Oilstainlab HF-11 Supercar: The $1.85M Hand-Built Hypercar That Roars to 12,000 RPM

Oilstainlab HF-11 Supercar: In a world increasingly driven by automation, electrification, and digital assistance, one boutique automaker is flipping the script—introducing an analog monster that unapologetically celebrates raw performance and old-school engineering. Meet the Oilstainlab HF-11, a low-volume, ultra-lightweight supercar that redefines what it means to drive.

The HF-11, which has a starting price of $1.85 million and just 25 cars planned worldwide, is more than simply another supercar—it’s a statement. Featuring both a screaming flat-six gasoline engine with a 12,000 rpm redline and an electric variant with a simulated manual gearbox, this car bridges tradition and innovation. It’s for those who crave connection—not just horsepower.

Oilstainlab: From Concept Art to Engineering Reality

Oilstainlab may not be a household name like Ferrari or McLaren, but the company has quickly built a reputation among automotive purists. What started as a visionary design project evolved into a hands-on effort to produce one of the most distinctive hand-built performance machines in the world.

The HF-11 is the result of 3,500+ hours of development, sculpted from a carbon-fiber monocoque chassis designed entirely in-house. The design aesthetic is a nod to the golden era of motorsport, with dramatic curves and race-ready aero that recalls Can-Am cars and early Porsche endurance racers. But beneath its nostalgic surface lies cutting-edge technology.

Engine Options: Flat-Six Fury or EV Revoltion

The two very different powertrains available for the HF-11 are each designed for a distinct type of enthusiast.

The first is a naturally aspirated flat-six coupled to either a sequential or manual gearbox with six speeds. With an ear-splitting 12,000 rpm redline and a target output of 650 horsepower, it promises visceral excitement and a mechanical purity rare in today’s hypercar world. An even more powerful 5.0-liter 1,200-hp variant is reportedly under development.

For those leaning toward the future, the HF-11 also comes in an electric version, delivering approximately 800 hp. While most EVs are lauded for silence and efficiency, this one bucks the trend. It features manual-shifting capability—a simulated gearbox that mimics the feel and control of traditional driving. That’s virtually unheard of in electric hypercars.

Design and Aerodynamics: Retro Looks, Modern Efficiency

Visually, the HF-11 is a work of art. It combines contemporary design principles with race vehicle influence from the mid-20th century. From the sculpted fenders and butterfly doors to the exposed engine bay and carbon-fiber underbody, the HF-11 is unmistakably crafted for drama—both standing still and at full speed.

Downforce figures are just as impressive as the aesthetics. The car generates up to 1,300 pounds of aerodynamic grip at 150 mph, thanks to a carefully balanced body, venturi tunnels, and airflow management around the cockpit and rear end. Every curve serves a functional purpose, blending wind tunnel efficiency with visual nostalgia.

Interior: Analog Instrumentation in a Digital Age

Step inside, and you’ll find no massive touchscreens or virtual dashboards. Instead, the HF-11’s interior is delightfully analog. It features five circular gauges suspended in a minimalist layout, reminiscent of race cars from the ’60s and ’70s. A traditional gated manual shifter—complete with satisfying metal clicks—sits front and center in the gasoline variant.

Despite its race-focused design, the interior is spacious enough to accommodate drivers over 6’3″ tall wearing helmets, ensuring usability for real-world driving and track days. High-end materials like Alcantara, leather, and carbon-fiber trim ensure that the car feels as luxurious as it is mechanical.

Lightweight Engineering: Speed Without Mass

Performance isn’t just about horsepower—it’s about power-to-weight ratio. The HF-11 weighs just 2,000 pounds (907 kg) in gasoline form and about 2,100 pounds (953 kg) in its electric configuration. That’s significantly lighter than most modern supercars and hypercars, many of which push past 3,500 pounds due to added electronics and luxury gear.

The lightweight construction is achieved through the extensive use of aerospace-grade carbon-fiber, billet aluminum suspension components, and minimalist design ethos. Even the electronic power steering and regenerative braking systems in the EV version have been optimized to save weight.

Driving Dynamics and Track Potential

While the official 0-60 mph time hasn’t been published, estimates suggest a launch time around 3.2 seconds—respectable, but not the main goal. The HF-11 isn’t designed to win stoplight drag races; it’s designed to conquer corners, communicate feedback, and reward skilled driving.

A fully independent double wishbone suspension developed in partnership with Ohlins, along with giant carbon-ceramic brakes, ensures that the HF-11 stays planted even at triple-digit speeds. Track day enthusiasts will appreciate the responsive steering, predictable chassis behavior, and neutral balance enabled by its mid-engine layout.

Customization and Ownership Experience

Each HF-11 will be hand-built to customer specification. Owners can work directly with the Oilstainlab team to select color combinations, materials, finishes, and optional performance packages. An optional “Maniac Pack” includes a higher-revving engine, enhanced suspension tuning, and track telemetry.

Oilstainlab has also hinted at a dedicated owners’ club, providing track day access, concierge services, and future upgrades. Given the limited production of just 25 vehicles, the brand is cultivating an ultra-exclusive ownership experience akin to owning a one-off race car.

A Future-Classic in the Making

The HF-11 may be a boutique project, but it’s already being heralded as one of the most interesting and emotionally resonant supercars of the decade. By offering a manual gearbox, analog controls, and low curb weight, Oilstainlab is targeting a rare niche: the enthusiast who values connection over computers, emotion over automation.

With both electric and gasoline options, the HF-11 appeals to traditionalists and forward-thinkers alike. It proves that the future of supercars doesn’t have to be sterile or silent—and that even in 2025, the driver can still sit at the center of the experience.
