They're Racing Inside an Active U.S. Navy Base. This Is the Craziest Street Circuit NASCAR Has Ever Attempted. LIVE THIS WEEKEND

Brad Keselowski walked the circuit and summed it up in one sentence: "It's very much going to be a survival race." That's not hyperbole. The Anduril 250 at Qualcomm Circuit on Naval Base Coronado in San Diego is genuinely unlike anything NASCAR has attempted before — and NASCAR's been trying some wild stuff lately.

We're talking 3.4 miles of temporary asphalt through an active U.S. Navy base. Railroad crossings mid-lap. Sections just feet from San Diego Bay. Some corners barely wide enough for two cars side-by-side, immediately followed by wide sweeping S-sections that feel like a completely different circuit. Oh, and 19 turns total — enough blind spots that teams are requesting more corner workers than any NASCAR event in memory. Three dozen corner workers minimum.

Practice runs today, June 19. The Anduril 250 Cup Series race goes green Sunday, June 21 at 4:00 PM EDT on Prime Video.

Why This One Is Different

NASCAR has done the Chicago Street Course. They've raced at COTA, Sonoma, Watkins Glen. But Naval Base Coronado is in another category entirely. This isn't a city street repaved for racing — it's an active military installation. Camping is prohibited for obvious reasons. Fans can attend, but military members get first access on Friday. The circuit crosses actual railroad tracks used by the base.

The track surface is rough in multiple sections — rough enough that teams are worried about flat tires and rear diffuser damage from bumps and low spots. Stack that on top of 19 corners with blind exits, and you start to understand why Keselowski isn't joking about "survival race."

For performance car enthusiasts, this is worth watching from a pure engineering perspective: How do NASCAR Cup cars — built for ovals and mixed-surface superspeedways — handle a bumpy, technical, stop-and-go street layout? The suspensions will be tested. The brakes will cook. Aero efficiency is out the window. It's going to come down to mechanical grip, tire management, and driver instinct.

The Stories to Follow

Kevin Magnussen making his NASCAR Cup debut — the ex-Formula 1 driver joins Trackhouse Racing's Project 91 entry, following in the tire tracks of Kimi Räikkönen, Helio Castroneves, and Shane van Gisbergen. Magnussen has never raced in any level of NASCAR before. F1 vet going street circuit for the first time in a stock car? Must-watch.

Jimmie Johnson racing at home — the 7x champion is a California native doing double duty this weekend at a circuit in his home state. Sentimental story, serious talent.

And of course, SVG himself — Shane van Gisbergen, who already knows how to win NASCAR street races (he did it in Chicago). Watch the video above where he walks through the trickiest sections of the Naval Base Coronado layout. This is the kind of insider track knowledge that makes the difference between finishing and folding on race day.
