ata Motors today presented at the 81st Geneva Motor Show the Tata Pixel, a new city car concept for Europe. Based on the Tata Nano, the Tata Pixel -- at just over three metres in length -- is the most package efficient four-seater in the world, comfortably accommodating four adults, unlike a typical city car which is either a two-seater or can accommodate two adults and two children only.The Tata Pixel's ability to manoeuvre and park in the tightest of spaces is made possible by its Zero Turn toroidal traction-drive Infinitely Variable Transmission (IVT), which assists rotation of the outer rear wheel forwards and the inner rear wheel backwards, while the front wheels turn at acute angles. The result is a turning circle radius of just 2.6 metres. The 'scissor' doors rotate upwards from the front to allow passengers to effortlessly enter or exit the Tata Pixel, even in the tightest of spaces.A 1.2 litre three-cylinder turbocharged diesel engine, positioned at the rear of the Tata Pixel, gives lively performance. The engine is a low-friction design, featuring variable coolant and oil pump and rapid warm-up technologies. With optimised aerodynamic drag, low rolling-resistance tyres, stop-start technology, and intelligent battery charging, the Tata Pixel returns European combined cycle (NEDC) fuel economy of 3.4 l/100km and CO2 emissions of just 89g/km.A forward sweeping roofline, with minimal front and rear overhangs, accentuates the youthful styling. The Tata Pixel is also designed to provide a high level of connectivity. Key functions are controlled by the driver's smart phone, running 'My Tata Connect' -- the first integrated human-machine interface (HMI) concept from Tata Motors.
