The 2025 SEMA Best Engineered Vehicle of the Year Award was presented to Kyle Kuhnhausen from Kuhnhausen Metal Concepts at the 2025 SEMA Show for his meticulously reimagined '66 Chevrolet Corvette. Nicknamed Serious 66, the Corvette was selected for exemplifying innovation, integration and engineering-first thinking.
Designed to spotlight the critical role engineers play in shaping the future of the automotive aftermarket, the SEMA Best Engineered Vehicle Award honors a SEMA Show feature vehicle that goes far beyond visual impact. Entries for the 2026 award are open now. Submit your entry here.
The winning Corvette stands as a masterclass in resourceful, systems-driven engineering. Rather than relying on a single standout feature, the vehicle reflects a holistic approach where hundreds of engineered components work seamlessly together. Advanced processes such as 3D scanning, reverse engineering, CAD, fluid dynamics analysis, laser cutting, vacuum-formed composites, additive manufacturing and CNC billet machining were strategically combined to achieve efficiency, precision and cost control without compromising quality.
Material science played a key role as well. Titanium was used to reduce intake temperatures thanks to its low thermal conductivity, while chromoly steel provided increased stiffness with reduced weight, preserving torsional rigidity throughout the chassis. Much of the vehicle's most impressive engineering is intentionally hidden, including integrated fuel and oil lines, aerospace-grade plumbing, concealed electrical service panels and a highly sophisticated cooling system packaged throughout the vehicle's body structure.
Among the most notable breakthroughs is the drivetrain: a dry-sump, direct-injected LT4 paired with a ZF 8HP70 transmission, one of the first street-proven executions of this combination, complete with electronically actuated manual control. Careful packaging and simulation also enabled race-inspired weight distribution, delivering exceptional balance, grip and drivability.
This Corvette is not defined by a single innovation, but by the way every system works together--quietly, efficiently and intentionally. That cohesion is the hallmark of truly exceptional engineering, and a fitting recipient of the 2025 SEMA Best Engineered Vehicle of the Year Award.
Does Your Build Have What It Takes to Win?
Entries for the 2026 SEMA Best Engineered Vehicle of the Year Award are now open to builders exhibiting a feature vehicle at the 2026 SEMA Show, November 3-6, that demonstrates engineering excellence.
Entries should demonstrate technical excellence, innovative design and creative problem-solving that advances vehicle performance, functionality, safety or overall capability.
To be considered for the award, builders must upload a photo, video and description of the build's engineering content, along with the location of the displayed vehicle at the SEMA Show. Entries are being accepted through Wednesday, October 28, at this link.
The winner will be announced at SEMA Central on Thursday, November 5, and will receive a commemorative trophy.
