Petrol is not diesel, so not sure how your datapoint relates. Which petrol cars get more than 39mpg?

Also, were diesel cars only getting those high mpg due to cheating the emissions limits? I never saw them in the US.

My car gets over 50 mpg and that's from odometer and fuel volume, not from a spec sheet.

Diesel goes a bit further than petrol on a volume basis but not that much. Maybe it's just due to smaller US gallons and a cruisy commute.

A colleague of mine gets 65 mpg, fwiw, and it's not a hybrid.

Also the emissions thing wasn't about fuel economy, but about NOx emissions.

Because you guys like huge heavy cars full of unnecessary toys inside.

Lots of hybrid sedans, eg Prius, Corolla, Ioniq, Insight Granted I think the only non-hybrid ICE getting 39mpg or better is the Mitsubishi Mirage.

I don't believe so. Diesel is more efficient partially because diesel engines have been around longer (so have more improvements).

They have a much higher compression ratio and also aren’t pumping across a partially closed throttle plate virtually all of the time.
