We all know a lighter car use less fuel, goes better and is often better handling. most 10 year old cars are very heavy, take Astra H for instance, the sri coupe weighs 1401kg according to specs. An earlier model Calibra weigh 1280kg. Manufacturers increased the safety by making the cars heavier and now the trend is to start sheading that weight, a new Mazda Mx5 weighs 100kg less than its predecessor.
Have you any good ideas that are economically viable to make your car lighter, legally without compromising safety or comfort?
I was looking at the brake components, they are all solid iron and weigh a lot, then comes wheels and tyres, they weigh 20kg each, seats, exhaust system, battery and so on.
