Seat Leon III ST 1.6 TDI (105 Hp) startstop DSG

The Seat Leon III ST 1.6 TDI (105 Hp) start/stop DSG represents a compelling blend of practicality, efficiency, and dynamic styling, positioning itself as a strong contender in Europe’s highly competitive compact station wagon segment. Produced between 2014 and 2015, this particular iteration of the third-generation Leon Sport Tourer (ST) showcased Seat’s commitment to offering versatile family vehicles with a distinctive Spanish flair, all built upon the robust and proven Volkswagen Group MQB platform. While the Seat brand is not officially sold in the United States, its vehicles, like the Leon, play a crucial role in the European automotive landscape, providing a more emotionally charged alternative to its German counterparts within the VW Group, such as the Volkswagen Golf Variant or Skoda Octavia Combi. This specific model, with its efficient 1.6-liter TDI diesel engine and advanced DSG automatic transmission, was engineered to appeal to drivers prioritizing low running costs, substantial cargo capacity, and a responsive driving experience for both urban commutes and long-distance travel.

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

At the core of the 2014-2015 Seat Leon III ST 1.6 TDI (105 Hp) start/stop DSG lies a sophisticated 1.6-liter (1598 cm³) inline four-cylinder TDI (Turbocharged Direct Injection) diesel engine, designated with the code CLHA. This powertrain is a testament to the Volkswagen Group’s expertise in diesel technology, delivering a commendable balance of power and exceptional fuel economy. The engine generates 105 horsepower at a versatile rev range of 3000-4000 rpm, a figure that provides ample motivation for daily driving and highway cruising. More significantly, it produces a robust 184.39 lb.-ft. of torque, available from a low 1500 rpm up to 2750 rpm. This broad torque band is a hallmark of modern diesel engines, ensuring strong acceleration from a standstill and flexible in-gear performance, making overtakes effortless even when the vehicle is fully laden.

Power is efficiently managed by a 7-speed DSG (Direct Shift Gearbox) automatic transmission. This dual-clutch unit is renowned for its rapid, seamless gear changes, which not only contribute to a sportier driving feel but also play a critical role in optimizing fuel consumption and reducing emissions. The DSG’s ability to pre-select the next gear means there’s virtually no interruption in power delivery, enhancing both comfort and efficiency. Further bolstering its environmental credentials and economy is the integrated Start & Stop System, which automatically shuts off the engine when the vehicle is stationary, such as at traffic lights, and restarts it instantly when the driver presses the accelerator. This system, along with a standard particulate filter, helps the Leon III ST 1.6 TDI meet the Euro 5 emission standard, reflecting its commitment to minimizing its environmental footprint.

Performance figures for the Seat Leon III ST 1.6 TDI are respectable for its class and intended purpose. The vehicle can accelerate from 0 to 60 mph in an estimated 10.5 seconds, with a top speed reaching 118.68 mph. These figures underscore its capability as a practical yet capable family hauler. Where the 1.6 TDI truly shines, however, is in its fuel efficiency. The combined fuel economy is an impressive 60.3 US mpg (3.9 l/100 km), while extra-urban driving can see figures as high as 67.2 US mpg (3.5 l/100 km). Even in urban settings, it achieves a remarkable 51.1 US mpg (4.6 l/100 km). These low consumption rates, coupled with CO2 emissions of just 102 g/km, made the Leon III ST 1.6 TDI an exceptionally economical choice for European drivers facing high fuel prices and stringent emission regulations.

Design and Features: Practicality Meets Dynamic Style

The Seat Leon III ST, or Sport Tourer, embodies a design philosophy that successfully marries the practicality of a station wagon with Seat’s characteristic sporty aesthetics. Its body type is explicitly a station wagon (estate), featuring five doors and comfortable seating for five occupants, making it an ideal choice for families or individuals requiring significant cargo flexibility. The exterior design, penned under the direction of Alejandro Mesonero-Romanos, is characterized by sharp lines, taut surfaces, and distinctive LED daytime running lights (where fitted), giving it a more aggressive and athletic stance compared to some of its segment rivals. The overall length of 178.54 inches (4535 mm), width of 71.5 inches (1816 mm), and height of 57.13 inches (1451 mm) contribute to a well-proportioned and grounded appearance, while the 103.78-inch (2636 mm) wheelbase ensures a stable ride and generous interior space.

Inside, the Leon III ST prioritizes ergonomics and functionality, typical for a vehicle aimed at the European family market. The cabin design is clean and modern, with logical control layouts and quality materials that were competitive for its segment during its production years. A key highlight of the ST variant is its exceptional cargo capacity. With the rear seats in place, the trunk offers a substantial 20.73 cubic feet (587 liters) of space, which expands to an enormous 51.91 cubic feet (1470 liters) when the rear seats are folded down. This cavernous load area, combined with a low loading sill, makes the Leon ST incredibly versatile for carrying luggage, sports equipment, or even furniture.

Beyond its spacious interior, the Leon III ST 1.6 TDI also came equipped with a range of features aimed at enhancing comfort, convenience, and safety. Standard assisting systems included ABS (Anti-lock Braking System), a fundamental safety feature ensuring stability during emergency braking. The steering system utilized a precise rack and pinion setup, providing responsive and engaging handling characteristic of Seat vehicles. While specific infotainment and connectivity features would vary by trim level, the 2014-2015 model year vehicles typically offered options such as touchscreen displays, Bluetooth connectivity, and climate control, all designed to make journeys more enjoyable. The front-wheel-drive architecture, combined with a carefully tuned suspension (front track 60.98 in/1549 mm, rear track 59.84 in/1520 mm), ensured predictable handling and a comfortable ride, perfectly suited for the diverse road conditions found across Europe.
