The Volkswagen Kai-Nalu is a concept vehicle which was created by Josep Ferriol, a Spanish designer and graduate of the Universidad Politécnica de Valencia. The Kai-Nalu was created as part of his final year thesis.
The Volkswagen Kai-Nalu is a futuristic sports car concept that features a unique design which is composed of two distinctly different elements. Inspired by the waves of the Mediterranean sea as they smash into the shoreline and rocks near where Ferriol lives, the Kai-Nalu features a flowing glass upper section - which is designed to mimic the sea, and angular, jagged bodywork underneath - which represents the rocks of the coastline.
The mixture of the two differing shapes and textures is designed to present a dynamic and forceful appearance - much like the waves themselves. The Kai-Nalu's styling is quite controversial, and it isn't going to be to everyone's taste. However in a world where many sportscar and supercar concepts follow the same predictable formula, the Volkswagen Kai-Nalu is refreshingly bold and different.
Other highlights of the concept include highly stylized wheels which were inspired by the appearance of bicycle wheels. The VW logo in the center is balanced and mounted on a bearing so it always remains upright. The clear roof, windows, and upper bodywork also provides a glimpse of the vehicle's electric drivetrain, which features two seperate motors, one is mounted up front and the other at the rear to help balance out weight distribution.

However, that doesn’t mean BMW will keep the same design when the real one is launched. The convertible can seat 4 people and both the cars will come with 4 gasoline units and 6 cylinder turbo diesel which make things run very powerfully. The cars would come with an upgraded 3.0 litre petrol unit and also a 326HP 3.0 litre turbo charge. The car will in the end produce more than 500HP.
