For the 99d, unveiled in 2011, we boosted the engine – originally from the 320d Efficient Dynamics, then the most efficient BMW model – to 140 kW/190 hp and 420 Nm, whilst simultaneously reducing CO₂ emissions from 109 to 99 grams and fitting the engine into the Z4 Coupé. The Coupé was weight-optimised and its dynamic handling improved: thanks to an AC Schnitzer racing suspension, lightweight forged alloy wheels weighing just 7.9 kg, lightweight brake discs and other measures, we reduced the unsprung mass directly at the wheels by 35 kg. As a result, the 99d was capable of speeds in excess of 240 km/h. Here you can find the 99d: https://www.ac-schnitzer.de/en/99d/
