We already showed you the first images of the new battery electric Focus that Ford has built for the guests of the new Jay Leno show to use in his Green Car Challenge. Now Ford has also posted a video with some of the engineers showing off their handiwork. Once the team's Lisa Drake, chief engineer at Ford's sustainable mobility technology lab, got the Euro-spec focus electrified, it was time for the Ford Racing crew to charge it up. Andy Slankard, engineering supervisor at Ford Racing, describes the work done to prepare the car for its TV life. While the two show cars started life as Focus ST models, the new powertrain and the added mass of the 23 kWh battery pack meant the suspension needed some help. With the pack sitting in the cargo hold at the back, the weight balance was undoubtedly shifted rearward. Still, the car looks pretty good going through the autocross. Check out the video after the jump. Thanks to Clifford for the tip!
