Stohr WF1 WF1 VS Rush SR SR

Stohr WF1 vs Rush SR: The Battle of Ultra-Lightweight Track Warriors

When it comes to all-out track performance, few genres are as focused as the sub-1000 lb, motorcycle-powered, prototype racers. The Stohr WF1 and the Rush SR are two of the most accessible yet outrageously fast entries in this rarefied class. Both promise to warp your sense of speed and cornering, yet they do so with distinct engineering philosophies, pricing, and on-track results. Let’s dig into the data, the driving experience, and the real-world implications for track enthusiasts.

Lap Time Showdown: Stohr's Unassailable Advantage

LapMeta’s extensive database leaves little doubt: the Stohr WF1 is in another league for outright pace. Across every track where both cars have posted laps, the Stohr takes the win, often by huge margins.

• Ozark International Raceway - CW: Stohr WF1 clocks a 2:14, a staggering 24 seconds faster than the Rush SR's best of 2:38.064 (both race-prepped).
• Sonoma Raceway - Long Pre 2024: Stohr's 1:30.49 bests the Rush SR by nearly 18 seconds (1:48.423, stock).
• Roebling Road Raceway - Road Course: Stohr again dominates, with a 59.17 to Rush's 1:15.54—a gap of over 16 seconds.
• Virginia International Raceway - VIR - Full Course: Stohr’s 1:49.43 is almost 16 seconds quicker than the Rush SR’s 2:05.1 (stock).
• Carolina Motorsports Park - Full: Stohr edges the Rush SR by just over 10 seconds (1:29 vs 1:39.25, both race-prepped).
• New Jersey Motorsports Park-NJMP - Thunderbolt: The gap narrows, but Stohr still leads by over 7 seconds (1:17.5 vs 1:24.75).
• Barber Motorsports Park - CW: Stohr’s 1:29.3 outpaces Rush’s 1:35.8 by 6.5 seconds.

These margins aren’t just decisive—they’re crushing. Even accounting for differences in driver talent, prep, and tire, the Stohr WF1’s performance envelope is in a different stratosphere.

Engineering, Purpose, and the On-Track Experience

The Stohr WF1 is a singular vision of what a sub-800-lb track weapon can be. With its ultra-light 780 lb curb weight, 243 PS motorcycle engine, and razor-sharp aerodynamics, the Stohr is a car that rewards the bold and the brave. The engine sits just behind the driver, and with rear-wheel drive and a featherweight chassis, it delivers a level of feedback and immediacy that’s almost alien, even among prototypes. This is not a car you drive so much as command—and it requires a deft touch to extract its full potential.

Contrast that with the Rush SR. At 924 lbs and 149 PS, it’s still a monster by any road car’s standard, but it’s designed for accessibility and reliability as much as outright speed. The Rush’s specification makes it a favorite among club racers and track-day drivers who want intense performance without the surgical edge (and expense) of the Stohr. The Rush’s focus on durability, cost control, and a broad operating window means it’s a car you can drive to your limit, not just the limit.

In short, the Stohr WF1 is for the apex predator—drivers who want to chase overall FTDs and lap records. The Rush SR is for the enthusiast who values seat time, fun, and a manageable learning curve, with enough pace to humble almost anything short of a prototype—but not another Stohr WF1.

Economics, Value, and the Big Picture

On price, the Stohr WF1 has always commanded a premium, both at initial purchase (with MSRP north of $80,000 for a new build, and used prices holding strong) and in running costs. Its specialized engineering, custom chassis, and limited production volume mean that every part is optimized for speed, not savings. For the driver who wants the ultimate time attack tool or a P1 shot in club racing, that’s money well spent.

The Rush SR, meanwhile, is a masterclass in value engineering. With a base price in the $35,000–$40,000 range, it brings prototype aesthetics and performance to a much broader audience. The car’s simplicity and parts commonality (including its use of a Yamaha motorcycle engine) translate to lower running costs and less garage time. In the used market, the Rush holds its value well, thanks to an expanding grassroots racing scene.

Neither car is built for the street, but both democratize the track experience in their own ways: Stohr for the lap record-obsessed, Rush for the “maximum fun per dollar” crowd.

Final Thoughts: The Choice is in the Mission

The data is unambiguous—the Stohr WF1 is the king of speed among these two, with lap time gaps often measured in dozens of seconds. It’s a car that pushes the limits of what’s possible in club-level prototype racing. But the Rush SR should not be overlooked. Its reliability, accessibility, and affordability make it a giant killer in its own right—just not when the Stohr is in the paddock.

If your goal is absolute pace and the thrill of chasing national-level records, the Stohr WF1 is the weapon of choice. If you want to maximize your track time, sharpen your skills, and enjoy prototype thrills without prototype bills, the Rush SR delivers an experience that’s nearly as visceral—and a lot more approachable.

In the end, both cars are proof that the most exciting racing machines aren’t always found in the mainstream—they’re built by passionate engineers for drivers who live for the perfect lap.
