the breakdown The Dallara Monoposto Stradale is a street-legal, single-seat car built in Italy. It has 395 horsepower, extreme aero, and a race-style design focused on driving. It's being auctioned by RM Sotheby's for €700K+, with proceeds to charity. Did you know that in Italy in 2020, a car was built with a single, centrally located seating position—and it was type-approved for legal road use? Well, now you do. Frankly, we had no idea this existed either, but after seeing photos of this unusual one-seat Dallara, we had to learn more. It doesn’t look like an early April Fools’ joke, and it’s being auctioned by RM Sotheby's with an estimate of more than $809,000 (€700,000 at today's exchange rate). A Jaw-Dropping Single-Seater Dallara Monoposto Stradale The lot, set to cross the block in Monaco on April 25, has an unusual backstory. According to Dallara, the project was created during the 2020 lockdown. While many of us were busy baking bread, Giampaolo Dallara, with help from a group of young engineers and the design team, decided to bring a new road-going single-seater to life. This isn’t a re-bodied Dallara Stradale either, but a dedicated project that resulted in a one-off model called Macchina Posto Singolo. The first thing that stands out is the single central seat, protected by an extremely low, minimalist windshield, literally surrounded by the carbon-fiber structure. The nose is different from the Stradale as well, with large lower air ducts, a sharper shape, and completely new headlights. Equally obvious is the aerodynamic attention at the rear. The single-seater wears a lower, longer tail with a small upper wing and large lower vents that work with a massive three-step diffuser ramp. Just Enough Room For A Wheel & Seat Inside the tight cockpit, which is highly technical and focused purely on driving enjoyment, there’s no manual gear lever—there would be almost no room to operate it. The missing clutch pedal and the paddle shifters confirm this car uses an automatic transmission, the same six-speed dual-clutch unit as the Dallara Stradale rated at 395 horsepower. The steering wheel and digital instrument cluster are unchanged from the base model, with the main controls and turn-signal indicators neatly grouped on the carbon-fiber panel. To the right of the seat is the mechanical parking brake lever—an essential hallmark carried over from the original model. If the exterior and interior change, there are updates under the skin too. The chassis of the roadgoing single-seater (with a strictly lowercase “s,” so it won’t be confused with the Stradale) differs from the two-seater’s, while the engine remains the Ford-sourced 2.3-liter turbocharged gasoline four-cylinder, in 395-hp form and homologated to Euro 6e. Photo by: RM Sotheby's If this Macchina Posto Singolo—an exceptionally rare automobile—appeals to you, you can place a bid on April 25. The auction estimate is more than €700,000, and the lot is offered with no reserve, meaning the highest bidder will win it regardless of the final number. Proceeds will go to the Fondazione Caterina Dallara, dedicated to the founder’s daughter, who passed away in 2007. This story originally appeared on Motor1 Italy Motor1's Take: The Dallara Monoposto Stradale is one of those rare cars that feels genuinely special—and it looks incredible.
