The SEAT Leon III SC 1.2 TSI (110 Hp) start/stop DSG is a compact, three-door coupe produced by the Spanish automobile manufacturer SEAT between 2014 and 2016. Part of the third generation of the Leon, the SC (Sport Coupe) variant offered a more youthful and sporty aesthetic compared to the five-door hatchback. While SEAT is now a subsidiary of the Volkswagen Group, and the Leon shares its platform with models like the Volkswagen Golf and Audi A3, the Leon historically served as a more affordable and design-focused offering within the European market. This particular model, powered by a 1.2-liter turbocharged gasoline engine, was aimed at buyers seeking a balance of fuel efficiency, performance, and style.
SEAT Leon III SC: Overview and Market Positioning
The Leon III SC represented a significant step forward for SEAT in terms of design and technology. Launched as a direct competitor to cars like the Ford Focus, Opel Astra, and Peugeot 308, the Leon SC distinguished itself with its sharp lines, modern interior, and a range of efficient engine options. The “SC” designation indicated the coupe body style, featuring a sloping roofline and three doors, appealing to a demographic prioritizing a sportier look. In Europe, where it was primarily sold, the Leon competed on value and design, offering a compelling alternative to more established brands. The inclusion of features like the Start/Stop system and DSG (Direct-Shift Gearbox) transmission highlighted SEAT’s commitment to fuel economy and driving convenience.
Engine & Performance
The heart of the SEAT Leon III SC 1.2 TSI is a 1.2-liter, inline-four cylinder gasoline engine equipped with a turbocharger and direct fuel injection. This engine produces 110 horsepower at 4,600-5,600 rpm and 175 Nm (129.07 lb.-ft.) of torque between 1,400 and 4,000 rpm. The turbocharger provides a noticeable boost in power, enhancing responsiveness and providing adequate acceleration for everyday driving. Paired with a seven-speed DSG dual-clutch automatic transmission, the Leon SC delivers smooth and quick gear changes, contributing to a more engaging driving experience. Performance figures include a 0-100 km/h (0-62 mph) acceleration time of 10 seconds and a 0-60 mph time of 9.5 seconds, with a maximum speed of 191 km/h (118.68 mph). Fuel economy is a strong point, with combined fuel consumption rated at 4.8 l/100 km (49 US mpg or 58.9 UK mpg), and CO2 emissions of 112 g/km, meeting Euro 6 emission standards.
Design & Features
The SEAT Leon III SC boasts a distinctive coupe silhouette, characterized by its sleek roofline and three-door configuration. The exterior design incorporates sharp lines and a sporty front fascia, giving the car a modern and dynamic appearance. Inside, the cabin is designed with a focus on functionality and driver comfort. The interior features a clean dashboard layout, supportive seats, and quality materials. The SC model offers seating for five passengers, although rear passenger space is somewhat limited due to the sloping roofline. Standard features typically included ABS (Anti-lock Braking System), air conditioning, power windows, and a basic audio system. The Start/Stop system, a key feature of this model, automatically shuts off the engine when the vehicle is stationary to reduce fuel consumption and emissions. The DSG transmission further enhances the driving experience by providing seamless gear changes and improved fuel efficiency. Trunk space is respectable for a coupe, offering 380 liters (13.42 cu. ft.) with the rear seats up and expanding to 1,150 liters (40.61 cu. ft.) with the rear seats folded down.
