Fuel consumption and exhaust emissions

In this chapter:

Operating costs for customers include driver salaries, fuel costs, vehicle capital costs (depreciation and interest), service and insurance. Fuel accounts for one of the highest costs for all customers and any measure that can reduce fuel consumption will help to improve profitability while reducing environmental impact.

Fuel-saving potential

The estimated fuel savings for a standard Volvo truck will be 15 percent greater in 2025 compared with fuel consumption in 2010. This can be achieved by further improving the driveline, design, weight and tires and adding new technology. Below are different examples of activities and features with significant fuel-saving potential. It is not possible however to add all the figures together.

-5%

Intelligent cruise control

Intelligent cruise control -5%

I-See is a new feature where the truck learns the topography of the road and memorizes the curves and slopes. The next time it drives along the same road it adapts automatically the brakes and gears in the most optimal way. This new technology can save up to 5% fuel.

-5%

Fuel efficient driving

Fuel efficient driving -5%

As an alternative to intelligent cruise control, a driver trained in fuel-efficient driving can lower the fuel consumption by 5% to 10%.

-5%

Design

Design -5%

Improving the cab and trailer design can reduce air resistance and contribute to a fuel saving of 5 to 10%.

-15%

25.25 meters

25.25 meters -15%

With a vehicle length of 25.25 meters instead of the current 18 meters in the EU, three truck-trailer sets can be replaced by two. EU-level legislation permits longer vehicles, but the legislation has not yet been implemented in all EU countries.

-5%

Low weight

Low weight -5%

Thanks to a weight-optimized design, each vehicle can carry higher loads.

-5%

Side spoilers

Side spoilers -5%

Adding side spoilers can contribute to reducing air resistance.

-5%

Tires

Tires -5%

Low rolling resistance tires can affect the fuel consumption by up to 5%.

-4%

Efficient engines

Efficient engines -4%

Euro VI engine combined with the I-Torque technology has a fuel saving potential by up to 4%.

The estimated fuel savings for a standard Volvo truck will be 15 percent greater in 2025 compared with fuel consumption in 2010.

The estimated fuel savings for a standard Volvo truck will be 15 percent greater in 2025 compared with fuel consumption in 2010. This can be achieved by further improving the driveline, design, weight and tires. New technology can be used to achieve more significant savings. For instance, the use of a hybrid driveline in a truck has a fuel saving potential of 15–20 percent in distribution applications. For certain city bus operations the fuel saving potential is up to 39 percent.

IPS propulsion system for boats

Volvo Penta’s Inboard Performance System (IPS) is a propulsion system that reduces fuel consumption by up to 30 percent at cruising speed compared to conventional technologies. In total over 14,000 IPS units have been delivered worldwide, mainly in leisure applications, but is now also becoming an important propulsion alternative in commercial applications to save fuel and reduce environmental impact with regard to exhaust emissions and noise.

The IPS propulsion system selected by the Swedish Coast Guard in 2012 already meets the EPA marine Tier 3 emission regulation which will come into effect in 2014.
