The 10 worst engines in Formula 1 history!

#9 Hart 415T, 4 cylinder in-line turbo 1.5L (63 GP, 28 points, 3 podiums)

In the early 1980’s, delving into turbocharger technology was a titanic challenge for major constructors such as Renault, Ferrari and BMW let alone a modest artisan like Brian Hart. Associated with Toleman in F2, the Brit followed the team in its move up to Formula 1 in 1981. He penned the under-powered and fragile 415T that suffered from massive turbo-lag. The inaugural season was a debacle. Fortunately with time it improved and nearly took a historic victory at Monaco in 1984 in the hands of Ayrton Senna.
