International’s ProStar highway tractor
International’s ProStar highway tractor
Investing $300 million in development and collaborating with dealers and customers, International Truck and Engine Corp. in March unveiled ProStar – a new line of aerodynamic Class 8 tractors. The truck maker says the ProStar was designed to excel in four basic areas: fuel economy, driver satisfaction, uptime and low ownership cost.
“The new International ProStar will turn heads on the highway and at the pumps,” said Tom Baughman, vice president and general manager of the company’s Heavy Truck Group. “Owners will love the way this truck saves money and generates profits, and drivers will love the drivability and comfort we’ve packed inside.”
Sculpted fenders, a sloped hood and streamlined cab and roof shaping form the core of the ProStar’s aerodynamics. International’s development team used computational fluid dynamics and one-eighth scale wind tunnel testing for basic shape development. Full-scale wind tunnel testing with a trailer attached revealed an 8 percent drag reduction improvement compared to International’s previous best-performing model.
In the area of driver satisfaction, developers focused on improving the ergonomics and comfort by taking detailed measurements of numerous truck drivers. Among the features International touts are massaging seats; flexible positioning of steering wheels and instrumentation; and roomier, better-lit sleeper berths. The tractor also offers superior noise and vibration suppression, International said.
“The integrity and durability of the new International ProStar cab delivers a smoother, quieter ride, minimizing driver fatigue and maximizing productivity,” Baughman added. Designers from International’s Fort Wayne Truck Development and Technology Center slept in a variety of tractor sleepers and traveled with drivers throughout the development program to better understand their requirements for living and sleeping space utilization.
To optimize productivity and uptime and reduce lifecycle costs, developers looked closely at actual fleet experience, Baughman said. “We spent a lot of time with customers mining their maintenance records and discussing the top causes of downtime,” said Baughman. “Every targeted system improvement has been tracked ongoing, from component testing through to vehicle testing.”
Responding to top causes of downtime – such as tires, electrical harnesses, connectors, batteries, air leaks, air brakes and fuel systems – International developed monitoring, prognostic and diagnostic systems to improve uptime performance and provide information to drivers and fleet managers.
Once of the major goals was reducing the time for maintenance and repairs. For example, transmission time has been reduced by 90 minutes, and headlight bulbs and windshield wiper blades can be replaced by the driver without tools, the truck maker says. The tractor also features a low-effort E-Z Tilt hood and Tilt-Away bumper to provide a walk-in engine compartment and allow easy engine and underside access. And International synchronized service intervals for an average of 59 more days on the road over the life of the vehicle.
More than 25 production validation tractors have accumulated more than 6 million miles of road testing since late 2004, including customer test units and internal test vehicles, International said.
Initial production of the ProStar will be based on a 122-inch BBC tractor with daycab and high-rise sleeper configurations. The second phase of production will include additional BBC and sleeper configurations. Shipments of the ProStar to dealers are scheduled to begin in the first quarter of 2007.
