2017 Geneva Motor Show: Mercedes-AMG GT Concept revealed

MERCEDES-Benz has teased the Mercedes-AMG Concept – a four-door Porsche Panamera-fighting version of its sleek performance coupe – ahead of its reveal at this week's Geneva Motor Show.

While much of the styling is familiar, what's big news about this teaser for what will become the third member of the GT family is the introduction of "EQ Power" – a 450kW-plus kinetic energy recovery system-equipped hybrid engine that taps on the carmaker's extensive Formula One experience.

The EQ Power logo is inscribed on what looks like a camera-based system that replaces traditional wing mirrors. It might also be little more than a trick of the light, but the concept also appears to feature active aerodynamics around the grille and front air intakes. Down the rear, a single exhaust shaped like a princess-cut diamond features prominently.

Little more is known about the concept ahead of its Geneva launch, but as a genuine rival for the Porsche Panamera Turbo S E-Hybrid that is also having its debut at Europe's premier motor show it is expected to also have a plug-in battery system that allows for an all-electric driving range of about 30km. A conventional twin-turbocharged 4.0-litre V8 is expected to feature as an alternative.

The carmaker's AMG division celebrates its half-century this year, with the Mercedes-AMG Concept tipped as its celebration model.

The Mercedes-AMG super-saloon will accompany the already announced R50 hypercar, powered by the V6 from the current generation of Mercedes Formula One cars.

Codenamed the X290, it is reported the GT-based four-door is the pet project of AMG boss Tobias Moers, and expected to be pitched as a Bentley Continental GT and Porsche Panamera rival.

Although expected to carry styling cues of the two-door GT coupe, the four-door GT 4 won’t be built on the same chassis, with Autocar in the UK reporting it will get a different platform to the aluminium-intensive structure that underpins the 911 rival.

Instead, the GT 4 will use the modular rear architecture from parent company Mercedes-Benz, and already used for the C63, E63, and S63.

Mercedes-Benz will have a strong showing at Geneva. As well as the GT 4, the carmaker will reveal its E-Class Cabriolet, and a major makeover for one of its strongest-selling models in Australia, the GLA compact SUV.

Special editions of the Mercedes-Benz SL Roadster and SLC coupe will join the X-Class, a luxury version of a worksite-friendly trade ute, on the Geneva stand.

It will also show one of the strangest vehicles to be unveiled at the Geneva Motor Show; a V12-engined, luxury laden folding roof version of the G-Class off-roader called the Mercedes-Maybach G 650 Landaulet. Only 99 of the cars will be built.
