The new Nissan IDx Nismo and Nissan IDx Freeflow concepts are awesome from the moment we first laid eyes on it for one very brilliant reason: it has Datsun 510 DNA written all over it. Also known as the Nissan Bluebird, the 510, sold from 1968 to 1974, remains one of the most iconic Nissans of all time and was even regarded as the poor man's Japanese BMW 2002. 

Today, the new Nissan IDx concepts ignited the 2013 Tokyo Motor Show with two sensational design studies. First, the Nissan IDx Freeflow represents the standard model with a slant towards the casual lifestyle for the young, simple, and frugal consumer. The Nissan IDx Freeflow puts an emphasis on minimalist styling and simplicity, encouraging young enthusiasts to apply the Freeflow as a blank canvas to build into the cars they want.

Next, the Nissan IDx Nismo is the performance model that combines modern digital styling with Nissan's racing heritage. More specifically, Nissan's classic BRE double racing stripe is flawlessly recreated in red along the doors.

Details and specs on the Nissan IDx Nismo and IDx Freeflow are limited but we expect Nissan will indulge us with more details in the days ahead. In the mean time, be sure to check out the promo video below:
