Okay, so it’s not the fastest or most impressive test drive we've ever had. (The kart suffered a[nother] MOSFET failure after a few runs.) But it highlights one of the new features: a custom-built rear axle differential. With this addition, and savings of about 100lbs by switching to lithium-ion batteries, it easily navigates the slalom course. Back in 2008, clearing the u-turn was nearly impossible even at low speeds.  Don't ask why Elmo is used as a slalom cone. For more info about the Cap Kart, see
