Mercedes-AMG’s yet-unnamed four-door coupe will spark a new war with its arrival in late 2018 in the hyper-saloon segment. Our spies spotted a pair of prototypes being tested in cold-weather conditions, with the cars still being covered under a light camouflage wrap.

The first dedicated four-door model from AMG is planning to offer a series of new, performance-focused plug-in hybrid powertrains under the EQ brand, producing up to 805hp. The colossal power figure will be combined with a 31-mile driving range on electric power alone according to the latest reports.


This will not only position it directly against the Porsche Panamera Turbo S E-Hybrid, but it will also make it the most powerful saloon on the market. The four-door AMG will feature wider tracks compared to the current E63 AMG but it will sit closer to the ground and of course have a lower and unique roofline for that coupe-like vibe.

Mercedes-AMG’s upcoming Panamera rival will be initially launched with the same 604 hp 4.0-liter twin-turbo V8 engine that the E63 is using, paired to a nine-speed automatic gearbox and the configurable all-wheel drive system.

The latest reports talk about the new Mercedes AMG making a possible debut at the Geneva Motor Show this March, with sales to begin later in 2018 and the plug-in hybrid versions to arrive in 2019.
