Positioned transversely at the front of the vehicle, the engine was equipped with a turbocharger, a key element in delivering both power and torque that belied its relatively modest displacement for an executive car.

The engine produced 118 horsepower at a conservative 4200 rpm, which was a respectable output for a diesel engine of its era. More importantly for real-world driving, it generated a substantial 197.67 lb.-ft. of torque, peaking at a low 2100 rpm. This ample low-end torque was instrumental in providing strong acceleration from a standstill and effortless cruising, characteristics highly valued in a vehicle of this class. The power density was rated at 47.2 HP per liter, indicating a well-engineered and efficient unit.

Fuel delivery was managed by a precombustion chamber injection system, a common and reliable technology for diesel engines in the 1990s, known for its smoother operation compared to direct injection systems of the time, albeit slightly less efficient than later common-rail designs. The engine featured a high compression ratio of 22.1:1, typical for a diesel, and utilized two valves per cylinder, optimizing the balance between performance and fuel economy. With an engine oil capacity of 6.4 US quarts and a coolant capacity of 8.45 US quarts, the engine was designed for durability and ease of maintenance.

Performance figures for the 825 D/SD (XS) were competitive for a diesel sedan of its time. It could accelerate from 0 to 60 mph in a calculated 10.6 seconds, making it capable of merging onto highways and overtaking with confidence. The maximum speed was rated at 118.06 mph (190 km/h), more than sufficient for European autobahns and motorways. Crucially, its fuel economy was a major selling point, achieving an impressive combined figure of 36.8 US mpg (6.4 liters per 100 km). This efficiency, combined with a generous 17.96 US gallon fuel tank, provided a significant cruising range, ideal for long-distance travel. Power was sent to the front wheels via a smooth-shifting 5-speed manual transmission, offering direct driver engagement and contributing to the overall fuel efficiency.

Design and Features

The Rover 800 825 D/SD (XS) (118 Hp) maintained the dignified and somewhat conservative styling that characterized the 800 series. As a four-door sedan with seating for five, it exuded an air of understated elegance, typical of European executive cars of its era. The design featured clean lines and a commanding presence, reflecting Rover’s aspiration to offer a premium product. Its dimensions were substantial, with an overall length of 192.2 inches, a width of 68.11 inches, and a height of 54.84 inches. A generous wheelbase of 108.9 inches contributed significantly to both the car’s stable ride and its spacious interior.

Inside, the 800 series was known for its comfortable cabin, often trimmed with quality materials that reflected its executive positioning.
