This series was released in 2008. For this series, Mattel went outside the company and got designers from automakers Ford, Mitsubishi, Chrysler (Dodge), Lotus, Honda, and GM (Chevrolet) to design a Hot Wheels casting. Hot Wheels designer Jun Imai designed the last casting in the series, HW40.

From the back of the cards:

Designer's Challenge™
The Designer's Challenge™ program was created as a way for Hot Wheels® to actively include its automotive partners in its 40th anniversary celebration by creating exclusive designs for a brand new line. It marks the first time Mattel has ever turned outside the company for original Hot Wheels® designs. The challenge for each automotive manufacturer was to create a Hot Wheels® car that truly captured the brand's core values of speed, power, performance and attitude, while also retaining the distinct attributes of each company's brand essence. All submissions were judged by a panel of Hot Wheels® designers and collectors, as well as automotive journalists from Car & Driver magazine, the Los Angeles Times and Men's Journal. The panel selected one design from each manufacturer and one internal design to be transformed into authentic Hot Wheels® cars. To learn more, go to!
