Supercar Saturday in Omaha, Nebraska has announced a ban on Nissan and Infiniti vehicles equipped with the VQ V6 engine. The restriction affects the Nissan 350Z and 370Z, along with Infiniti models including the G25, G35, G37, Q40, Q50, and Q60.

This decision stems not from the engine's technical specifications, but from complaints and incidents at previous events. Organizers say that documented violations and a viral video of an accident forced them to take strict measures to ensure participant safety.

The VQ V6 is one of Nissan's most renowned powerplants, in production since 1994. It has frequently appeared on Ward's 10 Best Engines list, with versions producing anywhere from 148 to 350 horsepower in the Nismo 370Z. Yet at the Nebraska car show, the issue wasn't with the engine itself, but with the behavior of some owners.

Organizers emphasized that the ban is a temporary measure, in place at least through the 2026 season. Police will be present at events to prevent aggressive driving and dangerous maneuvers.

Against the backdrop of automakers widely shifting to turbocharged four-cylinder engines, a commitment to V6 power could serve as a marketing differentiator for the brand. However, as the Nebraska situation shows, an engine's cult status doesn't guarantee universal acceptance at local gatherings.

This episode illustrates how a model's reputation and owner conduct can impact brand perception beyond the official market. Even a legendary engine can face restrictions if event organizers deem it a source of risk. For Nissan, this isn't a blow to sales, but it highlights how automotive culture in the U.S. is becoming more regulated.
