21 MPG in a Cerb

[Mr Cerbera]

Now, I have achieved AMAZING mpg fogures when I have driven from Lux to the UK and have been shocked by consumption figures at TrackDays
BUT
When I found this YouTube vid, I was spleased to hear his results.

Hope that you are too

Yeah, that's probably around what I get.

When I toured France last year, I'd do a rough calc at every fill and it would be between later teens & early 20s.

I get 24mpg on a cruise/travel...22mpg around town.
I did get 27mpg on a gentle cruise down to Spa last time as the support van with all the camping gear/beer could only go about 70mph and we stuck with it for support

On a run i get high 20's i guess 28mpg would be about right.

I did a fairly quich run to Sps a year or so ago, cruising around 130 and more at times, still returned well into 20's but had a great 2hours.

If I'm out and mixing driving enthusiastically from time to time with normal pootling about, I'll get about 20-21mpg. On long runs, I've had 27mpg out of it pretty regularly, and if I'm really really behaving I can inch it up a bit more, to 28/29. It has been freshly sorted by Chesterfield's finest engine mapper. I say it every time but Joolz is a genius,

The cerb is more economical than my big diesel van when I'm just pootling about from place to place. The van thinks I occasionally get 30mpg, but it isn't accurate, it's just a number on the display. Factor in the fuel price difference and fuel consumption, and sometimes it would be fractionally cheaper (pence) to take the TVR instead.

My guess is less weight to get shoved off the line and up to speed, easier freewheeling in top gear, less mechanical drag overall, much lower cd, all adding up to make it really not that bad.

Of course having a tear up I've been well down in to single figures

All the Europe trips I’ve done including several 3k mile round trips to the south of Spain have averaged between 24 and 25mpg, mostly cruising at 80ish. Also mapped by Joolz. The comparatively high gear ratio (eg 3200rpm at 80mph) is not great for economy, ICEs are most efficient under load. A sixth gear or lower final drive ratio would likely improve the mpg on those long journeys.
