Turbo lag can become increasingly intrusive as engines get smaller. Superchargers are mechanically geared to enhance performance at either low or high engine speeds. The need to reduce CO 2 emissions is leading to downsized engines, heavily boosted by turbo- or supercharging. million today to 12 million by 2016.
