The premium engine manufacturer Bosch has finished the design of diesel engine meant for Tata Nano. Bosch is waiting for the formal launch of diesel Nano. The proposed engine will be of 750cc range and the full swing production will start by the Q3 or Q4 of 2011 fiscal. Bosch had invested Rs20000 crore for its global expansion which includes this diesel variant for Nano. Yet, there has been no official word from Tata about this despite its earlier commitment for alternative fuels for Nano.
The diesel variant of Nano would be ideal for those customers who switch over from two wheelers. But the technological question arises about the diesel engine being fitted at the rear of the car which may turn out to be a great challenge. Since the diesel engine is from CRS 1.1 common rail system, the cost would also be a snag(an estimated increase of Rs20000). However, Tata has started its trial production of Nano at the Sanand plant with the commercial production to start from this March.
