RS6 real world range

[ImmortanJon]

My record was a 420-mile round trip from Devon to Heathrow and back (after dropping 80kg of passenger/luggage off at LHR) via M5-M4-M25. This equated to 31mpg getting home with about 10 litres left in the tank (assuming the tank is 75L which I believe the FL model is).

This was driving 60-70mph in clear traffic and dry weather and I was trying to set a fuel record so smooth accelerations etc. I have found that driving using cruise control (I have standard, not adaptive) yields better fuel economy than manual throttle modulation as it seems to keep the engine in 4-cylinder mode for more of the time.

Suffice to say this was one of the more boring drives I have done, but I did still manage to dish out a quick lesson to a cheeky S3 who was challenging me at one point.

Long term average since purchase is 22 mpg last time I looked. Not a car one buys for fuel economy, but when driven sensibly it is not bad given it’s size and power.

Good luck with the purchase. You will not regret it.

If you can stretch to the RS6 Performance you will get better economy. It seems strange as it gives an extra 50 odd bhp but I guess the engine management is different. Had one for 3 months and found it was a better car all-round. Managed high 20s and often 30s (unheard of in a RS6).

Happy hunting and good luck.
