Bad news first: the The V8 era in Mercedes-AMG is officially over. The thunderous 4.0-liter M177 twin-turbo eight-cylinder that is has powered all muscle cars in the AMG 63 series since 2015 is not long for this land. Here’s what will replace it: a Formula 1-inspired hybrid drivetrain getting married the most powerful in the world production car four cylinders (with an electrically boosted turbocharger, no less) a 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 sport the all-new transmission, that means a maximum of 671 horsepower and a whopping 752 lb-ft of torque. Yes, this will help us overcome the loss of the V8.
The all-new C63 marks a whole new era at AMG, a company that has spent nearly half a century transforming Mercedes V8s into noisy tire shredders. The extremely elaborate transmission of the ’24 C63 starts with an impressive foundation: the M139L 2.0-liter turbocharged four-cylinder, first developed by AMG for Mercedes-AMG A45, CLA45 and GLA45. In those models, the tiny turbo engine was the most powerful four-cylinder ever fitted to a production vehicle, delivering 416hp and 369Nm of torque. Now, thanks to an ingenious electrical turbocharger configuration, this engine delivers even more power: 469 hp at 6,750 rpm and 402 lb-ft from 5,000 to 5,500 rpm. This means that the 1,991cc M139L breaks its record as the most powerful production four-cylinder in history, delivering a hair of less than 235hp per liter of displacement or, in other words, a touch of more than 117hp for cylinder.
That power is provided by a recently expanded turbo with electric assistance, meaning the turbo can build up electrical energy before exhaust pressure takes over, helping to eliminate lag and create a sharper response. This is the first application on a production car of this electric turbocharger technology, which derives directly from today’s Formula 1 hybrid drivetrains and takes advantage of the new C63’s 400-volt electric architecture.
Of course, the huge new turbocharger isn’t the only example of electric horsepower enhancement. The new C63 has a 201 hp, 236 lb-ft electric motor that drives the rear axle through a two-speed gearbox, assisting the gasoline engine during heavy acceleration. With Performance 4Matic + AMG all-wheel drive with Drift Mode, the C63 delivers a maximum of 671PS and 752Nm of torque on all four wheels, with the petrol engine driving the nine-speed AMG automatic transmission with wet clutch. oil in a torque converter position for faster acceleration and gear changes.
Mercedes says the new muscle sedan can accelerate from zero to 60 mph in 3.3 seconds, and the power of both the longitudinally-mounted gas engine and the rear-axle electric motor can be shifted to the front axle as the rear wheels spin. The two-speed gearbox that transmits the torque of the rear axle motor changes automatically according to the speed and load; the lower of the two ratios is good up to 87 mph. The engine delivers 94hp continuously, with all 201hp available in 10-second bursts.
The 400-volt, 6.1-kWh, 196-pound, liquid-cooled lithium-ion battery that drives the The axle motor rests on top of the rear axle for optimal weight distribution. While the new C63 is technically a plug-in hybrid and can reach speeds of up to 81 mph on electric power alone, Mercedes-AMG was quick to point out in a press release that “the battery is designed for rapid power delivery and absorption rather than the longest range possible.
The new C63 bears a vague resemblance to the lesser C-class sedans, but benefits from plenty of AMG-specific tweaks. The wheelbase has been lengthened by 0.4 inches, with the front body lengthened by 2.2 inches. Overall, the new C63 is a whopping three inches wider on the front fenders and 3.3 inches longer from nose to tail. The new hybrid muscle sedan travels on standard 19-inch staggered wheels and tires, with 20 years optional.
The compact high-performance sedan has standard rear steering, which makes the car more agile in tight corners and more stable during high-speed highway maneuvers, 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 modifies the transmission output, steering, suspension and sound.
Because yes, this is a four-cylinder hybrid, and that means AMG has had to resort to increased transmission noises to replace the pounding rumble of that old twin-turbo V8. A single speaker in the front bumper and a two-speaker soundbar in the rear make warning noises when the C63 is driving in pure EV mode; traveling with internal combustion power, the system picks up the sound from a pressure sensor in the exhaust system and “enriches[es] further before it is emitted inside via the entertainment audio system, thus making the AMG characteristic sound experience possible. The C63 has iron rotor brakes with six-piston calipers at the front and single-piston calipers at the rear, as well as four levels of regenerative braking ranging from nearly zero regen to driving to a full pedal.
Inside, it has screens and screens and ambient lighting and glossy finishes and screens and screens.
Mercedes-AMG has not yet revealed when the new C63 SE Performance will go on sale, nor has the automaker revealed the price. We will certainly learn all this information before Mercedes invites journalists to drive this vehicle on their own.
We have known for some time that Mercedes-AMG would be heading in this direction. Big V8s are going out of style (even though the 4.0-liter AMG V8 was not That great in the grand scheme of things). Some reducers will cry and grind for it. But if the alternative is the shit – a C-Class with more power and torque than ever, with pure plug-in EV driving capability and F1-inspired turbo and hybrid technology – it’s kind of foolish to cry over what’s gone. to the past.
