60 MPG over 175 miles is possible.. Well nearly!

Tourist · 9th December 2018, 19:03

Hello all,

I've just got back from a trip from Fulbourn (near Cambridge) to Poole (in Dorset - I'd recommend it to anyone!) and back - it was a lovely drive with the Rover on top form. I also saw a lot of 75s on my travels, which was very encouraging.

I filled up at Canford Heath Asda and reset the trip computer just after lunch and the traffic condiitons were such that although I went M27, M3, M25 and M11, it was pretty much a steady 60 mph all the way so I decided to see if I could beat my previous MPG figure over a longish distance.

By the time I got off the M25, it was reading an average of 61.4 MPG and slightly faster traffic conditions on the M11 brought that down to 60.1 by the time I got home, however I'm pretty pleased with that. My car under reads consumption slightly so that's most likely actually about 57 to 58 MPG in reality but I think that on the right day I can probably achieve the magic 60 ;-)

Here's the evidence, apologies for the lines on the display. I like that in the second pic the range is 612 miles, with 175 already on the clock. That's a bit ambitious, but I regurlary get over 600 miles from a tankfull. What a superb car!

Magnificent! Unfortunately I'm at 44.1 even with a new maf

Certainly more realistic

60MPG is cloud cuckoo land in any R40

The most I have ever had is 600miles from brimming the tank to deliberately running it out.

Doing a brim to brim test over 400 miles i did get 57.1 but it was mostly good A roads or motorways.

The diesels do around 48 mpg at best. Only according to the manufacturer though, I mean, what do they know?

I assume you are quoting the combined figure?

34.9/64.2/48.7 UK MPG urban/extra-urban/combined ... So a steady run on mostly dual or motorway would qualify as extra urban i would guess. Only according to the manufacturer though, I mean, what do they know?

Mine has achieved 60 or very close to 60 on a long motorway run (mostly flat) with the cruise control set at 70. I believe the 160 remap improves fuel consumption in these conditions.

The manufacturer figures no longer apply if it isn't standard.

When I had a diesel ZT the maximum I ever achieved was 47 mpg on a steady run driving like a saint. On average late 30s was the norm.
