When adjusted for an automobile traveling at 70 mph the Rotapower's harmful emissions levels were significantly lower than California's Super Ultra Low Emissions Vehicle (SULEV) standards. Unburned hydrocarbons (HC) are at 2 percent of the SULEV limit; carbon monoxide (CO) is just 1.3 percent; and nitrogen oxide (NOx) is at 35 percent. Sounds like we're going to be needing a new acronym... What's lower than "super ultra low?"
