California-based boutique automaker Oilstainlab has revealed the near-production version of its daring HF‑11 supercar, presented in a striking Negroni Orange finish. Created by twin brothers Nikita and Iliya Bridan, the HF‑11 is designed to be shorter and wider than a Ferrari 296 GTB. It promises extreme performance in a lightweight body, with electric versions targeting under 953 kg and combustion variants aiming for just 900 kg.
Flat-Six Powerhouse With 12,000 RPM Redline

At the heart of the HF‑11 lies a mid-mounted flat-six engine steeped in motorsport heritage. Two petrol engine options will be available: a 4.6‑litre version producing 600 bhp, and a fire-breathing 5.0‑litre engine delivering an astonishing 1,200 bhp with a sky-high 12,000 rpm redline. Power is sent to the rear wheels only, via a six-speed manual or a seven-speed sequential gearbox, both paired with a limited-slip differential.
Electric Powertrain Alternative With Battery Swap Potential
In parallel with the internal combustion model, Oilstainlab has developed an 800 bhp electric version using an 80 kWh battery. The HF‑11 can be configured to swap between combustion and electric setups, thanks to a clever “Thunder‑Volt” powertrain-swap system or rear subframe exchange, allowing owners unmatched flexibility in a single chassis.
Advanced Lightweight Engineering and Motorsport Underpinnings

Built around a carbon-fibre monocoque tub and aluminum subframes, the HF‑11 features pushrod suspension and Ohlins dampers. Braking is handled by six-piston calipers up front and four-piston units at the rear, clamping on massive 394 mm and 390 mm rotors. Aerodynamics are race-grade, with the car expected to generate 589 kg of downforce at 150 mph.
Aggressive, Track-Inspired Styling

The HF‑11’s appearance is raw and functional, revealing its rear-mounted powerplant beneath aggressive bodywork. Splitters, diffusers, and motorsport cues abound. Access to the cabin is through Le Mans-style upward-swinging doors, and the minimalist interior blends carbon fibre with customizable digital and analog instrumentation.
Built for Drivers Without Compromise

Despite its extreme performance, the HF‑11 is designed with the driver in mind. It accommodates helmeted drivers up to 6’3”, includes features like air conditioning, and offers a reversing camera for street usability. Yet the focus remains pure performance and analog feedback.
Exclusive Production With Race-Bred Craftsmanship
Only 25 HF‑11 units will be built, with production managed in collaboration with Crawford Composites, specialists known for building carbon structures for Le Mans and IndyCar racers. Each car will start at US$1.85 million, while dual-powertrain models will command closer to US$2.3 million.
Performance That Rivals Modern Hypercars
With a target 0–60 mph time around three seconds and race-car weight, the HF‑11 is set to challenge even the most powerful modern hypercars, but with a visceral, driver-focused twist. This car is not just about numbers—it’s about the experience.
Early Buyers to Influence Final Development
Buyers of the first batch—referred to by Oilstainlab as “maniacs”—will be invited to join a collaborative development journey. Their input will help shape final specifications ahead of production beginning in 2026.
Bridging Analog Thrill and Electric Potential
The HF‑11 is a rare machine that spans both ends of the performance spectrum: offering an unfiltered, analog flat-six driving thrill or instant electric power. For those looking to escape conformity, Oilstainlab’s HF‑11 may just be the antidote to the sanitized supercar.
Summary (100 words)
The HF‑11 is a radically engineered, ultra-lightweight supercar from California’s Oilstainlab, featuring a 5.0-litre flat-six engine with up to 1,200 bhp and a 12,000 rpm redline, or an 800 bhp electric variant. Designed for ultimate driving purity, it offers a sub-1,000 kg chassis, rear-wheel drive, manual or sequential gearboxes, and aerodynamic hardware to deliver up to 589 kg of downforce. Limited to 25 units and priced from $1.85 million, the HF‑11 is customizable, track-focused, and built with motorsport-grade components. Its unique ability to switch between electric and combustion setups positions it as a rebellious, dual-identity supercar for enthusiasts seeking performance with soul.
