Yes, I know - silly question. However, just out of interest (and to completely put me off the idle thought that one might make an interning change) what's the real world MPG like in a 4.2 supercharged RR sport? I worked out that on my regular commute (with somewhat heave right foot) I'm getting about 20 mpg from the current car - how much worse can these really be?

Or, in real terms - I do about 180 miles for £55 or so in fuel. How does the RRS compare, and (petrol aside) are they ruinously expensive to maintain (2005/6 vintage)?

Depends how you drive it but you'll probably be averaging late teens mpg...

As for running costs, etc... It depends what you're comparing it to but don't forget that it is a 'premium' product! wink

I'm happy with the idea of "premium" servicing costs, but is there much that tends to go wrong/fall off these cars? smile

Id imagine it would be similar to a FFRR given the weight, but I think mid teens is where its at. If you do town driving that can drop to under 10.

The trip computer on my last FFRR was reading 14.2mpg average by the time Id sold it and that rarely went near a town!

I changed my FFRR SC for a TDV8 as I was getting around 250-270 miles for £130 when fuel was slightly higher than it is now.

Commuting will bring out the worst in fuel consumption.

Ouch - ok, thanks for this information. So, basically twice the price in fuel... I'd need to really love one for that to be desirable, so I think I have my answer! smile

'Fraid so!

If I were you and you were really keen on a RR (FF or Sport), you should seriously look at a TDV8, otherwise, the cost of fuel will soon make you think twice about using an SC and, assuming you're paying for the fuel yourself, you'll start to seriously question why your bank account is so empty!

Yep, would be paying the fuel myself. I only have a small commute so consumption that isn't great would be fine... This sounds a little worse than I was expecting though! I'm toying with the idea of a BMW 650 which is why the idea of a large V8 isn't too troubling, but I'd guess you're seeing around 10-15 mpg based upon the costs. Think I'd end up resenting the thing, rather than enjoying the change from a sports car!

As long as you go into RR ownership with your eyes wide open, they are fantastic vehicles.

I for one didn't exploit anything like the full potential of my SC, as it was just so depressing actually seeing the fuel guage drop as I drove!

I recently had an 07 TDV8 RRS with reasonably low mileage and was completing 70 miles a day, mostly motorway (Livingston to East Kilbride). This was costing me a tank of fuel a week, give or take a day). MPG averaged out at 21.4mpg over 3 months of commuting, but would hit the heady heights of 24-25mpg with a light foot. But the noise when you put your foot down meant that was few and far between.

Tyres, I had a bulge appear after a long run and put it down to a manufacturing defect, but that was £250 for a 20" as the other three were only 1500 miles old so I needed to match.

I had an alternator fail within 1 month of ownership so that was a used-warranty job. This was good as it took 3 days to be sorted and apparently involved the front of hte car being taken to pieces to get access.

Everything aside, it was an awesome commuter car, but £100+ pcw was not fun when the only way the price was going was up. Incidentally, the TDV8 also had the RRS spec suspension and brakes.

FWIW - My TDV8 usually gives me about the same i.e. around 24-25mpg. However, if you drive sensibly, it'll give you nearer 29mpg and on a decent run I've even had 31mpg out of a tank (I wasn't driving like Miss Daisy either!).

Interesting thread. I've just been driving a 5 litre S/C and absolutely loved it. Way out of my price range but I'm tempted by a 4.2 in the future. Has anyone driven (or better owned) both a 4.2 S/C and a TDV8? I'm interested to know the two compare.

I loved the sound and, when you need it, urgency of the petrol V8. Can the TDV8 compete?

Depends on your definition of "compete". The TDV8 has more torque but will ultimately lose out to the SC. In saying that, there's strong evidence to suggest that a "chipped" TDV8 will give an SC a run for it's supercharger! Watch this space and I'll let you know very soon!;)

The TDV8 has some flat spots and can be a little hesitant on pull away, but the retune should resolve this - again, watch this space!

They both (depending on which year you buy) have Brembo brakes up front and the same "sports" suspension.

The sound from the TDV8 was part of my reason for getting rid of it ... it was too tempting to put the foot down to hear the noise and feel the torque. And that of course led to more avid fuel consumption. There is a minor flat spot as noted, but because it's a twin turbo the lag is not too crazy. You can certainly compensate for it.

It certainly picks up its skirt when you give it a bit of welly, and its sounds good enough to put the window down and listen. No clouds of black smoke on take off either (unlike my Dad's old TD5 D3).

Power comparison would be:
4.2 S/C: 389bhp (290kW) & 550Nm (405lb/ft)
3.6 TDV8: 268bhp (200kW) & 640Nm (472lb/ft)

Put simply, how fast do you go, or is it more important to consider how quickly you get to your maximum speed?

There are two versions of the TDV8, the 3.6 is good but the 4.4 is much better.

TDV8 does sound worth a look at the absolute least. Much penny saving to do before in a position to need to worry!
