Mercedes AMG SL 43 launched as an entry-level grand tourer, with F1 tech

The Mercedes AMG SL 43 will slot in below the SL 55 and SL 63.  It also features a turbocharger technology that is directly derived from Formula 1.

The Mercedes AMG SL 43 is the new entry-level grand tourer in the SL lineup. Unlike V-8 powered siblings SL 55 and SL 63. The SL 43 gets a turbocharged inline-four. Mercedes claims that the turbocharger features a technology that is directly derived from its F1 car.

The turbocharger in the Mercedes Benz SL 43 gets an electric motor, alongside a typical exhaust gas-plumbing. This inch-a-half thick electric motor is mounted on the shaft, between the turbine and compressor wheel. The whole point of this setup is that the motor will spin the compressor wheel before the exhaust gases do. Thus, in effect, it reduces turbo lag and a near-immediate response when the driver floors the pedal. It even helps maintain the boost pressure when de-accelerating.

Theres also an additional 48 V belt-driven starter generator that helps produces some additional 12 hp boost. Mercedes claims that the rear-wheel-drive SL 43 can do 0-100 kph in 4.9 seconds with its top speed rated at 270 kph.

Aesthetically, the Mercedes AMG SL 43 gets minor changes on the exterior. This includes rounded tailpipes, a simplified rear bumper, and a reshaped front bumper. The SL 43 rides on standard 19-inch wheels, with 20-inch and 21-inch as options, as well.
