What is an eTSI Volkswagen?
The eTSI with mild hybrid technology is a significant new feature. A starter-alternator provides extra assistance for the engine when starting off and at low speeds. The lithium-ion batteries are charged under braking and while coasting. This achieves a significant reduction in fuel consumption and emissions. Cars labeled as eTSI are equipped with a mild-hybrid drivetrain. This means that the vehicle is powered by a traditional internal combustion engine, which is assisted by an electric motor.

What is the eTSI engine?
Cars labeled as etsi are equipped with a mild-hybrid drivetrain. This means that the vehicle is powered by a traditional internal combustion engine, which is assisted by an electric motor. Tsi vehicles are not capable of running solely on electric power. A car with etsi technology is equipped with a proven combustion tsi engine and a small electric motor functioning as a starter-generator. This electric motor operates either in alternator mode to charge the 48v batteries or in boost mode to assist the combustion engine in powering the vehicle.
Is ETSI better than TSI?
We think the non-hybrid 148hp 1. TSI strikes a better balance between performance and efficiency. It matches the 148hp 1. TSI for torque but costs significantly less to buy new. If you cover a lot of miles. Diesel isn’t for everyone, though, and happily the 148bhp 1. TSI’ mild-hybrid – which is the one fitted to this car and the one that won an award in Towcar of the Year 2025 – does a stellar job of towing a 1,200-1,300kg caravan.
