2025 was a year full of emotion and hard work. A lot has happened at the factory and with the car. David Hosie, who designed the Rush SR and co-founded this company with his son Blair, passed away in 2025. He was a father to Blair, and like a father to me and the rest of the paddock. He built something that will outlast him. A race car that people love driving, can live with, fills huge grids, and keeps improving. Everything we build is an extension of what he started.
New Assembly Line
In mid-2025 we put in a revamped assembly line at our Houston facility. The transition was disruptive. September and the first half of October saw lower output than we wanted, but we have successfully ramped to 15-20 cars a month. The line is running now. Cars coming off it are built to tighter tolerances with more consistent assembly. If you have an older car, the fundamental design has not changed. It is just built more precisely. Current lead time is 3 to 5 months and it is coming down. 300+ cars delivered. If you have been waiting on availability, now is the time to get on the list.
Gen3 Fuel Cell
This is the most important update for current owners. All new Rush SRs ship with the Gen3 6-gallon fuel cell. It is a revised design that mounts behind the seat and is approved for NASA, SCCA, SVRA, and GridLife. GridLife allows the existing side configuration (blue ATL tank) for 2026. NASA, SCCA, and SVRA require the Gen3 cell. Retrofit cost: $3,150. Installation runs 14 to 18 hours. If you are racing outside GridLife in 2026 with a pre-2026 car, this is not optional. Call your dealer to schedule an install.

Öhlins Shocks
We announced a strategic partnership with Öhlins Racing. Öhlins has over 460 world championship titles and supplies suspension to Formula 1 and MotoGP teams.
We spent time at their North Carolina facility on the shaker rig (the same equipment used for high-level motorsport development), mapping the Rush SR’s suspension package and dialing in valving. Then we brought the car to MSR Houston for on-track validation with Zach Beach, an ex-IndyCar driver who currently races GT3 and GT4 in IMSA.
The headline improvement is tunability. The Öhlins dampers give you real clicker adjustability, the kind of setup latitude GT3 and GT4 drivers use to dial in balance corner by corner. Combined with better body control and more consistent damping, the car rewards setup work in a way the stock shocks didn’t allow.
Full technical specifications and availability are coming. More detail in a dedicated post.
Lifeline Fire Suppression
Every new Rush SR ships with a Lifeline fire suppression system installed. Lifeline builds systems for Formula 1 and IndyCar. Their reusable cartridge design means if you pull the pin in an incident, you swap the cartridge rather than replace the whole unit.
For existing owners: if your current system is over two years old, it’s due for recertification. That’s a mail-in process with a small fee. An upgrade to the current Lifeline unit runs $1,245 plus installation. Call the shop: (713) 937-0000.
GCU: Coming Soon
We have a completely redesigned Gear Control Unit in development. Smaller, integrated, potted, and CANBUS-based. We will expose many more channels to the AiM dash, have a shift program that adapts to your car, remove the neutral shift button, and much much more. This upgrade is a long time coming and I can’t wait to stop diagnosing GCUs trackside. We will do a proper post on this when it is ready.
Where Things Stand
2025 was a hard year. New production infrastructure, losing our founder, changing management, keeping deliveries moving through all of it. The car came out better. Thank you to all of you who have stuck with us. Questions: (713) 937-0000 or info@rushautoworks.com.
