Speed is also no longer electronically limited to 155 mph, so this Bimmer won't stop screaming until it hits a top speed of 177 mph.
The car's aerodynamics are improved with the addition of a front spoiler complete with LED daytime running lamps, side skirts, a rear spoiler and revised front bumper. Lightweight three-piece alloy wheels are part of the package and are wrapped in tires that are 235/30ZR in the front and 295/25ZR in the back. A 1.18-inch lowering kit helps finish off the vehicle's new stance.
Some subtle interior upgrades like an aluminum gear shifter and new floor mats are also included, and Hamann is happy to deck the interior out in handmade leather on request.
