Small is beautiful, is definitely the new mantra post the arrival of the Tata Nano. Multiple companies are working on ultra small cars, which would rival the Nano and Maruti Alto. However, General Motors has a easier task. They don’t have to develop a car from ground up. All they need to do is slap on a smaller engine to the Chevrolet Spark and voila! The American automaker will launch an 800cc version of the Spark by the end of the year. This would help the company reduce prices of the car by close to Rs. 30,000/-. The 3-cylinder motor in the Spark 800cc will also be more fuel efficient, something of prime importance to small car buyers.
