Concepts of a "car that never was" developed by Lotus and Toyota are among a collection of items belonging to a Norwich car designer who died recently.

Oliver Winterbottom, who designed cars for Lotus, Jaguar and TVR from the 1970s to the 1990s, died in 2020 at the age of 76 and now fans of the cars he created will be able to get their hands on his collection of books, models and blueprints.

Mr Winterbottom led the Lotus Toyota X100 project, the last car overseen by Colin Chapman in 1982, which saw the two companies develop a two-seater roadster, but the project stalled when Mr Chapman died and was never made commercially available.

Plans and concepts of the X100 as well as other vehicles Mr Winterbottom, from Wymondham, designed are included in the lots.
