Fuel efficiency is on the mind of every owner in the industry, which means you need a truck that won’t roll over your profits. And since wind resistance can blow as much as 50% of your fuel away, aerodynamics is the only way to stay ahead. The International® ProStar® is proven to be the most fuel-efficient truck on the road, and that means 7%* more fuel-efficient than the nearest competitor.

It’s a fact: wind swallows most of your fuel. With that in mind, International recommends the path of least resistance in ProStar, aerodynamically designed to save you money. It’s just one of the many innovations our 25 plus years of understanding aerodynamics has brought us…and you.

• Based on over the road, real-world tests, 7%* more overall fuel efficiency can translate to more than $3,700** per year per truck.
• Cab side extenders on ProStar are longer, helping to minimize aerodynamic drag between the tractor and trailer.
• ProStar’s patented pod roof fairing design is efficient in both head-on and cross-winds with its curved frontal shape.
• The chassis skirt on ProStar extends up and under cab to ensure wind flow does not get disrupted and continues to move back and along the side of the truck.

And with TMC Type IV road tests proving ProStar is the most fuel-efficient truck available; you can drive comfortably knowing that International is keeping you Miles Ahead.

* The ProStar was run competitively in TMC Type IV testing against the competition on sale in North America with ProStar outperforming the field.

** $3,700 savings based on 120,000 miles driven/year, 6mpg and $2.62 per gallon.
