The SEAT León III 1.4 TSI (122 Hp) start/stop is a front-wheel-drive hatchback that was produced between 2012 and 2014. Part of the third generation of the León, this model was primarily aimed at the European market, offering a blend of fuel efficiency, practicality, and a relatively sporty driving experience. The León, as a whole, occupies the compact car segment, competing with vehicles like the Volkswagen Golf, Ford Focus, and Opel Astra. While SEAT is a Spanish automobile manufacturer, it has been a subsidiary of the Volkswagen Group since 1986, benefiting from shared platforms and technologies.
SEAT León III 1.4 TSI: Overview and Market Position
The third-generation León represented a significant step forward for SEAT in terms of design, build quality, and technology. Launched in 2012, it moved away from the more rounded styling of its predecessor and adopted a sharper, more angular aesthetic. The 1.4 TSI variant, equipped with a turbocharged gasoline engine and start/stop technology, was a key offering in the lineup, appealing to buyers seeking a balance between performance and economy. In Europe, the León was positioned as a more stylish and driver-focused alternative to the more mainstream Volkswagen Golf, leveraging SEAT’s brand identity.
Engine & Performance
The SEAT León III 1.4 TSI is powered by a 1.4-liter, inline-four cylinder turbocharged gasoline engine, designated CMBA. This engine produces 122 horsepower at 5000-6000 rpm and 200 Nm (147.51 lb.-ft.) of torque between 1400 and 4000 rpm. The engine features direct fuel injection and an intercooler to enhance performance and efficiency. Power is delivered to the front wheels through a six-speed manual transmission. Acceleration from 0 to 100 km/h (0-62 mph) takes 9.3 seconds, while 0 to 60 mph is achieved in approximately 8.8 seconds. The vehicle has a maximum speed of 202 km/h (125.52 mph). The engine’s power-to-weight ratio is 9.4 kg/Hp, and the torque-to-weight ratio is 5.7 kg/Nm, contributing to a responsive driving experience. The inclusion of a Start & Stop system further enhances fuel economy in urban driving conditions.
Design & Features
The SEAT León III is a five-door hatchback with a practical and spacious interior. The design emphasizes sharp lines and a dynamic profile. The interior is well-appointed for its class, with a focus on ergonomics and functionality. Standard features typically included air conditioning, power windows, central locking, and an audio system. Safety features, crucial for modern vehicles, included ABS (Anti-lock Braking System) and driver/passenger airbags. The vehicle’s kerb weight of 1149 kg (2533.11 lbs) contributes to its agility. Trunk space is a useful 380 liters (13.42 cu. ft.), providing ample room for luggage and everyday items. The León’s dimensions – 4263 mm (167.83 in) in length, 1816 mm (71.5 in) in width, and 1459 mm (57.44 in) in height – position it squarely within the compact hatchback segment.
