This lovely little Alfa Tipo 33/TT12 (from RMi Wood and Chief Wiggum) was the hot Group 5 ticket in 1975, with its Carlo Chiti-designed flat-12 pumping 500-odd horsepower @ 11K and drivers like Lafitte, Pescarolo, Brambilla, Mass, Merzario and Derek Bell. It dominated the manufacturer's world championship that year, winning 7 of the 8 races. Still a blast to drive. Spoiler alert: it loves revs as much as Ferrari's flat-12. Ten laps at Mugello.
