I am buying a car very soon and just want to know if I should rule out the C5 totally at this stage or not. What is the real fuel consumption that you get with one of these?

They are a dream car of mine but don't want rediculous bills while I am just getting started here in the UK.

Cheers.

I used to have a C5 auto, and from memory it averaged mid-20s mpg (mainly motorways, driven fairly fast and using the acceleration when possible). To me that's good...to others it'd be ruinously expensive!

I borrowed my Mother's C5 yesterday to go down to the Claremont open.day yesterday, it is an auto convertible and did around 30 mpg, keeping it legal with the speeds.

Incredible feat for a 350 HP 5.7 litre car.

I know it does sound good for V8. Just have to work it out though because I am used to L/100k's. I have always wanted a Vette BUT I don't want to buy it and regret it. I would love to keep it for a long time. I have no garage at the moment and the LHD might get tiresome for a daily.

I've heard the Audi TT 3.2, Focus RS and even Megane F1 do in the mid 20's too. They are a 6 cyl, turbo 5 and a turbo 2.0L 4!

If the Vette was truly equal to tho cars I would probably just take the risk. I don't want to buy it and then find out I need a second run around though.

Need to work out theL/100 vs MPG smile

The cars you have mentioned are boring in comparison. I've been driving LHD for many years and dont find it a problem.I dont think you would ever regret buying one.

I hear what you are saying. The other cars aren't a Vette but I need a daily. The Vette would be a keeper for me if I bought it and at this time while living with my In-laws it would be parked in the driveway.

I have had Trans Ams and Camaros before but they were aways my second cars. The Camaro I drove only on rare occasions as it was show standard. They were surprisingly cheap to run "for what they were" but I always had a work car to run around in.

Don't forget that Optimax 98 is only about $1.30 in Australia and here it is more like a £1.30 which like $2 Aussie which is a big increase in running costs 50% more to run here than in Australia!!! Ouch!

Regular 95 octane fuel in UK is fine. I use 98 when I can get it but unless you're pushing hard and the temperatures are high you'd be fine on regular.

I have an A4 and I average about 20 in normal use. I can get 25+ on a run at 65 to 70 but when I get stuck in slow traffic I've seen as much as 31 mpg.

The silver/gold C5 vert is what replaced the missed black C5 - the yellow coupe is also hers.

They really are that good. Of course that will come down if you drive it as it was intended...

My C4, so old iron first generation small block, would do 18-20 mpg, could get up to 22 on a run, that's with no torque converter lock up and technology 24 years old, so they were pretty good for what they were back then, certainly better than contemporary Euro big engined cars.

The conversion gives 9.375 l/100km.

Best MPG i ever managed was 34mpg from a Peugeot 405TD- on a run -other than that it has been stop start urban driving in 4 cylinder family fare - with 12 cylinder MPG!
If i did own a Corvette -with my above driving routine and mpg history i reckon -under 10MPG and 15 on run.

What's the formula for that? If it gives 9L/100 that is not much more than a Toyota Corolla! I'm sure it's more than that.

In case I've got it wrong 30 mpg

Divide by 5 multiply by 8 to give km/gallon

Gives 48km per gallon

Divide by 4.5 to get km/l

10.66666 km/l

100 divided by 10.66666 gives l/100km

= 9.375 l/100km.

I have had many e-mail enquiries and one viewer. He came all the way from Manchester. Looked at it. Said it was the best out of four he had viewed and wanted it. Said he would ring me that night on his return home to arrange a bank transfer. Never heard from him again. I had the same with the TVR though. Until a genuine buyer came yesterday and took it away.

If it's any help, I used to get 14 km/l from my c6 z06 in Dubai, currently about 22mpg with no motorway driving at all, just b roads and town driving.

I'd imagine a c5 to be a bit better on fuel than that.
