Mercedes-AMG unveiled a new 4.0-litre V8 biturbo engine that will make way to the new Mercedes-AMG GT car. The company claims that this eight-cylinder unit features better power delivery, lightweight construction and environmental compatibility. This new AMG V8 delivers 510 hp of power and 650Nm of torque. The new sports car engine follows the V8 tradition that started in 1967 with the M100 in the legendary 300 SEL 6.8 AMG racing car.
Powerful V8 engines have long been a core competence at AMG, the performance brand from Mercedes-Benz. Innovative and exciting high-performance engines come out of the location in Affalterbach. On this occasion, Mercedes-AMG GmbH is entirely responsible for both development and production.
Expressing his views on this new engine, Tobias Moers, Chairman of the Board of Management of Mercedes-AMG GmbH said, “V8 engines are an integral part of the AMG philosophy and the brand’s commitment to ‘Driving Performance’. The V8 biturbo engine for our new GT is going to delight our customers!”
Adding his thoughts on the new AMG V8, Christian Enderle, Head of Engine and Powertrain Development at Mercedes-AMG said, “The new AMG 4.0-litre V8 biturbo sees us presenting an exciting and powerful sports car engine which, thanks to a number of measures, also represents the next step in efficiency.”
The new AMG V8 engine sports two turbochargers which are not mounted on the outside of the cylinder banks, but rather inside the V configuration – experts call it a ‘hot inside V’. Mercedes says that this design provides a compact engine design, an optimum response and low exhaust gas emissions.
