A Tata Nano was spotted testing on the Mumbai-Pune Expressway, and it could just be the Nano that you were waiting for. We believe Tata was doing efficiency runs on its new diesel Nano, as the two Nanos had data logging equipment onboard. It had been announced at the 2010 Auto Expo that Tata would collaborate with Bosch to make a common-rail diesel unit for the world's cheapest car.
Look for our comparision shot of the two engines.
What it appears is that a new heavier engine has been placed at the rear which sits lower than the regular petrol Nano. Moreover, the components of the bottom half also appear different from the regular Nano.
Bosch had announced earlier in the year that it was developing a common-rail system for the Tata Nano. UPDATED: While we haven't been able to confirm this bit of news, according to varied sources on the internet and some industry insiders, the car is expected to have a twin-cylinder diesel engine. Bosch has been doing the tuning and other aspects related to the car, and it could very well be a variation of the CRS 1.1 system that it has developed for single-cylinder diesels. We expect the gearbox unit to remain the same, except with different drive ratios than the one found on the petrol engine.
Earlier, Ratan Tata had mentioned to a news outlet that the Tata Nano diesel was to be made available "sooner than expected". Considering that production of the Nano will begin at Tata Motors new plant at Sanand in Gujarat and that production will be ramped up to meet existing demand, we expect the diesel Nano to hit showrooms before the end of 2010. Watch this space for further updates.
