IndyCar’s new IR-28 heads onto the Indianapolis Motor Speedway oval for the first time today, while Formula 1 prepares for its first Madring weekend and MotoGP arrives at Misano with just 19 points separating the top two in the championship.
Elsewhere, the BTCC title fight tightened further at Croft, the British Superbike Championship is building towards Assen, Christopher Bell has finally broken through in NASCAR’s Chase and Ferrari has blown the FIA World Endurance Championship battle open with a dramatic victory at COTA.
Here is the Tech Torque Media Motorsport Daily round-up for Wednesday, 9 September 2026.
IndyCar IR-28 faces its first oval test at Indianapolis
The most technically significant story of the day comes from Indianapolis, where the new IR-28 begins its first oval validation test on Wednesday and Thursday.
Alexander Rossi is scheduled to drive on Wednesday before five-time IndyCar champion Alex Palou takes over on Thursday. It is the second on-track validation test for the all-new car following road-course running at Indianapolis Motor Speedway last month.
The IR-28 is due to make its competitive debut at the start of the 2028 NTT IndyCar Series season and represents a substantial rethink of the current platform. IndyCar says the new car will be approximately 100lb lighter, with its aerodynamic architecture specifically designed to reduce the disadvantage suffered by cars running in another car’s wake.
That makes this oval test particularly important. Indianapolis is where the combination of weight, drag, stability and wake behaviour is exposed most severely, and IndyCar has already stated that the new package is intended to deliver greater speed while allowing drivers to race more closely.
The wider 2028 package also includes a new 2.4-litre twin-turbocharged V6 and next-generation hybrid system. IndyCar’s technical outline of the IR-28 describes a cleaner speedway aero package, lighter aeroscreen and revised suspension system alongside the reduction in overall mass.
For now, outright lap time is only part of the job. Engineers will be looking closely at balance, stability, cooling and aero behaviour in speedway trim before the development programme expands further. It is a very different kind of IndyCar story from Sunday’s season finale, when Scott McLaughlin ended his two-year win drought at Laguna Seca.
Formula 1 turns its attention to Madring
Formula 1 barely has time to digest Monza before another major unknown arrives this weekend. The championship moves to Madrid for the first Grand Prix at Madring, with opening practice scheduled for Friday, 11 September.
Kimi Antonelli arrives with a 66-point advantage over Mercedes team-mate George Russell after winning the Italian Grand Prix at Monza, but the new 22-corner Madring layout gives every team a fresh engineering problem. The official Formula 1 event page lists a 5.416km circuit combining public roads and private land, with 57 laps scheduled for Sunday.
The biggest question is not simply who has the quickest car, but which team gets on top of a new circuit fastest. Simulator correlation, track evolution, tyre behaviour and setup direction will all matter from the first laps of FP1.
We have already covered the circuit, championship picture, La Monumental banking, tyre expectations and weekend schedule in our full 2026 Spanish Grand Prix preview. For today’s round-up, the key point is simple: after a Monza weekend that strengthened Mercedes’ position, Madrid immediately asks a completely different question of the 2026 cars.
MotoGP heads to Misano with 19 points covering the top two
The MotoGP paddock arrives at Misano this week with the title fight finely balanced. Jorge Martín takes a 19-point championship lead over Marc Márquez into the San Marino Grand Prix, according to MotoGP’s official weekend schedule.
That margin is the direct consequence of another strong Aragón weekend for Márquez. Our Aragón Grand Prix report covered how his victory reduced Martín’s advantage to 19 points, giving Misano immediate championship significance.
Misano is Round 14 of the season, and with the title contenders now separated by less than a single Grand Prix win, every Sprint and Sunday race result carries extra weight. The next step is Thursday’s media activity before track action begins on Friday.
BTCC: Sutton edges closer after a dramatic Croft weekend
Croft delivered three different winners in the BTCC, with Josh Cook, Ash Sutton and Mikey Doble all taking victories across Sunday’s races.
