The SEAT Leon IV 1.5 TGI (130 Hp) is a compact hatchback produced by the Spanish automobile manufacturer SEAT from April 2021 to January 2023. Representing the fourth generation of the Leon, this model is particularly notable for its availability with a Compressed Natural Gas (CNG) powertrain, offering an alternative fuel option within the competitive European small family car segment. While SEAT vehicles are not officially sold in the United States, the Leon is a significant model in Europe, often competing with vehicles like the Volkswagen Golf, Opel Astra, and Ford Focus. The 1.5 TGI variant aimed to provide a more environmentally friendly option, leveraging the lower emissions associated with CNG compared to traditional gasoline.

The Leon IV represents a substantial evolution in SEAT’s lineup, built upon the Volkswagen Group’s MQB Evo platform. This platform allows for greater flexibility in powertrain options and improved structural rigidity. The 1.5 TGI model specifically caters to markets with established CNG infrastructure, offering drivers a reduced carbon footprint and potential cost savings on fuel. The vehicle is a five-door hatchback, designed to balance practicality, efficiency, and a modern aesthetic. It’s positioned as a versatile vehicle suitable for both urban commuting and longer journeys.
