The 10 worst engines in Formula 1 history!

#8 Alfa Romeo 415T, 4 cylinder in-line turbo 1.5L (0 GP, 0 points, 0 podiums)

Another four-cylinder disaster. Following the dismantling of its race team, Alfa Romeo wanted to make its official return to F1 in1987 as engine supplier to Ligier. But just a few weeks before the start of the season, René Arnoux made incendiary remarks in the media concerning the pitiful performance of the Gianni Tonti designed quattro cilindri. The carmaker’s top brass terminated the contract immediately and Ligier had to hastily fit Megatron, or rather rebadged BMW engines, into its JS29.
