Shell Starship 3.0 Enters Real-World Action in IndyCar

The Shell Starship 3.0 has officially transitioned from a concept vehicle to a fully operational big rig, demonstrating its capabilities in the real world. This innovative truck is now responsible for transporting the Pennzoil Technical Inspection Trailer throughout the 2025 IndyCar Series, marking a significant step in its operational journey. Shell emphasizes that this isn't merely a showcase for sustainability; the Starship 3.0, powered by the Cummins X15N natural gas engine, is performing with real-world efficiency metrics that validate its design and functionality.

As it traverses the paddocks not just at the iconic Indy 500 but across the entire IndyCar circuit, the Starship 3.0 is set to make a lasting impact in the realm of sustainable transportation.

Efficiency and Practical Application: The Core of Starship 3.0

Launched in 2018, the Starship initiative was designed to challenge conventional thinking in trucking. By merging existing technologies into a single long-haul truck focused on maximizing fuel efficiency, Shell aimed to address the pressing issues faced by modern fleets. As Tom Mueller, Shell's general manager of commercial road lubricants, explained, the initiative was a response to the industry's increasing demands for cost-effectiveness and environmental responsibility.

During a recent test run in 2023, the Starship 3.0 successfully completed a journey of 890 miles while carrying a gross vehicle weight of 80,000 lbs. Throughout this trip, it achieved an impressive average of 9 miles per gallon in diesel-gallon-equivalent, showcasing the potential of natural gas as a viable fuel alternative in heavy-duty trucking.

Designed for Maximum Efficiency

The design of the Starship 3.0 prioritizes aerodynamics and weight reduction, essential factors for improving fuel economy. With features like camera-based mirror systems, a streamlined curved nose, and a lightweight chassis, this truck is engineered for optimal airflow. Although the current version is fitted with a specific refrigerated trailer for its operational duties, many of the original efficiency-enhancing modifications remain intact.

Scott Burian, Shell's global integrated communications manager, highlighted several key design elements:

• Airflow management through skirts and aerodynamic enhancements on the rear
• Solar panels on the roof to power various electric systems
• Automatic closing air gap sealers, although these have been temporarily removed for the refrigeration unit

While the refrigeration feature may impact certain aerodynamic enhancements, the conversation around trailer aerodynamics is gaining traction, with many other fleets and original equipment manufacturers (OEMs) beginning to adopt similar innovative strategies.

Diverse Fuel Options: Beyond Natural Gas

Shell's exploration of sustainable fuel alternatives extends beyond natural gas. A variant of the Starship project in China employs a diesel hybrid powertrain that operates on biofuel, developed in partnership with OEM FAW Jiefang. This initiative shares the same overarching goal: to leverage existing technologies to minimize emissions and enhance operational efficiency.

Burian emphasizes that the essence of the project remains constant: “Try it, measure it, and see how it works on the road.” This iterative approach allows for real-time data collection and analysis, leading to continuous improvements in performance and sustainability.

The Importance of Fluids in Performance

Inside the Starship 3.0, the engine and drivetrain utilize Shell's advanced lubricants specially formulated to optimize performance in natural gas platforms. The selection of fluids includes:

• Shell Rotella ELC HD coolant for superior temperature management
• Shell Gadus grease, essential for effective chassis lubrication
• Shell Spirax transmission fluid for enhanced gearbox efficiency
• Shell synthetic 5W-30 engine oil from the Engine Plus line, specifically developed for natural gas engines

As Burian points out, while these components may not be visible under the hood, their roles are critical to achieving operational efficiency. Without these advanced lubricants, the vehicle would struggle to perform at optimal levels.

Shell Starship 3.0: A Piece of a Larger Sustainability Strategy

In the context of the IndyCar Series, the Starship 3.0 represents a significant commitment to sustainability. Shell's involvement extends beyond the truck itself; the company also provides renewable racing fuel for the series, reinforcing its dedication to cleaning up both the racing and support sides of the event.

Burian notes, “This started as a successful proof of concept, and now it’s actually working.” The advancements seen in the Starship 3.0 are likely to influence future truck designs across the industry, paving the way for more environmentally friendly transportation solutions.
