Autocross from the 2017 NSRA Street Rod Nationals

The Streetkhana autocross has become a fixture of the NSRA Street Rod Nationals, turning a corner of the Kentucky Exposition Center into a timed slalom course for hot rods built decades before autocross existed. Introduced in 2016, the format tests driver skill with hairpins, switchbacks, and speed-gathering straights, awarding fastest pre-1949 and post-1949 cars. What began as an experiment has become an annual tradition.


In 2016, the National Street Rod Association went against their home-grown grain and took a chance and introduced autocross, or as they call it here, Streetkhana, action to the their largest car show of the year: The NSRA Street Rod Nationals. Not knowing quite what to expect that first year, the rowdy g-Machines caused plenty of tire-squealing commotion on the north side of the fairgrounds while dodging cones, smoking tires, and having a whole bunch of fun. Needless to say, the NSRA approved and have since made it a regular attraction to this event and a few others throughout the year.

Picture a parking lot at the Kentucky Exposition Center suddenly transformed into a slalom course, with pre-war roadsters and shoebox Fords carving around cones instead of cruising the show field. That is the scene the National Street Rod Association created when it added the Streetkhana to its biggest event of the year, and it caught plenty of traditionalists off guard. Street rodding had always been about polish and pedigree — paint, chrome, and trophies for craftsmanship — not lap times. So when hot rods that had never seen a cone before started throwing tire smoke on a timed course, it raised an obvious question: how would a community built on Sunday cruising take to genuine competition?

A Course Built to Test Nerve, Not Just Horsepower

The Streetkhana course at the Nationals combines slaloms, a couple of tight hairpins, switchbacks, a sweeper, and speed-gathering straights, forcing drivers to manage momentum in cars that were never engineered with modern suspension geometry in mind. Unlike a typical parking-lot autocross, the layout is deliberately scaled up, giving each run a longer, more demanding rhythm that rewards smooth inputs over brute throttle. For owners used to polishing chrome for a concours judge, learning to read cone placement at speed is a different kind of skill entirely.

Awards are handed out for the fastest pre-1949 vehicle, the fastest post-1949 vehicle, and a separate vendor’s choice recognition, a structure that lets everything from a Depression-era coupe to a resto-modded tri-five Chevy compete on its own terms rather than against cars from a completely different era.

From One-Off Experiment to Annual Tradition

When the NSRA first tried the format in 2016, nobody was quite sure how it would be received; the rowdy g-Machines running the course caused plenty of tire-squealing commotion on the north side of the fairgrounds while dodging cones and smoking tires. The reaction was enthusiastic enough that the NSRA made Streetkhana a regular fixture, not just at the Street Rod Nationals but at several other events throughout the year, cementing autocross as a legitimate part of street rodding rather than a novelty sideshow.

The 2017 event, held August 3 through 6 at the Kentucky Exposition Center in Louisville, folded the Streetkhana into a schedule already packed with car corrals, swap meets, and manufacturer displays — proof that a hobby built around Sunday cruising had room for a little organized chaos, and that hot rodders were more than happy to prove their machines could do more than look good standing still.
