2010 MT Cars have 3 trip computers - Same as the previous cars there is trip 1 and trip 2, then there is what LR calls Auto-trip. Auto trip is quite clever as it measures your average MPG, ave speed and trip distance on a journey by journey basis ie from start-up to switch off. Additionally there is also an instantaneous MPG. On 2010 these can also be converted to metric by changing a choice in the TFT dash menus..................... I used to use trip A to be "over the life of the car" and trip B as the tankful to tankful but with the average per journey now I don't bother resetting either trips A or B. On my next trip south (a nearly 500 mile drive) I will also run the numbers through my own spreadsheet (it's been lying dormant for the last year or so!) and see what the car does on a brim to brim basis and see what the B trip does for the same distance. I learned long ago that car-makers fuel computers always make the car seem to be more economical than it really is, my RRS's were generally 2mpg less fuel efficient by my spreadsheet compared to the trip computer over the same distance.

When I'm driving I don't hang about or drive with any special technique BUT I do try to drive at a speed that is as fast as I can without using the brakes and I try to use the cruise control as much as possible.Not having the adaptive cruise that I had on the RRS is a bind as that was quite brilliant and seems to be much more progressive at applying engine power than the conventional one on the TDV8 FFRR's which seems to throw the throttle wide open as soon as you click resume or the + button. I also drive at the speed limit of the road I am on - OK it might seem pipe and slippers stuff but it doesn't waste fuel! BUT I do like a blast when it is a suitable road for doing it....................... in 32 years of driving I haven't yet got a speeding ticket, even when I had a TVR I managed to avoid one! 2018 Mini Countryman Cooper S E All4 PHEV in Melting Silver - it’s whisper quiet in EV and polluter modes

I managed to break the 40mpg barrier once on a long trip from St Albans to Birmingham and back - fortunately for me I only needed to go round a couple of roundabouts and spent the rest of the time trundling along at about 60. I even had the air-con off - but that was because I thought the light was 'on' to warn the aircon was off It was a very dull journey.

That said I regularly exceed 30 odd. This morning I got 37.4 from St Albans to Cambridge including traffic and all the rounabouts the A505 has to offer. Cruised at about 60 again where I could though, and the air-con was on this time!

It's a shame the max range the system will show is 621 miles - I have managed to do over 150 miles on a tank and still had 621 range showing (first journey above)

Around town and hills crucifies the range though - my normal average to a tank is about 27 - better than the last car (Merc CL) which got 28mpg at best, 18 usual and single figures if I was having fun

Considering I got an overall of 24.9 in my 5.0 litre SC V8 ....... what are you guys doing in your diesels

A/C on or off - makes NO difference when you are pumping 500+ bhp In fact makes no odds on any engine over 200bhp tbh

Not much town driving?, that's great economy

I get about 380 miles out of a tank on a 4.4 BMW engine works out about 17.5 MPG.

Current TDV8 returns around 23 mpg normal commuter driving, managed 27 mpg high speed 300 mile motorway run S Wales to S Yorks No body told me there would be days like these
