The manufacturer describes it as a car built for European cities based on the Tata Nano.
Tata claims the Pixel will be "the most package efficient four-seater in the world".
The company's use of high-tech in the new vehicle includes connected services and Tata's own human-machine interface (HMI) concept.
The Pixel also has an infinitely variable transmission from Torotrak and a 1.2 litre turbo diesel offering 3.4 l/100km.
Tata says its biggest sales point will be its ultra-manoeuvrability thanks to moveable wheels and a turning circle of just 2.6 m.
The Pixel's manoeuvring ability in very tight surroundings is due to the Torotrak Zero Turn toroidal traction-drive Infinitely Variable Transmission (IVT).
By moving the outer rear wheel forward and the inner rear wheel backward, while the front wheels turn at more acute angles the car essentially pivots around its rear axle.
As mentioned, the resulting turning circle radius is just 2.6 m.
Suitable for a future city car, "scissor" doors enable the driver and passenger to get out of the vehicle without requiring any door sweep.
Key functions are controlled by the dri-ver's smart phone, running "My Tata Connect". This system essentially uses the driver's own smartphone or tablet as a central information display and touch-screen control panel for the car's entertainment and internet system.
Docking the tablet allows a range of displays of the vehicles performance and adjustments, for example the air conditioning settings.
The turbo-charged three-cylinder diesel engine is high tech too - with a variable coolant and oil pump and rapid warm-up technologies.
The car has been optimised for aerodynamic drag in a wind tunnel, uses low rolling-resistance tyres and stop-start technology to return a 3.4 l/100km European combined cycle (NEDC) fuel economy figure.
