The SEAT León III ST (facelift 2016) 1.5 TGI (130 Hp) DSG is a compact station wagon produced by the Spanish automobile manufacturer SEAT from 2018 to 2020. As part of the third generation of the León, the ST (SportTourer) variant offered increased practicality and cargo space compared to the hatchback model. This particular version is notable for its bi-fuel capability, running on both gasoline and Compressed Natural Gas (CNG), making it a relatively environmentally conscious option within its segment, particularly in European markets where CNG infrastructure is more developed. The León, in general, is a crucial model for SEAT, representing a significant portion of their sales volume and competing directly with vehicles like the Volkswagen Golf, Ford Focus, and Peugeot 308.
SEAT León III ST 1.5 TGI: An Overview
The facelifted León III, introduced in 2016, brought styling updates, improved technology, and refined engine options. The 1.5 TGI model specifically caters to drivers seeking lower running costs and reduced emissions. While not officially sold in the United States, the León is a popular choice in Europe, known for its blend of practicality, driving dynamics, and value. The TGI designation signifies SEAT’s commitment to alternative fuel vehicles, offering a bridge between traditional gasoline engines and fully electric options.
Engine & Performance
The heart of the León ST 1.5 TGI is a 1.5-liter inline four-cylinder turbocharged engine. This engine is designed to run primarily on CNG, with gasoline serving as a backup fuel source when CNG is unavailable or when additional power is required. Producing 130 horsepower at 5000-6000 rpm and 200 Nm (148 lb-ft) of torque between 1400-4000 rpm, the engine delivers adequate performance for everyday driving. Acceleration from 0 to 100 km/h (0-62 mph) takes approximately 10 seconds, and 0-60 mph is achieved in around 9.5 seconds. The engine features direct fuel injection and a compression ratio of 12.5:1, optimizing combustion efficiency. The engine’s power-to-weight ratio is 100.1 Hp/tonne, and the torque-to-weight ratio is 154 Nm/tonne. The engine is paired with a 7-speed dual-clutch transmission (DSG), providing smooth and rapid gear changes. Fuel economy on CNG is impressive, ranging from 3.5 to 3.7 kg/100 km combined, resulting in CO2 emissions of 95-98 g/km, meeting Euro 6 emission standards.
Design & Features
The SEAT León III ST is a five-door station wagon, offering a practical and versatile body style. The facelifted model features a more aggressive front fascia, redesigned headlights, and updated interior trim. The ST variant boasts a generous 482-liter (17.02 cu. ft.) trunk space, expandable by folding down the rear seats. Inside, the cabin is well-appointed with a focus on functionality and modern design. Standard features typically include air conditioning, a touchscreen infotainment system, and various driver-assistance systems like ABS. Safety features are a priority, with the León ST equipped with multiple airbags, electronic stability control, and traction control. The vehicle’s dimensions are 4549 mm (179.09 in) in length, 1816 mm (71.5 in) in width, and 1454 mm (57.24 in) in height. The wheelbase measures 2636 mm (103.78 in). The kerb weight is 1299 kg (2863.8 lbs), with a maximum permissible weight of 1880 kg (4144.69 lbs).
