Using a turbocharger allows more power to be produced from a smaller capacity engine with lower fuel consumption and, consequently lower CO2 exhaust emissions. Achieving this balance requires careful engineering and we have succeeded in applying the technology to a new range of highly efficient petrol engines. These smaller engines weigh less than their larger, naturally aspirated equivalents, which also has a positive impact on efficiency.
We have also developed more efficient direct-injection turbodiesel technology to produce a new family of diesel engines that achieve exceptional thermal efficiency together with higher levels of torque and fuel economy. Our new advanced diesel combustion and after-treatment system also strongly reduces NOx emissions, helping protect air quality.
