06 — TEST VEHICLE
1965 CHEVROLET CORVAIR MONZA
1965 Corvair Demo Build.
Vehicle configuration and test information.
Our California test car pairs a previous-generation motor with an upgraded 1966 Saginaw four-speed manual and three pedals. Eight battery modules provide 37.6 kWh: six in the front trunk and two in the rear engine bay. It runs the Formosa EV app.
Measurement and build notes
Before conversion: 2,722 lb and 37:63 front/rear. After conversion: 3,179 lb and 44:56 front/rear. Corner weights measured July 10, 2026. Range is an estimate for this vehicle; vehicle configuration and driving conditions affect range.
Why a Corvair?
GM explored electric Corvairs in the 1960s. The 1966 Electrovair II used a silver-zinc battery split between the front trunk and rear engine compartment; it remained a research car. Our 1965 Corvair carries modern battery modules in those same areas and keeps a four-speed manual and three pedals. Formosa EV is not affiliated with General Motors.
