What is TSI Engine – benefits Of TSI Engines

TSI stands for “turbocharged straight injection” and was inspired by the technology of Volkswagen’s TDI Clean Diesel and FSI direct fuel injection engines. The engine allows for higher torque at lower RPMs, which means more power with less fuel usage. TSI engines combine direct injection and turbocharging to offer impressive power while still providing incredible fuel efficiency.

turbocharged Stratified Injection (TSi), this engine combines GDI (Gasoline Direct Injection) with Turbocharging and this results in an awesome spread of power. For an instance, you get into the meat of power right at 1500 rpm and this end till 6000 rpm. In fact in some engines, VW has combined Turbocharging, Direct Injection and Variable valve timing altogether making them the most tech laden and most efficient engines in every manner.

Rest drive it to believe it, the 160 bhp Laura TSi could easily eat up anything on wheels under 35 lac (Even entry level Audi and BMW too) except the Passat 2.0 TDi which was simply a hooligan. 0–100 used to get dismissed under 8.5 seconds and speedo used to touch 240 kph on open stretches.

In terms of fuel economy, the 1.8 TSi is’n the king by any ways. It is a sober drunkard like all TSi engines and is very much sensitive to the way you drive. Drive with light foot and you can expect 14–15 kpl. Put the foot down and it will deliver 6–7–8 kpl only.

1.2 TSi which we get to see in Polo GT is also same. I have personally taken over 18 kpl and under 10 kpl from this engine under different driving conditions on the open highways.

Awards for TSI

International Engine of the Year awards

Our pioneering technology has impressed motoring experts from across the world. Our 1.4-litre TSI Twincharger engine has won the 1-litre to 1.4-litre category of the prestigious International Engine of the Year Awards for five years running and was voted the International Engine of the Year and Best Green Engine in 2009.

The jury for this award is made up of 65 motoring journalists from 32 countries. At the 2009 Awards, the jury said: “Volkswagen not only attained an overall victory, but also won the ‘Best Green Engine’ award. This shows that driving fun and fuel efficiency can certainly be unified in one package.”

Dr Rüdiger Szengel, Head of Volkswagen Petrol Engine Development, commented on TSI: “Their combination of reduced displacement, direct injection and intelligent engine boosting enables top dynamic performance while keeping emissions and fuel consumption low. Winning awards in three key categories is really a compliment to our development team. TSI engines are genuine trendsetters.”


You enjoy excellent driveability and outstanding fuel economy. Acceleration is instant, whichever gear you’re in. So overtaking is safer and you can power smoothly up hills with no delay. TSI technology is available on an increasing number of our cars, from Polo to Sharan.
