Bad news first: The The V8 era at Mercedes-AMG is officially over. The M177 Thunder 4.0-liter twin-turbo eight-cylinder that’s it has powered every muscle car in the 2015 AMG 63 series It is do not long for this earth. Here’s what will replace it: a Formula 1-inspired hybrid drivetrain that gets married the strongest in the world machine production four cylinders (with an electrically powered turbocharger, no less) to an electric motor that drives the rear axle through a two-speed gearbox. In the 2024 Mercedes-AMG C63 SE Performance, the first AMG to have the new power unit, which means a maximum of 671 hp and an amazing 752 lb-ft of torque. Yes, that will help us get over the loss of the V8.

The new C63 marks a whole new era at AMG, a company that has spent nearly half a century turning Mercedes V8s into tire shredders. The highly elaborate powertrain of the ’24 C63 starts from an impressive base: the M139L 2.0 liter turbo four-cylinder, first developed by AMG for Mercedes-AMG A45, CLA45 and GLA45. In those models, the small turbo engine was the most powerful four-cylinder ever fitted to a production vehicle, producing 416 hp and 369 lb-ft of torque. Now, thanks to an ingenious electric Turbocharged configuration, this engine puts out even more power: 469 hp at 6,750 rpm and 402 lb-ft from 5,000 to 5,500 rpm. That means the 1,991cc M139L breaks its own record as the most powerful production four-cylinder in history, pumping out just a hair less than 235bhp per liter of displacement – ​​or put another way, a touch over 117bhp per cylinder.

That output comes thanks to a newly enlarged turbo with electric assist, meaning the turbo can feed itself with electricity before exhaust pressure takes over, helping to eliminate lag and create sharper response. This is the first production car application of this electric turbocharger technology, which comes directly from today’s Formula 1 hybrid powertrains and takes advantage of the new C63’s 400-volt electric architecture.

Of course, the huge new turbocharger isn’t the only example of an increase in electric power. The new C63 has a 201 hp, 236 lb-ft electric motor that drives the rear axle through a two-speed gearbox, assisting the gas engine during hard acceleration. With AMG Performance 4Matic+ all-wheel drive with Drift mode, the C63 delivers a maximum of 671 hp and 752 lb-ft of torque to all four wheels, with the petrol engine driven through AMG’s nine-speed wet-clutch automatic transmission. of a torque converter for faster acceleration and gear changes.

Mercedes says the new muscle sedan can sprint from zero to 60 mph in 3.3 seconds, and power from both the longitudinally mounted gasoline engine and rear-axle electric motor can be transferred to the front axle when the rear wheels glide. The two-speed gearbox that transmits torque to the rear axle motor automatically shifts depending on speed and load; the lower of the two ratios is good for up to 87 mph. The engine delivers 94 hp continuously, with the full 201 hp available in 10-second bursts.

400-volt, 6.1 kWh, 196 lb, liquid-cooled lithium-ion battery drives the axle motor rests above the rear axle for optimal weight distribution. While the new C63 is technically a plug-in hybrid and can reach speeds of up to 131 km/h on electric power alone, Mercedes-AMG was quick to point out in a press release that “the battery it is designed for fast power delivery and power consumption. rather than the longest possible range.”

The new C63 bears a passing resemblance to the smaller C-Class sedans, but benefits from a host of AMG-specific tweaks. The wheelbase was stretched by 0.4 inches and the front bodywork was extended by 2.2 inches. Overall, the new C63 is three inches wider at the front fenders and 3.3 inches longer from nose to tail. The new hybrid muscle sedan is equipped with standard 19-inch wheels and tires, with 20s optional.

The compact performance sedan has standard rear-wheel steering, which makes the car more agile in tight turns and more stable during high-speed maneuvers on the highway, and rides on Mercedes AMG Ride Control adaptive suspension with steel springs. The new C63 offers eight driving modes: Electric, Comfort, Battery Hold, Sport, Sport+, Race, Slippery and Individual, each of which alters transmission power, steering, suspension and sound.

Because, yes, this is a four-cylinder hybrid, and that means AMG had to resort to increased powertrain noise to replace the clatter of that old twin-turbo V8. A single speaker in the front bumper and a dual-speaker soundbar in the rear emit warning sounds when the C63 is driving in pure EV mode; when running under internal combustion power, the system takes sound from a pressure sensor in the exhaust system and “enriches[es] further before being emitted inside via the entertainment sound system, thus making it possible to experience the characteristic AMG sound.” The C63 has iron rotor brakes with six-piston calipers up front and single-piston calipers in the rear, plus four levels of regenerative braking, from near-zero regen to full one-pedal driving.

Mercedes-AMG has yet to reveal when the new C63 SE Performance will go on sale, nor has the automaker revealed pricing. We will surely find out all this information before Mercedes invites journalists to drive this vehicle for themselves.

We’ve known for some time that Mercedes-AMG would be heading in this direction. Big V8s are going out of style (even if the 4.0 liter AMG V8 wasn’t that big in the grand scheme of things). Some gearheads will whine and whine about it. But if the alternative is stuff like this – a C-Class with more horsepower and torque than ever before, pure plug-in EV driving capability and F1-inspired turbo and hybrid technology – it feels a little silly to cry about what happened. last.
