The Seat Leon TGI is currently available with a 1.4-liter turbocharged petrol four, but the automaker has just unveiled a brand new mill that’s using compressed natural gas (CNG).
Called the Leon TGI Evo, it has a turbocharged 1.5-liter, four-cylinder, direct-injected unit, which is based on the petrol TSI engine of the same capacity.
Seat says that it has Miller cycle combustion, new-gen variable turbine geometry turbocharging system and an advanced stop/start system. Joining them are new segments in the chrome-nickel covered pistons, reinforced valve seats that increase wear resistance and raised valves that improve gas circulation.

All of these work together to help the engine meet the demands of running on CNG. The total output is 130 PS (128 hp / 96 kW) and 200 Nm (148 lb-ft) of torque and the engine is paired to either a six-speed manual or a dual-clutch seven-speed gearbox.
The new Leon TGI Evo has three CNG tanks with a larger capacity than before. The range of the car in CNG mode is 500 km (311 miles), to which an additional 150 km (93 miles) can be added by switching to petrol.
Seat didn’t announce any pricing details, equipment or market availability of the Leon TGI Evo yet, but said that it will be available in the FR, Xcellence and Style grades.
