Reliable power

Manufactured in some of the world's most modern and highly-automated production facilities, the Cat® C1.1 is proven to deliver durable power and offers a wide range of customization options that refuse to compromise quality and durablity.

Compact size

With a 18.4 kW (24 hp) power rating, the C1.1 and the C1.1 turbo allows OEMs to consider different installation, operating and commercial requirements. These models are particularly adapted to machines where power from a small
package is crucial. And for jobs that require that extra bit of power, there's a turbocharged option that delivers in almost any condition, at any altitude.

Quiet work

The stiff block and indirect injection system in the C1.1 were built for quiet so worksites are safer, operators are less
fatigued and noise levels in regulated areas aren't exceeded.
