Video: 2010 Mercedes E63 AMG Pumps Some Iron

Well, the previous generation E63 had the same as the M5 (which is around 1.83 tonnes). Subsequently, they have pretty much the same power to weight ratio. This is where the RS6 comes into it. It weighs 200 kg more than both the M5 and E63, but it has around more power. This means, it ends up having the same power to weight ratio as the E63 and M5. However, in a track situation, lugging around that amount of extra weight in and out of corners certainly won't help it. I can see the RS6 being the slowest of the three. The rest comes down to how the new M5 is powered and its weight, but it probably wn't be hugely different from the current M5. The new E63 doesn't look as though it weighs alot less, but its weight is most likely slightly less than the old E63. Also, I can't really see the new M5 having more than 550 bhp. BMW will no doubt bank on weight saving and using new technology to make the M5 faster. Quite an interesting match is brewing up here!

I can definitely see BMW dropping the new V8TT into the M5, because as well as being powerful enough to utterly bowl their main rival, the E63, over it saves them the millions and millions of Euros it would take to create a new engine. It makes perfect business sense, really, and that's what auto manufacturers are - businesses.

Sorry BENZian, but there are to many "if?s" in your comment... ;- )

The reason is simple. AMG clearly has a strategy for this situation. Cleverly, they have decided not to go for an forced aspiration. I think there game plan is to wait and see what BMW comes up with, and get the sales in with the current E63. Once the BMW is released, and a verdict is reached whether the E63 needs morme power, they will add a turbo or two onto the current 6.2 litre V8, or just up the horsepower of the V8 without any extra additions.

The "65" notation has traditionally been reserved for those vehicles originally available in "600" flavour with the V12. So, it stands to reason the E-class will not get the V12 treatment by Mercedes or AMG. However, tuners like Brabus, almost certainly will put the V12 into the E-class.

And then the CTS-V breaks down, lol

We've already discussed this, lol. The E63 is simple the better overall package. It has comfort, massive speed, and its so much more cooler than the boring XFR.

It used to be owned by Ford, up until around 2008, if I remember correctly. It is currently owned by Tata.
