Overview
- Mercedes‑AMG officially unveiled the CLE 646 Spezialanfertigung on Thursday, September 10, 2026, as the second car in its Mythos Series and a handbuilt, low‑volume halo model.
- The car uses a heavily reworked 4.0‑litre M177 Evo twin‑turbo V8 with a flat‑plane crank that produces 475 kW (646 PS) and 850 Nm and is paired with a nine‑speed automatic driving the rear wheels through an electronically controlled limited‑slip differential.
- Mercedes quotes performance of 0–100 km/h in 3.9 seconds and a 310 km/h top speed, and the CLE 646 sheds about 170 kg versus the CLE 53 to reach a kerb weight near 1,895 kg through extensive carbon‑fibre work and deletion of interior equipment.
- The car is built by hand in Affalterbach, limited to 250 total examples with only 30 road‑legal units, equipped with track hardware such as four‑way KW coilovers, large ceramic brakes, an Akrapovič titanium exhaust and adjustable aero claiming up to 250 kg of downforce.
- Mercedes‑AMG says most allocations are already committed, Mercedes‑Benz Australia has no plans to offer the model there, and the CLE 646 is meant as a collectible statement that precedes a more conventional V8‑powered CLE63 now reported to be in development.
