Each platform symbolizes a milestone in Tata’s road to electric mobility, and we’ll go through each one in detail.
Tata has been India’s leading EV brand for a long time, thanks to a well-positioned product that offers a practical variety at reasonable pricing. In 2022, the company unveiled two new designs that foreshadow the future of Tata electric vehicles, both based on new architectures known as Gen2 and Gen3. Let’s look at how they differ from one another and from the Gen 1 EV platform.
Existing Tata EVs, such as the Nexon EV and Tigor EV, are built on the Gen1 platform. These are electric versions of Tata’s current combustion-engine cars.
The Gen2 design is a step up over its predecessor and is scalable to accommodate models of all sizes. Like Gen1, it will be able to produce both EVs and ICE vehicles. In comparison to Gen1, this platform focuses more on EV compatibility than ICE compatibility.
Meanwhile, Gen3 is solely for electric vehicles. As a result, it’s designed like a skateboard, with more space between the axles to accommodate the battery pack beneath the flat floor. EVs based on the Gen3 platform will also be targeted at markets outside of India. Tata is expected to introduce premium electric vehicles in the future.
So far, the two models available on the Gen1 platform are both under 4m. Both have a confirmed range of just over 300 kilometers and can be charged with 50kW DC fast chargers. (The Nexon EV Max, the most recent model based on the Gen1 architecture, has a larger battery pack and a range closer to 400 kilometers.)
For enhanced performance and range, the EV-focused Gen2 architecture can handle updated drivetrain systems and larger battery packs. Tata claims that EVs built on this platform will have a range of 400 to 500 kilometers. They’d also be able to charge more quickly from both AC and DC sources.
Tata is aiming for a minimum certifiable range of 500 kilometers with its Gen3 EVs. It will also provide them with the necessary power infrastructure to enable them to add up to 500 kilometers of range in 30 minutes. There is currently no EV with a claimed range of 500 kilometers priced less than Rs 30 lakh.
While Tata EVs based on the Gen1 platform have basic use of the electric powertrain, future architectures can do more. The Gen2 platform will support EVs that can share their charge with other EVs and use a 3-pin connection to power household appliances. Vehicle-to-load or vehicle-to-vehicle charging is the term for this capability.
Tata claims that its Gen2 EV cars will have improved connectivity for telematics and over-the-air upgrades, as well as the ability to operate more complex computing systems that could enable ADAS features.
Beyond the ADAS features now available in mass-market automobiles costing below Rs 20 lakh, the Gen3 EV is believed to be capable of autonomous driving technology. This architecture also offers safer electric vehicles due to its structural design, as well as greater battery protection in all types of climates and terrains.
The potential to offer significantly more internal space from the given proportions is the most significant advantage of Gen3 architecture. It can offer cabin room comparable to the Harrier while being similar in length to the Hyundai Creta, as seen in the Avinya concept.
The production-spec version of the Concept Currv electric SUV coupe will be the first model to use the Gen2 platform. Tata claims that the concept is nearly ready for the road. The Currv’s ultimate market-ready version is expected to arrive in 2024.
Surprisingly, the Gen3 EV is expected to debut in 2025, with a production-ready variant. The initial product will be a ready-to-market version of the Avinya concept.
In the meanwhile, new Gen1 EVs and/or different models with a longer range are possible. The electric versions of the Altroz luxury hatchback and the Punch compact SUV are the two models that have previously been confirmed. Tata appears to be on track to meet its goal of having 10 electric vehicles in its lineup by 2025.
