months later, was one of the most popular load carriers in Britain for several years after its launch. In 1986, Austin Rover's holding company BL plc became Rover Group plc and was privatised by selling it to British Aerospace (BAe) in 1988. Plans to replace the Metro with a radical new model, based on the ECV3 research vehicle and aiming for 100 mpg, led to the Austin AR6 of 1984–86, with several prototypes tested and production expected to start before the end of the decade. The desire to lose the Austin name and take Rover "upmarket" led to this project's demise in early 1987. In 1988, the Austin badge was phased out and Austin Rover became the Rover Group from the following year. The Austin cars continued to be manufactured, although they ceased to be Austins. They became "marque-less" in their home market with bonnet badges the same shape as the Rover longship badge but without "Rover" written on them. Instead any badging just showed the model of the car: a Montego of this era, for instance, would have a grille badge simply saying "Montego", while the rear badges just said "Montego" and the engine size/trim level. A revamped Metro was launched in May 1990 and got the new K-series engine. It then became the Rover Metro. Despite sales of both the Maestro and Montego being in decline by 1990, these ranges continued in production until 1994 and never wore a Rover badge on their bonnets in Britain. They were, however, sometimes referred to as "Rovers" in the press and elsewhere. Their place in the Rover range was gradually filled by a new generation of Rover models. Possible revival The rights to the Austin name passed to British Aerospace and then to BMW when each bought the Rover Group. The rights were subsequently sold to MG Rover, created when BMW sold the business. Following MG Rover's collapse and sale, Nanjing Automobile Group owns the Austin name and Austin's historic assembly plant in Longbridge. At the Nanjing International Exhibition in May 2006, Nanjing announced it might use the Austin name on some of the revived MG Rover models, at least in the Chinese market. However, Nanjing is for the moment concentrating on reviving the MG brand. The MG brand is traditionally used for sports cars and Nanjing has no rights to the Rover name, so a revival of the Austin name
