Mercedes-AMG C 63 Appears as a 671hp Plug-in Hybrid for 2024

mercedes amg c 63 appears as a 671hp plug in hybrid for 2024

Affalterbach rather backed itself into a corner with the C 63 – at least in terms of its powerplant. For ages, the octopot racket was a key part of the package, meaning any replacement featuring less than eight cylinders would need to blow the doors off itself in order to avoid derisive looks from the cognoscenti

Leave it to AMG to tackle the thorny issue of four-bangers head-on by delivering one which, by itself, produces a scarcely believable 469 horsepower – then add an electric motor on the rear axle which pushes total output to nearly 700 horses.

Its full name is actually the Mercedes-AMG C 63 S E PERFORMANCE, a typically precise German moniker that denotes this thing as a plug-in hybrid. Under the hood is an AMG 2.0L four-cylinder turbo, one which tag teams a so-called “permanently-excited” synchronous electric motor on the car’s rear axle. We wish all electric motors were permanently excited, but we digress. This partnership is good for a system output of 671 horsepower and maximum system torque of 752 lb-ft of twist. Merc says 60 mph is yours in 3.3 seconds. A 9-speed transmission, in which a wet start-off clutch replaces the torque converter, handles shifting duties.

Well, some shifting duties. Engineers go on to explain the electric motor is integrated with an electrically shifted two-speed gearbox which upshifts at 87 mph. This notation will take some time for your author to comprehend, particularly the knowledge  An electronically controlled limited-slip rear diff sorts out traction in the aft quarters, which is also weighted with a 6.1 kWh battery above the rear axle. For the first time in a C 63, the fully variable AMG Performance 4MATIC+ all-wheel drive transfers power to the road at all four corners, packing a Drift Mode for even more driving shenanigans. Adding to the levity is active rear-axle steering, 2.5 degrees opposite to the fronts under 62 mph and 0.7 degrees in concert with the fronts above that speed, fitted as standard kit and touted as a unique feature in this segment. 

Though the figure of 671 will be breathlessly parroted by many, we are keen to learn more about the allocation of all these horses. Why? Buried deep in the C 63 bumf is the caveat that “the high-performance battery offers a capacity of 6.1 kWh, a continuous output of 94 hp and a peak output of 201 hp for ten seconds.”

Knowing that, it seems drivers will need to thumb a manettino-style button in order to always have access to 671 ponies or stick the car in a particular one of its many driving modes. Will there be a refractory period (as there is in many cars with such a system) of 10 or 15 seconds as a cool down? We will find you these answers – preferably behind the wheel during a First Drive next year.

Elsewhere, the design of the new C 63 S differs from the Mercedes-Benz C-Class in its more muscular proportions, with a front end two inches longer and wider fenders. Matching side skirts, unique fascias, staggered tires, and the typical AMG addenda let everyone know this ain’t a (god forbid) workaday C Class. Improvements to the MBUX infotainment system, including some specific hybrid power displays, are also part of the deal.

While AMG didn’t detail a specific on-sale date for America, its designation as a 2024 model suggests it’ll show up in dealers sometime in the next calendar year.

    I saw my first IS500 out in the wild today (a dark-grey-on-black example) and it struck me that it was much more AMG-like than this product. (Great-looking and -sounding car.)

    Lease fodder that in 6 years will be on the 3rd owner in a poverty bound aspirational individual's backyard in a sub par neighborhood sinking into the dirt. The lending bank will not even want to repossess and take possession of this boat anchor of a toxic waste dump. This proves that EVs are not even close to being ready for prime time (let's not even talk about electrical infrastructure). EVs only exist in wildly expensive virtue signaling status-mobiles. FAIL! I know this is a Hybrid, but it's a Merc., so it will quickly die after the warranty. Show me a practical EV for the masses and I'll listen. At this time, Hybrids are about the way to go for most needing basic transportation.

      I’m just going to point out the irony of a guy with your handle complaining about “wildly expensive status-mobiles.”

  • Kcflyer on one hand it at least wont have dirty intake valves like Honda's entire lineup of direct injection ice vehicles. on the other hand a CRV offers more room, more range, faster fueling and lower price, hmm
  • Tassos BTW I thought this silly thing was always called the "Wienermobile".
  • Tassos I have a first cousin with same first and last name as my own, 17 years my junior even tho he is the son of my father's older brother, who has a summer home in the same country I do, and has bought a local A3 5-door hatch kinds thing, quite old by now.Last year he told me the thing broke down and he had to do major major repairs, replace the whole engine and other stuff, and had to rent a car for two weeks in a touristy location, and amazingly he paid more for the rental ( Euro1,500, or $1,650-$1,700) than for all the repairs, which of course were not done at the dealer (I doubt there was a dealer there anyway)
  • Tassos VW's EV program losses have already been horrific, and with (guess, Caveman!) the Berlin-Brandenburg Gigafactory growing by leaps and bounds, the future was already quite grim for VW and the VW Group.THis shutdown will not be so temporary.The German Government may have to reach in its deep pockets, no matter how much it hates to spend $, and bail it out."too big to fail"?
  • Billccm I had a 1980 TC3 Horizon and that car was as reliable as the sun. Underappreciated for sure.
