Cummins unveils new engine platform

DUBLIN, Ohio — Cummins has taken the wraps off an all-new heavy-duty engine platform it feels will cement the 15-liter’s spot in the market by bringing additional efficiency and stronger performance.

Gone is the ‘IS’ from the name. The new 2017 engines are branded the X15 while an X12 will come online in 2018. The X15 is available in two versions: Performance and Efficiency. The Efficiency series is dialed in for maximum fuel economy while the Performance model is designed for more rigorous applications where additional torque and power are needed.

“The big bore engine is here to stay,” declared Lori Thompson, vice-president of marketing with Cummins when unveiling the engines to the trade press Friday.
