Take for example Tuningwerk. They’re not even the most popular tuner around but even they have some incredible products to consider.

The Tuningwerk NR Z4s is something of great idealism; it retains the relatively discrete look of the BMW Z4 yet it’s dripping the menace of performance.

Here are the highlights on performance. The 3.0 liter 6 cylinder twin-turbocharged engine now develops 550 horsepower and 553 lb-ft of torque.

The power boost is so consistent that the tuner has had to even do a few modifications to the dual-clutch automatic transmission in the Z4.

Speaking of modifications, we’re not told exactly what they are to make these changes happen. That’s a little unpleasant but we couldn’t care less because of the figures.

Thanks to all that grunt and mods, acceleration from 0 to 62 takes 3.7 seconds and the top speed now goes beyond 192 mph.

Mind you, in order to achieve these figures you’ll need to run 98 octane fuel. Still, it’s a minor trade off.

Oh and don’t worry about the rest of the car. The BMW Z4 chassis can easily take the power and the brakes have been upgraded and, if desired, carbon ceramic ones can be fitted.

The German sense of responsibility goes even further as Tuningwerk even offer the option of a direct handover of the NR Z4s which includes driver training.
