Learning from Tata's Nano

The innovations of the $2,500 car carry important lessons for Western executives

by John Hagel and John Seely Brown

The announcement last month by Tata Motors of its newest car, the Nano, was revealing on many levels. The announcement generated extensive coverage and commentary, but just about everyone missed the Nano's real significance, which goes far beyond the car itself.

But, O.K., let's start with the car itself—particularly the price. At about $2,500 retail, the Nano is the most inexpensive car in the world. Its closest competitor, the Maruti 800, made in India by Maruti Udyog, sells for roughly twice as much. To put this in perspective, the price of the entire Nano car is roughly equivalent to the price of a DVD player option in a luxury Western car. The low price point has left other auto companies scrambling to catch up.

Thinking Outside the Patent Box

How could Tata Motors make a car so inexpensively? It started by looking at everything from scratch, applying what some analysts have described as "Gandhian engineering" principles—deep frugality with a willingness to challenge conventional wisdom. A lot of features that Western consumers take for granted—air conditioning, power brakes, radios, etc.—are missing from the entry-level model.

More fundamentally, the engineers worked to do more with less. The car is smaller in overall dimensions than the Maruti, but it offers about 20% more seating capacity as a result of design choices such as putting the wheels at the extreme edges of the car. The Nano is also much lighter than comparable models as a result of efforts to reduce the amount of steel in the car (including the use of an aluminum engine) and the use of lightweight steel where possible. The car currently meets all Indian emission, pollution, and safety standards, though it only attains a maximum speed of about 65 mph. The fuel efficiency is attractive—50 miles to the gallon.

Hearing all this, many Western executives doubt that this new car represents real innovation. Too often, when they think of innovation, they focus on product innovation using breakthrough technologies; often, specifically, on patents. Tata Motors has filed for 34 patents associated with the design of the Nano, which contrasts with the roughly 280 patents awarded to General Motors (GM) every year. Admittedly that figure tallies all of GM's research efforts, but if innovation is measured only in terms of patents, no wonder the Nano is not of much interest to Western executives. Measuring progress solely by patent creation misses a key dimension of innovation: Some of the most valuable innovations take existing, patented components and remix them in ways that more effectively serve the needs of large numbers of customers.

A Modular Design Revolution

But even this broader perspective fails to capture other significant dimensions of innovation. In fact, Tata Motors itself did not draw a lot of attention to what is perhaps the most innovative aspect of the Nano: its modular design. The Nano is constructed of components that can be built and shipped separately to be assembled in a variety of locations. In effect, the Nano is being sold in kits that are distributed, assembled, and serviced by local entrepreneurs.
