• 🇺🇸 A Minnesota-based company, Runge Cars, is redefining American craftsmanship with the Runge R3 Supercar, featuring a bespoke 5.3L air-cooled flat-eight engine.
  
• Designed for pure driving emotion — lightweight, hand-built, and fully analog — it delivers a rare 9,000 rpm experience.
  
• Estimated output: around 600 horsepower, nearly 100 hp more than Porsche’s 4.0L flat-six.
  
• Built in collaboration with Swindon Powertrain and air-cooled specialist Sol Snyderman.
  
• Production will be ultra-limited, ensuring exclusivity and collector appeal.

A Tiny American Builder Making a Giant Statement

In a world where supercars are dominated by massive automakers and complex hybrid systems, a small Minnesota brand is turning heads with something refreshingly pure. Meet the Runge R3 Supercar, a hand-crafted, analog performance machine that dares to challenge European royalty — not with electronics, but with sheer mechanical artistry.

Runge Cars isn’t a household name yet, but among enthusiasts who value craftsmanship over corporate mass production, it’s quickly becoming one to watch. Known for its coachbuilt creations over the past decade and a half, the company has now raised the bar with the R3, a car that doesn’t just look vintage — it embodies the soul of driving from an era before touchscreens and drive modes ruled the road.

The Pursuit of Analog Perfection

Runge’s vision for the R3 is refreshingly clear: to “deliver the most visceral, analog driving experience available today.” In an era of digital dashboards and one-pedal driving, that’s not just marketing talk — it’s a bold promise.

At the heart of the Runge R3 Supercar lies an engineering marvel — a 5.3-liter naturally aspirated, air-cooled flat-eight engine known as the Hetzer. This powerplant is unlike anything currently built in the United States. It’s the result of a collaboration between Runge, British engineering firm Swindon Powertrain, and air-cooled expert Sol Snyderman.

A Flat-Eight That Revs Like a Race Engine

The Hetzer is an enthusiast’s dream: four valves per cylinder, dual overhead camshafts, and a 12:1 compression ratio. It’s tuned to spin up to 9,000 rpm, and as Runge proudly notes, it “revs with the urgency of a race engine.”

While official numbers haven’t been released, early estimates suggest around 600 horsepower, nearly 100 hp more than Porsche’s most powerful naturally aspirated 4.0-liter flat-six. That’s serious output for a car this light — and it hints at staggering performance when paired with the R3’s manual transmission and rear-wheel drive setup.

Perhaps the most impressive part? The flat-eight is reportedly compact enough to fit into classic air-cooled Porsche 911 platforms — a potential game-changer for future custom builds.

Transmission, Weight, and Pure Driving Feel

Every Runge R3 Supercar comes equipped with a six-speed manual gearbox, sending power exclusively to the rear wheels. There are no dual-clutch transmissions, no drive mode selectors — just driver, car, and an open road.

Weighing in at a featherlight 780 kilograms (1,719 pounds), the R3 is set to deliver a power-to-weight ratio that rivals million-dollar exotics. Combine that with a perfectly balanced mid-engine layout, and it’s easy to imagine the R3 carving through mountain switchbacks or dominating a track day with surgical precision.

A Design That Blends Art and Speed

Runge’s design philosophy blends classic endurance racer aesthetics with modern aerodynamic efficiency. From the renderings, the R3 features:

• A low-slung nose and round headlights reminiscent of 1960s Le Mans icons.
  
• A compact cockpit designed for pure connection between driver and machine.
  
• High-mounted wing mirrors on the A-pillars for a vintage racing look.
  
• A curved rear wing that enhances both stability and style.
  

Every curve, vent, and panel is hand-formed — not stamped out of steel by robots — giving the R3 an old-world craftsmanship that’s all but extinct in today’s automotive landscape.

Crafted, Not Manufactured

Unlike mass-market supercars, each R3 will be hand-built to order, ensuring no two are exactly alike. Runge’s team focuses on artistry, from metal shaping to final assembly. This approach doesn’t just create a car — it creates a legacy.

Given the level of manual craftsmanship involved, production numbers will be extremely limited. Don’t expect to see these in dealer showrooms or big city car meets — the Runge R3 Supercar is destined for discerning collectors who appreciate mechanical purity over digital excess.

No Price Yet, But Expect Rarity

Runge hasn’t revealed pricing for the R3 or its flat-eight engine yet, but one thing’s certain: exclusivity comes at a cost. Considering the R3’s engineering and bespoke nature, experts expect it to command a premium similar to low-volume performance icons like Singer’s reimagined 911s or Pagani’s early Zondas.

And honestly, that feels right. Cars like this aren’t about affordability — they’re about preserving the emotion of driving before it’s lost to electrification and automation.

Why the Runge R3 Supercar Matters

The Runge R3 Supercar isn’t chasing lap records or mass production. It’s about preserving the soul of driving — something even major brands like Ferrari and Porsche are slowly moving away from.

In a market obsessed with efficiency, touchscreens, and driver aids, Runge is boldly betting that there’s still room for passion-driven engineering. The R3 reminds us that cars can be art — not just transportation.

Final Thoughts: An American Dream in Metal

As someone who’s watched the supercar scene evolve over the years, I find Runge’s approach deeply refreshing. The R3 isn’t just another sports car — it’s a statement that craftsmanship and connection still matter.

If you’ve ever missed the raw feel of mechanical feedback, the hum of an air-cooled engine, or the satisfaction of shifting your own gears, the Runge R3 Supercar might just restore your faith in what driving used to mean — and could still be.
