Tata Ultra E.7 Launched: An Overview of Tata Motors Electric Medium-Duty Truck

At an event held today at Bharat Mandapam, Tata Motors unveiled 17 commercial vehicles across multiple segments, marking one of its larger coordinated product introductions. All vehicles launched at the event are certified to ECE R29.03 European cabin safety norms, underlining a broader focus on occupant protection alongside product expansion. Among the introductions was the Tata Ultra E.7, an electric medium-duty truck positioned in the 7490 ton gross vehicle weight category.

The Ultra E.7 is intended for use in intra-city logistics. The primary applications include FMCG distribution, E-commerce and Scheduled Urban Transport. These applications always have predetermined routes, known distances and a daily Return-To-Base operation, which is well-suited to electric vehicles. 

Electric Drivetrain and Power Delivery

The Tata Ultra E.7 uses a Permanent Magnet Synchronous Motor (PMSM). The motor develops a peak power output of 240 kW. Peak torque reaches 950 Nm, with continuous torque rated at 450 Nm. This output profile can support frequent acceleration and deceleration-the requirement for dense urban traffic conditions.

Power flows through an integrated E-axle, incorporating the motor, transmission and axle into one package. This system reduces drivetrain components to a minimum. Simplifying the mechanical architecture, the layout allows for more direct torque delivery to the wheels.

Battery Configuration and Charging

Energy is stored in a 96 kWh LFP battery pack. The use of LFP chemistry ensures very good thermal stability and an extended cycle life for vehicles running daily under repeated charge–discharge cycles.

The Ultra E.7 has CCS2-compatible charging. Charging time, according to the brochure, can range from 15 to 20 hours, depending on charger capacity and the availability of power. Tata Motors claims a driving range of up to 180 kilometres at a trot, placing it firmly in the single-shift urban duty category rather than a long-distance haulage mode.

Suspension, Braking and Road Capability

Suspension duties are being taken care of by parabolic leaf springs with shock absorbers in both the front and rear suspensions. In this manner, both load-carrying ability and suspension are equally well provided for. Braking duties are being handled by hydraulic disc brakes. The Ultra E.7 has a restart gradeability of 26 percent. This function assists in engaging flyovers, load ramps and inclined urban routes while under load.

Payload and Dimensions

The vehicle is fitted with a 14-foot load deck that enables it to utilize container and box body configurations that are ideally accommodated by city logistics. The payload is estimated at 3,100 kilograms for a vehicle with a container. A 3,550mm wheelbase is also featured.

Operating Positioning

Tata Ultra E.7 is not marketed as a solution that can replace diesel trucks in every scenario. It is more suitable in contexts where trucks have fixed routes and their respective distances are predictable and calculable, enabling efficient charging and down time management.
