Very distinctive 711 was the second Formula 1 car produced by Macrh Engineering. The design was radically changed comparing to the 1970 March 701. The 711 had side-mounted radiators and inboard front brakes, although been moved outboard later in the season. But the most distinguished feature of the car was aerodynamics developed by Frank Costin. The very large elliptic front wing described as the Spitfire (for its shape) or “tea-tray” (for its elevation from the car), high cockpit sides merging into a head fairing, full engine cover and rear airfoil make the car very aerodynamically efficient. STP Corporation disbanded its own team, but continued to support the works team. Ronnie Peterson was signed as the principal driver of STP March Racing Team. Other woks cars were provided to Andrea de Adamich, Nanni Galli and Alex Soler-Roig. Soler-Roig, 40 years old racing driver from Barcelona, started at the first 5 rounds of the Championship, but did not reach the finish line at all of his races. At French Grand Prix at Circuit Paul Ricard Soler-Roig had retired very early due to oil pump failure. It was his last race for March.
