Many years ago I changed my driving style to cope with rising fuel prices; I have now reached the stage where I am contemplating keeping my eyes shut in order to lower wind resistance.

[borat] American cars are rubbish and don't handle... NAAAATTT [/borat]
But seriously though, woah.
What classes as a 'Production car' then? I assume the mega stuff like Veyrons and Enzos don't?

Production includes things like the new Nissan GT-R, Porsche 911GT2s (2008), Pagani Zondas, Koenigsegg CCRs, Mercedes-Benz SLR McLarens, RUF RT12s, Porsche Carrera GTs, Ford GTs, Ferrari 599s, Lamborghini Murcielagos and so on. So there's some exotic tin in there, for sure! You can see some others here: en.wikipedia.org/wiki/Nordschleife_fastest_lap_times

Theres a feature on the engine in this months Hot Rod, certainly is a piece of kit, it actually looks as if it HAS been thought out, Just Love the Supercharger, its the inlet manifold, and bolted onto the top is an intercooler, cant wait to see what the tuners get out of it, recon on 1000hp without opening the engine, any takers on that figure.

Atmo V8 Power . No slicks , No gas + No bits missing . Doing it in style. Austin A35van, very different------- but still doing it in style, going to be a funmoble

Wind tunnels really are starting to ruin cars. This looks good and slippery, but probably isn't This looks horrible, but will no doubt provide meaningful down force

That engine cutaway, is it the modern one?
Pushrods, how quaint.

Yup, pushrods, two valves per cylinder! As is the previously all-new LS7 V8, too Putting the cam in the block and actuating the valves, through rockers, with pushrods works very well. The main advantage is that, especially in a V engine, there's only one camshaft. Also, the camshaft drive is a lot shorter which gives better accuracy in timing. It also makes the engine and packaging much tighter and smaller ,leading it to be lower, narrower and lighter.

I had a drive of a new AMG 6.3 recently. For those who have held the throttle open on a 'Busa ,you will understand the feeling. Chev? ha ha ......no wonder GM USA is in the cactus toilet.

End of post lacks sense I'll compare the AMG 6.3 with the LS2, seeing as you've prompted me The AMG 6.3 makes 510BHP at 6800RPM and 465ft.lb. Weighs 200kg, bears a sophisticated quad variable camshaft system, 4 valves per cylinder and can only return approximately 12mpg around town, or circa 20 on the motorways. So the AMG 6.3 racks up as 128BHP less power, 139ft.lb less torque and is ~3mpg less efficient than the 6.2 LS2 in the Corvette. Oh and the LS2 engine weighs about 30-40kg less. And is considerably less complicated....... Both are very different engines, with very different takes on achieveing the desired results (one is NASP, one is FI, for example). Both deliver. One more than the other

I sort of expected something more like this from the folks at Browns Lane.

the Corvette engine is alloy and all new not cast iron and shares no parts with the gen 1 small block.
when the Gen 3 engines were designed they road tested two versions on test tracks for some time, one with pushrods andone with 32V DOHC and the pushrod engine was dynamically better. The centre of gravity is lower, they have a tendancy to make more torque lower down and you can get faster valve lift off the seat. Also a OHC or DOHC V8 is wider and taller which makes packaging more difficult and GM want to put his in the Corvette as well as a buch of other vehicles. Look what a turd the Ford OHC V8 "modular" series is and the pushrod Chrysler Hemi if you want to see why pushrod engines still have thier place in performance cars.... Especially the heavier ones...

And, I hasten to add (correct me if I'm wrong) the LS series engines cost A LOT less than their more "modern" euro counterparts. Can you buy a modern BMW V8 for a couple of grand? I don't think so, but you certainly can buy a crate LS1!
