What does the TSI lettering on the back of Volkswagen cars mean?
1 Answers
Volkswagen's TSI lettering stands for: T refers to Twincharging (dual charging), S refers to Stratified, and I refers to Injection. TSI represents the combined application of twincharging and stratified direct injection technology. Twincharging refers to the combination of a turbocharger and a supercharger. The characteristic of turbocharging is that after the turbo engages, the engine's air intake efficiency increases, allowing the engine to deliver greater power. The supercharger effectively compensates for the turbo lag of turbocharging, as it can provide boost pressure to the engine right from idle speed. The Sagitar 280TSI is a model of the Volkswagen Sagitar, equipped with a 1.4T turbocharged inline four-cylinder engine, delivering 150 horsepower. It features a 7-speed dual-clutch transmission, achieving a 0-100 km/h acceleration time of just 9.3 seconds.
