Ford's supercar stable has been empty since the departure of the limited-run Ford GT in 2006, but that's about to end with the introduction of the next-generation Ford GT announced at the 2015 North American International Auto Show in Detroit. The new GT is a radical street car with heavy inspiration from Ford's involvement in racing.Strong, lightweight carbon fiber is used extensively throughout the GT as the cockpit's primary construction material and used heavily elsewhere. Ford expects the GT to have one of the best power-to-weight ratios of any production car thanks to the use of carbon fiber paired with the more than 600-horsepower, twin-turbocharged V-6, which is Ford's most powerful EcoBoost engine to date.
