Mercedes-AMG SL 43 Tech is Derived from F1 Race Cars


Mercedes-Benz just unveiled its new convertible, the Mercedes-AMG SL 43. The seventh-generation SL boasts high performance, more advanced tech, and a new level of enjoyment while driving. However, purists have lately reacted to the decision of the German automaker to skip the six- and eight-pot engines in favor of a turbocharged four-cylinder in this specific model.

The AMG SL43 is the entry-level version of its range. Beneath the hood of the car lies a measly 2.0-liter four-cylinder engine, but don’t let that fool you because the integration of a turbocharger with a mild-hybrid 48-volt electric motor allows it to produce up to 376 hp and 479 Nm of torque. All that power is distributed via a nine-speed automatic transmission, which in turn lets the convertible top at 275 km/h and accelerate from 0 to 100 km/h in just 4.9 seconds.

According to Mercedes, the technology used in the AMG SL 63’s engine was derived from its F1 cars. It mainly adds a 1.5-inch big electric motor to the turboshaft of the car to maximize its output. Quoting the automaker, the configuration ‘significantly improves immediate response from idle speed and across the entire engine speed range’. That means even if the driver lifts his/her foot off the accelerator, the boost pressure is still maintained by the turbo.

“The electric exhaust gas turbocharger is a fascinating example of the extensive transfer between Formula 1 technology and the development of production vehicles,” Mercedes chief technical officer Jochen Hermann said.

In addition to the power boost, the technology transferred from Mercedes F1 cars promises to deliver an enhanced driving experience to the sassy SL.
