The launch of the lightweight, fuel-efficient PACCAR MX-11 Engine for North American mar- kets is the culmination of a research and development process that has been more than seven years in the making, according to PACCAR Assistant Vice President Landon Sproull. In fact, Sproull notes that wheels began turning on the new engine long before the MX-11's popular stablemate, the PACCAR MX-13, was introduced to North American markets in 2010. As with the successful MX-13 launch, insight into the North American launch start- ed with a study of European markets. With PACCAR subsidiary DAF, a leading European truck and engine manufacturer that has been building engines for more than 50 years, PACCAR executives were uniquely positioned to monitor trends in the European markets. And as Euro 6 emissions standards in European Union countries grew tighter, so grew a heightened interest in fuel efficiency and weight savings. Thus the trend toward smaller engines in EU countries, according to Sproull. Despite inherent differences in truck markets on the two continents, PACCAR officials were keen- ly aware that what the market demands in Europe is often not long from being a market demand in North America. "Trends in Europe often provide some foreshadowing to what will happen in North American markets," says Sproull. "They're a little further ahead in some regards. The trends there suggested that customers buying trucks are downsizing their engine choices." As a result, PACCAR began producing MX-11 compo- nents for Europe at the Columbus, Miss., engine plant in 2013.
