Jaguar will premiere its C-XF concept at NAIAS 2007, the company announces. The four-door sport sedan, which “blends design purity with unmistakable dynamism,” the C-XF is a clear indication of the design direction that the next generations of Jaguar saloons will take, the British automaker said. The exterior design is contemporary but pays homage to classic Jaguars. The four-seat cabin uses traditional materials, but fashioned in new and contemporary ways. The powertrain is the supercharged V8 with a six-speed automatic that delivers quick manual gear changes thanks to the Jaguar Sequential Shift System.
