| Emissions |
The Cat C7.1 engine meets U.S. EPA Tier 4 Final/EU Stage V and Korea Tier 4 Final emission standards. |
| Note (1) |
*Range 4 power and torque is equal to Performance Mode with Caterpillar Power by Range technology. |
| Note (2) |
Net power ratings are tested at the reference conditions for the specified standard and denote power available at the flywheel when the engine is equipped with alternator, air cleaner, emission components and fan at specified speed. |
| Note (3) |
No derating required up to 3000 m (10,000 ft) altitude. Auto derate protects hydraulic and transmission systems. |
