Mercedes-Benz’s new E Efficiency tree has born its first vital fruit: the 2023 Mercedes-AMG GT 63 S E Efficiency. We famous beforehand that Benz’s teaser of a brand new, electrified AMG GT mannequin bore a putting resemblance to the 63 S. Properly, because it seems, that is precisely what the parents in Affalterbach had in thoughts.
As the primary efficiency mannequin powered by AMG’s new V8 hybrid powertrain, the GT 63 S E Efficiency will be forgiven for taking some huge swings. How huge? Attempt 831 horsepower and greater than (their phrases, not ours) 1,033 pound-feet of torque.
The dual-turbocharged, 4.0-liter V8 is, at its most basic degree, not all that dissimilar from the one present in lots of the firm’s extra “pedestrian” AMG fashions. However while you pair it to a 201-horsepower electrical motor mounted on to the rear axle, issues get a bit extra spicy. Borrowing tech from the AMG Undertaking One and its latest line of mild-hybrid gasoline engines, the brand new E Efficiency powertrain represents a big evolution of the AMG system. This new modular powertrain pairs the rear-mounted electrical drive unit to a turbocharged gasoline engine. The electrical motor drives the rear axle straight, however energy will be despatched to the entrance axle (primarily the identical method it’s transferred from the gasoline engine to the rear, simply in reverse), because of AMG’s superior all-wheel drive system.
“With the brand new Mercedes-AMG GT 63 S E Efficiency, we’re transporting our model DNA into an electrified future,” stated AMG boss Philipp Schiemer. “In doing so, we’re following our personal technical path, which is what has all the time made AMG so particular and fascinating.”
Simply how particular are we speaking right here? AMG says the GT 63 S E Efficiency will hit 60 mph in simply 2.9 seconds and 125 mph in underneath 10. High pace? 197 mph. Its electrical car credentials are a bit extra modest, nevertheless. Regardless of being a plug-in mannequin (the charging port is seen within the rear bumper), the E Efficiency makes do with a 6.1 kWh battery good for under about seven (sure, 7) miles of all-electric vary.
“Developed solely in Affalterbach, the efficiency hybrid gives a captivating degree of driving dynamics and rightly bears our new know-how label E Efficiency. With this new idea, we’re additionally opening as much as new goal teams who will expertise Mercedes-AMG because the efficiency luxurious model of the twenty first century.”
Whereas the V8 up entrance is in any other case typical, it does incorporate an electrical turbocharger. Mercedes has dabbled in electrical boosting with its 48-volt gentle hybrid powertrains, however this represents a reasonably vital evolution of the tech. At its core, it is nonetheless an exhaust-powered turbine, however at decrease engine speeds and throttle openings, it will likely be juiced by electrical energy from the E Efficiency hybrid’s battery, spooling it immediately and successfully eliminating any potential turbo lag. On this capability, it eliminates the necessity for added (or extra advanced) turbochargers to clean out energy supply at totally different engine speeds.
Out again, the drive unit integrates the mechanical differential (related to the V8 by an old school mechanical prop shaft) with the electrical drive unit, which is fed straight by the rear-mounted battery pack. Mercedes says the 63 S E Efficiency’s rear drive unit makes use of a two-speed transmission (to not be confused with the traditional 9-speed multi-clutch unit paired to the V8 up entrance) that shifts at roughly 87 mph, which corresponds to the electrical motor’s most pace of 13,500 RPM.
Whereas this mannequin is clearly set as much as be a efficiency automotive first, the underlying tech is successfully application-agnostic. Dial again the size of the engine and add some battery capability, and the identical modular system might ship considerably extra all-electric vary, making a superb basis for a extra luxurious (and frugal) premium expertise. You recognize, such as you would possibly anticipate from an S-Class.
And since it is a Mercedes, each mechanical bit is paired with six or seven microprocessors (no, we did not truly do the mathematics). The drive modes (Mercedes refers to it as its “Dynamic Choose” system) have been formed with the 63 S E Efficiency’s hybrid powertrain in thoughts. The selector features a full EV mode (vital in Europe) together with many of the traditional suspects.
In a nod to those that want finer management over every efficiency system, Mercedes has a separate setting only for brake regen. Degree zero is designed to really feel identical to a bog-standard inner combustion automotive and degree three permits for one-pedal driving; ranges one and two cut up the distinction. Mercedes notes that choosing the “Race” mode from dynamic choose routinely adjusts the regen to the equal of degree one “to permit essentially the most reproducible car conduct potential on the limits.”
All the figures right here had been derived from the European-spec mannequin. Mercedes says it’ll launch U.S. specs (together with curb weight, which we’re desperate to see) and pricing nearer to the AMG GT 63 S E Efficiency’s official on-sale date, which is predicted to be a while subsequent yr.
