The two international models are twins, both based on an improved version of the X1 platform used for the Tata Indica Vista. The only differences are that the Zest gets LED DRLs and 16-inch wheels instead of the Bolt's 15-inchers, and the Zest gets the option of an automated manual transmission. Otherwise, Tata appears to be intent on giving both offerings segment-first or segment-defining features.
Both cars get the option of a turbocharged, 1.2-litre Revotron gas engine with 84 horsepower and 103 pound-feet of torque, as well as a 1.3-litre Multijet turbodiesel with 75 hp and 140 lb-ft. The Bolt makes do with a five-speed transmission affixed to either engine, while the Zest can be fitted with the F-Tronic automated manual.
Other features available on either car include Harman infotainment systems with five-inch touchscreens, Bluetooth with voice recognition and text-to-speech, speed-sensitive electric power steering, ABS with cornering stability and driving dynamics tuned by former Indian Formula One driver Narain Karthikeyan. Their designs are said to have come from the company's three design studios in the UK, Italy and India. You'll find their launch videos below.
