Autocar to offer Cummins X12 engine

Starting in the fourth quarter this year Cummins X12 engines will be available in Autocar ACX model vehicles, the two companies announced Wednesday.

“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,” says Brett Merrit, vice president – 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.”

To meet customer needs, the Cummins X12 boasts a remarkably low engine weight of 2,050 lb. that doesn’t compromise on durability or performance, the company says. 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 lb., versus Cummins’ previous 12-liter engine. That’s 733 lb., more payload available, Autocar says.

“Autocar is focused on bringing innovations to the market with real, tangible benefits to our customers,” says 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.”

Cummins says 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 lb., considerably lower than that of any other heavy-duty system, the company says.

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