Alfa Romeo New York Taxi

The Alfa Romeo New York Taxi is a concept car, which was designed by Italdesign sometime in 1976, at the invitation of New York Museum of Modern Art. The concept was designed under guidelines from the Museum of Modern Art to produce one cleaner, more efficient taxi. It featured the wheelbase of and could seat five. 
It also featured its own flat floor space to store wheelchairs, storage under the seats and sliding doors on both sides, being one of the first cars to have them. It is based on the front wheel drive running gear of the van of the Alfa Romeo F12, including the 1.3 litre petrol engine and an independent suspension in both the front and rear. 
Some of the design principles which were explored with the "New York Taxi" were expanded upon with the Lancia Megagamma, which was one less boxy more streamlined prototype that gave form to the modern multi purpose vehicle (MPV).
