The tuning firm AC Schnitzer has unveiled its newly tuned BMW 99d at the 2011 Geneva Motor Show. The tuner unveiled the vehicle claiming that driving pleasure comes guaranteed thanks to the 190-horsepower that the vehicle's engine can pump out. This engine also allows it to jet from 0 to 60 mph in 6.9 seconds with a top speed of 149 mph. It's also fuel efficient, generating 99g/km CO2 thanks to what Schnitzer calls Efficient Performance.

The 99d draws power from the diesel engine found in the BMW Z4, and the vehicle is also lighter thanks to the employment of lightweight materials such as carbon, magnesium, and titanium. The body of the concept has also been lowered by 30 mm in conjunction with a few AC Schnitzer carbon aerodynamic components, all resulting in a reduced drag. The tuner claims that the 99d is a concept car not for sale and was developed solely as a technology platform, but as shown here, the vehicle would cost €149,000 ($206,161).
