Beneath the 1957 Maserati 2000 Gran Sport Spyder’s elegant open coachwork lay Maserati’s advanced 2-liter DOHC inline six-cylinder engine, derived directly from the marque’s competition program. The aluminum-headed powerplant featured twin ignition plugs per cylinder and triple Weber carburetors, allowing the compact six to breathe freely and produce roughly 150 horsepower, an impressive figure for a naturally aspirated two-liter engine of the period.
