Mercedes-AMG CLE 646 Special Debuts with 646 PS V8

Mercedes-AMG CLE 646 Spezialanfertigung: Defining the 30-Unit V8 Special

The Mercedes-AMG CLE 646 Spezialanfertigung is an ultra-exclusive, limited-production grand tourer developed by Mercedes-AMG as the second model in its Mythos series, following the 250-unit Mercedes-AMG PureSpeed introduced in December 2024. Based on the Mercedes-AMG CLE 53 4Matic+ Coupé, which launched in Malaysia in September 2025 at RM723,000, this special edition is a high-performance variant powered by a 4.0-litre biturbo V8 engine producing 646 PS (637 hp or 475 kW). The name "Spezialanfertigung" translates from German to "custom made," signalling its bespoke nature. With only 30 units offered globally, it serves as both an extreme performance flagship and an early preview of a potential CLE facelift, targeting collectors and driving enthusiasts who demand exclusivity and track-oriented capability.

The Mercedes-AMG CLE 646 Spezialanfertigung is a 30-unit limited-production coupé with a 646 PS biturbo V8, representing the peak of the CLE model line.

Key Facts

This section provides the definitive specification summary for the Mercedes-AMG CLE 646 Spezialanfertigung, with data drawn directly from the official debut announcement.

Only 30 examples of the Mercedes-AMG CLE 646 Spezialanfertigung will be produced worldwide, making it rarer than the 250-unit PureSpeed.

What Powertrain Does the Mercedes-AMG CLE 646 Use?

The Mercedes-AMG CLE 646 is powered by the M177 Evo, an enhanced version of the 4.0-litre biturbo V8 engine that powered true AMG models over the past decade, featuring a flat-plane crankshaft and three separate cooling circuits. This engine delivers 646 PS (637 hp or 475 kW) from 6,000 to 6,250 rpm and 850 Nm of torque from 2,500 to 4,500 rpm, making it significantly more powerful than the CLE53's 449 PS (443 hp or 330 kW) and 600 Nm output.

The exhaust system is developed in cooperation with Akrapovic, using significant amounts of titanium to reduce weight. A 48-volt mild-hybrid system with an integrated starter generator provides an additional 23 PS (23 hp or 17 kW) and 205 Nm, supporting recuperation, load point shifting, cruising, and smoother start-stop operation. The previous non-Evo M177 variant used a cross-plane crankshaft and delivered 639 PS (630 hp or 470 kW) in the GT63S 4-Door Coupé.

"Different from the CLE53 is the drivetrain, as the CLE 646 ditches the all-wheel drive system to send drive exclusively to the rear wheels via a nine-speed AMG Speedshift TCT 9G automatic transmission."

Paul Tan's Automotive News, September 2026

The M177 Evo in the CLE 646 produces 646 PS and 850 Nm, a substantial increase over the CLE53's 449 PS and 600 Nm.

How Has the Chassis Been Upgraded for Track Use?

Mercedes-AMG has equipped the CLE 646 with steel coilover suspension developed together with KW Automotive, featuring four-way adjustable dampers with independently configurable low-speed and high-speed rebound and compression settings. This is complemented by an AMG Ceramic High-Performance Composite Braking System with 420 mm front rotors and six-piston fixed callipers, plus 360 mm rear rotors with single-piston floating callipers.

The body structure receives additional reinforcements in various locations and an integrated rollover bar, which improves rigidity but also results in the deletion of the rear seats and acoustic insulation materials. Ride height is reduced by 22 mm at the front and 16 mm at the rear compared to the CLE53. The car sits on 20-inch forged wheels with staggered tyres (305/30R20 front, 335/30R20 rear), developed from technology originally created for the Mercedes-AMG One hypercar and exclusive to the CLE 646.

