Cadillac on this sleek prototype race vehicle showcased at The Quail during Monterey Car Week, and they’ll assert repeatedly that it’s merely a “design study,” a “concept,” a “race car initiative.” Inquire with individuals who are well-informed in paddocks worldwide, and they’ll inform you that the plans to market these streamlined Le Mans racers to clients are nearly complete.
That’s the most fitting description of this stunning creation that Cadillac dubs the V-One: an 830-horsepower, streamlined Le Mans Hypercar—capital H because the authentic model competes in WEC’s Hypercar division (and IMSA’s GTP). Regardless of whether General Motors intends to offer these to a broader market or a select few—or even just one individual like Porsche did for Roger Penske—the challenge of simplifying one of the globe’s most sophisticated race cars is significant.
There’s the engine aspect, the hybrid aspect, the electronics, suspension, downforce, and maintenance intervals that could quickly exhaust a very affluent individual, and, lastly, marketing a vehicle that 99.9% of individuals lack the skills to operate is an inherent challenge. For those who possess the skills, there’s the additional concern of where to drive it and how extensive a team of engineers is needed for its operation. Where do you store it, and how do you prepare it to ensure it starts again later?
I had a conversation with Sean O’Shea, the principal propulsion engineer for Cadillac Racing and GM Motorsport’s hybrid powertrains, to gather all of those insights and more. He and I had the opportunity to examine the V-One closely and discover what makes this project both ambitious and thrilling.
Here’s how Cadillac is crafting a Le Mans Hypercar that anyone can hop into and drive:
Jerry Perez: I understand the official company stance is that this is a concept, but what is Cadillac genuinely aiming to accomplish here? Is the intention just to create a concept that never materializes, or something that will actually happen? And what’s your role in all of this?
Sean O’Shea: As the engineering liaison connecting the design with the racing program, my goal is to ensure that [V-One] doesn’t drift too far from the race-car essence and that this could indeed become a reality. It’s a concept at present, but everything visible here is quite practical and could come to fruition.
I’m an avid racing enthusiast; I’ve been involved in racing since childhood, from go-karts to cars to dirt bikes, all of it. I am passionate about racing, so when I got engaged in this project, I aimed to develop a track car that was a simplified variant of our race car while still providing all the same tools and the same experience that a professional driver would encounter, but without excessive complexity.
Race cars are often characterized by their complexity, so how do you streamline a Le Mans racer?
Firstly, I want it to be an incredibly enjoyable track car, and a key feature is that it needed to be an “ambient start car,” correct? This means you can start it at 70 degrees and let it warm up autonomously without needing to pre-warm it [with auxiliary machinery like an F1 car]. Moreover, all the differential, traction control, and suspension are a simplified rendition of the real deal. This enables you to just get in and drive the car while having a fantastic time. However, I didn’t want to compromise on the sound, power, or downforce you’d find in a genuine race car. This ensures that when you enter it and look around, you experience the same view as any of our pro drivers such as Earl Bamber, Jack Aiken, or Delatraz. You will also find similar buttons around the cockpit but perhaps without all 12 control variations or so, right? That’s what I refer to as the simplified version: something us regular folks can learn, engage with, and enjoy.
I once chatted with Jenson Button while he raced the Acura ARX at the Rolex 24, and he explicitly stated that the steering wheel and several controls of the GTP car—as well as the rear axle, brake balance, and traction control—were more intricate than in an F1 car from his time. If he says that, I can hardly imagine what an average person would think.
We had Jenson drive the [WEC] car, and indeed, the race car project is so intricate given their objectives. Through settings, energy recovery, and energy per lap, I collaborated with our professional drivers and simply asked them: what elements would you like to simplify in the car to enhance enjoyment? They provided numerous suggestions, so if you observe the interior, it’s essentially an LMDH car, just a more straightforward version of it. We still have traction control with two settings—X and Y for lateral and longitudinal grip—and we genuinely wanted to include ABS in the car, although typically these cars lack it. I felt ABS would help mitigate issues surrounding break-in temperatures, tire heating procedures, and the like. Just let the ABS manage it, and allow the driver to focus on steering, shifting, and accelerating.
