I really hate to do this to you Murray but the 7.3 l/100km average showing on my dash equates to just over 38.8 mpg.... that was in 7th gear and you can see my speed and the rpms.... thats the efficiency.... not much higher than an idle..... but, that being said, it doesn't take much of a prolonged push on the throttle to drop that down to 8 mpg.... lol...When you think about the performance potential of these cars the milage you are getting is just short of incredible. In the muscle car era you could pass a lot of cars. You could not pass a gas station.
Impressive numbers. I know I have got over 30 mpg (sorry only number that makes sense to me) with the C5 but there does not seem to be any question that the newer generations have gotten even more efficient.
hey Jeremiad. I am Canadian. I was raised with miles and gallons, much like 99% of the members of this forum. The 38 plus miles per gallon is imperial gallons which we used in Canada from the beginning of time and most of the members can relate to from their past. If this were an American forum, with a majority of American members, I would have talked in American terminology. If I'd have been here at all.My average falls between 8.4 and 9.2, including some spirited sprints. I've seen 7.3 on a few highway trips where I completely behaved. lol.
I can't help but correct you though Ruff..... 7.3L/100km is 32mpg.
The only country in the world that still uses miles is the USA, so your conversion is to US gallons, not UK. Sorry, but I hate it when people exaggerate their mileage to something that just isn't true. It's 3.8L to a gallon, not 4.3.
Nevertheless, getting over 30mpg out of a big V8 engine is stunning. I have a lot of fun surprising people with the mileage indicator on the dash, especially with how my car sounds. No one believes it gets that kind of mileage, but it does.
I guess you're hearing the answer to your question...... That's Canadian mpg....Two things old dogs like me know for certain. We don't learn new tricks (unless it's our girlfriends teaching them) and we don't give a $hit what the "rest-of-the-world" thinks ...!L/100 is the most accurate way to measure your mileage, because there is no argument about units of measure. A liter is a liter, and a meter is a meter, no matter what country you are from.
I just chuckle a bit every time I hear an inflated mpg number and have to ask, "Is that Canadian mpg, or rest-of-the-world mpg?" Even Top Gear converts to US mpg, and given that it is an American standard of measure, it should always be measured in US units of measure. When your dash is telling you 7.3L/100, go ahead and switch to "English" in your options and see what your mpg is.