The bigger championship story is that Sutton survived a difficult day for several title contenders and still extended his advantage. BTCC’s official Croft review puts Dan Cammish 115 points behind the NAPA Racing UK driver, with reigning champion Tom Ingram another eight points further back.
Doble’s race-three win was his third career BTCC victory and also strengthened his position at the top of the Independent Drivers’ Championship. With the season moving deeper into its decisive phase, Sutton is increasingly in control of the overall picture, but Croft again showed how quickly race-day setbacks can reshape individual results.
BSB: Scott Swann gets Assen wildcard with TAG Racing Honda
The British Superbike Championship has a little longer before its next race weekend, but there is fresh movement ahead of Assen on 18–20 September.
TAG Racing Honda has confirmed Scott Swann for a one-off British Superbike appearance at the TT Circuit Assen. The 23-year-old Northern Irish rider currently sits third in the Pirelli National Superstock Championship and has taken two victories this season.
Swann will complete a one-day shakedown at Donington Park before travelling to Assen. It is a useful opportunity for both rider and team, and adds another storyline to a round that already carries plenty of championship importance.
NASCAR: Bell finally wins as the Chase moves to Gateway
Christopher Bell could hardly have picked a better time to end his wait for a victory. Bell won the opening race of the 2026 NASCAR Cup Series Chase at Darlington after a season that had already included seven runner-up finishes.
According to NASCAR’s post-Darlington Chase report, the victory ended a 33-race win drought and moved Bell four places up the standings.
The championship now heads to World Wide Technology Raceway at Gateway for Sunday’s Enjoy Illinois 300. After one race, the key lesson is already familiar: consistency matters, but a win at exactly the right moment can transform a driver’s postseason position in a single afternoon.
WEC: Ferrari victory at COTA blows the title fight open
The most dramatic result of the past few days arguably came in the FIA World Endurance Championship, where Ferrari’s #50 499P won the Lone Star Le Mans at Circuit of The Americas after Toyota’s #7 car suffered a late hydraulic problem.
The Toyota of Nyck de Vries, Kamui Kobayashi and Mike Conway had looked set for victory until de Vries was forced to retire with around ten minutes remaining. That handed the lead to Miguel Molina, Antonio Fuoco and Nicklas Nielsen in the #50 Ferrari.
The official FIA WEC race report confirms Cadillac finished second with Alpine third, while the result left de Vries, Kobayashi and Conway level at the top of the Drivers’ standings with BMW pair René Rast and Robin Frijns.
Ferrari’s first victory of the 2026 campaign also pulled the manufacturer firmly into the championship battle. With Fuji next on 25–27 September, COTA has changed the complexion of a season that had been threatening to tilt towards Toyota and BMW.
What to watch next
- IR-28 oval feedback: Rossi’s first speedway running should give IndyCar its clearest evidence yet of how the new chassis behaves in Indianapolis trim.
- Madring preparation: Formula 1 teams now have only two days before the first official practice session at a completely new venue.
- MotoGP media day: Martín and Márquez arrive at Misano separated by only 19 points, setting up another high-pressure weekend.
- Championship momentum: Sutton in BTCC, Bell in NASCAR and Ferrari in WEC have all strengthened their positions or changed the direction of their respective title battles.
Tech Torque Verdict
The IR-28 test is the biggest story in today’s round-up. IndyCar is looking well beyond the current season, and this week’s running at Indianapolis is an important step in proving whether the new car can deliver the closer racing, lower weight and improved stability the series is aiming for from 2028.
For Formula 1 and MotoGP, the interest is much more immediate. Madring gives every F1 team a fresh technical problem straight after Monza, while Jorge Martín and Marc Márquez head to Misano separated by just 19 points.
WEC has its own title twist after COTA, with Ferrari’s win pulling the manufacturer further into the fight, while BTCC and NASCAR are both entering the stage of the season where every dropped point starts to hurt.
Taken together, it makes for a busy few days across the major series. The IR-28 test is the one to watch today, but by Sunday the bigger talking points could just as easily be coming from Madrid, Misano or Gateway.
