Yet another teaser video of the upcoming 2015 Mercedes-AMG GT has been released ahead of its world debut tomorrow. This particular video looks at the design of the new Mercedes-Benz sports car which the company has previously confirmed will be its most beautiful car ever produced.

Vice President of Design for Daimler, Gorden Wagener, says that the ‘sensual purity’ philosophy comes into play for the AMG GT. Designed to be incredibly pure, clean and modern while also being exciting, Mercedes-Benz believes the AMG GT will be a truly incredible car which will go down in the firm’s history.

Underpinning the Mercedes-AMG GT will be a new twin-turbocharged 4.0-litre V8 engine. This engine is not only important in that it will power the firm’s premium sports car but because it will become Mercedes-Benz’s staple performance-oriented engine. It will underpin the next-generation Mercedes-Benz C63 AMG as well as the next-gen E63 AMG. Further down the road, the S63 AMG is likely to adopt it as will the company’s range of power-hungry offroaders like the G-Class and for the first time, the GLK in the form of a GLK63 AMG.

When fitted to the range-topping Mercedes-AMG GT-S, the 4.0-litre biturbo V8 engine delivers an impressive 503 hp at 6250 rpm. That equates to 126 hp per litre and is joined by an equally impressive torque figure of 479 lb-ft between 1750 and 4750 rpm.

Known internally as the M178, the engine is a completely new replacement for the naturally-aspirated 6.2-litre V8 engine which of course powers the GT’s predecessor, the SLS AMG.

It features the same 83 mm bore and 92 mm stroke as the 2.0-litre turbocharged four-cylinder utilised by the A 45 AMG, CLA 45 AMG and GLA 45 AMG. The turbochargers are produced by Borg Warner and operate at a maximum pressure of 2.3 bar.

Some of the other cool features of this new powerplant is the Bosch piezo injection system which delivers up to seven injections per cycle. Elsewhere, the cylinder barrels are finished in the German marque’s Nanoslide material to dramatically reduce friction and improve efficiency.
