Tata Tiago EV XT Long-Range Vs Tiago XT CNG - Price Comparison

While the upfront ex-showroom cost difference between the Tiago XT CNG and Tiago EV XT long-range stands at Rs. 2.97 lakh. It’s worth noting that the Tiago EV offers the convenience of an automatic transmission. The Tiago CNG is only available with a manual transmission. If we give an advantage of Rs. 70,000 to the Tiago EV for the convenience of an automatic transmission, then the price gap drops down to Rs. 2.27 lakh. You can adjust the price of the automatic transmission in your calculations based on your perceived value and the importance you give to an automatic transmission in city traffic driving.

Now, this Rs. 2.27 lakh is the price the Tiago electric has to justify with the features, performance and lower running costs.

Tata Tiago CNG Vs EV - XT Variant - Feature Comparison

Among the most notable features the Tiago EV XT Long Range offers over the Tiago CNG XT variant are:

• Auto AC
• Power folding ORVMs with auto fold
• Tyre pressure monitoring (TPMS)
• Telematics

However, even the Tiago CNG has the following features, which aren’t available in the Tiago EV:

• Spare wheel
• Height-adjustable driver seat

In this case, the Tiago EV seems to offer about Rs. 17,000 worth of value with additional features over the Tiago CNG XT variant.

Now, the Tiago EV has to justify Rs. 2.10 lakh with its performance and lower running costs to make it a sensible upgrade over the Tiago CNG.

Tata Tiago CNG Vs Tiago EV - Performance Comparison

In terms of performance, the Tiago EV has 2PS and 19Nm higher output than the Tiago CNG. It also enjoys the convenience of an automatic transmission as you don’t have to change gears in the Tiago EV. Like most electric cars these days, this electric hatchback uses a single-speed reduction gear and doesn’t use a multi-ratio transmission. However, we’ve already factored in this convenience in the price section.

In the performance section alone, the Tiago EV justifies about Rs. 15,000 worth of cost with its higher power and torque output.

Now, the Tiago EV has to justify the Rs. 1.95 lakh price difference to warrant an upgrade over the Tiago CNG.

Tata Tiago EV Vs CNG - XT Variant - Running Cost Or Fuel Cost Comparison

In terms of fuel costs, the Tiago CNG has a mileage of 26.49kmpkg. This results in a fuel cost of Rs. 3.0 per kilometre.

The Tiago EV Long-Range has a range of 315km from its 24kWh battery pack. This results in an efficiency figure of 13.13kmpu. This means, that based on the official claims, you can drive the car for about 13.13km for every unit or kWh of electricity. At this efficiency, the Tiago EV will cost Rs. 0.76 for every kilometre you drive with the assumption that the electricity cost in your area is Rs. 10 per unit. You can accordingly use your estimated electricity cost to adjust the calculation for your usage.

With these figures in mind, we can see that the Tiago EV long-range saves Rs. 2.24 per kilometre compared to the Tiago CNG.

Since we have to recover Rs. 1.95 lakh, we can expect to break even this amount in running cost savings in about 87,100km.

With such a high km-to-breakeven figure for the Tiago EV Long Range over the Tiago XT CNG, we can’t recommend the Tiago EV XT variant for fuel cost savings. If you are an early adopter of new technology, then you can go ahead with the purchase. However, for most car buyers, the Tiago EV XT Long Range is not a suitable purchase because of its high km-to-breakeven figure.

Please note that we arrived at this figure after considering the performance, features and automatic transmission advantage. If you don’t value these much, then the km-to-breakeven figure will be even higher.
