The upshot of the piece is that the car tested produced 30% more CO2 cruising at 80mph instead of 70mph.
That's fine for that specific car, under those specific conditions ... but not for all cars.
E.g. my PD with 6-speed box is more economical cruising at 85 than at 70 ... I've proved it many, many times on long m-way journeys.
This is a combination of aerodynamics, gearing, and the higher cruising speed means less time spent being baulked by lorries etc in lanes 1 and 2.
Next thing will be a blanket 55mph speed limit for "environmental" reasons.
