The Seat Leon III ST 2.0 TDI (150 Hp) start/stop DSG represents a compelling blend of practicality, efficiency, and dynamic styling within the European compact segment. Produced by the Spanish automaker SEAT, a member of the Volkswagen Group, the Leon III ST (Sport Tourer, or station wagon) was a crucial offering in markets where versatile family vehicles are highly valued. This particular variant, manufactured between 2014 and 2016, distinguished itself with its robust diesel powertrain, advanced automatic transmission, and an array of features aimed at maximizing both driving pleasure and everyday usability. While SEAT vehicles are not typically sold in the United States, their engineering and market positioning offer a fascinating insight into the European automotive landscape, where the Leon often competed against segment leaders like the Volkswagen Golf Variant and Skoda Octavia Combi, offering a sportier design language.
Engine and Performance: The Heart of the Seat Leon III ST 2.0 TDI (150 Hp) start/stop DSG
At the core of this model lies a highly regarded 2.0-liter TDI (Turbocharged Direct Injection) diesel engine, a powerplant synonymous with efficiency and robust torque delivery across the Volkswagen Group. This inline four-cylinder engine, identified by codes such as CRBC, CKFC, CRLB, or CRMB, is transversely mounted at the front and features a sophisticated common rail fuel injection system, complemented by a turbocharger and intercooler for optimal air management and power output. It generates a respectable 150 horsepower at a practical rev range of 3500-4000 rpm, translating to a power-per-liter figure of 76.2 Hp/l, showcasing its efficient design. More notably for a diesel, it produces a substantial 236.02 lb.-ft. of torque, available broadly from 1750 to 3000 rpm. This wide torque band is critical for effortless acceleration and flexible driving, especially when carrying a full load or navigating varied terrain.
Power is channeled to the front wheels via a sophisticated 6-speed automatic DSG (Direct Shift Gearbox) transmission. This dual-clutch unit is renowned for its rapid and smooth gear changes, offering a seamless driving experience that balances performance with fuel economy. The combination of the potent TDI engine and the efficient DSG gearbox allows the Leon III ST to accelerate from 0 to 60 mph in a brisk 8.2 seconds, with a top speed reaching 131.11 mph. These figures underline its capability as a competent tourer, capable of comfortable highway cruising and confident overtaking maneuvers.
Efficiency is a significant hallmark of the 2.0 TDI engine. The vehicle boasts impressive fuel consumption figures, achieving an estimated 43.6 US mpg in urban conditions and an even more remarkable 57.4 US mpg on the extra-urban cycle. The combined fuel economy stands at an excellent 52.3 US mpg, making it an economical choice for long-distance travel. These figures are aided by the integrated Start & Stop System, which automatically shuts off the engine when the vehicle is stationary, reducing fuel waste and emissions in city traffic. Furthermore, the inclusion of a particulate filter ensures the vehicle meets the stringent Euro 5 emission standard, producing 119 g/km of CO2, reflecting a commitment to environmental responsibility during its production years. The engine’s design also accounts for maintenance, with an oil capacity of 4.6 liters (4.86 US quarts) and a coolant capacity of 8 liters (8.45 US quarts).
Design and Features
The Seat Leon III ST distinguishes itself with a sleek and dynamic design that belies its practical station wagon body type. Measuring 178.54 inches in length, 71.5 inches in width, and 57.13 inches in height, the Leon ST strikes an appealing balance between compact maneuverability and generous interior space. Its wheelbase of 103.78 inches contributes to a stable ride and ample legroom for passengers. With a front track of 60.98 inches and a rear track of 59.84 inches, the vehicle maintains a planted stance, enhancing its road holding capabilities.
As a 5-door station wagon, the Leon III ST is designed for versatility, comfortably accommodating five occupants. The interior is characterized by functional design and quality materials, typical of Volkswagen Group products. Practicality is a strong suit, with a minimum trunk (boot) space of 20.73 cubic feet, which expands significantly to a cavernous 51.91 cubic feet with the rear seats folded down. This makes it an ideal choice for families, active individuals, or anyone requiring substantial cargo capacity for luggage, sports equipment, or everyday hauls.
The vehicle’s kerb weight of 3042.38 lbs. is commendably low for its class, contributing to both its agile handling and fuel efficiency. With a maximum permissible weight of 4299.01 lbs., it offers a generous maximum load capacity of 1256.63 lbs. The drivetrain architecture is straightforward and proven: the internal combustion engine drives the front wheels, providing predictable handling and excellent traction in most conditions. The steering system utilizes a responsive rack and pinion setup, ensuring direct feedback to the driver. In terms of safety, the Leon III ST comes equipped with essential assisting systems like ABS (Anti-lock Braking System), a foundational feature for maintaining control during emergency braking maneuvers, reinforcing its commitment to occupant safety and driver confidence.
