Further, there is increasing interest among stakeholders in exploring the benefits of higher octane fuels that would lead to higher compression ratios which would lead to more efficient engines and reduced fuel consumption. One significant trend is engine downsizing coupled with turbocharging. The pressurized intake air allows a turbocharged engine to produce more power compared with a naturally aspirated engine of the same size.

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 Rotrak solution overcomes this constraint by connecting the supercharger to the engine by a compact variable drive, allowing efficient operation across the whole engine speed range. The need to reduce CO 2 emissions is leading to downsized engines, heavily boosted by turbo- or supercharging.
