Infiniti's dramatic Triant concept is seem again here in Chicago following its world debut in Detroit. The luxurious sports coupe concept features a long, elegant hood, sharply sloped windshield and hatchback, and oversize wheelwells stuffed with large wheels and tires. Wide, power-assisted gullwing doors grant access to the 2+2 cabin, with an innovative sliding rear seatback that can nearly double the cargo area. High-tech headlights "guide" the light beam around turns with the aid of digital mapping data and GPS technology, while inside voice-based controls operate some cockpit features such as phone, navigation, and audio systems.
