General Motors Research & Development has invented what it claims is an industry-first aluminum welding technology, which it predicts will increase the use of the lightweight metal on future vehicles. The latest fuel economy regulations are forcing automakers to improve efficiency. Simple Newtonian physics explains that the force needed to accelerate a mass decreases with weight reduction, for example, less fuel is needed to move a lighter vehicle – if the weight reduction is not used to increase performance, a traditional industry response.
