Caterpillar Industrial Power Systems showcases a range of optimized, fuel flexible engines, integrated advanced power technologies and services solutions at bauma 2025.
Powering today – the new C13D, optimized and fuel flexible engine
The 13-liter diesel engine platform is designed to achieve best-in-class power density, torque and fuel efficiency for optimizing the performance of heavy duty off-highway applications.
The inline, six-cylinder Cat C13D engine platform will offer eight power ratings from 340-515 kW (456-690 hp) with up to 3,200 Nm of peak torque. Engine-mounted aftertreatment and cooling packs will also be available from the factory to reduce installation and validation costs. The C13D will meet the emissions standards of highly regulated markets, such as EU Stage V, U.S. EPA Tier 4 Final, China Nonroad Stage IV, Korea Stage V, and Japan 2014, with models available for less regulated markets.
By supplying more power and torque available from Caterpillar’s current 13-, 15- and single-turbo 18-liter engine platforms, the C13D platform provides an opportunity for OEMs to downsize the engine and simplify design, assembly, and supply chain requirements across multiple applications. This consolidation can also reduce maintenance, parts, and technical training complexity for end users.
The Cat C13D, which goes into production in 2026, is designed for use in a wide range of off-highway equipment, including rock crushers, screeners, and grinders; trenchers; agriculture tractors, harvesters and self-propelled sprayers; woodchippers; material-handling equipment; and large industrial pumps.
The Cat C13D engine platform also enables the use of renewable liquid fuels such as 100% HVO, up to B20 for models with aftertreatment and B100 for models without aftertreatment.
Extending lifecycles with aftermarket services and Cat Reman products
To enable customers to extend the lifecycle of their engine across their fleets, Caterpillar is exhibiting a range of flexible parts and services solutions to support each stage of the engine lifecycle, including Extended Service Contracts, Customer Value Agreements, parts, repair options and its global dealer network. And an interactive simulator will promote the importance of condition monitoring for proactive diagnostics and right first-time fix to reduce downtime.
The exhibit features a deconstructed Cat C7 Reman engine including Cat remanufactured parts and end-of-life parts, also known as core. The display shows the contrast between core and Cat Reman parts to better highlight the impressive remanufacturing processes that take place in Caterpillar facilities. Cat Reman products help the OEM to extend their machine’s lifecycle, reduce waste and keep the engine running strong. Fully assembled and ready to run, Cat Reman complete engines are dynamometer tested and tuned for like new performance and fuel efficiency. With an extensive offering from simple components to overhaul kits to complete engines, Cat Reman enables customers to reduce downtime, get back into operation fast and benefit from like new performance on the toughest jobs.
Driving tomorrow – new series hybrid power expansion powertrain
Caterpillar offers a wide range of options, including a variety of non-traditional drivetrain solutions, offering options in both fuel flexibility and a reduction in greenhouse gas (GHG) emissions.
At bauma, Caterpillar combined its diesel electric experience with its battery experience to showcase a hybrid solution for customers looking to reduce their emissions and increase system efficiency. The series hybrid power expansion powertrain is an advanced electrified system designed to optimize power efficiency, performance, and fuel consumption across demanding applications.
At its core, a rugged Cat engine drives a generator, converting mechanical energy into electrical power. The inverter manages power distribution, directing energy from the generator and battery to the electric motors, which drive the machine.
The hybrid capability allows for zero-exhaust emissions when running on battery power, and with the proper equipment, the series hybrid power expansion powertrain can become a mobile power source with power export capability for stand-alone power use.
The series hybrid power expansion powertrain is comprised of an engine, generator, inverter, motor and battery.
