Autovia Limosuine. (1937-38)
The Autovia engine was created by sticking two Riley 1½Litre engines together, in much the same way as the Nine engine was used in the 8/90. The two blocks were mounted on a common crank, at 90°, while the rest was in traditional Riley style.
The cars were mainly sold as chassis, for outside suppliers to build the bodies - most were built by Mulliners. The two 'standard' bodies were the Saloon and Limosuine, and whilst it is known that not all of the cars were bodied by Mulliners, the only surviving bodies are to the two basic designs.
The name Autovia was used to try and create a new brand - hoping to suceed where the Riley 8/90 failed. However, it was not to be, and after a mere 44 cars were built, Autovia was wound up in a desperate attempt to keep Riley afloat. approximately 9 complete / restorable cars appear to survive, with 2 or 3 chassis also remaining, one of which has been shortened as a special.
