Whereas Mercedes-Benz has introduced plans to go EV-only the place markets enable by 2030, with a rising lineup of electrical automobiles already on sale, it isn’t giving up on inside combustion engines simply but – particularly relating to the AMG efficiency division, which is utilizing electrification to extract large energy from fuel motors. The most recent mannequin to get the AMG E Efficiency plug-in hybrid therapy is the SL roadster, making historical past as each the primary PHEV droptop from Mercedes and essentially the most highly effective SL of all time.
The powertrain setup within the new 2024 Mercedes-AMG SL63 S E Efficiency is extraordinarily just like the one within the GT 4-Door Coupe. AMG’s tried-and-true twin-turbo 4.0-liter V8 is paired with a 6.1-kWh battery pack and an electrical motor mounted straight on the rear axle. The battery pack can be situated simply above the rear axle for optimum weight distribution. The electrical motor by itself makes 201 horsepower and 236 pound-feet of torque and is built-in right into a two-speed transmission and limited-slip rear differential; the engine itself makes use of the identical 9-speed computerized because the common SL.
Whole output is a whopping 805 hp and 1,047 lb-ft of torque, a rise of 228 hp and 457 lb-ft over the nonhybrid SL63. (The engine by itself is 26 hp and 37 lb-ft up from the common SL63, too.) Mercedes says the SL63 S E Efficiency will hit 2.8 seconds, 0.7 seconds faster than the gas-only SL63. That additionally makes it a smidge faster than the GT63 S E Efficiency 4-Door Coupe, which has 831 hp and 1,084 lb-ft and hits 60 in 2.9 seconds.
Integrating the electrical motor into the rear axle permits for a extra direct efficiency enhance, and it might additionally energy the entrance axle due to the variable 4Matic all-wheel-drive system’s driveshaft and mechanical connection. Mercedes says the high-density battery makes use of Components 1–impressed expertise and has been designed for quick responses and repeated use, so most electrical energy is at all times accessible. Like AMG’s different PHEVs, the battery even recharges itself the more durable you drive.
There are 4 totally different ranges of regenerative braking, with greater than 100 kW of power in a position to be recuperated again into the battery, and the strongest setting permits for one-pedal driving like in an EV. AMG received’t say how a lot electrical vary the SL63 S E Efficiency may have, but it surely’s unlikely to be better than a dozen miles; clients can plug in and cost up the automotive with a 3.7-kW onboard charger.
The SL63 S E Efficiency comes commonplace with the SL’s fancy Lively Journey Management suspension, with makes use of hydraulics instead of standard anti-roll bars to remove physique roll and enhance dynamics. Additionally commonplace are carbon-ceramic brakes, rear-wheel steering and eight totally different drive modes, together with a battery maintain mode that makes use of the engine to take care of the battery cost.
Other than the cost port within the rear bumper, you’ll be able to spot an SL63 S E Efficiency by the crimson badge outlines and grooved exhaust ideas. AMG tweaked the SL’s lively aerodynamics for the hybrid, together with 5 new angles for the rear spoiler. Aside from new hybrid pages and designs for the infotainment system, the inside is similar as effectively. Mercedes not too long ago expanded the provision of the SL’s Manufaktur choices, with heaps extra particular paints and leather-based colours to select from just like the Mid Eire Inexperienced Magno in these photographs.
Mercedes says the SL63 S E Efficiency will go on sale within the U.S. in some unspecified time in the future subsequent 12 months for the 2024 mannequin 12 months. With the usual SL63 already costing $184,150 earlier than choices, count on a beginning value of effectively previous the $200k mark. The not too long ago redesigned GT coupe will get a PHEV variant too, doubtlessly with much more energy than the SL.