The nine-stage AMG Traction Control system allows drivers to select the amount of wheel slip permitted, while the carbon-fibre components include vented front fenders, a front apron with large cooling intakes, an adjustable diffuser, side sills, bonnet scoop, roof, and rear bumper with integrated diffuser.

The CLE 646 features KW Automotive coilover suspension with four-way adjustable dampers, ceramic brakes, and carbon-ceramic components developed from the Mercedes-AMG One.

What Are the Key Exterior and Interior Design Changes?

The Mercedes-AMG CLE 646 introduces new tristar-themed exterior lights for the CLE line, which could be introduced to more conventional variants as part of a future facelift. The body is 60 mm wider front and rear than a CLE53, achieved through an extensively modified shell that increases structural rigidity. The front section is finished in Mojave Silver Magno, while from the B-pillar rearwards is Obsidian Black Magno.

Interior changes include carbon-fibre door panels, ultra-lightweight bucket seats, and a revised AMG Performance steering wheel with fewer controls because of fewer drive modes and assistance systems, including the deletion of Parktronic. Six-point harnesses are optional extras. The boot lid is reinforced with trapezoidal supports for the manually adjustable rear wing, and the rear side windows and rear window are made from polycarbonate to save weight. A lighter 12-volt starter battery is also used.

AMG crests on the driver's and passenger's doors and a 'V8' badge on the fender vents are notable visual cues on this special edition.

The CLE 646 features a two-tone Mojave Silver Magno and Obsidian Black Magno exterior, with carbon-fibre body panels and tristar-themed headlights.

Who Is This For in Malaysia?

The Mercedes-AMG CLE 646 Spezialanfertigung is aimed at Malaysian collectors and high-net-worth driving enthusiasts who seek extreme rarity and track-focused performance, not everyday practicality. Given the CLE53 launched in Malaysia at RM723,000 in September 2025, the CLE 646 will likely command a significant premium, potentially exceeding RM1.5 million with Malaysian import duties and taxes. This is not a vehicle for daily commuting in Kuala Lumpur traffic; it is a weekend toy and garage queen for those who already own practical daily drivers.

Malaysian buyers should note the car's rear-wheel-drive layout and 310 km/h top speed are far beyond legal road limits in Malaysia, so its value lies in occasional track use at circuits like Sepang International Circuit and in collection appreciation. The deleted rear seats and acoustic insulation make it impractical for carrying passengers or luggage. The use of polycarbonate windows and lightweight materials also suits Malaysia's tropical climate, though owners should ensure proper shaded or indoor parking to protect the matte Magno paint finishes from prolonged sun exposure.

For Malaysian buyers, the CLE 646 is a collector-grade investment vehicle for track days and display, not a daily driver, with pricing expected well above the CLE53's RM723,000 local launch price.

Common Questions

When will the Mercedes-AMG CLE 646 be available in Malaysia?

No Malaysian launch date has been announced. Given the global production limit of 30 units and the prior CLE53 launch in Malaysia in September 2025, local availability will likely be extremely limited, possibly allocated by invitation only through Mercedes-Benz Malaysia. Interested buyers should contact their local dealer for allocation details.

How does the CLE 646 differ from the CLE53 in Malaysia?

The CLE 646 uses a 4.0-litre biturbo V8 producing 646 PS, whereas the CLE53 sold in Malaysia uses a 3.0-litre inline-six turbo producing 449 PS. The CLE 646 is also rear-wheel drive, lighter, wider by 60 mm, and features track-focused suspension, ceramic brakes, and a fully carbon-fibre body kit.

Is the CLE 646 a road-legal car for Malaysian roads?

Yes, the CLE 646 is expected to be road-legal if imported and registered in Malaysia, subject to JPJ approval and local import regulations. However, its 310 km/h top speed and track-oriented suspension make it more suited to closed-circuit use at Sepang International Circuit than everyday Malaysian road conditions.

The CLE 646's 30-unit global production run and expected high pricing position it as a collector's item rather than a volume model in Malaysia.
