Lots of the examples above are cases where the car came first, so was not named after the aeroplane! e.g. Standard had a Vanguard in production in 1948, 11 years before Vickers flew their Vanguard (unless you reckon the Vickers Type 170 which is a bit specialist!)
Wot about Armstrong-Siddeley aeroplanes then?
Lancaster
Hurricane
Typhoon
Tempest
Whitley
and then they used names for their aeroplane engines that the car industry seemed to like such as:
Jaguar
Lynx (e.g. Riley)
Tiger (Sunbeam)
and Sapphire which A-S used for both car and engine!
