Features may include:

UPTIME

Diamond logic®.

  • Offering nearly 200 available body integration and driver efficiency features, the innovative and customizable Diamond Logic® electrical system maximizes productivity, safety and performance.

Over-the-air programming.

  • Allows two-way engine communication and secure wireless engine reprogramming to optimize the performance of your vehicle, all while reducing service trips and downtime.

DURABILITY

Tested and proven.

  • A wind tunnel. Six million miles on the road. Exhaustive internal testing. No detail spared to identify and address causes of downtime so you can always rely on maximum uptime.

Capable and efficient.

  • Take on any load, any distance, with the exceptional fuel economy and big bore power performance of the Cummins ISX15 engine.

Shaped To Streamline.

  • Because headwinds aren’t the only winds you’ve got to face on the road, the unique front end and cab design has the lowest wind averaged drag coefficient in the industry. It’s how you keep fuel costs low and productivity high.

DRIVER SATISFACTION

Creature comforts.

  • Enjoy quiet and comfort when driving or resting, delivered by the strategically placed engine and cab mounts. Relax as the battery-powered HVAC eliminates engine idle and feel at home with cab and sleeper storage specifically designed with the driver’s lifestyle in mind.

Knowledge is power.

  • The first of its kind for commercial trucks, the Android®-based touchscreen, vehicle infotainment system brings real-time vehicle information you want including turn-by-turn navigation, maintenance alerts and available Wi-Fi connectivity.

SAFETY

Air disc brakes.

  • An available option for both front and rear applications, air disc brakes provide shorter, surer stops, better braking feel and more braking power for improved safety. All while offering longer lining and rotor life and requiring less maintenance.

Bendix® wingman® fusion™

  • Safety is the top priority of any fleet, including yours. That's why ProStar® is first-to-market with Bendix® Wingman® Fusion™ – an advanced safety solution that combines proven Bendix safety technologies to deliver comprehensive collision mitigation.

Electronic stability control

  • Assists in both rollover and vehicle under- and over-steer situations to help maintain a vehicle's lateral stability and steerability. As well as provides drivers with improved safety and greater confidence behind the wheel during heavy and slippery surface braking applications.
