6. Alfa Romeo Tipo 33 Stradale
Tipo 33 Stradale is one of Alfa Romeo’s and generally one of industry’s rarest production cars – being produced in no more than 18 copies. In true Italian fashion, Tipo 33 Stradale was a handsome, curvaceous automobile which weighted less than 1,550 pounds. That was possible due to slightly smaller powertrain than supercars of the time usually had. 2.0L V8’s 230 horses were routed toward Tipo 33 Stradale’s rear midsection through a 6-speed manual gearbox. Top speed was stuck at 160 mph, and light Alfa needed 5.5 seconds in order to reach 60 mph.
