The proposed engine for the concept is a three-rotor turbocharged rotary engine developing more than 700hp. The target of the project was to create a chassis that’s more rigid than the stock version but keeps the car’s total mass under 1,200kg. Some of the innovations include a new carbon-fiber roof, gullwing doors (these actually stiffen the chassis since they act as a roll cage), a tilted windscreen and new heat outlets positioned in the doors.
To keep costs down, Zammit’s design leaves a number of features from the standard RX-7 unchanged. Parts that were left untouched include the windshield shape, wheelbase, vehicle track and running gear.
