Arguably the most captivating vehicle on display at this week's Auto Shanghai 2009 exhibition is the one-off Mantide supercar. A collaborative effort between famed Italian design house Stile Bertone and Danisi Engineering, the carbon-fiber-intensive Mantide wraps its wind-tunnel honed and ultrasleek (0.25 Cd) bodywork around 2009 Corvette ZR1 mechanicals. Matching a 638-horsepower supercharged LS9 V8 in an aerodynamically optimized package that weighs 220 pounds less than a standard ZR1 yields the expected results: a 0-60 mph time under 3.2 seconds and a top end of 217 mph. The Mantide's purposeful yet sensual lines were directly influenced both by state-of-the-art aerospace designs and the latest in race-car thinking. Although its low nose and unique "flying buttresses" and Kamm-back tail treatment are the most visible elements that contribute to its ability to effortlessly slice through the air, a Formula One-style flat floor and functional rear diffuser element also are critical to increasing the car's total downforce figure by an additional 30 percent and trimming dynamic drag by some 24 percent. Penned by Stile Bertone's design chief, Jason Castriota, the street-legal Mantide has been under development for more than a year.
