Seat Leon III ST 1.6 TDI (105 Hp) startstop 4Drive

The Seat Leon III ST 1.6 TDI (105 Hp) start/stop 4Drive, produced between 2014 and 2016, stands as a notable example of a practical and efficient compact station wagon designed primarily for the discerning European market. While the SEAT brand is not officially sold in the United States, this particular iteration of the Leon ST (Sport Tourer) showcases the Volkswagen Group’s engineering prowess applied to a more dynamic and youth-oriented brand. Positioned within the C-segment, this third-generation Leon ST combined a versatile body style with a fuel-efficient diesel powertrain and the added assurance of an all-wheel-drive system, making it an attractive proposition for families and individuals seeking utility without sacrificing driving dynamics or economical operation.

Engine and Performance: The Heart of the Seat Leon III ST 1.6 TDI (105 Hp) start/stop 4Drive

At the core of the Seat Leon III ST 1.6 TDI (105 Hp) start/stop 4Drive lies a robust and highly efficient 1.6-liter (1598 cm³ or 97.52 cu. in.) inline-four cylinder diesel engine, designated with the model code CLHA. This powerplant, featuring a front, transverse layout, delivers a respectable 105 horsepower at a broad range of 3000-4000 revolutions per minute. More critically for a diesel engine, it generates a substantial 184.39 lb.-ft. of torque, available from a low 1500 rpm up to 2750 rpm. This wide torque band ensures responsive acceleration and strong pulling power, particularly beneficial for a family vehicle or when carrying a load.

The engine utilizes a common rail fuel injection system, a hallmark of modern diesel technology, coupled with a turbocharger and intercooler to maximize both power output and fuel efficiency. With a compression ratio of 16.2:1 and four valves per cylinder, the engine operates with precision and refinement. Its power per liter stands at 65.7 Hp/l, reflecting a well-optimized design for its displacement. Performance figures include an acceleration from 0 to 60 mph in a calculated 11.4 seconds, with a maximum speed of 116.2 mph (187 km/h). These numbers indicate a vehicle engineered for steady, confident progress rather than outright speed, perfectly aligning with its practical station wagon brief.

One of the key features enhancing the efficiency of this model is the integrated Start & Stop system, which automatically shuts off the engine when the vehicle is stationary and restarts it when the driver intends to move. This system, combined with a particulate filter to meet stringent emissions standards, significantly contributes to the vehicle’s impressive fuel economy and lower CO2 emissions. The Leon ST 1.6 TDI (105 Hp) start/stop 4Drive boasts a combined fuel consumption of 4.5 liters per 100 kilometers, equating to an excellent 52.3 US mpg. Urban driving yields 42.8 US mpg, while extra-urban conditions can see figures as high as 58.8 US mpg. These figures, alongside CO2 emissions of 119 g/km, underline its Euro 5 emission standard compliance and its commitment to environmental responsibility.

Design, Features, and Drivetrain

The Seat Leon III ST adopted a modern and sharp design language, characterized by crisp lines and a sporty stance, reflecting SEAT’s emphasis on dynamic aesthetics. As a station wagon (or estate, as it’s known in Europe), the vehicle prioritizes practicality and cargo capacity. With five doors and seating for five occupants, it offers ample space for families and their belongings. The design ingeniously balances its utilitarian purpose with an appealing visual presence, distinguishing it from more conventional competitors in its class.

Dimensionally, the Leon ST measures 178.54 inches (4535 mm) in length, 71.5 inches (1816 mm) in width, and 57.13 inches (1451 mm) in height. Its wheelbase of 103.78 inches (2636 mm) contributes to a stable ride and a spacious cabin. The front track is 60.98 inches (1549 mm), and the rear track is 59.84 inches (1520 mm), providing a solid footprint on the road. The vehicle’s kerb weight is 3207.73 lbs (1455 kg), while its maximum permissible weight is 4365.15 lbs (1980 kg), allowing for a substantial maximum load of 1157.43 lbs (525 kg).

Cargo versatility is a strong suit of the Leon ST. The trunk (boot) offers a minimum capacity of 20.73 cubic feet (587 liters), which can be expanded to a cavernous 51.91 cubic feet (1470 liters) with the rear seats folded down, making it highly adaptable for various hauling needs, from groceries to sports equipment or luggage for a long road trip. The vehicle’s assisting systems include ABS (Anti-lock braking system), a fundamental safety feature that helps maintain steering control during emergency braking.

Drivetrain and Chassis Dynamics

A distinctive feature of this particular model is its “4Drive” system, signifying an all-wheel-drive (AWD) powertrain. This system provides enhanced traction and stability, particularly beneficial in adverse weather conditions or on unpaved roads, offering a greater sense of security and control. Power is transmitted to all four wheels via a precise 6-speed manual transmission, which allows the driver to fully engage with the vehicle and optimize power delivery for different driving scenarios. The manual gearbox is a testament to the European market’s continued appreciation for driver involvement.

The steering system utilizes a rack and pinion setup, known for its direct feel and responsiveness, contributing to the Leon ST’s reputation for agile handling. This combination of a responsive diesel engine, a slick manual transmission, and an all-wheel-drive system ensures a balanced and engaging driving experience, characteristic of cars built on the Volkswagen Group’s MQB platform, which underpinned many of its contemporary compact vehicles.
