Crazy MPG in petrol B5

Dr Dave · Sep 22, 2022

With fuel prices at crazy levels in the UK I decided to see what I could get out of my 2020 XC90 B5 Petrol on a recent motorway trip.

So - 106 miles, a steady 65mph on pilot assist, premium unleaded fuel returned 45.5mpg ! Driving journal included below.

So if you’re not in a rush, backing off 5mph can get you pretty incredible economy for a 2.5 tonne car!

Just a reminder to us in the USA, UK gallons are larger than US Gallons, so that is almost 38MPG here as a comparison.
Still, very very good!

I’ve observed similar gains in our T8 on long trips. Holding at 60mph and I get mid to high 30s on ICE. T8 Pure is great for around town but for highway/long trips using “Hold” for saving battery for later is much like driving a regular Hybrid (nonPHEV).

That's impressive and pretty much similar to what I get from my 2022 B5 Diesel. Typical motorway consumption for me is 46mpg with a best of 50mpg

Yes, maintaining a constant slower speed in the highest possible gear can deliver some impressive mpg numbers.
