M5 (F10) vs E63S AMG vs RS6

[Andy M]

I've not seen these Auto Express runs previously posted.

The M5 easily outruns the Merc:

But then have a look at the time of the RS6:

The RS6 is obviously a rapid machine, but had the M5 hit its limiter? I recall the M5 does 0-150mph in the low 18s.

Is a bit sus but they do launch very well & will hit 62 in sub 4secs, however the GT-R is closer to 3 so odd the M5 & RS6 beat the GT-R.

I'm surprised by the time of the S63 too.

If you recall the Chris Harris M6GC vid, he hit the limiter pretty quickly and the AMG then sailed by:

Given the 1.8km distance used, I can't see how a number of the cars wouldn't have hit their 155mph(ish) limiters?

Also, back to the original question. Quite surprised the M5 won. There are have been a fair few American Automotive videos where the E63S wins in a straight line.

Remember, the US E63S is 4 wheel drive (the UK is rear only), so over a short distance the US Merc would have the advantage.

I think the M5 is the faster car once moving due to a better gearbox.

Just been in touch with the guy who ran the F10 M5. The RS6 was derestricted & the M5 wasn't so was done by 160mph. That makes sense as to why the RS6 looked so rapid in company.

No idea why the GT-R faired so badly as they're not restricted.

How soon into the run did he hit the limiter?

It's ridiculous that BMW UK don't offer the car de-restricted. It may only be useful on a handful of occasions during the cars lifetime, but their M cars are supposed to be halo products.

Car and driver got an RS7 to 60 in 3.4 seconds but that does include a 3ft roll out (worth 2-3mph) and you're knocking the 2mph off the top as well compared to the 0-62 quoted by Audi.

So you can add a couple or three 10ths to that number giving a 0-62 of about 3.7, still very impressive.

The M5 has been quoted at 3.7 to 60 so I'd be surprised if the RS6/7 couldn't improve on that.

He reckons 4-5 seconds so a fairly significant difference.

Exactly why i got mine removed as is stupid having such a powerful car limited to 155mph, especially for those owners who track their cars & take them across to Germany.

Hypothetically, how would somebody go about this..? (via PM if necessary!)

196mph to be precise ....which is only a 3% variance at that kind of speed and therefore reasonably precise.

What did the official limiter-removal cost on your M6 Andrew? Was the driver experience worthwhile?
