I will keep going. Appendix A of the report makes for very interesting reading. For the ordinary layperson out there, when we look at the different types of cars, we see that a small petrol car is most efficient when it is doing approximately 60 km/h. A medium-sized petrol car is best when it is doing approximately 70 km/h. A large petrol car, interestingly, is better when it is doing 80 km/h. A small diesel car is better when it is doing 70 km/h, a medium-sized diesel car when it is doing 70 km/h and a large diesel car when it is doing 70 km/h. Then, it is very interesting that hybrids are highly efficient at 50 km/h. Small, medium and large hybrids and, then again, electric vehicles are all best when doing 50 km/h.

What is an LGV?
