Sam Russo didn't plan to compete in the Rebelle Rally. Then she turned to a friend at a conference and said "we should do this" — and the rest, as they say, was chaos in the best possible way. In this episode of BeDifferential, Sam talks about how a moment of "say yes to the crazy" energy led her to prep a high-mileage 4Runner, build navigation skills from scratch, and so much more before going into the desert. Now returning for 2026 with a new co-driver partnership alongside Lacy Taylor, Sam breaks down what the Rebelle Rally actually is — 8 days, no GPS, no speed component, just maps, compass, roadbooks, and teamwork across some of the most demanding terrain in the American West. The 11th edition launches from Las Vegas Motor Speedway for the first time ever and adds Utah to the route, running October 7–17, 2026. We also get into why the Rebelle has become such a powerful rallying point for women in the automotive aftermarket — and what Sam wants to prove to herself by the time she crosses the finish line.Be sure to subscribe to our newsletter so you never miss a thing!https://www.bedifferentialpodcast.com/This episode is sponsored by KNIPEX.

Formula 1 opens a brand-new circuit in a European capital this weekend, which is a thing that basically never happens. The Spanish Grand Prix moves to Madrid — the Madring — and it's the first F1 race in the Spanish capital since Jarama in 1981. Forty-five years.But the part I can't stop thinking about isn't the track. It's the contract.Three weeks ago Zandvoort hosted its last Grand Prix because its promoter — privately funded, sold out five months early — chose not to renew. Madrid just signed for ten years. Same sport, same era, opposite decisions. And the reason why explains more about modern Formula 1 than any track guide will.Here's the number that made it click: the circuit cost roughly €83 million to build. The hospitality partner has committed around €400 million over ten years. The hospitality operation is worth about five times the racetrack.Also in this one: what the Madring actually is (a hybrid — about 2.2km of purpose-built track stitched to real city streets, with two tunnels), and La Monumental, the 548-metre, 270-degree banked corner that's now the longest corner in Formula 1. Banked at 24%, twelve metres wide, and blind over a crest. Nobody knows yet whether it'll be flat out.Zandvoort couldn't make six years work. Madrid signed for ten. Is that Formula 1 fixing its problem — or just moving it somewhere the taxpayer pays?I argue it both ways and genuinely don't land on one.

Charlie Wiggins was a four-time Gold & Glory Sweepstakes champion who built his own race car, ran a thriving mechanic shop on Indiana Avenue in Indianapolis, and achieved things that should have made him a household name in American motorsports. Instead, his story was nearly lost entirely. In this episode of BeDifferential, former GM Vice President of Global Design Ed Welburn — the man who has spent years championing Charlie's legacy — joins us to tell it in full. Ed traces how he first encountered Charlie's story, what it took to decide this was something worth doing rather than just worth knowing, and what the recovery of the original Wiggins Special — unseen publicly for over 90 years — meant to him personally. As guest curator of For Gold & Glory, a world premiere exhibition opening September 19th, 2026 at LeMay — America's Car Museum in Tacoma, Washington, Ed also shares what it takes to tell a story this layered through objects, imagery, and space — and why the centennial of Charlie's first championship made this the moment to do it. The exhibition opens September 19th. Tickets and details at americascarmuseum.org/ForGoldandGlory.This episode is sponsored by KNIPEX. Learn more at https://www.knipex-tools.com/

NASCAR quietly rebuilt its entire playoff format for 2026 and almost nobody covered it. Then on Saturday night at Daytona, it produced the exact result it was designed to prevent.Here's the change: the knockout rounds are gone. No more three rounds of three and a winner-take-all Championship 4. It's a ten-race Chase — the first since 2013 — with one points reset and no eliminations. And "win and in" is abolished. The field is set purely on regular season points.Which is why what happened at Daytona is so strange. Ryan Preece went into the last race of the regular season 31 points below the cutline, won it in overtime with a last-lap pass, and made the playoffs — but not because he won. Winning doesn't do that anymore. He got in on points, and he needed every single one of them. Meanwhile the driver he passed had a 31-point cushion, won the opening stage, and lost his season on a pit call.So the rule worked exactly as designed and changed nothing. I get into why that's more interesting than it sounds, and why the new format didn't make Daytona calmer — it made it crueler.Also: the Southern 500 opens the Chase this Sunday, Alex Palou wrapped up a fourth straight IndyCar title, and Milwaukee ran race two before race one because of the weather.A driver 31 points below the cutline won at Daytona and made the playoffs anyway. Did NASCAR fix its format — or just make the same thing happen through a different door?Tell me where you land.The Thursday Pit Stop, from the Be Differential podcast.

Christian Valverde grew up with Silverstone as a backdrop — and at 18, he's already closer to that world than most people ever get. In this episode, Christian talks about nearly a decade of competitive karting across four countries, four championship titles, and what it actually felt like to finish school without a clear path but with an unshakeable ambition. Now competing in the 750 Motor Club MX-5 Cup Championship, he breaks down what his week looks like right now — instructing at Drive Silverstone, coaching at Kart Silverstone, interning at iZone Driver Performance, and racing, all at the same time. He gets into what telemetry and data analysis have taught him about his own driving, what shifted between Race 1 and Race 3 at Snetterton, and why coaching other drivers while still developing yourself is more complicated than it sounds. We also get honest about the financial reality of building a motorsport career without a traditional pathway — and what he'd tell any young person who loves racing but doesn't know where the door is.Be sure to subscribe to our newsletter so you never miss out! https://www.bedifferentialpodcast.com/Follow along on Christian's journey on Instagram @christian_valverde1 and his website, https://valverdemotorsport.com
