The first is a twin-turbocharged V-8, code-named “Voodoo,” which displaces between 5.0 and 5.5 liters and, most intriguingly, has a “flat-plane” or 180-degree crankshaft, as Ferrari has used in its V-8s since 1973. This configuration, also found in the late Lotus Esprit V-8, is akin to connecting two four-cylinder banks to a common crankshaft. Flat cranks theoretically improve power, throttle response, and the soundtrack at the expense of greater vibration. This EcoBoost V-8 will produce between 550 and 600 horses. It will power a Shelby GT350–branded model that eventually will take over from the GT500, as Ford is desperate to discontinue that car’s costly and thirsty Trinity.
