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.”

  • Arthur Dailey I do miss the exuberant exterior colours of the 1950's domestics, including the two-tone paint jobs. And 'there is no face like chrome'.
  • Bunkie From the “you can’t make this stuff up” department, the headline of the ad that occupied the screen right next to the picture of this Maserati read “Blunder #11”It’s an in joke in my household as my wife keeps getting offers from one of her financial institutions to lease a Maserati, an offer that is, consistently, declined.
  • Theflyersfan Interest rates going sky high should knock out the next group of people on the fence waiting to buy. I haven't looked, but I'm betting 2.9 and 3.9% on longer 60+ month loans are either gone or almost impossible to qualify for. I'm starting to get "turn down the thermostat and put on a sweater" vibes here. And if you're an American in Iran, get out. We don't need a sequel to Argo.
  • Theflyersfan @Matthew Guy: You might have jumped the gun on this one a little bit. Chevy's website doesn't have a build/config page up yet, nor does KBB or Edmunds. All we have to go on is what Chevy has leaked out to us without seeing the finished product. And I don't see prices on options and each model just yet, just somewhat "around this amount." But all that being said, if I was in the market for a pickup, and saying that I close on a new home later this week (locked in rates before interest rates really went crazy), the MX-5 might need a stablemate. And the "regular" trucks that everyone thinks of have just gotten too large, too over-styled (except for the Ram), and way too expensive. So this size truck seems to hit the sweet spot of people, cargo, and ease of driving/parking needs. So, I'd probably go mid-range with something like the Z71 trim level. I'm guessing it'll be in the mid-30's with enough tech to keep everything connected, reasonable enough fuel economy, and comfort for a road trip. There are some great offroad trails all around Kentucky, and that would have me interested in something like a ZR2, but without knowing exact cost, not sure about that one.But in this class, the Tacoma and Ranger are up there in years and Nissan, while putting in a different engine and transmission, pretty much tidied up the same old bones and is selling it as all new...(Z car...cough...cough). I'd still have to try the Frontier vs. Colorado to make up my mind.
  • Bkojote I go off-roading quite a bit (nothing extreme, just some fun scenic trails) and everyone in our group with a Colorado has basically given up or switched to a Toyota/Jeep after dealing with constant issues and $$$ in repairs.The best trim for the Colorado is something on-road biased. These trucks are good for towing toys or some light duty stuff but a burly off road trim on this is silly as the 4WD system can't handle it. While I believe they fixed the major design flaws of the prior generation (an easily-damaged oil pan and poorly positioned shocks that hang precariously low), the clutch-based 4WD system is notorious for failing on moderate trails- look no further than the recent C&D "Trail Boss" review.
