Top Gear (1978)

Season 22: Episode 2

The switch to lead-free petrol has created a lot of confusion for the ordinary motorist — confusion that now seems to be stalling the growth of sales of unleaded fuel. Tom Boswell seeks to shed light on the introduction of the new high-octane ‘super’ unleaded. As Britain moves closer to Europe, businessmen are less concerned about being seen driving only British cars. Chris Goffey compares three desirable executive saloons from the continent: the Alfa 164, the Saab CD and Lancia’s Thema. Plus, a look at the arcane world of autojumble; and Tiff Needell demonstrates what it’s like to drive a 500hp Ford Sierra.
