The first TFSI engine was based on the 2.0 FSI - the Volkswagen naturally aspirated engine with direct injection. They just added a turbocharger and called it TFSI. It was mainly used for Audi, so from that time they started using this name for Audi turbocharged engines. The first TSI engine was made from a simple 1.4-liter engine.
This is largely thanks to a normally aspirated 1.6-litre four-cylinder engine and manual gearbox, where the rest of the range use a 1.0 litre three-cylinder engine, blessed with turbo-charging. Even with a capacity 2.0 of litres, also force fed, the GTi remains more efficient, with a combined cycle of 5.9 l/100km and 134 g/km of CO 2 emissions.
An international panel comprised of leading journalists gave the VW/Audi 1.0 TSI engine its highly anticipated award. The experts assessed engines in 12 categories for 2018’s pool of engines to choose from, with the 1.0 TSI beating out stiff competition in its cubic under 1.0-liter capacity class.
Unless there's a discretionary change the driver has made, VW should simply shut up and honor their warranty with a proper full scale replacement. As GTO and other mods keep pointing out, European diesels tend to be more reliable than petrol motors. If this 1.0 TSi ghost catches fire, VW will rue their decision of dropping diesels even more.
