Cummins updates 15-liter lineup for 2020

Cummins for the coming model year will expand its X15 portfolio with a new X15 Efficiency Series engine and new X15 Productivity Series ratings.

The 2020 X15 Efficiency Series engine, Cummins said, delivers up to 5% better fuel economy than the prior X15 Efficiency Series, and a longer oil drain interval of 75,000 miles. The new X15 Productivity Series offering, through its expanded range of ratings, will be able to serve more markets.

“The new 2020 X15 Efficiency Series engine provides improved fuel economy and further reduces greenhouse gas emissions,” said Brett Merritt, vice president of On-Highway Engine Business at Cummins. “That’s why we’re bringing our new X15 Efficiency Series engine and X15 Productivity Series offering to the market a year ahead of regulation requirements.”
