Seat Leon III ST 2.0 TDI (150 Hp) startstop

The Seat Leon III ST 2.0 TDI (150 Hp) start/stop represents a compelling offering from the Spanish automaker, Seat, a prominent member of the Volkswagen Group primarily catering to the European market. Launched in 2015 as part of the third generation Leon lineup, this particular variant, the ST (Sport Tourer or station wagon), was designed to combine the brand’s characteristic sporty aesthetics and dynamic driving experience with enhanced practicality. Positioned within the highly competitive compact segment, the Leon III ST aimed to attract buyers seeking a versatile family vehicle that didn’t compromise on engaging performance or fuel efficiency. Its production run from 2015 to 2016 highlights a specific iteration within the broader third-generation lifecycle, emphasizing a period where diesel powertrains, particularly those with advanced emission controls like the Euro 6 standard and start/stop technology, were at the forefront of automotive innovation for efficiency and environmental compliance in Europe.

Engineering and Performance of the Seat Leon III ST 2.0 TDI (150 Hp) start/stop

At the heart of the Seat Leon III ST 2.0 TDI (150 Hp) start/stop lies a robust and efficient 2.0-liter TDI (Turbocharged Direct Injection) diesel engine, a testament to the Volkswagen Group’s expertise in diesel powertrain development. This inline four-cylinder unit, with an engine displacement of 1968 cm³ (120.09 cu. in.), is mounted transversally at the front, driving the front wheels. It delivers a respectable 150 horsepower at a range of 3500-4000 rpm, translating to a power output of 76.2 HP per liter, indicative of its modern, high-efficiency design. More crucially for everyday driving, the engine generates a substantial 250.77 lb.-ft. of torque, available across a broad and accessible band from 1750-3000 rpm. This ample torque at lower engine speeds ensures strong pulling power and effortless acceleration, particularly beneficial for a station wagon often used for family duties or long-distance travel.

The engine benefits from a sophisticated common rail fuel injection system, which precisely controls fuel delivery for optimal combustion, contributing to both power output and fuel economy. Augmenting its performance is a turbocharger coupled with an intercooler, a setup that forces more air into the engine, significantly boosting power and torque delivery while maintaining efficiency. The compression ratio stands at 16:1, typical for a modern diesel engine, balancing performance with thermodynamic efficiency. Each cylinder features four valves, enhancing gas flow for improved breathing and overall engine responsiveness. Furthermore, the engine is equipped with advanced systems designed to minimize its environmental footprint and improve efficiency. The Start & Stop System automatically shuts off the engine when the vehicle is stationary, such as at traffic lights, and restarts it seamlessly when the driver intends to move. This technology, combined with a particulate filter, helps the vehicle meet stringent Euro 6 emission standards, a critical factor for vehicle registration and usage in European cities during its production years.

Paired with a crisp-shifting 6-speed manual transmission, the powertrain architecture of the Leon III ST 2.0 TDI (150 Hp) start/stop delivers a compelling blend of performance and driver engagement. The vehicle accelerates from 0 to 60 mph in a brisk 8.2 seconds, making it a capable performer for merging onto highways or overtaking. Its maximum speed of 133.59 mph further underscores its competence as a long-distance cruiser. The weight-to-power ratio of 9 kg/Hp (111.1 Hp/tonne) and a weight-to-torque ratio of 4 kg/Nm (251.9 Nm/tonne) highlight the engine’s ability to move the vehicle’s 2976.24 lbs. (kerb weight) with authority, ensuring a dynamic yet composed driving experience.

Design and Features of the Seat Leon III ST

The Seat Leon III ST, with its station wagon (estate) body type, embodies a fusion of Seat’s distinctive design language and practical utility. Measuring 178.54 inches in length, 71.5 inches in width, and 57.13 inches in height, with a wheelbase of 103.78 inches, the vehicle strikes a balance between a compact footprint and generous interior space. The design is characterized by sharp lines, angular headlights, and a distinctive grille, all contributing to a sporty and contemporary aesthetic that set it apart in its segment. Despite its utilitarian body style, the Leon ST manages to retain the athletic stance and visual dynamism of its hatchback sibling, reflecting Seat’s commitment to injecting passion into its mainstream models.

Functionality is paramount in a station wagon, and the Leon III ST excels in this regard. It comfortably accommodates five occupants across its five seats, accessible via five doors. The trunk (boot) space is particularly impressive, offering a minimum of 20.73 cu. ft. (587 liters) with all seats in place, expanding dramatically to a cavernous 51.91 cu. ft. (1470 liters) when the rear seats are folded down. This expansive cargo capacity makes it an ideal choice for families, individuals with active lifestyles, or those requiring significant hauling capability without resorting to a larger SUV. The maximum load capacity of 1256.63 lbs. further enhances its versatility, allowing for substantial cargo or passenger loads.

In terms of driving dynamics and safety, the Leon III ST is well-equipped for its era. The drivetrain architecture, as mentioned, features an Internal Combustion Engine (ICE) driving the front wheels, a common and efficient layout for this class of vehicle. Steering is managed by a precise rack and pinion system, offering responsive feedback and control. Safety is bolstered by standard assisting systems such as ABS (Anti-lock Braking System), which helps maintain steering control during emergency braking maneuvers. While specific interior features beyond seating and door count are not detailed, a 2015 model in the European market would typically include modern conveniences such as air conditioning, power windows, an infotainment system, and a range of passive safety features like multiple airbags and a reinforced passenger cell, all designed to enhance occupant protection and comfort.
