Driving anywhere at 76mph is going to eat any fuel unless you’re slipstreaming other traffic. Reduce your speed to 66mph and see if you notice a difference. Fact is over a decade of driving hundreds of miles a day as a field engineer has taught me, driving around fast, accelerating hard and speeding does not get you there quicker. It’s a cliche but slow and steady wins the race, not dangerously slow of course but sticking to speed limits, driving a little under, time junctions to maximise regen, using right regen level, all these eco driving tactics all add up. Gotta say I’ve lost count if the times I’ve been doing 60 on a B road and some numpty comes flying past and when you get to the next roundabout they’re right in front of you they got there seconds earlier. I wish I could go back and slap myself when I was in my 20s LOL I’m no expert and I still drive like a fool from time to time but tbh I rarely speed anymore because it’s not worth the effort and worry of getting caught.
I’ll second that!
I used to be a 70+ driver until my wife went on a speed awareness course.
On the motorway I now tend to set the cruise control to drive at 64-66mph and I’ve found that my journey times are identical (or better sometimes) than when I drove like a loon. And yes – now I’m a bit slower on the minor roads you do seem to catch up with those who put their foot down.
