Here we have a classic on our hands, a 1999–2003 BMW Z8 roadster fixed up by the guys at Senner Tuning. The German based aftermarket company decided to give a small performance package to increase the numbers even further. Stock, the BMW Z8 holds the E39 M5 5.0-liter V8 engine that produces 400 horsepower and 500 Nm of torque. With the Senner Tuning additions of a new air filter, custom exhaust, and ECU tune to bring it all together, new figures show 450 HP and 535 Nm of torque. While these modifications weren’t really necessary, the small sports car can now hit a top speed in excess of 300 km/h or 186 mph.
