We recently drove the Tata Bolt in its petrol form and while it turned out to be quite impressive we needed a drive of the diesel version too. Now while Tata Motors is pushing the Revotron 1.2T petrol (all cars at the media drive were petrols) we have also been getting questions regarding the diesel version so here is our first drive of the same.
First of all some numbers here and the Bolt diesel gets a 4 cylinder 1248cc 74 bhp engine with 190Nm of torque. This is the quite popular Quadrajet diesel engine in its less powerful avatar (Zest also gets a more powerful 89 bhp version). Also unlike the Zest the Bolt will not get an AMT version at launch instead it will have a 5-speed manual gearbox. While doing a comparison with the petrol is ideal our drive was too short for that but it did give us a first taste of a diesel manual version of Bolt as in the Zest diesel we are yet to drive the manual.
First impressions are quite good and after going past the lag the performance delivery is decent if not as good as the more powerful version in the Zest. However compared to the AMT Zest the manual gearbox equipped Bolt feels more lively thanks to well spread out gears and nice shift quality. At city speeds while you have to work the gearbox a bit the refinement levels are quite good. Fuel efficiency wise we expect the diesel to be more efficient over the petrol and you can expect 15-18 kmpl (official figure 22.95 kmpl)
As said earlier it was too short a drive to give a proper comparison with the petrol but on the evidence of this small taste we would say that the petrol just feels more lively and ultimately is more fun. With prices starting at Rs 5.50 lakh, it is about Rs 1 lakh more expensive than the petrol. So as it stands the diesel Bolt is for those who value efficiency more but we prefer the Bolt petrol as far as performance is concerned.
