Car emissions is a high-stakes issue, as last year's Volkswagen scandal demonstrated. Pressure to meet tightening standards led the carmaker to cheat on emissions tests. But wrongdoing aside, how are automakers going to realistically meet future, tougher emissions requirements to reduce their impact on the climate? Researchers report today that a vehicle's cold start—at least in gasoline-powered cars—is the best target for future design changes.
