AMG goes on to add the fact that technology of performance petrol powered engines are 'converging with diesel tech' and cites the example of their current twin turbocharged 5.5-litre V8 engine. With direct injection enabling very high compression ratios (of around 12.0:1 for a turbocharged car), turbocharging and all the usual high efficiency systems a petrol powered V8 can achieve pretty good fuel consumption and C02 figures. Actually, it isn't that close, diesels are still more efficient per drop of fuel used but you can't beat a petrol powered V8 in terms of sound. Imagine a clattering, noisy AMG V8 instead of something that sounds like a Messerschmidt World War II fighter plane. It wouldn't be right.
Do also imagine a Mercedes-AMG without its fantastic throttle response and a rev-limit of about 4,500rpm. That'll be pathetic!
It goes to show again that Mercedes Benz are indeed a company that can ignore trying to be politically correct and give us what's truly important - glorious petrol powered thrust, revs, sound and fun.
