Let’s see how much extra will you have to shell out for the Tiago EV as opposed to buying the CNG version, and how different their daily running costs are

Tata Tiago EV and Tiago CNG

Tata’s most affordable EV, the all-electric Tiago, has been launched and is sold in four trims: XE, XT, XZ+, and XZ+ Tech Lux. The Tiago is now the only hatchback in India which is available in three powertrain versions: all-electric, internal combustion engine (ICE), and CNG.

While we have already covered the EV vs petrol-auto comparison of on-road and running costs, in this story let’s put the Tiago EV head-to-head with its CNG counterpart. Do note that the CNG variants get only the five-speed manual gearbox, while the EV is only available with an automatic transmission.

First, let’s see their on-road prices:

Variants (On-road prices in Pune)	Tiago EV	Tiago CNG	Difference
XE	Rs 8.85 lakh	Rs 7.21 lakh	Rs 1.64 lakh
XM	–	Rs 7.55 lakh	–
XT 19.2kWh	Rs 9.47 lakh	Rs 7.93 lakh	Rs 1.54 lakh
XT 24kWh	Rs 10.40 lakh	–	–
XZ+ 3.3kW charger	Rs 11.33 lakh	Rs 8.80 lakh	Rs 2.53 lakh
XZ+ 7.2kW fast charger	Rs 11.85 lakh	–	–
XZ+ Tech Lux 3.3kW charger	Rs 11.85 lakh	–	–
XZ+ Tech Lux 7.2kW fast charger	Rs 12.38 lakh	–	–

Takeaways

Tata Tiago EV

Tata offers a CNG kit right from the base-spec XE trim of the standard Tiago. When prices of the base-spec XE trims of the all-electric Tiago and the Tiago CNG are compared, the former’s starting price is more than that of the latter by over Rs 1.5 lakh.
The XT trim of the EV is pricier by more than Rs 1.5 lakh compared to that of the Tiago CNG, while the premium goes over Rs 2.5 lakh when their respective XZ+ trims are considered.

The Tiago EV gets two battery pack options: 19.2kWh (250km) and 24kWh (315km). It also supports DC fast charging, which juices up its battery pack from 10 to 80 per cent in 57 minutes. Around three and a half hours will be required for the same when a 7.2kW AC charger is used, while the smaller battery takes less time, around 2.6 hours.

Daily Running Costs Compared Based On Claimed Figures

	Tiago EV		Tiago CNG
Battery pack/ Fuel tank capacity	19.2kWh	24kWh	35 litres (petrol), 60 litres CNG tank (water-equivalent)*
Efficiency (claimed)	13.02km/kWh	13.13km/kWh	26.49km/kg (CNG)
Public Charging Cost per unit / CNG Cost (In Pune)	Rs 18 per unit (kWh)		Rs 91/kg
Range (claimed)	250km	315km	910km (CNG+petrol), 265km (CNG only)
Full charge/ Tank up	Around Rs 350	Around Rs 450	Around Rs 900 (CNG only)
Per km running cost	Rs 1.4 per km	Rs 1.43 per km	Rs 3.4 per km (CNG only)
Monthly running cost (Average 50km daily)	Rs 2,100	Rs 2,145	Rs 5,100 (CNG only)
Running cost for 20,000kms	Rs 28,000	Rs 28,600	Rs 68,000 (CNG only)

*Considering it’s equivalent to 10kg

Note: We have only considered the public-charging costs for this comparison. The home-charging rates are much lower than the former, hence the running costs in those scenarios will also be much lesser for the Tiago EV.

Tata Tiago CNG

Now, we have calculated the daily running costs of both models based on Pune prices (fast charging CCS-2 Tata Power station) and claimed efficiencies. So, the Tiago EV’s per kilometre running cost is around Rs 1.4 , as opposed to Rs 3.4 of its CNG counterpart.

With an average daily running of 50km, you’re spending around Rs 2,100 monthly with the Tiago EV, while the running cost of the Tiago CNG is over two times more.
