This car is an exercise in design for the Cadillac brand, meant to exhibit sustainability, and social influence. WTF is not actually what you think it is this time, it actually stands for World Thorium Fuel. Its a Conceptual design by Industrial Designer Loren Kulesus, check out his page on Coroflot. Its basically a car built to last another 100 years on the same fuel source. The fuel source in question is Thorium, I’ve never heard of it personally, so I’ve provided a wikipedia link if you’re interested. Coroflot is an awesome website to promote designers of all types, so I will definitly do a nice feature soon. Maybe i’ll even set up a profile! What do you think of the design?
