Key points

• The CLE 646 Spezialanfertigung is the second model in Mercedes' ultra-luxury Mythos sub-brand, with all 30 planned units already sold.
• It features a 646-hp (475 kW) twin-turbocharged 4.0-liter flat-plane-crank V8 engine, producing 627 lb-ft of torque, sending power exclusively to the rear wheels.
• Performance includes 0-62 mph in 3.9 seconds, 0-124 mph in 11.4 seconds, and a top speed of 193 mph (310 km/h).
• Weight was reduced by approximately 170 kg (375 lbs) through carbon-fiber body panels, polycarbonate rear windows, and the removal of rear seats and acoustic insulation.

Background

This launch follows the 2022 introduction of the Mythos sub-brand, which debuted with the 250-unit PureSpeed SL. The CLE 646 represents a shift toward track-focused, rear-wheel-drive performance, contrasting with the brand's recent electric SUV previews and the earlier C63 coupe lineage.

How outlets are covering it

Motor1 emphasizes the car's exclusivity and V8 power, noting the sold-out status. Top Gear compares it to the Ford Mustang GTD, questioning why it isn't a 'Black Series' and noting its weight is heavier than a Porsche 911 GT3. Car and Driver highlights the return of the V8 sports coupe. NetCarShow provides detailed technical specs, confirming the 646 hp output and 850 Nm torque, and detailing the three-circuit cooling system and Akrapovič exhaust collaboration.

Why it matters

The CLE 646 signals Mercedes-AMG's continued commitment to high-performance internal combustion engines in a limited, collector-focused format, despite the industry's shift toward electrification. Its sold-out status underscores strong demand for exclusive, track-oriented V8 coupes.

What to watch

Mercedes-AMG has not announced a price or future production plans for the CLE 646. Top Gear expects to test the car soon to evaluate its performance against rivals like the Mustang GTD and Porsche 911 GT3 RS.
