We’re heading into the season when many people think about changing their car, for whom there are a few fuel-saving angles worth considering, even if you’re not a confirmed fuel economy fan. Tempting finance deals mean many buyers will choose a brand new car, in face of the better value of a nearly new, or […]

It’s interesting to take a look at driving for economy from a distinctly different angle, and to do this we’ll take a look at the characteristics of the Merlin engine used in the Supermarine Spitfire ñ one of the heroes (along with the pilots and the Hurricane) of the Battle of Britain.

Let us return again to aerodynamics, and how they can significantly affect your fuel economy. The inescapable laws of physics determine the amount of energy required to push a car through the air, which is dependent on the shape and size of the car (so-called ìdragî or air resistance), the density of the air, and […]
