Mercedes-AMG SL gains 2.0-litre entry-level model with 375bhp
F1 cars, adds a 4cm-thick electric motor to the turbocharger shaft. It drives the turbocharger directly, which, Mercedes claims, “significantly improves immediate response from idle speed and across the entire engine speed range.”
Mercedes says it provides the SL 43 with a more dynamic driving experience, optimising acceleration and accelerator input. It also maintains boost pressure when the driver has taken their foot off the accelerator. The technology helps to propel the car from 0-62mph in 4.9sec and on to a top speed of 170mph. SL 43 models are also equipped with a nine-speed AMG Speedshift multi-clutch transmission."The electric exhaust gas turbocharger is a fascinating example of the extensive transfer between Formula 1 technology and the development of production vehicles.
“In implementing this in conjunction with our powerful M139 four-cylinder, we were also able to draw on the enormous wealth of experience of our colleagues at Mercedes-AMG High Performance Powertrains. The technology increases agility and thus driving fun, while at the same time improving the efficiency of the drive system.”
Mercedes says the SL 43 features a slightly adapted exterior design, with rounded front and rear aprons. A set of 19in alloy wheels are fitted as standard, with the option to swap to 20in or 21in instead.
