4-cylinder, electric turbo from RWD Mercedes-AMG SL43 Formula 1.

11/04/2022 Drive Pilots

This week Mercedes-AMG unveiled a new entry-level version of its seventh-generation SL Roadster, the SL43, and is the first SL to use a four-cylinder engine since the original 190SL of the 1950s and 60s. The SL43 is unlikely to come to the US, which is honestly humiliating because it should be the purest model in the range.

The SL43 is powered with the aid of using the identical hand-constructed turbocharged 2.0-liter inline-4 located in fashions just like the CLA45 and GLA45, however with a Formula 1-stimulated twist. This new version of the Powerplant uses an electric gas turbocharger – the first application in a production car – derived directly from a turbo in a Mercedes Championship-winning F1 car. Compared to the regular turbo, it improves throttle response across the powerband, enables more torque at shorter repetitions, and maintains boost pressure, while the turbo is powered by a 48-volt mild-hybrid system, which offers an additional 14 boost.Horsepower, way to its belt pushed starter generator. Total output is 381 hp and 354 pound-feet of torque, putting out 88 hp and 162 lb.-ft. Down from the Twin-Turbo V8-powered SL55 but the base 911 Carrera by 2 hp and 23 lb.-ft.

Unlike the V8-powered SL55 and SL63, it comes standard with a fancy all-wheel-drive system, the SL43 is rear-wheel drive. It has the same nine-speed dual-clutch automatic transmission as other new SLs, and Mercedes claims that the SL43 will reach 62 mph in 4.9 seconds and reach the SL55 from 171 mph, just 1.1 seconds and 14 mph. The SL43 comes standard with a steel suspension and is available with all performance features such as V8 models with adaptive dampers, carbon-ceramic brakes, rear-axle steering, electronic limited-slip differential, dynamic engine mounts and race. Drive mode with launch control. According to Mercedes, the SL43 is about 300 pounds lighter than the SL55.

There are some slight style differences to distinguish the four-cylinder model, but the SL43 is just as beautiful as its siblings. The lower bumper has a less aggressive design, the rear bumper exits the fake vents and the rear diffuser quad round exhaust tips. Nineteen-inch wheels are standard, but the 20s and 21s are optional and are available with the SL43 Aerodynamics package, which adds different bumper trims and modified spoilers for more downforce.

The four-seater interior of the SL43 is similar to other new SL models, with a “hyper-analog” design that includes a digital gauge cluster, a 12.3-inch central touchscreen with an electronic adjustable angle, and a sweet turbine-style air vent. Mixed with stitched leather-based and actual metallic trim. Tech systems such as Fancy Nappa Leather, carbon-fibre accents, performance bucket seats, tons of driver-assist features and augmented-reality navigation are all available.

With a little weight on the front axle, rear-wheel drive and all the performance goodies you need, the SL43 comes with a four-cylinder, but with the new SL lineup being a clean driver’s choice – and it’s definitely a little cheaper. Sadly, the SL43 is unlikely to come to the US, but there are more variants on the way. Later this year the plug-in-hybrid SL63 will be e-Performance, which can deliver 800 horsepower and may also be the PHEV version of the SL43.
