Nice driving report here of the Mercedes-Benz CL63 AMG. Enjoy!
Large turbo engines aren’t meant to sound like this. Nor are they meant to respond to the throttle like the CL63, either. The secret would seem to be not more turbo pressure, but less. Because the engine is still large, Mercedes can afford to blow only moderate amounts of boost through it, which means the engine can run a compression ratio of 10.0:1, a number you’d normally associate with a normally aspirated car. So there’s no off-boost lethargy at all, nor any sudden uncontrollable bang in the back when it kicks in. Any revs in any gear and the thing just flies.
In fact, its character and sound is more akin to the old 5.5-litre supercharged motor AMG used before the 6.2, only with much more shove. We loved that old engine, and anyone who buys this new one in any of the AMG products it will filter into are going to love it too.
