The All-Electric Tata Tigor EV Saloon
The Tata Tigor, internal combustion engine (ICE) passenger car was launched in 2017 and originated from the Tata Tiago hatchback. Though the Tata Tigor EV was initially launched in 2018, for use by the Government of India (GoI), the four-door pure electric Tata Tigor sedan was launched for the private market in October 2019.
Since its launch, the electric vehicle has performed well, with recent reports suggesting it to be the best successful passenger electric vehicle. The EV is also being acquired by fleet customers (commercial customers). The Tata Tigor EV is very similar in appearance to the petrol Tata Tigor, except for minimal changes. In September 2021 the pure electric car received a facelift.
The Tigor EV has a 26 kWh high energy density lithium-ion battery, with an emission-free range of 306 km on a single charge (ARAI certified range under standard conditions). Of course, the real world EV range will be lower depending on a number of conditions to include: driving conditions, road surface, driving style, driving mode, service used onboard etc. In general, the Tigor EV battery is smaller in size compared to electric cars manufactured by leading global automotive companies.
Saloon pure electric cars can range from 35 kWh to 100 kWh in terms of EV battery size. Interstingly, even the Tata Nexon SUV EV has a larger EV battery (30.2 kWh) compared to the Tigor EV. Given the general concern around range anxiety, EVs with a larger EV battery i.e. longer zero-emission range will be winners! Let’s hope that Tata Motors recognises this trend and introduces the Tigor EV with a larger EV battery!
The Tigor EV is priced for affordability and is without doubt one of the better priced pure electric cars not only in India, but also internationally. The EV is available in four variants (XE, XM, XZ+, XZ+ DT) with prices starting from Rs 11.99 L (ex-showroom). The EV price has increased as part of the facelift, but still remains affordable.
The EV is capable of fast charging (CCS2) and can be charged from 0% to 80% in 65 minutes. For home charging the EV can be charged via a 15 Amp plug point (0% to 80% in 8 hours and 45 minutes). In any case most EV are charged at home, overnight!
The EV has been built on the Ziptron EV platform and offers two driving modes: Drive & Sport. In the Sport mode, the EV is able to further enhance the instant torque. The EV achieves 0-60 km/h acceleration in 5.7 seconds. Top speed is capped at 80 kmh. The EV is equipped with regenerative braking (increases EV range), hill ascent assist and hill descent assist.
Tata Motors offers free home charge point installation, 24X7 emergency charging support (5 cities) and its wider national service network. The EV battery has an 8 years/ 160,000 km warranty.
The EV is equipped with a host of technology to include: 8.89 cm connectNext infotainment system by Harman, 17.78 cm connectNext floating dash-top touchscreen infotainment by Harman, FM, USB, I-pod connectivity, bluetooth connectivity, audio Streaming and Apple Car Play & Android Auto.
The EV also uses the Tata ZConnect mobile app, which is capable of 35 smart connected features to include: intrusion alert, stolen vehicle tracking, panic notification, remote immobilization etc, remote door lock/unlock, remote cooling, remote vehicle diagnostics, and remote lights ON/OFF. The EV is available in two colours: Daytona Grey & Signature Teal Blue.

History Of Electric Cars: Quick Facts
- An electric vehicle (EV), also referred to as a battery-electric vehicle (BEV) is not a new invention or even an invention of modern times. Indeed, EVs were first developed more than a 100 years ago in the 19th century. Put another way, Mahatma Gandhi was yet to be born, when inventors from various countries, to include European countries and the United States were already investing electric motors and batteries.
- The first practical electric cars were built in the second half of the nineteenth century, with the first US electric car introduced in 1890. Mohandas Karamchand Gandhi had just turned 21!
- Electric vehicles came into prominence in the early 1900’s, a time when horse-drawn carriages were the primary mode of transportation. Archived black and white photographs from that period show famous avenues like Madison Avenue in New York city filled with horse-drawn carriages. In stark contrast, a similar photograph taken a decade later of Madison Avenue showed not a single horse-drawn carriage. Instead the avenue was filled with motor vehicles, a new invention. It was the beginning of man’s love affair with cars that has lasted more than a century and still going strong.
- However, the uptake of electric vehicles in the early 20th century was short-lived, as gasoline powered vehicles propelled by internal combustion engines (ICE) become the preferred mode of transportation.
- Bottom-line, manufactures chose internal combustion engines over electric cars in the early 1900s for various reasons, to include, the costs and production volumes.
- It is not definitive as to where EVs were invented or to credit a single inventor. However, one known electric motor (small-scale) was created in 1828 by Anyos Jedlik, a Hungarian inventor, engineer, physicist and Benedictine priest. Hungarians and Slovaks still consider him to be the unsung hero of the electric motor.
- Shortly after, between 1832 and 1839, a Scottish inventor Robert Anderson created a large electric motor to drive a carriage, powered by non-rechargeable primary power cells. Through the 19th century a number of inventors were inspired to develop electric motors to include, Thomas Davenport, an American from Vermont credited with building the first DC electric motor in America (1834). Unlike many of his contemporaries and other trying to build electric motors, Davenport did not have a background in either engineering or physics. In fact, he was a blacksmith.
- Move forward a few decades and at the end of the 19th century, William Morrison created what is believed to be the first practical electric vehicle. Morrison, another American from Des Moines, Iowa, was a chemist who became interested in electricity. He build the first electric vehicle in 1887 in a carriage built by the Des Moines Buggy Co. His first attempt was not a great success. In 1890, he attempted again, with more success. 12 EVs were built using a carriage built by the Shaver Carriage Company.
- The batteries were designed and developed by William Morrison. The vehicle had 24 batteries with an output of 112 amperes at 58 volts that took 10 hours to recharge. Available horsepower just under 4 horsepower. The vehicle could accommodate 6 individuals and had a top speed of 14 mph (22.50 km/h).
- Morrison’s success led to others also developing large-scale practical electric cars. At the turn of the century cities like New York had 60 electric taxis. The first decade witnessed strong popularity for electric vehicles. However the popularity was short-lived as internal combustion engine (ICE) gasoline powered vehicles replaced the early electric vehicles. Henry Ford’s success with the then ubiquitous Ford Model T was the ‘beginning of the end’ for electric vehicles. The Model T was cheaper than the prevailing electric cars (US$ 650 Vs US$ 1,750) and could be manufactured at scale. As they say — the rest is history.
