ISX15 for Heavy-Duty Truck (2013)

Overview

ISX15 for Heavy-Duty Truck (2013)

Cummins ISX15 is North America’s most popular heavy-duty engine, and the only engine offered as an option by every major Class 8 truck manufacturer. The ISX15 boasts ratings from 400-600 horsepower with up to 2050 pound-feet peak torque. This legendary engine is a favorite among drivers and fleet operators alike.

Here’s why ...

Fuel Economy

The ISX15 is the industry leader in fuel economy. In 2013, we refined our proven technology, including more efficient fuel and water pumps to provide additional usable horsepower. Together with optimized combustion and fewer active regenerations of the aftertreatment system, today’s ISX15 delivers up to 2% better fuel economy.

Durability

Each element of the ISX15 is manufactured to maximize fuel economy, performance and durability, while delivering the lowest operating costs of any engine in its class. Integration and optimization of every system from air handling to exhaust aftertreatment results in the most reliable engine on the road.

Performance

ISX15 ratings range from 400-600 hp (298-447 kW) with up to 2050 lb-ft (2779 n•M) of peak torque. These include SmartTorque ratings that add 200 lb-ft of extra torque in the top two gears so Class 8 trucks can make it up steep grades with fewer downshifts. Vocational ratings have additional torque in the lower gear ranges. Operators can tailor ISX15 operation for any on-highway application using Cummins PowerSpec.

Emissions

The ISX15 was the first engine certified to meet 2014 Environmental Protection Agency (EPA) and Department of Transportation (DOT) regulations – a full year ahead of schedule. The Model Year 2013 ISX15 is equipped with On-Board Diagnostics (OBD) to ensure optimal emissions system performance.

Warranty

Base engine warranty coverage for the ISX15 includes parts and labor on warrantable failures for both the engine and aftertreatment system with no deductible. Extended Coverage Plans are available for the base engine with options for up to 7 years or 500,000 miles (804,672 km). Extended coverage plans are also available for the aftertreatment system and major components. Check with your Cummins distributor or dealer for details.
