Zero to sixty-two in 3.4 seconds? Check. 780 horsepower? Check. Zero Emissions? Check. The Jaguar C-X75 ($TBA) is a new concept vehicle designed to celebrate the British car maker's 75th anniversary, and as such is packed with high-end gear like two 96-horsepower micro gas turbines that help recharge a plug-in lithium-ion battery, which in turns powers four 195-horsepower electric motors, one for each wheel. Other highlights include three high-res screens for driver information, an aluminum body with swan doors, and a futuristic design that screams "I will never see a commercial release."
