2011 BMW AC Schnitzer 99d Concept BMW Z4 produces 188 horsepower.

This time, the 2011 BMW AC Schnitzer 99d Concept, a one-off model introduced earlier this year at the Geneva Motor Show. Though we’ve long recognized that automotive tuners can be great sources for speed, AC Schnitzer has showed its paying attention to the green movement with its BMW Z4-based 99d concept car. BMW AC Schnitzer started with the Z4 roadster and swapped in the diesel four-cylinder from the overseas 320d EfficientDynamics. Without telling us exactly how the engine was modified, we’ve learned the diesel-powered Z4 produces 188 horsepower and 310 pound-feet of torque.

The factory-stock 320d mill makes 163 horsepower and 280 pound-feet. The German tuning firm would only go as far as calling its performance enhancements “Efficient Performance,” but we’d bet there’s some ECU remapping involved. The use of lightweight materials such as carbon, magnesium and titanium has managed to drop the weight of the Z4 by 230 kg. With the extra power and a weight-shedding strategy in place, the 2011 BMW AC Schnitzer 99d goes from 0-62 mph in 6.9 seconds and can hit a top speed of 146 mph, which isn’t bad for an efficiency-minded, four-cylinder diesel. AC Schnitzer says the 99d concept consumes just 3.8 liters of diesel fuel for every 100 kilometers driven. In America, that works out to around 62 mpg.

The overall balance of the car has not changed significantly. The 99d feels lighter and more nimble than a stock Z4, but 2011 BMW AC Schnitzer 99d did not change anything with respect to the favorable characteristics of the two-seater. The AC Schnitzer 99d is still a cornering champion, exhibiting little body roll and plenty of grips. There’s no waiting for the rest of the car to make it through the turn because you’re practically sitting at the back of the roadster. The only penalty for this sublime handling is the ride quality that can be quite rough on patched asphalt roads. Comfort is not something you would immediately search for in the AC Schnitzer 99d, but the ride is far from bumpy or hard.”

As the 2011 BMW AC Schnitzer 99d is just a concept car, it’s not for sale. In its current form, the 99d reportedly would cost around 149,000 Euros, or $210,000. And that’s a large amount of dough, though we’re expecting Efficient Performance technology to start trickling into the product line in the near future.
