Assuming the report from Autocar, the Pixel will replace the previously-proposed Nano once the doors have been converted to traditionally-opening units and the gauges have been engineered.
The Pixel will be powered by the Nano's 60-horsepower, 1.2-liter diesel, which will be mounted under the back seats, turning a five-speed gearbox. No word yet on when Tata plans to have the car on sale, but it seems to be pushing through quickly.
