Mercedes is claiming the new S 65 AMG is the most powerful vehicle in its segment of the market.
The AMG 6.0-litre V12 biturbo engine delivers 630hp with a maximum torque of 1000 Newton-metres, allowing the car to accelerate from 0 to 62 mph in 4.3 seconds. Top speed is electronically limited to 155 mph.
With a fuel consumption of 23.7 mpg (NEDC, combined), the new S 65 AMG is also the world’s most fuel-efficient V12 high-performance saloon in terms of power and torque, according to Mercedes. The range-topping 12-cylinder model already meets the requirements of the EU6 emissions standard, which is not due to come into force until 2015.
As before in the SL 65 AMG roadster, the engine is combined with the AMG SPEEDSHIFT PLUS 7G-TRONIC. Unlike in the direct predecessor of the S 65 AMG, which featured an AMG SPEEDSHIFT five-speed automatic transmission, the seven-speed automatic transmission with its wider ratio spread results in a lower engine speed level; this in turn helps reduce fuel consumption. Efficiency is further improved by the fuel-economy converter, reduced-friction bearings and transmission oil heat management.
Just like the S 63 AMG, the S 65 AMG features a lithium-ion battery. With a capacity of 78 Ah, the lithium-ion battery replaces both the starter battery and the backup battery – resulting in a weight saving of over 20 kilograms.
The S 65 AMG also features the AMG sports suspension based on MAGIC BODY CONTROL, which comes as standard with ROAD SURFACE SCAN, Mercedes’ new “suspension with eyes” technology.
The AMG V12 will make a double world premiere simultaneously at the Los Angeles International Auto Show and at the Tokyo Motor Show towards the end of this month.
