There isn't much information available about the technical bits belonging to the AMG GT, but we do know enough to form a rather praising opinion.
For example, we know that one of the engineers in charge of the suspension kinematics and circuit performance of the Porsche 911 (991) defected to Affalterbach a couple of years ago, so his experience might prove pretty helpful in the development of the new AMG model.
We also know that it will use a twin-turbocharged, four-liter V8 that should offer much better performance than the epic-sounding M159 in the SLS AMG, while also delivering the fuel economy of a V6 engine.
Internally-codenamed M178 for the AMG GT (C190), the all-new V8 will feature two twin-scroll turbochargers situated inside the cylinder lines, just like BMW's S63 engine and Audi's 4.0 TFSI.
As its output goes, it should offer at least 500 hp in the base version of the model, with an S-Model variant to deliver at least 550 hp, while a future Black Series may very well pass 600 hp.
Based on the shortened platform of the SLS AMG, the GT will be slightly smaller and have a lower weight than its big brother, while its pricing should situate around that of the Porsche 911 Carrera S and/or the Jaguar F-Type Coupe, both of which will be its major competitors.
Despite this, it seems that Mercedes-AMG engineers are benchmarking the car against much more capable cars, with the Nissan GT-R and the Porsche 911 Turbo (991) having been seen more than once near pre-production AMG GTs.
The following batch of spy photos depicts no less than three Mercedes-Benz AMG GT (C190) models being benchmarked against an SLS AMG Roadster and a Porsche 911 Turbo S somewhere in Lapland. We hope to have more information about the car in the upcoming months.
