Mercedes-Benz, AMG considering electric turbochargers

Article by Christian A., on July 11, 2014

Audi has recently revealed the RS5 TDI Concept, a vehicle powered by a diesel engine that featured an electric turbocharger, providing a staggering power when starting off. Still, Audi isn’t the only German manufacturer that considers using electric turbochargers on its production models as Mercedes-Benz also plans to use it.

Mercedes-AMG Petronas F1 team is already using the electric-assisted 1.6-liter turbocharged V6 engine and thanks to the innovative turbocharging system it dominates the 2014 season.

In a recent interview with Drive, AMG’s head of powertrain development Jochen Martin Schmid said that some ideas of the concept used by the F1 cars could also be transferred to road cars.

He also admitted that one of the new-age technologies that AMG is studying is electric turbocharging, where the compressor is powered by an electric motor and not by the exhaust gases, in order to provide the maximum boost earlier.

Mercedes-Benz’ latest AMG model is the S63 AMG Coupe, which uses a 5.5-liter V8 biturbo engine that generates 585 hp (430 kW) and 900 Nm of torque.

This model accelerates from 0 to 100 km/h (62 mph) in 4.3 seconds, while the S63 AMG Coupe 4Matic sprints from 0 to 100 km/h (62 mph) in 3.9 seconds. Both models offer a top speed of 155 mph or 250 km/h.

Still, the German carmaker will debut the all-new 2015 Mercedes-AMG GT at the Paris Motor Show. The new model will be powered by a brand new 4.0-liter V8 engine that generates 510 hp (375 kW) and a maximum torque of 650 Nm (479 lb-ft) of torque between 1,750 rpm and 4,750 rpm.

Gorden Wagener, Vice President Design for Daimler AG, called the new Mercedes-AMG GT as a sports car in its purist form. He remarked that the AMG GT is a contemporary sports car defined by breathtaking proportions, dynamically sculpted surfaces and flowing lines and is an embodiment of the spirit of glorious Mercedes sports cars. Wagener added that AMG GT fuses beauty and intelligence.

Representing the sensual purity of sportiness and emotion, the new AMG GT is marked by signature rear-wheel drive proportions. Its front mid-engine layout ensures that the sports car has an optimal weight distribution for superb levels of driving dynamics. Its dynamic appearance is defined by a long bonnet with pronounced powerdomes as well as a set-back passenger cabin. This look is also defined by its large wheels, broad rear end and a large tailgate.

The muscular appearance and sensuous character of the AMG GT is made possible by its positively arched surfaces. When viewed from the side, the AMG GT reveals a stunning dome-shaped arched roof line and frameless doors, while a muscular detail on the side wall makes it seems that the sports car is moving dynamically even at a standstill. In addition, the surfaces and lines flow – in a tapered manner -- from the sides into the rear end.

Interestingly, the new AMGT GT has no lines in the shoulder region, but has one lower down that picks up in the rear bumper to dynamically stretch the body while making it seem lighter. The sides also feature air outlets with two fins just like that on all Mercedes sports cars. The sports car also has no visible aerials that might disrupt its overall looks.
