Mercedes AMG GT first look

This is the new Mercedes-AMG GT – the second series-production model from Mercedes-Benz’s performance car division in Affalterbach, Germany, following on from the recently discontinued SLS AMG.

The rear-wheel-drive performance coupé shares elements of its body structure with its predecessor and is the first Mercedes-AMG model to use a newly developed twin-turbocharged 4.0-litre V8 engine.

“With the new GT, we are positioning Mercedes-AMG even more aggressively than to date,” said the CEO of AMG, Tobias Moers.

Buyers will be able to choose between a standard GT and a more powerful GT S, although only the GT S is planned for delivery initially. The two are set apart visually by different bumpers, tailpipes and wheels.

Both GT models are powered by AMG’s new ‘M178’ engine. Developed from scratch, the direct-injection 4.0-litre V8 is unique among production road car engines in featuring twin turbochargers mounted inside the cylinder banks. This configuration makes for a compact design, optimum throttle response and reduced emissions, claims Mercedes-AMG, because of closely coupled catalytic converters.

The new engine receives dry-sump lubrication and is mounted behind the front axle line in what Mercedes-AMG describes as a front-mid positioning.

It provides the standard GT with 456bhp at 6000rpm. With added boost pressure and other internal tweaks for the GT S, the 90deg V8’s outputs rise to 503bhp at 6250rpm.
