The Australian national consciousness has not taken to the idea of diesel engines very well. People pay lip service to fuel conservation issues and sincerely support many other environmental issues, but when it comes to vehicle performance, the Australian public seems to prefer power over economy. That is why many have become excited about the great features and benefits of the TSI engine for its incredible combination of power and economy.The idea that low emissions can accompany powerful performance is a concept the Australian market can definitely appreciate. Drivers are concerned about fuel costs, but diesel engines have failed to hit the mark with Aussie drivers. The TSI engine, on the other hand, offers low emission rates, runs on regular petrol with outstanding fuel economy, and provides high performance and power when needed. For these reasons, a sports car featuring a TSI engine is a very attractive option. One can reduce operating expenses and maintain a low environmental impact while enjoying tremendous power reserves in a sporty package.The extraordinary success of the TSI motor seems to spring from a revolutionary idea — small engines can be more efficient since they need to carry less overall weight. By running lean and mean and flawlessly integrating two advanced technologies, the TSI has upped the power output of a small engine to the level of performance afforded most sports cars, so designing the engine for high-performance vehicles is the next logical step.The smaller engine size not only maximises capability by carrying less weight, but also reduces the friction that leeches away power. TSI engines have pioneered the procedure of coupling petrol fuel injection with both a turbocharger and supercharger to squeeze out every bit of torque from the fuel/air mixture. The result is incredible power from a small engine at every level of operation. TSI engines deliver maximum torque even at low 1500 or 1750 rpm. Drivers can enjoy the added power over a wide range of vehicle speeds.The engineering advance thus represented has garnered numerous awards and acclaim throughout the motor trade. TSI was named engine of the year in 2006 and 2007. In addition to the twin charger technology, the engine employs a direct shift gearbox, which is semi-automatic for seamless shifts and rocket-like acceleration capability. Drivers will never notice the shift from supercharge to turbocharge. When one touches the gas pedal the engine accelerates remarkably smoothly without any hesitation or jerkiness. The engine performs at championship level even when cold.The engine works well even when driven hard. The engine can rev to 7000 rpm comfortably and deliver 2.5 bar of boost pressure. The type of semi-automatic clutch is often a bit sluggish in some vehicles, but not so with the TSI twin-charged systems. It seems to milk every bit of power from the lower gear before switching smoothly. In town the engines executes smoothly and quietly and is a pleasure to operate, but on the open road it is a powerhouse and great fun to put through its paces.Normal driving produces very low emissions and superior fuel economy on regular petrol. The engine also accrues the benefit of lower tax rates due to its reduced engine capacity. Putting a TSI twin-charged engine in a sports car is a brilliant decision for economy, performance and environmental impact.
