With rising oil prices, car manufacturers are opting for powerful small capacity engines

In this day of rising oil prices, fuel efficiency has become an important factor in performance and manufacturers are going for powerful small capacity engines. The 1.8-litre TSI (a term used for a single turbocharger direct injection fuel engine) motor has roots in the VW stables, but is not the same as the one in the Octavia RS. The best part about this motor is that it enables direct fuel injection via electronically controlled high-pressure injectors. This gives precise control over the fuel mixture, better fuel economy and generates more power too.

Apart from this, a turbocharger (a combination of supercharger and turbocharger is also offered in other variants abroad) along with four valves per cylinder and variable valve timing completes the technology arsenal and helps it achieve higher horsepower and exceptional fuel economy figures. The belt-driven supercharger operates at lower engine speeds, with the turbocharger coming in as the engine speed increases.

The result of this is excellent driveability and performance throughout the range with no turbo lag and high maximum torque. The combination of these technologies enables a small capacity engine with a high compression ratio to cruise at part load on high gearing, combining dramatic performance with exceptional fuel consumption for a petrol engine.
