Tata Motors unveiled the Tata Megapixel concept, a four-seater, global range extended electric vehicle (REEV) concept. Combining a lithium-ion phosphate battery and an on-board gasoline engine generator, the Tata Megapixel offers a range of up to 900 km (559 miles) and CO2 emissions of 22 g/km.
The ‘Zero Turn’ drive system of the Tata Pixel (shown at the 2011 Geneva Motor Show) has been taken to a higher level of maneuverability in the Tata Megapixel. The car’s electric drive has four independent electric motors, one at each wheel. When parking, the electric hub motors drive the wheels in opposite directions, while the front wheels are turned at an acute angle, enabling an 2.8 meter turning radius.
The Tata Pixel’s Zero Turn system is enabled by its toroidal traction drive infinitely variable transmission (IVT), which assists rotation of the outer rear wheel forward and the inner rear wheel backward, while the front wheels turn at acute angles. The result in the Pixel is a turning circle radius of 2.6 meters.
The MegaPixel uses an at-home wireless induction charging system.
