30. Aston Martin One-77
At a time of the looming death of gigantic engines, Aston Martin whipped up one of its most creative projects with the One-77 when it did. Although there still might be hope for the massive internal combustion engine yet, gearheads have appluaded Aston for the incredibly beautiful One-77, of which only 77 one-off vehicles were produced. We're also happy that it was fitted with a 7.3-liter V12 that makes 750 horsepower and is the world's most powerful naturally aspirated engine.
