#6 Ilmor LH10, V10 3.5L (32 GP, 12 points, 0 podiums)
Ilmor Engineering, whose kingpin Mario Illien was until not long ago an advisor for Renault Sport F1, enjoyed a fruitful collaboration with Mercedes in Formula 1. But the Brixworth-based company went it alone before being approached by the German giant. It was a long road to hoe with Leyton House (March) and Tyrrell scoring a mere handful of points in 1991 and 1992. While it had an evolution of the English V10, it was a lot worse for Pacific two years later, which on more than one occasion suffered the humiliation of not qualifying.
