If you think Infiniti's Coupe Concept bears more than a passing resemblance to the G35 coupe, that's because it presages the next-generation G35 coupe and sedan, which are due out later this year. While the exterior and interior styling provide a good preview of the production cars, there is also a layer of show-car glitz here. Don't expect the LED headlights, the pop-up flush door handles, or the side-view cameras to make production. The Coupe Concept's paddle shifters will be a new feature on the next-generation G35, but we're less certain about some of the more exotic interior features, such as the full-length glass roof, the speakers integrated into the headrests, and the purple instrument lighting.
