On close inspection we can see that the new E-Class coupe will do without a B-pillar, and will likely feature retractable rear side windows.
The interior of the coupe is largely shared with the sedan, although this prototype features a gorgeous new circular vent design. This coupe also features analogue dials, but we expect high-end versions to feature a fully digital instrument cluster.
Unlike the current E-Class coupe and convertible, which is based on the C-Class platform, the new two-door E-Class models will be fully fledged members of the family. That means that they will inevitably spawn high-performance AMG variants, something that the current two-door models have lacked.
A leak last month indicated the new E63 sedan will be fitted with the most powerful variants yet of AMG's 4.0-litre twin-turbo V8 - which already serves in the C63 triplets and GT supercar. In the base E63 sedan, the V8 will produce 420kW/750Nm, while the E63 S will have 450kW/850Nm against its name.
The rest of the E-Class coupe's drivetrain lineup is likely to mirror what's available in the sedan. Petrol options in the four-door include the 135kW/300Nm E200 four-cylinder and the 245kW/480Nm six-cylinder E400, while turbo-diesel choices include the 143kW/400Nm E220d and 190kW/620Nm E350d.
The new coupe will likely debut at the end of 2016 or the beginning of 2017, with Australian sales kicking off some time in 2017.
