At the heart of the 2015-2016 Seat Leon III ST Cupra 2.0 TSI (290 Hp) start/stop was a highly acclaimed 2.0-liter turbocharged inline-four engine, designated EA888 / CJXH. This powerplant, renowned for its robust design and tunability, featured a sophisticated DOHC (Double Overhead Camshaft) valvetrain with four valves per cylinder, totaling 16 valves. Its advanced fuel injection system combined both direct injection and multi-port manifold injection, optimizing fuel delivery across various engine loads for enhanced power and efficiency. A single turbocharger, complemented by an intercooler, ensured a consistent supply of dense air to the engine, contributing to its impressive output. The engine delivered a formidable 290 horsepower, peaking across a broad range from 5900 to 6400 rpm. Equally impressive was its torque output of 258.15 lb.-ft., available from a remarkably low 1700 rpm and sustained up to 5800 rpm. This wide torque band provided exceptional responsiveness and strong acceleration across the rev range. With an engine displacement of 121.07 cubic inches (1984 cm3) and a compression ratio of 9.3:1, the engine achieved a power per liter figure of 146.2 Hp/l, showcasing its high specific output. The inclusion of a Start & Stop System further contributed to fuel efficiency by automatically shutting off the engine during brief stops, restarting seamlessly when the driver is ready to proceed. The engine oil capacity stood at 6.02 US quarts, with a coolant capacity of 10.57 US quarts.

Acceleration and Fuel Economy

The performance figures for the Seat Leon III ST Cupra 2.0 TSI (290 Hp) start/stop underscore its “hot wagon” credentials. It could sprint from 0 to 60 mph in a swift 5.7 seconds, with the 0 to 100 km/h (0-62 mph) benchmark achieved in 6 seconds. The top speed was electronically limited to 155.34 mph (250 km/h), a common practice for performance vehicles in Europe. Despite its impressive performance, the vehicle also demonstrated commendable fuel economy, particularly for its power level. Utilizing gasoline (petrol) as its fuel type, the combined NEDC fuel consumption was rated at 34.6 US mpg (6.8 l/100 km). Urban driving yielded 26.4 US mpg (8.9 l/100 km), while extra-urban cruising improved to 42 US mpg (5.6 l/100 km). Carbon dioxide emissions were 158 g/km, adhering to the stringent Euro 6 emission standard, reflecting SEAT’s commitment to environmental considerations alongside performance. The vehicle’s weight-to-power ratio of 4.7 kg/Hp (212.5 Hp/tonne) and weight-to-torque ratio of 3.9 kg/Nm (256.4 Nm/tonne) further illustrate its favorable power-to-weight distribution, enabling its brisk acceleration and dynamic capabilities.

Design, Ergonomics, and Practicality

Exterior Design and Dimensions

The Seat Leon III ST Cupra 2.0 TSI (290 Hp) start/stop presented a sleek and athletic aesthetic, characteristic of SEAT’s design language during this period. As a station wagon (estate) with five doors and seating for five occupants, it balanced sporting intent with family-friendly practicality. Its dimensions were well-proportioned for the compact segment: a length of 178.86 inches (4543 mm), a width of 71.5 inches (1816 mm), and a height of 56.34 inches (1431 mm). The wheelbase measured 103.58 inches (2631 mm), contributing to both interior space and stable handling. The front track was 60.47 inches (1536 mm), and the rear track was 59.45 inches (1510 mm). The Cupra trim added distinctive styling cues, including larger air intakes, specific bumpers, and unique alloy wheel designs, available in sizes 7.5J x 18 with 225/40 R18 tires or 8J x 19 with 235/35 R19 tires, enhancing both its visual appeal and road presence. The overall design was purposeful, conveying both speed and functionality.

Interior and Cargo Versatility

The interior of the Leon III ST Cupra was designed to be both driver-focused and passenger-friendly. While specific interior features are not detailed in the provided data, SEAT typically equipped its Cupra models with sport seats, a flat-bottom steering wheel, and premium materials to enhance the driving experience. The true highlight of the ST body style, however, was its exceptional cargo versatility. The trunk (boot) space offered a generous minimum of 20.73 cubic feet (587 liters), which could be expanded dramatically to a maximum of 51.91 cubic feet (1470 liters) with the rear seats folded down. This expansive load area made the Cupra ST a highly practical vehicle for hauling luggage, sports equipment, or groceries, effectively combining the performance of a hot hatch with the utility of a larger family car. The kerb weight of the vehicle was 3009.31 lbs. (1365 kg), with a maximum permissible weight of 4343.11 lbs. (1970 kg), allowing for a maximum load of 1333.8 lbs. (605 kg). The fuel tank capacity was 13.21 US gallons (50 liters), providing a decent range between fill-ups, while a maximum roof load of 165.35 lbs. (75 kg) added further versatility for carrying additional gear.

Chassis, Handling, and Safety

Suspension and Braking Systems

The driving dynamics of the Seat Leon III ST Cupra 2.0 TSI (290 Hp) start/stop were significantly enhanced by its well-engineered chassis and suspension setup. The powertrain architecture featured an internal combustion engine driving the front wheels, making it a front-wheel-drive vehicle. Power was transmitted through a precise 6-speed manual transmission, offering an engaging and direct connection between driver and machine. The suspension system was fully independent, a crucial factor for superior ride comfort and handling. At the front, it utilized a McPherson strut design with coil springs and an anti-roll bar, providing excellent body control and steering response. The rear featured an independent multi-link spring suspension, also equipped with a stabilizer bar, which is superior to simpler torsion beam setups often found in compact cars, especially for maintaining wheel alignment and grip during cornering. Braking performance was equally robust, with ventilated discs at both the front and rear axles, ensuring strong, fade-resistant stopping power crucial for a performance vehicle. An Anti-lock Braking System (ABS) was standard, enhancing safety by preventing wheel lock-up during hard braking. The steering system was a rack and pinion type, complemented by electric power steering, which offered precise control and variable assistance, adapting to different driving speeds for optimal feel.

Driving Dynamics

The combination of a powerful engine, a sophisticated independent suspension system, and a precise manual gearbox made the Seat Leon III ST Cupra 2.0 TSI (290 Hp) start/stop a highly engaging vehicle to drive. Its front-wheel-drive layout, coupled with an advanced chassis, allowed for agile handling and responsive cornering, making it a favorite among enthusiasts. The minimum turning circle of 34.45 feet (10.5 meters) indicated good maneuverability for its size, an advantage in urban environments. The Cupra’s dynamic capabilities were further refined by SEAT’s attention to detail in suspension tuning, which provided a firm yet compliant ride, capable of absorbing road imperfections while maintaining composure during spirited driving.
