The Rover 400 is a British compact family car from the Rover Group line. Produced in collaboration with Honda from 1990 to 2005 in the UK, Birmingham. In total, 3 generations of the model were released. The 1st generation of the car was based on Honda Domani / Civic. After 2000, the designation of the 400th series of the model was changed to 45th as a sign of independence of production – without the participation of third-party manufacturers. In general, the 400th has good dynamic performance.

The range of Rover 400 engines includes several types of gasoline and diesel engines with good dynamics. All engines are very demanding on fuel quality. The 400 Series chassis is a balance of comfort and excellent handling thanks to the multi-link design and suspension settings that are softer than the Civic.
The Rover 400 was offered with 11 engines between 1990 and 1999 (8 petrol, 3 diesel). Displacement ranges from 1.4 to 2.0 liters, power output from 75 to 200 hp. All of them use a timing belt. 4 are turbocharged. The longest rated lifespan belongs to the Peugeot XUD7TE (about 350,000 km).
