Limited-Edition 2027 Mercedes-AMG CLE 646 Spezialanfertigung Debuts for Collectors

Quebec collectors who track AMG’s rarest builds already know the name Mythos Series. The 2027 Mercedes-AMG CLE 646 Spezialanfertigung is the second car in that series, and it was sold out before its own world premiere.

This is not a trim level or an options package. It is a hand-built, road-legal coupe built around one goal: maximum driving dynamics on both roads and closed circuits.

What’s Confirmed So Far

The CLE 646 Spezialanfertigung is built on the CLE 53 platform but reworked into a distinct vehicle. Each unit is hand-assembled at AMG headquarters in Affalterbach, continuing a manufactory tradition that includes cars like the AMG 300 CE 6.0 “The Hammer.”

Only 30 examples will be produced worldwide. That scarcity, combined with a road-legal chassis tuned for racetrack use, is what separates this car from a standard CLE Coupe wearing an AMG badge.

The engineering brief was not a list of upgrades bolted onto an existing car. AMG’s team treated the CLE 646 as a full performance system: a reworked drivetrain, a purpose-tuned chassis, extensive lightweight construction, and modified bodywork, all developed together rather than layered on afterward.

Specifications That Define This Build

The numbers below are what set this Mythos model apart from anything else wearing a CLE badge.

The V8’s integrated starter generator adds 23 hp and 151 lb-ft to support the main engine, while the flat-plane crankshaft design sharpens throttle response and revving character. Weight dropped by roughly 375 lbs (170 kg) versus the donor CLE, through measures that include a simplified interior and extensive carbon fibre use.

The most significant mechanical change is the drivetrain itself. AMG removed the standard CLE’s 4MATIC+ all-wheel-drive system entirely, sending power to the rear wheels only. An electronically controlled limited-slip rear differential manages torque between the rear wheels, improving traction and stability, and under the right conditions supporting controlled drifting.

What Matters for Shoppers Evaluating This Car

This is not a car built for daily comfort, and Mercedes-AMG is not pretending otherwise. The rear seats, sound system, and PARKTRONIC parking assistant have all been removed to save weight and sharpen the driving experience. Six-point harnesses are available through the optional Performance Package.

What stays is purpose-built: racing bucket seats with pronounced lateral support, a roll bar, carbon fibre door panels, and an AMG Performance steering wheel with fewer controls than a standard CLE, since many of the drive modes and assistance systems it once managed no longer exist on this car.

The chassis gets coilover suspension front and rear, an AMG Ceramic High-Performance Composite Braking System, and AMG TRACTION CONTROL that lets a driver preselect wheel slip across nine stages with stability control switched off. The wide-body treatment, wider front and rear tracks, and 305/30 ZR 20 front and 335/30 ZR 20 rear tires give the car a planted stance that matches its intent.

For a buyer weighing this against a standard AMG CLE, the honest answer is that they are not really the same conversation. The 646 Spezialanfertigung trades rear seats, a full sound system, and all-wheel drive for a lighter, rear-driven car built to be driven hard. It rewards a collector or AMG loyalist who wants rarity and track character over daily usability, not someone shopping for a comfortable weekend coupe.

A two-seat, track-tuned layout by design narrows who this car is for. It fits a garage already built around special editions and statement vehicles, alongside other cars chosen for what they represent rather than for everyday practicality.

Next Steps for Quebec Collectors

With production limited to 30 units globally and the car already sold out ahead of its premiere, allocation and ownership interest are the real conversation for Quebec buyers right now, not showroom timing. Anyone tracking the Mythos Series should expect updates on market availability and resale interest to move quickly given the scale of this build.

The Mercedes-AMG CLE 646 Spezialanfertigung is a 30-unit, rear-wheel-drive Mythos Series coupe built around a 637-hp V8 biturbo engine, a lightened chassis, and a purpose-built cockpit stripped for driving dynamics rather than comfort.
