      AMG 5.5 Liter V8 Biturbo

      • Perfect combination of performance

        The AMG 5.5-liter biturbo engine combines performance with efficiency to a previously unknown extent. This is made possible by a unique combination of innovative high-tech systems such as direct petrol injection with piezo injector, twin turbochargers, air/water inter-cooling and the Controlled Efficiency ECO Start-Stop function.

         

        Mercedes-AMG is systematically following the trend towards increasing efficiency with its V8 biturbo engine: with a displacement of 5461 cubic centimeters it is precisely 747 cc below the 6208 cc of the naturally aspirated AMG 6.3-liter V8. Nonetheless, it considerably betters it in terms of both output and torque. The AMG 5.5-liter V8 biturbo engine develops a peak output from 386 kW (525 hp) and maximum torque of 700 Newton meters to 430 kW (585 hp) and 900 Newton meters with Performance Package. The torque curve in particular shows that no other engine in this output class is able to match the figures delivered by the AMG biturbo unit.

         

        Despite an increase in output up to 44 kW (60 hp) and in torque by 170 and 270 Newton meters compared to the naturally aspirated V8, which develops 386 kW (525 hp) and 630 Newton meters, AMG engineers have been able to reduce fuel consumption and CO2 emissions considerably.

         

        The achievement of these efficiency and environmental aims has no negative effects whatsoever on dynamic performance. On the contrary, as the AMG 5.5-liter V8 biturbo fully lives up to AMG's brand commitment to "Driving performance”.
