Audi R8 V8 & V10 Fuel consumption comparison

[330 CNM]

Hi all,
Would like to know what the 'real world' fuel consumption comparison between the R8 V8 and V10... is there much difference??.
Hoping to purchase an R8 Spyder at some point over the coming year and just trying to gain an understanding of the realistic fuel consumption figures for the two engines.
I'm currently favouring the V10 version and keen to understand a bit more about the fuel side of things.
Also, do both these engines run OK on'normal' unleaded fuel or is it a must that they use 'super' unleaded fuel.

Thanks in advance for your help.

Super unleaded only, V8 will do mid 20s if you behave yourself, V10 will not.

Unless you're really mean you'll be smiling too much to care in either.

Thanks for quick response DrG... much appreciated.

Done 29k miles daily use in my V8 and never reset the trip. Average mpg is 16.6.

the joy you get from the v10 will over ride your concerns about the mpg difference

My poky wee 2.0T 4-pot runs like a pig on 95RON fuel.

I certainly wouldn't be feeding it to a V8/V10...

FSI motors like super unleaded, particularly the earlier 2.0Ts. Surprisingly big difference isn't it!

Huge difference, only had to run my 2.0T on 95 once and it was horrible....

On a good run in my V8 i sometimes get 28mpg. This does drop significantly when hooning or around town.

I use normal unleaded, its fine.

Are you really worried about this on a £80K car?? My V8 R8 varies wildly on consumption dependant on journey as bad as 8mpg up to high 20's for constant motorway.....

Thanks to all for your helpful replies.

Depends on your annual mileage.

I usually average 15k miles a year, with my R8 at 16mpg in comparison to my previous 997GT3 at 22mpg, the R8 is using an extra 250 gallons of fuel a year, whch is an extra £1,500 pa. A reasonable factor in the running costs.

I'm 8 years late on this topic but considering an R8 vs a 996 turbo and it's a very useful comparison. Thanks. Interestingly I get about 2-3 mpg less (in most scenarios) out of my current 996 3.6 C2 than I did from my 996 3.6 Turbo, which is a heavier car and permanent 4wd
