Two things leapt out at me from the Mercedes-Benz pre-Paris motor show party and neither of them had anything to do with the mildly tweaked B-class on show there.
First is Mercedes’s assertion that its new twin-turbo V8 is actually more economical than a rival’s twin-turbo six-cylinder motor, and you don’t need to look any further down the road than to BMW in Munich to know which one is being talked about.
In that instant everything I thought about downsizing to smaller engines with fewer cylinders went up in smoke. Both engines are new and twin turbocharged, but one has 4-litres and eight cylinders, the other 3-litres and six cylinders.
To all the doomsayers who claim the days of large capacity, multi-cylinder engines are over, Mercedes for one appears not to have heard.
The second point was an aside from engineering boss Dr Thomas Weber who said this engine would mean even more V8 engines, not just for AMG but Mercedes-Benz too.
And why not? At the moment Mercedes makes four V8 engines, in 4.0, 4.7, 5.5 and 6.2-litre capacities. This clearly will not last. What Weber appears to be saying is that AMG will build 4-litre engines, presumably at a volume to enable it to replace the 4.7-litre engine, the only V8 not to be used in AMG cars. And does AMG have enough capacity to take this on and retain its treasured ‘one man, one engine’ hand-built philosophy? We shall see.
In the meantime, I can see the new engine becoming in time the only V8 in the line up. It’s an entirely modular unit that really is two 2-litre fours (such as you’ll find in an A45 AMG) sharing a common crank and its current maximum output of 503bhp is barely scratching the surface of its capabilities.
