I really dont think you are ever gona get mid to high twentys regardless how you drive, your forgetting its a v8 and pushing eight cylinders its always gona be high on fuel consumption.Spare a thought for me my every day transport is a 4.6 range rover and i get ( wait for it) 9mpg around town and 15mpg on a run, but as has previously been said with your car its not mpg but spg, keep your car and buy an old dog for work


Beg to differ -- mine regularly clocks up 27mpg on an all-motorway run, in the UK anyway. Somehow French m/ways seem to use more juice...

And blatting round country roads, now that's another matter.

M@,

If you can't improve the comsumption, maybe you should come at the problem from a different angle and try doing something about the fuel cost . This could be the opportunity to be a TVR pioneer and switch to LPG ! Ok, ok I know I'm probably going to be shown the door on this one (I'll check in a couple of hours to see whether my profile's been deleted ), but maybe you could persuade one of the TVR specialists (or PW ) to invest some development costs - there must be a fair few people who'd like the idea of saving a few quid on the fuel bill. Besides, you must have far too much boot space after your S2!

I'll get my coat...

Just done my sums - cross country run from Edinburgh -> Newcastle & back at the weekend, including driving around town, and a little thrash "just take my neighbour out for a run & show him what it can do" - 23MPG
I've done a lot better on motorways - no doubt would have been more economical with the hood up too...

Maybe you should invest in a Mark Adams chip - even if it doesn't help the MPG, it should help on the GrinPG

You'd be surprised!

Having just driven up to Scotland and around the western highlands, knocking up 2000 miles in under a week, needless to say we had to fill up quite regularly (and as many opportunities to calculate fuel consumption!). OK, so this is going off the odometer readings (which didn't seem to be too far out from the map).

Over the entire trip we averaged 24 mpg.
Quite a bit of that was humming along on the motorways there and back (at scalp massaging speeds with the hood down!) when we averaged about 22 mpg.
Our worst day (fuel economy wise) but best day driving! got us down to 18 mpg.
...but, one day when it was raining haggis, neeps and tatties and the opportunities to overtake seem to disappear, and we had to follow the Hydro's emergency generator trailer through road works for what seemed to be the best part of the day, we got 30.2 mpg.

Driving steadily, around 50 - 60 mph, on relatively flat roads, without too much right foot on either pedal, it can be done.... but I'd be if I'd drive like that if I had a choice!! Just enjoy driving the TVR.

MC

Hi all...
4.0 managed to consume almost exactly 20 gallons to do the 460 miles, or in other words a poultry 23mpg.



How fowl!

But seriously, you should do better than that on m/ways. Why not buy mine instead?

An mpg of low to mid twenties would seem reasonable -that's what I get.
Consider why you might chose to eat at a good restaurant rather than a Little Chef. They both sell food, but if it's just a matter of filling your belly, then the Little Chef will do, but if you want a better quality dinner, then you pay the higher cost for the restaurant.
So it is with motoring - to get from A to B economically, drive a saloon.
There's a higher price to pay for performance motoring enjoyment - servicing, insurance and of course - fuel costs....you consider the factors and make your choice.

Well thanks again all for the continued contribution that has borne out my thought that the car should do more than 23mpg on a steady motorway run, thanks also for the thoughts on fuel and tuning etc, much appreciated...


...and for those of you coming out with all the stuff about, what do I expect from a sportscar, and why did I buy it then:

I wasn't ever complaining !! I just thought there might be something wrong with the car not the marque !!


Thank you

If the speedo overreads by 10% then does not the miles covered also overread by the same. So its not 20 gallons into 460 miles but into 414 miles!!
My 450 chim does 17-24 mpg, my 1000cc MOTORCYCLE does 31mpg and my aeroplane does 17mpg(at180mph cruise). So what - its fun!

Being the caring person that I am I conducted a little experiment this weekend on my trip to Donington.
I managed the trip from Portsmouth - Donington - and back as far as Newbury on 1 tank, giving me 28.7mpg.
This was mostly motorways (and the associated speeds ) but on the way back due to the M1 being closed it was queing A42/M42 all the way to Birmingham.

You know what I love? I love the roar when doing about 85 and you just plant the loud pedal, the noise between 3000 - 4000rpm is just fantastic!

So Matt, good mpg can be achieved even when you are having fun.

I can't believe you guys - I must have lead in my boots - I get 23 +/-1 mpg, including a lot of motorways (4.0 Chimaera).

Regarding the LPG, it's been done - I saw an lpg-equipped Griff advertised in Autotrader last year. Loads of Range Rovers are converted so a standard conversion must be readily available.

However the fuel may be half price, but the mpg will go down too.

One more point I overlooked: I used to get much poorer mileage until I had the fuelling remapped by Mark Adams. I now get more mpg and better performance...
