Every fighter eventually gets asked to take the gloves off, and most sensibly decline. The Mercedes-AMG CLE 646 Spezialanfertigung is the one that said yes. Thirty of them exist, all sold before the official reveal, and every single design decision reads like a car deliberately choosing the harder, bare-knuckle version of itself over the padded, forgiving alternative sitting right next to it in the same showroom.
The Weigh-In
AMG built this car as a direct tribute to the AMG 300 CE 6.0 „Hammer“ of the 1980s, one of the most uncompromising cars Affalterbach has ever fielded, and the name alone tells you what kind of fight this is meant to be. The reworked 4.0-litre V8 biturbo, badged M177 EVO internally, gets a flat-plane crankshaft for sharper response and produces 475 kW (646 PS) with 850 Nm of torque between 2,500 and 4,500 rpm. An Akrapovič titanium exhaust sends the sound out completely unfiltered, the acoustic equivalent of skipping the walkout music and just starting the round early. Peak power lands at 6,000 rpm, well above where most rivals have already backed off in the name of comfort and emissions compliance.
Taking the Gloves Off
The genuinely bold call sits in the drivetrain. AMG pulled the standard 4MATIC+ all-wheel-drive system out entirely; every one of those 646 PS now reaches the road through the AMG SPEEDSHIFT TCT 9G torque-converter gearbox and a locking rear differential, with a nine-stage traction control system standing in as the only corner man left in the fighter’s camp. No second axle to bail anyone out. 0 to 100 km/h takes 3.9 seconds, 0 to 200 km/h takes 11.4 seconds, and the car keeps swinging to 310 km/h, entirely on the back wheels. Land the punch wrong and there’s genuinely nobody else in the ring left to absorb the mistake for you.
Cutting Weight for the Fight
Corner preparation here means stripping, not building. Sound insulation, the rear seats, comfort features and even the Parktronic parking sensors are gone, replaced by ultra-light racing shell seats, carbon door panels and a fixed roll bar. Combined with the missing all-wheel-drive hardware, that removes 170 kilograms from the car, for a DIN kerb weight of 1,895 kilograms. Tracks are widened by 60 millimetres front and rear, and the bodywork goes almost entirely carbon fibre: fenders with integrated vents, front and rear aprons, a rear diffuser, bonnet, roof, even the boot lid, with polycarbonate replacing heavier glass at the rear, one more small cut made in the name of a lighter, faster fighter.
A Corner Man Who Actually Knows the Sport
AMG brought in suspension specialist KW automotive to build a steel coilover setup with independently adjustable low- and high-speed compression and rebound damping, tunable click by click for whichever circuit it’s fighting on. A ceramic composite braking system with gold calipers and 420 mm front discs handles the deceleration, standing up to repeated hard stops the way a good corner man expects a fighter to absorb round after round without fading. An adjustable front diffuser switches between „Street“ and „Race“ modes for genuine venturi-effect downforce, and an adjustable carbon rear wing tunes the angle further; together the package produces over 250 kilograms of downforce at top speed, on a two-tone press car finished in Mojave Silver magno fading to Obsidian Black magno from the B-pillar back.
Verdict: Bare-Knuckle, Sold Out
No price was ever officially announced, because all 30 hand-built cars sold before anyone outside the factory got a look at the number, on reputation alone. That’s either a masterclass in marketing restraint or proof that a genuine audience still exists for the fight with no gloves, no all-wheel-drive corner man, and no comfort features whatsoever to hide behind. Whatever else changes about performance cars over the next decade, the CLE 646 goes into the record books having thrown every single punch bare-knuckle, and having found thirty willing buyers happy to bet on the outcome before the opening bell had even rung.
