I’ve got a 2019 R with 4000 miles on it.
I get 28mpg in eco mode doing the daily commute to work, which is about 15 miles, that pretty much all urban driving.
I find that it stays around that the whole time in eco mode, it drops on A roads and motorways over a certain speed!
In race mode, it drops to about 20-23 MPG.
Also, I tried a tank of super unleaded, and the MPG actually dropped! What’s that all about??
you're supposed to be using super unleaded anyway in an R aren't you? Why are you driving in Eco mode? And after one tank you complain about a drop in consumption? Was the weather colder when you tried the tank of Super?
The R will happily run on regular unleaded, like all modern fuel injection engines.
I’m driving it in Eco just to make it a better proposition to use for daily commute. To be honest there’s no chance of going fast round here in the rush hour anyway!
The conditions were exactly the same, I used a couple of tanks of unleaded, then put a tank of super in. Just found it strange MPG seemed to drop by a few units. Not seen this before, always got more mileage out using super.
Maybe I’ll try another tank.
It is also on very low miles, so presume that economy will increase as the mileage goes up!
