The X1
The world's lightest full ground-effects race car.

"Nimble, fast and mega responsive — and super predictable. The bang for buck is incredible."
Straight out of the car after his first laps in the X1. His words, not ours.
410kg, pinned to the road by full ground-effect tunnels. The harder you lean on it, the more grip there is.
Every safety element on the X1 is the result of looking at how racing cars hurt people and designing it out. Not because regulations demanded it — because it was the right thing to build.
The X1's floor is shaped as a pair of three-metre Venturi tunnels. As air enters and the cross-section narrows, it accelerates. As velocity increases, static pressure drops. The low-pressure zone created beneath the entire floor means atmospheric pressure above is literally pushing the car into the ground — not at two points like a wing, but across the full length of the chassis simultaneously.
This matters because it keeps the centre of pressure stable as speed rises. The car doesn't shift balance as grip builds — it just gets more planted, more predictable, and more capable. The faster you go, the harder it works.
At low speed the X1 feels accessible. At high speed the tunnels are at full capacity and the car is pinned to the circuit with a force that has to be experienced to be understood. The grip limit isn't a wall you hit — it's a horizon that keeps moving away from you.
That's what three metres of ground effect buys you. At this price point, nothing else offers it.
XE650 infusion woven glass is a significant step above standard wet-laminated fibreglass mat — lighter, stronger, and more consistent. The standard body on the X1 is not a compromise.
The full carbon body hones the aero surfaces and saves meaningful weight over the already-light woven glass option. For serious racing where every kilogram is a lap time, this is the spec to choose.
