I had 34 miles left on the meter today and brimmed the tank I got 70.73 litres in against a capacity of 80 litres, so I had just over 9 litres or two gallons left which is pretty accurate given the MPG I get round town.

How are you finding it on fuel? I got 23.1mpg on my 150 mile drive down to London this morning - my best eco run yet...
What? I think you may have an issue there. Was that a manual calculation as I get more in the DB9...
23mpg from 560hp 500ft/lb 5 seat, 5 metre long car, weighing 2 tonnes isn't bad.
Sorry, thought he had a 335d!

Stating the obvious I know, but that's quite a stark contrast in fuel economy between the M5 and 535d - give or take 20mpg on a run. Aouch!! It would be great if you could switch engines for the weekend!

The extra 250 ponies come with a cost!

It certainly does - especially if say an M5 owner only uses 313 bhp of his 560bhp and gets 20mpg - so a question is does the extra 250bhp really worth the loss of 50% of the mpg?

Yes, if a car is more than transport. And anyone who purchases an M5 surely has this mindset.

Serious question when does it become non true?
Is it when its a 560bhp M5 moving up to let's say a theoretical 800bhp M5 again losing 50% of the M 5's economy in the process? Is it not when its simply irrelevantly too fast for the public roads or is it just that the max power they make it in is to be purchased?

(Fun can easily be had in a low power hot hatch or track vehicle)

Yep caught out -- very envious



Wills2 on a frequent basis do you use full load and rev out in at least 1 gear.

With the weather we have in Yorkshire at the moment it spins up in 1st 2nd 3rd and 4th, wet and 7c at the moment.

So I can actually floor it in the 1st and 2nd but have to hold on, the TC is strange it will sometimes allow loads of wheel spin in 1st and 2nd when the wheels are pointing forward but other times cuts the power straight away.

The light can flash when exiting a slow speed corner for seemingly no reason, I haven't put it in MDM yet or had the TC fully off.

Can't wait for some dry warm weather so I can put the power to the road rather than it just spinning away.

I put another 250 miles on mine today including some fast paced A road running over a wet A69 Newcastle - Carlisle and later the A5 in Shropshire. As Wills2 says there's simply no way you can get the power down in damp conditions - even feeding it in smoothly the back end is squirming to break loose when you're accelerating hard even at 70+

Of course you don't have to use full load to make decent progress, and overtaking lines of traffic today was still relaxed and effortless at what felt like 70%

The A5 later in the day was dryer and I did manage to get my foot to the floor on a few occasions, but even then I'm still short shifting at 5.5-6k. I'll start running it all the way to the red line after its running in service next week.

I was down south last week dry and about 13c, from 70mph the acceleration is brutal it punches as hard from 70 as Golf GTI does from 0.

It's just too cold in the grim!

Looking at your car history (very PH may I add) how does it compare? Is it too fast for the road most of the time?

I found the C5 RS6 on B roads simply way too quick to the point I was far too often backing off and dabbing he brakes on straights as you'd be from 45 to 100/120 in no time at all and even then it wasn't letting up simply getting into its stride.


Things I miss from that car.

The wonderful noise - be it starting it up burbling around, tunnels or simply WOT acceleration.
The looks - let's be frank it looks "bad ass" super aggressive
The 200mph speedo
The brakes - even though they were towards the end of their lives are simply leagues better than what I have now (and I'd say the current ones are very good but simply don't compare)
When someone asks so what do you drive - oh an RS6 identical to the one featured in layer cake.
The performance - nothing beat me during my ownership. Be it the occasional traffic light GP (rare) to idiots up my bumper on the M way so simply give it a blast to get rid of those plebs and I'm half a mile plus clear of them.


Down sides - woeful economy
Shocking tyre wear
Eye watering servicing and part replacement cost
Niggling thoughts about the chocolate autobox to fail
It wouldn't go into 5th until 60mph + yet could easily drive it from 30mph with the torque and power.
Harshest ride I've ever had literally crashing over bumps or imperfections.
Stopping for a full up twice a week
Having to use super unleaded only.
Ancient sat nav.

Still an itch I had to scratch who knows the next petrol could be replacing the 535d in the future

Maybe once generally it was simply RS6 - to which many said what's that.

Same here with my F10. I've just filled it up showing Range 25 miles on the dash and it took 62 litres of fuel.

I regularly used to get 68 or 69 litres into my E39 when filling it. I don't think everyone else in the thread really gets your point - the way it handles 'reserve' is irritating and limits range, on a long run thats almost 80 miles I'd have given up in range due to it implying the tank was empty when it wasn't. My E39 doesn't behave like this - the range is the range and 0 miles means 'you've got 10 if you are lucky, you fool'. Then I can fit 68-69 litres in meaning I get further on a tank than I otherwise would have.

Was away to say the same, regularly see close to the capacity when filling up.
