Tata Motors is in the process of upgrading the world’s cheapest car Nano in the coming few months. Acting on the feedback from the market, the car will get small but significant upgrades with in the next six months.

The Nano will get a higher rev limit at 6000 rpm compared to the conservative 5000 rpm earlier. The higher rev limit will improve performance especially in the first two gears allowing greater pull from the engine, important when going up an incline with full load, but the top speed will remain the same at 105 kph. Other changes include a newly modified outside rear view mirror which is less cumbersome owing to the movement of the mirror with in the casing negating the need for moving the whole assembly while adjusting. The newer design will also make it possible to introduce electric adjustment in the future if Tata Motors wants to. The doors will also have check straps to limit the door opening.

The most significant upgrade in the coming months will be the tailgate which can be opened improving the utility. The present sealed glass unit is inconvenient especially when there are passengers sitting on the rear seat . The limited capacity is also a blessing in disguise for the company as the changes can be in-corporated before the production is shifted to the main plant in Sanand, Gujrat.

Tata Motors is also in advanced stages of the development of the diesel engine which will be introduced by the end of 2011. The all new twin cylinder engine will be one of the smallest diesel engine with common rail technology and will develop a healthy 40 bhp.