We collaborated closely with the [pro] drivers to understand how we could minimize complexity. On the propulsion side and differential side, we coordinated with all of our performance engineers to again find ways to simplify things. We visited Goodwood last year and this year, and the focus was on how can the car be user-friendly? You know, we began brainstorming calibration ideas to allow our driver to simply drive out of the paddock and onto the track without needing a team of engineers with them.
If you were to construct this, would the driver simply step in and go?
The intention would be that we hop in, start it, and drive off. Well, it’s essential to allow it to warm up before going anywhere, you know, give it a bit of care. This is expensive, after all.
Would customers keep their cars at home, or would Cadillac store and transport them to tracks, similar to how Ferrari does for its FXX program?
We have ideas and a sort of plan, but it’s not something we’re ready to reveal yet. But for me, as just an enthusiast, if I purchased this, I’d want to keep it at home to impress my neighbors.
Who has driven the V-One, and what feedback have they provided thus far?
Our professional drivers have taken it for a spin since it closely resembles the race car. We engineers haven’t really piloted it at all. I’ve been in the driver’s seat and nudged it around on electric drive, but nothing beyond that. I primarily lean on their expertise because they also drive our road cars; they have influenced the ZR1X programs and spend considerable time in the sim rig. Together, we thoroughly examined the interior [cabin] space and considered how to enlarge it a bit. I questioned whether we could eliminate the sway bars? They said, no, we need adjustable sway bars. I countered, okay, but do you solely require the rear and not the front? The drivers replied, you need both—so we kept both. That type of solution.
Which buttons did you retain on the dashboard and steering wheel, and what about air conditioning?
Yes, there is AC within the car. The race car becomes extremely warm, so we recognized the necessity of keeping that. There’s also a pit lane limiter and other buttons for adjusting various pre-discussed settings.
You retained the loud sound from the shift between electric and ICE, like the race vehicle when exiting the pit lane, right?
Indeed, we had no intention of changing any of that. Furthermore, these cars are quite uncomfortable at lower speeds, so it’s much simpler to maneuver the vehicle using electric power; thereafter, you can just drive around. The core idea is to make it easy to use. Start the vehicle, let it warm up. When you pull out of the pit lane, the ICE engine switches off, and you depart in EV. Then you release one of the paddles, activating the ICE engine, and you’re off.
What’s the most significant challenge of this project?
The interior, truly. It represents the most substantial alteration from the race vehicle. We want to ensure there’s adequate room for an average-sized person inside. Additionally, visibility is critical, as the race car tends to be quite constricted. We needed to accomplish all this without altering the tub shape, for if you modify the tub, you have to create new tooling and homologate everything else. After that, it was simply a matter of simplifying all the sensors and electronics.
Whenever an automotive company proclaims an “F1 car for the road,” it generally results in a rather chaotic outcome. Whether it’s the McLaren F1, the Mercedes-AMG One, you name it, they’re magnificent, yet they come laden with complexities, maintenance, and reliability headaches. I understand this isn’t an F1 car, but it’s pretty close.
I have never driven an AMG One but have gathered much information about it, including from forums. To me, however, the intricacy is simply unnecessary. The core experience lies in being in the car, savoring the joy, feeling the downforce, experiencing the G-forces, listening to the sound, and racing the vehicle on a circuit. Therefore, everything we did here was aimed at simplifying the race car, making it reliable and straightforward to use. The whole emphasis is to provide the owner with the experience of driving the car, not getting bogged down with gadgets, gizmos, screens, and everything else. Just drive the car!
What are maintenance intervals like for one of these?
Whenever we develop a performance vehicle, anything within GM begins with a vehicle technical specification. Thus, you specify what you want the car’s capabilities to be, right? Do you desire excellent fuel economy? Would you like faster 0-60 or lap times, and all of that? When drafting the vehicle technical spec for this, we targeted a lap time that was slightly slower than the race car and aimed our performance interval, which is the highest within GM, at 24 hours solely for tire changes. Hence, for 24 hours of racing, merely add fuel, change tires, and continue. If you aim to run for 24 hours, that’s what the vehicle will necessitate.
Finally, how will you assess if a potential customer can handle a V-One? Can an individual without race car experience simply jump in and enjoy?
That’s my hope, and it pertains to me as well. I’ve piloted many vehicles throughout my life, but I’ve never maneuvered a full downforce car, so my ultimate aspiration is just to drive this and have a wonderful time.
