Or you could swap in the new 2.8 Mini Duramax

We're pulling down over 30 MPG at 70mph in a stock 2017 full size chevy van at about 7500lbs. Engine rpm is 1500 at 70 mph in eighth gear and has plenty of power.

Probably wouldn't be unlike my Freightliner sans trailer. Riding that torque once the turbo spools is wicked fun.

Corvette instant MPG

A buddy of mine had a convertible corvette with an automatic MPG readout. He drove it like a maniac. I looked over at the readout while he was going about 80 and it was reading 35mpg. Go figure. with top down. Lighweight body, alloy wheels, efficient streamlining. I do not know if it had a belly pan.

Those also tend to read a bit high, but 5% would be less than 2 MPG.

Steering & braking are what matter. No one makes a vehicle to deal with such a wide variance in vehicle speeds amongst traffic. It’s just a dumb pursuit.

Especially as it ignores what is the basis of “need”? There isn’t any.

EM to cut costs? Fine. It’s only finesse of what already makes a good driver. But leave that out and it’s justification for a lie (“me, Me, ME!”).

Grow up.

Its more of a mental exercice at the moment. It is an interesting conversation topic. But if you do crazy miles at higher speeds like that one guy with the hybrid who was doing more than 500 miles a week in a hybrid on the motorway it could be interesting data.

Yesterday i drove a friends bmw 320d accross cities and the mpg was good even though i was going a bit fast. 5.9l/100km.

At what speed?

With my 1200cc motorbike I can get 4.4L/100km @ 80 kph

Or 10L/100km @ 180kph.
