5.5-litre twin-turbo lump. This, of course, replaces the old 6.2 and shows just how complex a modern V8 has to be to stand a chance of social acceptability these days. So that means piezo-based direct injection, variable cams, 'smart' ancillaries, two turbos, air/water intercooling and more besides. I remember chatting with the AMG engineers when I first drove this engine on the CLS63 and, refreshingly, for all the tech on the engine one of the things that got them most exercised was making sure it sounded proper.
Not the easiest when you add turbos of course, but they seem to have done a cracking job and the AMG thunder is present and correct, now overlayed with just the faintest rush of forced induction and a bit of a crackle on upshifts. It doesn't quite match the raw savagery of the outgoing 6.2, but equals the immense pulling power of the old M113 5.5-litre Kompressor V8 with vaguely acceptable running costs too. And it's obviously relatively easy to turn it up a bit too, which makes the near six grand Mercedes charges for the 557hp Performance Pack Plus hop-up seem even more outrageous.
the 458 Italia we took down to Sunday Service. And the contrast couldn't have been greater between AMG's classic chugging V8 rumble and the 458's flat-plane howl. It looks great too with the two red crackle-painted intake plenums topping the throttle bodies and 'Testarossa' cylinder head covers. I drove the MP4-12C briefly the previous week too and though it sounds a lot better now and has that 'swept away on boost' sensation you'd expect, the 458 engine still has bags more charisma. Which is what you want out of a supercar.
And now? Well, waiting for me at Ferrari North Europe was my transport for the next couple of weeks - a V8 supercharged Range Rover Sport. More the old-school chugger compared with the polar opposite AMG and Ferrari engines, the JLR V8 has a lot of the feel of the aforementioned AMG Kompressor 5.5. It also gives the Range Rover a lovely V8 woofle like that of traditional Rangies. Going straight to that from the 458 it did feel like I was going to topple over the first time I went round a corner, but I've got used to it now.
