Why bother with a 500bhp V10 if....

Any enthusiast knows exactly how fast each car on the road is and so some other point is being made when something like a Transit wants to hassle something like an M3.
Its eithera, That they are the better driver despite being in a slower car.

When you go faster, you get there quicker, it is a simple thing. Also motorways are a very safe place to go fast, as unposed to pushing on on country lanes. Which is quite the opposite.
Except that doesn't always apply on the German autobahn. Unless you have a large fuel tank you will spend more time stopping for fuel than you have saved by driving twice as fast! Fuel efficiency at 140+ mph is truly shocking, with aerodynamic drag (wind resistance) increasing at the square of speed.

And V10 M5/6s do not have a particularly suitable fuel tank capacity. Something they addressed with the F1x Ms as they do have a larger tank than non-Ms (as well as more efficient FI engines, giving much greater range).Quite so that range between fills is a greater annoyance in thirsty cars than the nominal consumption. 15-20mpg is at least tolerable with a ~100 litre tank. ~70 litres in the M5/6 is poxy.
Was there not a Top Gear challenge involving an M5 and a 535d having a "race"? Similar top speed and hugely different economy at speed meant the diesel was quicker from A to B in the real world in that situation, purely due to less time spent stopped at fuel stations.

Have you dreamt that?
I remember the 535d vs 545i round the track but don't recall any other e60 M5 pieces save the original one Clarkson did.
Yup, except they also did the E61 M5 touring vs the E63 AMG Wagon. They did do a 535d vs 545i, where the 545i was quicker (it does have more power....); I still think they should have tested it against the 535i, but there we go.I remember the 535d vs 545i round the track but don't recall any other e60 M5 pieces save the original one Clarkson did.

They didn't test it against the 535i because in the UK there never was an E60 535i.Ozzie Osmond said:

The speed and style of my motorway driving will depend largely on:
What car I'm in;
Where I'm going;
What the time is.
A sensible and proportionate response on PH. Surely not...What car I'm in;
Where I'm going;
What the time is.
Floor it every gear to the redline just for the hell of it
I would get more man points for that though surely...
As with troubleatmill, If I red line it in every gear I'm going 60 in first and nearly 100 when I change out for second.
not really viable is it?
After all I wouldn't want to get dead would I?

As others have hinted, the motorway is not the place to demonstrate your cars BHP - its pointless as pretty much anything can break the speed limit with ease. If I'm going to exercise the potential of a car, I'm more likely to do it when (hopefully) nobody is near and watching.

You never use it. On the drive home from work most evenings I see a lovely dark blue '55 plate BMW M6 with the 5.0 V10 and every single time I see the guy (which is about 2, maybe 3x per week) he is sat on the motorway on a 55mph cruise.
It's not like sometimes he's doing 65-70, sometimes 55, it's literally 55mph every day. Surely he'd be better off with a 630i if he wants a 6er bmw with a smooth engine, or a 635d if he wants more economy....
Who knows, maybe off the motorway when he turns off he nails it to over 8000rpm
Either way, fair play for having the car, but it just seems a waste of a glorious engine.

I'm not seeking any sort of confrontation. If I was, I'd be picking cars better than TDi Golfs etc.
If someone flashed their lights at me I'd happily move out of the way. If someone decided to glue their front bumper to my rear bumper thinking it is fun to race an M6 in their Tdi FR or whatever, they need their head re-testing.
You did mention Carreras and 335ds too earlier.If someone flashed their lights at me I'd happily move out of the way. If someone decided to glue their front bumper to my rear bumper thinking it is fun to race an M6 in their Tdi FR or whatever, they need their head re-testing.
What's your personal pleasure in owning your M6? I can imagine that it is an impressive car.
It has not been all plain sailing and has been a troublesome car but when it works, it is a monster and to me, a reminder that hard work does reap rewards!

Nonsense. I suspect you haven't done much autobahn driving.I save many many hours driving anything from 90 to 155 mph in Germany
and it only ever costs me about 2-3 mpg. BMW 325 Auto.
Indeed, it costs me far more to drive in town than it does
on the autobahn.

You've only quoted one factor amongst many many factors at work.A more accurate picture would be produced by taking into account
all the other significant factors.
All the graphs I've ever seen say fuel consumption in practice
reduces linearly with speed over about 150 kmh.
Of course, 140 mph could be a maximum, with the average far
far lower, like maybe 90 mph.
There are such things as roadworks, lorries, traffic jams,
other slower drivers and even black Audis driven by grandmothers who
refuse to go over 180 kmh ;->

I find that very hard to believe - I found that my 530i manual was into the teens mpg wise at 130-140ish mph on the Autobahn, whereas it had been doing high 30's at 70mph. The fuel economy penalty for such high speeds was very significant indeed. At 155mph the mpg needle looked like it was on about 10!and it only ever costs me about 2-3 mpg. BMW 325 Auto.
I also found that despite crossing the entire country the number of people flashing past me at 140+ was very small - most people just didn't seem to drive at VMAX.

The reason why you get such good fuel economy is that you ticked the flux capacitor option.A more accurate picture would be produced by taking into account

You see, when you hit 88 you see some serious s
t. Skip over the rest of your journey and arrive at your destination before you left.Amazing more people dont spec that option really.
