The Rover 400 Series, and later the Rover 45, are a series of small family cars that were produced by the British manufacturer Rover from 1990 to 2005. The cars were co-developed as part of Rover's collaboration with Honda. The first-generation 400 was based on the Honda Concerto, and the Mark II 400 (later the Rover 45) was based on the Honda Domani/Civic. Honda petrol engines were used in some Rover models, while the market competitive Rover L-series diesel engine was used from the mid-1990s in Hondas, before they designed their own diesel engine. Rover 400 (R8; 1990–1998) The original 400 Series, launched in 1990 as a four-door saloon, was a saloon version of the second-generation Rover 200 Series hatchback, both sharing the codename R8 during development. The 200 Series had been launched six months earlier. Like the 200, the model was designed in collaboration with Honda (who produced the corresponding designed for Europe Concerto model) and both models would share production lines at Rover's Longbridge facility. It used the same core structure and mechanicals as the Honda, but the rear-end redesign of the glasshouse and body were unique to Rover. Interior trim and electrical architecture were all shared with the R8 Rover 200. An estate — or station wagon — version was subsequently developed by Rover Special Products. Badged as the Rover 400 Tourer, this remained in production alongside the second-generation 400 until 1998, as no estate version of the latter car was built. Many of the 400 Tourers were exported to Japan. The R8 Rover 200 and 400 were the first applications of Rover's K-series family of engines (appearing in 1.4 L (1,396 cc) twin-cam 16-valve form). The 1.6 L (1,590 cc) version used either a Honda D16A6 and D16Z2 SOHC or D16A8 DOHC powerplant, while the 2.0 L M-series unit from the 800 Series followed soon afterwards (1991) in the sportier versions. The Rover-engined models drove the front wheels via jointly developed Peugeot/Rover R65 gearboxes (1.4 litre) and Rover PG1 for the 1.6- and 2.0-litre versions. The Rover 420 GSI turbo and GSI Sport turbo, produced in limited numbers, were equipped with the turbocharged 197 bhp (147 kW) Rover T-series engine. Also available were two PSA (non-electronically controlled Lucas CAV injection pumps) Indirect injection diesel engines, with the choice of naturally aspirated 1.9-litre XUD9 or turbocharged 1.8 XUD7T engines. These engines were installed instead of the non-electronically
