Arrow constant travelling speed versus mileage

One's for sure: doing 68 mph gets a much lower mpg than doing 55! Even Gerhard can't beat physics...

Shooting for Guinness World Records one has basically to figure out at which speed a specific car gets the best mileage. With most cars that speed is somewhere between 60 and 90 km/h (37 - 56 mph). Now, european trucks generally travel at 89 km/h (ca. 55 mph, yes they usually exceed their 80 km/h speed limit by 10+ %). Hypermilers would have to travel that speed in order not to disturb traffic flow on the RH lane. Yes, it's a sport and a lot of concentration is needed to shoot for best mileage. It's a sportier way of driving than putting 'the pedal to the metal'.

As Gerhard is generally averaging 75 - 80 km/h on his record drives, his highway speed would be closer to 90 than 110 km/h. Each km/h above 90 will reduce mileage by ca. 1%
