Of course, there’s no DVD player in the Nano (and no radio, either, in the basic model); but its innovations (which have garnered 34 patents) are not merely the result of doing away with frills (including power brakes, air conditioning, and side-view mirrors). Reducing the use of steel by inventing an aluminium engine; increasing space by moving the wheels to the edge of the chassis; and relying on a modular design that enables the car to be assembled from kits proved conclusively that you could do more with less.
