Labeled simply "CROSSOVER" this brushstroke profile of an upcoming concept was released by Infiniti today. Actually, Infiniti called this line drawing a "gesture" of a "new luxury crossover concept" that we'll be seeing at the New York International Auto Show in April. Infiniti even promised that the production version of this luxury crossover concept will be in Infiniti showrooms by the end of 2007. Is it a new FX replacement? It actually looks like a Mazda RX-8 to some of us, and definitely not a four-door. Perhaps it's an altogether new model to go head-to-head with all those crossover coupe offerings coming from the Euro luxury car makers like the the BMW X6 or Land Rover Coupe. Perhaps with all of the leaked photos that came out ahead of the Detroit unveilings, this will be the closest we get to seeing what the mystery vehicle really looks like until April in New York.
