Volvo Trucks and Mack Trucks said 13-liter engines have become the number one choice of U.S. Class 8 truck customers, and that they sell more 13-liters than any other company.

Mack also said it was the top seller of 11-liter engines in the United States.

The two companies, both based in Greensboro, N.C., are units of Swedish-based global manufacturer Volvo AB.

“For the first time, 13-liter engines have become the number one choice of U.S. Class 8 truck customers, and no one sells more 13-liter engines — or 11-liter engines — in the U.S. than the Volvo Group,” Volvo’s statement said.



“The Mack MP7 engine is also the top-selling 11-liter engine in the U.S.,” Mack said.

Both companies said that data substantiating their statement came from R.L. Polk & Co, which collects registration data on commercial vehicles and components.

“We’re seeing a shift in the market to less than 15-liter engines as customers increasingly focus on operational efficiency,” said Kevin Flaherty, Mack’s senior vice president for the U.S. and Canada.
