Powertrain
The SLR McLaren sports a 232 kg, hand-built, 5.4 L, supercharged, all-aluminium, SOHC V8 engine. The cylinders are angled at 90 degrees with three valves per cylinder and lubricated via a dry sump system. The compression ratio is 8.8:1 and the bore and stroke is 97 mm and 92 mm, respectively. The Lysholm-type twin-screw supercharger produces 0.9 bar of boost, the turbine rotates at 23,000 revolutions per minute, and the air is cooled via two intercoolers. The engine generates a maximum power of 626 PS at 6,500 revolutions per minute and a maximum torque of 780 Nm at 3,250 revolutions per minute.



Connected to the engine is a five-speed automatic transmission which offers three different driving modes: sport, comfort, and manual. The former offerers and additional three modes. The Electronic Stability Program (ESP) developed by Mercedes-Benz monitors traction and adjusts torque and selectively applies brakes to maintain driver control and prevent vehicle spin.
