When local off-road racer "Pistol" Pete Sohren closed his Speedway indoor kart-racing business, Valley go-kart enthusiasts weren't left with many options — that is, until national chain K1 Speed opened a Phoenix location in the old Speedway building. Visitors can now enjoy all the medium-octane (45 miles per hour, max) excitement of whizzing around an indoor track on a go-kart — minus noxious exhaust fumes. All K1's karts are electric, which means you can race with a group of friends, and spectators won't have to shout at each other or gag on the smell of gas. As a company, K1 has credibility — professional racer Boris Said is a co-owner — and the tracks are designed to mimic those in NASCAR. Plus, the lobby is pretty pimp, all decked out in custom paintings of cars, chrome siding, and shiny arcade racing games, with plenty of black leather couches and chairs for resting after the big race.
