It’s also reduced in length by 20%, height by 5% and weight by 40%*—which all adds up to significantly less installation time and cost for you.

Cut Costs, Not Corners.

The Cat C7.1’s savings result in peak productivity.

Downsizing comes with plenty of benefits, including an 18% decrease in fuel consumption. The C7.1 delivers those savings, along with 4% less DEF consumption and EGR integration. Its passive regeneration technology lets you perform your toughest tasks in the harshest environments, keeping uptime at its peak. When you downsize from a 9-litre engine to the C7.1, you’ll experience reduced length by 20%, height by 5% and weight by 40%*—making it your right-sized, rock-solid source of power.
