The Mother of All Design Challenges

First up, the remaining designers will try to reinvent the wheel-the steering wheel that is- using golf carts as their test vehicles. Then they must turn the Chevy Traverse into the perfect vehicle for a working mom, with veteran TV star, producer and mother Melissa Joan-Hart surveying each car as guest judge. Brooke Burns hosts and Jean Jennings and Harald Belker serve as judges.
