The SEAT Leon III 1.6 TDI (90 hp) is a compact hatchback that was produced between 2012 and 2015. Part of the third generation of the Leon, this model was primarily aimed at the European market, where fuel efficiency and diesel engines were highly favored. While not officially sold in the United States, the Leon represents SEAT’s offering in the competitive C-segment, rivaling vehicles like the Volkswagen Golf, Ford Focus, and Opel Astra. The 1.6 TDI variant specifically targeted buyers seeking economical transportation with reasonable performance.
SEAT Leon III 1.6 TDI: A Detailed Overview
The Leon III marked a significant step forward for SEAT, moving the brand towards a more mature and sophisticated design language. Built on the Volkswagen Group’s MQB platform – shared with models like the Audi A3 and Skoda Octavia – the Leon III offered improved handling, interior quality, and technology compared to its predecessors. The 1.6 TDI model, while not the most powerful in the Leon range, provided a balance between affordability, fuel economy, and everyday usability.
Engine & Performance
The heart of the SEAT Leon III 1.6 TDI is a 1.6-liter, inline-four cylinder diesel engine. This engine, designated CLHB or CXXA, produces 90 horsepower at 2750-4800 rpm and 230 Nm (169.64 lb.-ft.) of torque between 1400-2750 rpm. The engine utilizes a turbocharger with an intercooler to enhance performance and efficiency. A diesel commonrail fuel injection system ensures precise fuel delivery, contributing to both power output and reduced emissions. The engine’s 16.2:1 compression ratio is typical for a diesel engine, maximizing combustion efficiency.
Power is delivered to the front wheels via a five-speed manual transmission. Acceleration from 0 to 100 km/h (0-62 mph) takes 12.6 seconds, while 0 to 60 mph is achieved in approximately 12 seconds. The car has a maximum speed of 178 km/h (110.6 mph). While these figures aren’t particularly sporty, they are adequate for everyday driving and highway cruising. The focus of this engine configuration was clearly on fuel economy, achieving a combined fuel consumption of 4.1 l/100 km (57.4 US mpg or 68.9 UK mpg) and CO2 emissions of 108 g/km, meeting Euro 5 emission standards.
Design & Features
The SEAT Leon III 1.6 TDI is a five-door hatchback, offering a practical and versatile body style. Its exterior design is characterized by sharp lines, a distinctive front grille, and a sloping roofline. The interior is designed with a driver-focused layout, featuring a relatively minimalist dashboard and comfortable seating for five passengers.
Standard features typically included ABS (Anti-lock Braking System), power windows, central locking, and a basic audio system. Higher trim levels offered additional features such as alloy wheels, air conditioning, and a more advanced infotainment system. The trunk (boot) space is a practical 380 liters (13.42 cu. ft.) with the rear seats up, expanding to 1210 liters (42.73 cu. ft.) when the rear seats are folded down. The car’s kerb weight of 1281 kg (2824.12 lbs) contributes to its relatively nimble handling. A particulate filter was included as standard to reduce harmful emissions from the diesel engine.
