BMW specialist AC Schnitzer took the wraps off one of the fastest open-top sports car they have ever made, and it’s a diesel-powered Z4! That may not sound like a very delicious recipe, but if you don’t fixated too much on the ingredients, AC Schnitzer BMW Z4 Diesel actually makes a lot of sense.

I mean, at the end of the day, you want to have a powerful car that goes really, really fast, don’t you? AC Schnitzer BMW Z4 Diesel can accelerate from 0 to 100 km/h in 4.5 seconds and reach a top speed of over 300 km/h. So what difference does it make if it’s powered by petrol, diesel, or potatoes?

Another interesting fact about the AC Schnitzer BMW Z4 Diesel, officially called the ACZ4 5.0d, is that the engineers have managed to extract 430 horsepower and 840 Nm of torque from just 2.5 liters. The car is based on the Z4 sDrive 23i, but it benefits from a limited-slip diff from the previous M3, adjustable racing suspension, high-performance brakes, and a beefed-up 8-speed transmission.

Styling-wise, AC’s Z4 Diesel features a subtle carbon fiber aero kit with front spoiler, rear diffuser, boot lid spoiler and side skirts, as well as lightweight 19-inch wheels. This car is currently a one-off, but AC can make another one for you if you can come up with a check for nearly 114,000 EUR.
