Bruce McLaren’s first sports prototype was the M1A. The team’s first self-designed car, the M1A was another simple space-frame design featuring the Oldsmobile V8 engine via a Hewland transaxle.
Frank Nichols’ Elva Cars was already building its own highly successful sports racers, and he expressed an interest in the new McLaren prototype. The result was an agreement for Trojan (Elva’s parent company) to build a production version: the McLaren-Elva, 24 of which were completed.
For 1965, the design was refined as the M1B.
