Autocar introducing Cummins X12 in its haulers

April 18, 2018
The light-weight engine will be available in ACX models in late 2018.

Autocar, an American manufacturer of severe-duty, cabover vocational trucks, will introduce the Cummins X12 in its ACX model starting in the fourth quarter of 2018.

The X12 meets the needs of its customers by boasting a remarkably low 2,050-pound engine weight that doesn’t compromise on durability or performance, the company said.

“With its best-in-class power-to-weight ratio, Cummins believes that the X12 engine will be well-suited to address the needs of the refuse market as well as other weight sensitive vocational applications,” said Brett Merrit, vice president for Cummins’ on-highway engine business.

“Autocar is a key player in the North America refuse market, and this introduction will further our current collaboration across diesel and natural gas platforms.”

Delivering up to 500 horsepower (373 kW), the X12 has the highest power-to-weight ratio of any comparable engine in the market. Haulers specifically with the Autocar ACX powered by the X12 engine will see a significant weight savings of 733 pounds versus Cummins’ previous 12-liter engine. That’s 733 pounds more payload available.

“Autocar is focused on bringing innovations to the market with real, tangible benefits to our customers,” said Jim Johnston, president of Autocar. “This new engine puts more cash in our customers’ pockets, plain and simple.

“We’re gratified that Cummins trusts us to bring the X12 engine to the refuse market first.”

The X12 uses the latest Single Module aftertreatment system, which takes up to 60-percent less space and weighs up to 40-percent less than prior aftertreatment configurations. Combined engine and aftertreatment weight for the X12 is around 2,240 pounds – considerably lower than that of any other heavy-duty system.

“Built around improved uptime and reliability, the X12 will be in prime position to support Autocar’s vision of ‘Always Up’” Merritt said.
