Bryan Priebe

Lead Creative Designer
Full-Size Trucks and SUVs

Bryan Priebe believes that automotive design should be nothing less than transformative for consumers, who make a considerable investment each time they purchase a new vehicle.

"What I enjoy about design is how we can improve life by finding imperfections in everyday objects that we interact with … and make objects better through design, Priebe said. "Whether it's how a person interacts with it, or finding ways to improve manufacturing processes to help make a greener product."

That's no small feat, but Priebe, a lead creative designer fo General Motors' full-size trucks and SUVs, and his team are fully up to the task, particularly when it comes to re-imagining GM's fleet of large trucks and SUVs.

Priebe, started his GM career in 2000 after graduating from the Cleveland Institute of Art with a bachelor's degree in industrial design.

In his current role as lead creative designer for the 2015 Chevrolet Tahoe/Suburban, Priebe worked with cross-functional groups like engineering and sculpting to establish the design theme for the revamped Tahoe and suburban.

That meant not only understanding the vehicles' history and heritage, but also connecting with what customers are looking for in the new versions.

"We really had to understand our customers first," he said. "We needed to know what they liked and didn't like about their vehicle and once we established that, we used this understanding as inspiration for our sketches and to develop the final theme direction."

The result, he said, is a new design that picks up where its predecessor left off.

We created a bold design with higher quality materials, technology and a better sense of refinement. This helps us to continue to lead in our segment," he said.

Priebe said he spent his childhood drawing and fixing things, which led him naturally to an interest in automotive design. Even though he spends his days in the studio, he said his inspiration comes as much from nature and human interaction as it does from industrial design and architecture.

He said one challenge he and his team encountered while working on the Tahoe/Suburban redesign was incorporating the level of refinement customers have come to expect from the vehicles while keeping it affordable.

In the end, he said, he and his committed team were able to accomplish both in the form of a re-imagined vehicle that remains true to its own heritage.

That accomplishment, Priebe said, is the result of passion and enthusiasm for good design.

"This project is a great example of what happens when a team of talented & passionate designers, engineers and sculptors work together," he said. "It is because of everyone's dedication that we have a winning design."
