[1][2][3] The car's lack of visible seams is largely due to the use of its clamshell style roof which opens up to allow passengers to enter the interior.The car also uses a carbon-fiber chassis and a wooden frame under the bonnet, which was built with German bicycle manufacturer Keim, to function as a luggage rack.The car has two battery packs with independent cooling systems optimized by variable geometry honeycomb shaped air intakes in front.The car also has an OLED touchscreen covered with Gorilla Glass on both the center console and steering wheel.The steering wheel is rectangular and can extend in width when the vehicle is in autonomous mode to give the driver a panoramic view of the dashboard.
