Tata Motors' long-range version of its successful electric crossover, Nexon EV comes with a host of engineering innovations that aim to elevate the driving experience of this EV, christened the Nexon EV Max, and transform it into an exciting new package.
For starters, it now gets four levels of regenerative braking adjustment, empowering the driver to reach the most convenient stage of single-pedal driving in the highest Level-3 mode. There are toggle switches on the central console to increase or decrease the level of regeneration on the fly.
The company has also paid special attention to safety during regeneration and has offered auto-brake lamp activation function in the Max, despite there being no regulatory requirement for it in India yet. The function makes the brake lights glow to warn traffic that the vehicle is slowing down, and this kicks in as the regenerative braking crosses a particular threshold.
Explaining the introduction of this feature, Anand Kulkarni, VP, Product Line & Operations, Tata Passenger Electric Mobility said, "There are guidelines in certain markets that advise auto brake-lamp activation on regeneration. While we debated this internally, the feedback from the existing Nexon EV customers made us go ahead with this safety feature."
While electric vehicles typically suffer from brake-pedal pressure modulation challenge due to the combination of regenerative as well as normal braking, the Nexon EV Max features a unique intelligent vacuum-less brake-active control. Also known as the iVBAC device, the key to this is that it blends regenerative and normal braking to achieve optimal pedal feel. The hydraulic system eliminates the need of a vacuum pump used to drive the brake booster in a conventional car, and tries to maximise the braking efficiency during both regeneration as well as normal braking scenarios.
