The Volvo D11 is a fuel efficient, lightweight engine designed to improve reliability and minimize cost of operation.

Five power ratings are available in the range from 325 to 425 hp. The engine provides impressive performance with excellent low-end torque for improved drivability. The new variable geometry turbo also makes the engine very responsive while improving fuel economy.

A 385 Eco-torque rating provides a “dual-personality” torque level for the regional highway carrier to provide the performance of a 1450 lb-ft engine, when needed with, the fuel economy of a 1250 lb-ft torque engine.

The Volvo D11 is sold in VN Daycabs, VAH auto haulers and VHDs making it the perfect choice for regional operations.

The engine delivers competitive performance compared to larger displacement engines with an impressive 405 hp and 1,550 lbs.ft. of torque, and provides lighter solution for maximizing fuel economy in regional, less than truckload (LTL) and distribution situations.

At 1500 rpm the optional I-VEB puts out an impressive 270 braking hp, with 440 braking hp at 2200 rpm, dwarfing many bigger engines’ brake performance. The I-VEB is controlled by a new brake stalk switch, allowing three engine-brake increments.

An oil drain interval of up to 35,000 miles helps to reduce operating costs. The Volvo D11 engine delivers a dependable, cost-effective solution — for a wide variety of short haul applications.


The Volvo D13 is a very fuel-efficient, powerful and lightweight engine, designed to meet current and future EPA regulations while improving reliability and lowering operating costs.

Fourteen power ratings are available in the range from 375 to 500 hp. The engine provides impressive performance with excellent low-end torque for improved drivability. The new variable geometry turbo also makes the engine very responsive while improving fuel economy.

Two XE ratings, six Eco-Torque and three Dual-Torque ratings provide “dual-personality” torque output for those customers who desire the high fuel economy of their lower torque levels with the strong performance of their higher outputs.

The Volvo D13 is sold in VN Daycabs and Sleepers, the VHD and the VAH, making it the perfect choice for line haul, regional and vocational operations.

At 1500 rpm the optional I-VEB puts out an impressive 350 braking hp, an improvement by more than 20% over our previous engine. At 2200 rpm, it absorbs 500 hp. The I-VEB is controlled by a new brake stalk switch, allowing three engine brake increments.

An oil drain interval of up to 35,000 miles helps in reducing operating costs. The Volvo D13 engine delivers a reliable, cost-effective and powerful solution in a light, high-performance package, for a wide variety of applications.

More savings for more applications.

The Volvo D13 Turbo Compound engine now offers fuel savings for a wider variety of applications than ever before. Fleets that run variable load applications, including tanker, bulk haul and flat-bed deliveries, can benefit from Volvo’s next-generation Turbo Compound system.

Energy is recaptured by the Turbo Compound unit from the engine’s exhaust gas. The extra power captured by the TC is returned to the drive train. The Volvo integrated driveline then uses extreme downspeeding to maintain road speed at lower RPM, saving even more fuel.

The D13 with Turbo Compounding is available from 405-455 hp with up to 1,850 lb-ft. of torque. The engine is available in nine different ratings and can be selected in a High Torque, Economy, Adaptive Gearing or Superdirect configuration. These engines work together with the Volvo I-Shift for maximum efficiency and performance by utilizing peak torque down to 900 RPM.


With ratings from 400-500 hp, and 1450-1850 lb-ft of torque, the X15 Efficiency Series is well suited for fleets in freight applications that require fuel economy and the benefits of bigger block architecture. The economy-focused engine is optimized to deliver peak torque at lower engine speeds and enable down-speeding without compromising driveability.


As the fueling infrastructure for natural gas becomes increasingly plentiful, more and more delivery, distribution and regional fleets are seeking to leverage the benefits of this fuel. Dedicated, factory-built, natural gas engines, the Cummins ISL G and ISX12 G are proven alternative-fuel solutions.


Say goodbye to missed gears, sticky clutches and lousy fuel mileage. With I-Shift, you’ll always be in the right gear at the right time.

Volvo I-Shift is a 12-speed, two-pedal, automated mechanical transmission that maximizes driver comfort, payload and fuel economy. It’s designed to integrate seamlessly with all Volvo engines. There’s no clutch pedal, and the gearshift is operated by intelligent electronics.

Using microprocessor technology, I-Shift continuously monitors changes in grade, vehicle speed, acceleration, torque demand, weight and air resistance. With the engine and transmission in constant communication, there’s no compromising. I-Shift automatically selects the best gear for the engine, allowing every driver to shift like a fuel-efficiency expert. This puts less stress on the driveline, for longer life and less maintenance.

Volvo engines do a superb job of keeping fuel temperature regulated, allowing them to operate more efficiently for better fuel economy and lower operating costs.

Engine fuel systems are divided into low- and high-pressure zones. The low-pressure zone filters and supplies fuel to the high-pressure zone, which injects fuel into the cylinders. The cam actuates the injector plunger and produces the high pressure needed to inject atomized fuel for an efficient burn. The fuel injector solenoid valve allows the fuel to be injected or bypassed.

Injectors feed fuel to the engine based on volume. Heated fuel is less dense (less BTU per volume), and therefore, engine performance decreases as fuel temperature increases. Addition of fuel coolers-which also add cost and complexity-can compensate for the increased heat.

Volvo engines do not require fuel coolers. Our system draws fuel from the tank through a 20-40 micron primary filter. It then passes through and cools the ECU as it heads toward a fuel exchange at the top front of the engine cylinder head. At that connection, excess fuel from the injectors is mixed with the incoming fuel and pumped through a 3-5 micron secondary filter. The fuel is then sent to the injectors at the rear of the cylinder head.

Because our system draws only the amount of fuel needed for combustion, the fuel temperature is not increased with large amounts of return fuel. The recirculated fuel’s temperature is maintained by engine coolant, which has better regulation than return fuel.
