New 2021 Mercedes-AMG C43 spied in estate form

 Hot middleweight Mercedes-AMG C43 has been spotted testing once more – this time as an estate

Our spy photographers have spotted another Mercedes-AMG C43 prototype but in estate form for the very first time. The brand’s latest performance-focussed compact executive car is expected to be revealed this Autumn, providing new competition for the BMW M340i xDrive.

Compared with regular versions of the next Mercedes C-Class, AMG variants like this C43 will bear a much sportier look. This mule features a more aggressive body kit with a lower front splitter, broader side skirts and a new quad-exit exhaust system, housed in a large rear diffuser. The radiator grille is also likely to receive a redesign, while the production model should feature a unique set of AMG alloy wheels.

This new estate also has a larger spoiler mounted to its tailgate, while the saloon makes do with a duck-tail unit mounted to its boot-lid. Our previously spied mule featured a pair of makeshift canards mounted to its front bumper, which could eventually be offered on the production car as an optional extra.

Mercedes has already confirmed that the next-generation C-Class will have a completely redesigned interior, with digital instrumentation as standard and a large infotainment screen stretching from the bottom of the centre console to the top of the dashboard. However, as this is an AMG model, the cabin will also get sports seats, aluminium pedals and a sports steering wheel.

Like the standard saloon, the new Mercedes-AMG C43 will be based on an updated version of the outgoing C-Class’s rear-wheel drive MRA platform. As with the rest of the brand’s AMG 43 line-up, we also expect it’ll be powered by a turbocharged 3.0-litre straight-six petrol engine that develops around 400bhp.

The new AMG C43 will come with a range of chassis upgrades, including adaptive dampers, uprated anti-roll bars and a set of enormous drilled discs with six-piston calipers – as shown behind the wheels of both our spied test mules.
