Amongst the massive display from Tata at the Auto Expo 2010 is the Tata Aria production vehicle. The MPV is one of 37 cars at the company's booth, which also includes Land Rover and Jaguar.Using a 2.2-liter direct-injection common-rail diesel engine, the Aria will work with 138 horsepower, and up to 320 Nm of torque. Although sprint times, weight and top speed have not yet been revealed, expect the car to use that torque to launch forward, getting a bit sluggish as speeds increase. Optionally available is an all-wheel drive unit that delivers torque variably to each wheel, depending on driving conditions.Tata intentionally designed the seven-seater with enough height so "passengers can simply walk into the Tata Aria, rather than climbing" into it. If the driver has less than six passengers, the rear seats may be folded flat to increase cargo room. Interior features include an infotainment unit with GPS, dual climate zones, and surround sound. Six airbags will help keep everyone safe.Reports from the vehicle's introduction in New Delhi claim pricing will range from 700,000 to 1,000,000 Indian Rupees, or €10,600 to €15,150. First shown five years ago in Geneva as a concept, domestic market launch of the 2011 Tata Aria could begin by this summer.
