Touch Down is a futuristic car concept which provides you a glimpse of what a green four-wheel drive may look like 20 years hence. Designed by Guo Ke, the concept recently won the Silver Award of Best Harmonious Beauty at the First “Science & Future” International Concept Car Design Contest. The completely zero emissions car runs on batteries charged by solar or wind power plants. Touch Down’s rear is equipped with a battery tank which contains a total of six high-capacity batteries that can be removed and recharged independently. Green credentials apart, this futuristic car which claims to take you on a ride at the speed of an aircraft has an eye-catching sleek design with a low body and electric motors in its tires allowing in-wheel drive.
