Toyota inThe 4Runner TRD Surf concept car was presented at the 2024 SEMA Auto Show in Las Vegas, creating a surprise. The concept vehicle combines additive manufacturing with a design inspired by Californian surf culture. This isn’t Toyota’s first foray into additive manufacturing: earlier this year, its Customization and Development division revealed the Hyper-F SUV concept. The latter integrates numerous 3D printed parts, demonstrating the potential of this technology in the automotive industry.
The 4Runner TRD Surf Concept pays homage to the iconic SUVs whose first generations already embodied the spirit of adventure and freedom that characterizes the 4Runner. The concept revisits the nostalgia of removable roofs, echoing the lifestyle of Southern California surfers. On this model, Toyota has pushed the limits of technology by integrating a removable 3D printed roof which combines lightness, precision and a design in harmony with the vehicle.

Additive manufacturing gives Toyota designers the freedom and flexibility to design complex parts beyond the limits of traditional methods. The roof was developed by Toyota Motorsport workshops and combinesIntegrating advanced materials and modern and classic technologies. Using CAD software and 3D printing, Toyota created a roof that was not only beautiful, but also functional, lightweight and easy to remove by one person.
For Toyota’s design team, the challenge went well beyond aesthetic innovation: it also involved rethinking functionality and practicality. The designers faced significant technical challenges, including integrating the four-door model.The SUV has been transformed into a two-door model. They also ensure that the vehicle maintains optimal performance, with or without a removable roof.
Using additive manufacturing technology, roof cut lines can be made precisely to ensure a perfect fit to the bodywork. Marty, Chief Builder and Director of Operations, Toyota Racing Technical CenterMarty Schwerter emphasizes that his ambitions go far beyond simple aesthetic or mechanical modifications. It’s about creating harmony between all the elements of the vehicle. “What is unique about this achievement is not only each modification itself, but also how they come together,” he said.

The TRD Surf Concept uses a 2.4-liter iForce turbocharged engine to deliver top-level performance. Its all-wheel drive system combined with an electronically controlled two-speed transfer case ensures responsive driving whether on the beach or on the road. Another feature of the car is a custom exhaust that creates a unique sound, consistent with the 4Runner’s “Go-Anywhere” philosophy.
