One of the most beautiful cars ever built, the lightweight powerful Alfa Romeo 33 Stradale also holds the record of being the most expensive new car sold in the US of its time at around $17,000. Initially as many as three of the extremely rare Stradale came to North America, but now only one remains on the continent. The car modeled for Forza Motorsport 4 is part of one of the greatest private collections of Italian cars in the world. These cars were ahead of their time, using butterfly-style doors, large wrap-around glass, twin-spark ignition, dual-overhead cams, a six-speed Coletti transmission, and plenty of lightweight magnesium parts. As you start the two-liter V8 engine, it doesn’t take long to realize the powerplant is only inches behind your head. With an RPM redline of 9,500--outrageous for 1968--you hear a symphony of sound from rumble to scream.
