ProStar Heavy Duty Truck
When it comes to your fleet, we know what matters. Uptime, out-of-motion costs, driver satisfaction and fuel efficiency. That’s why in designing the new International® ProStar™, we set out to challenge convention and create our most advanced highway tractor ever. Five years in the making. Over 2,000 drivers, fleet managers, and maintainers interviewed. And six million miles later–the new ProStar is here. And the long haul will never be the same.

Fuel Efficiency
A REAL AERODYNAMIC EDGE
Recent wind tunnel tests demonstrated ProStar was at least 7.3% more aerodynamic than the closest competitive truck. And that will make a big difference on the road. Aerodynamic drag represents up to 50% of the road load losses for a vehicle traveling 65 mph on level ground.That means ProStar’s 7.3% aerodynamic advantage will equate to approximately 3.7% improvement in fuel economy.
Full scale wind tunnel testing was conducted at the National Research Council in Canada where SAE recommendations are followed. Testing at this facility allows for use of a trailer and the ability to rotate the truck, thereby evaluating the effects of crosswinds. Reduced cross- wind drag is where the advantage of ProStar is even more clear.

*At 65 mph, aerodynamic performance can result in 50%
of road load horsepower loss.
**Calculation assumptions: 120,000 miles annually/6 mpg = 20,000 gallons of
fuel consumed on average annually @ $4.14 gallon=
$82,800 average fuel cost annually. 3.7% savings x $82,800 = $3,000 savings.
***The over the road Type IV Tests confi rmed ProStar to
be 7% better than the Freightliner Cascadia, while the potential fuel
savings
calculation in the table above refl ects a 3.7% impact to fuel economy. The
difference in the actual over the road test is due to power-
train performance and engine regeneration.
