The resulting car is called the MAX: Mother's Automotive eXperiment. Although the initial goal was to reach the 100 mpg mark set for the Auto X Prize, the resulting car turned out to be a little far from this objective and was totaled in an accident. Thankfully, nobody was seriously injured.
McCormack has rebuilt the car and hopes to accomplish the X Prize target with a custom-built streamlined body on a Locost chassis, a 32-horsepower three-cylinder diesel engine from Kubota, old Toyota Corolla parts and plenty of custom bits and pieces. The car is driven either with diesel, biodiesel or SVO (Straight Vegetable Oil). You can read the complete story at his site. We wish McCormack the best!
