By the early 2000s, the Rover V8 started to become uncompetitive with other V8 engines in its class. It produced between 80-100 hp less than more modern V8 engines, it was not as fuel-efficient as newer V8s, and used an outdated 16-valve pushrod architecture, while V8 engines made by other luxury automakers used dual overhead-cams and 32 valves. With the switch to the BMW M62 V8 in the 2003 Range Rover, and the switch to Jaguar AJ-V8 engines in the 2005 Land Rover Discovery, the last mass-produced Rover V8 was made in May 2004, after 37 years of production, with the 2004 Land Rover Discovery being the last mass-produced vehicle to use it. The last Rover-branded vehicle that used the Rover V8 was the Rover SD1, which was discontinued in 1986 and replaced by the Rover 800, a rebadged version of the Honda Legend, a vehicle that was co-developed with Honda and Rover Group. It used a 2.7 litre variant of the Honda C engine as its top engine choice. MG Rover Group used a SOHC variant of the 4.6 L Ford Modular V8 engine for the Rover 75 and MG ZT 260 from 2003-2005. The Rover V8 remained with Land Rover when it was sold to Ford by BMW. Although Land Rover has switched to the Jaguar AJ-V8 engine for new applications, they wanted production of the engine to continue, and they arranged for production to restart in Weston-super-Mare under MCT, an engineering and manufacturing company. MCT will continue limited production of the engine for the foreseeable future, supplying engines for aftermarket and replacement use.
