Marco pressed his foot to the floor, and the little Caterham-style kit car beneath him came alive. The 5 cylinder engine screamed past 12,000 rpm, then 14,000, the sound bouncing off the Dolomites like a chainsaw cutting through silk. His passenger – a journalist who’d driven everything from hypercars to Formula One – gripped the roll cage and shouted over the noise: “This thing’s insane!”
When they pulled into the pits, both men were grinning like teenagers who’d just discovered their dad’s motorcycle keys. The engine ticked and pinged as it cooled, filling the air with that unmistakable smell of hot metal and racing fuel.
“You know,” Marco said, patting the tiny engine bay, “they keep telling us petrol is dead. But listen to that.” Even at idle, the 5 cylinder engine had a heartbeat you could feel through your chest.
Europe’s Last Stand Against Electric Everything
While the rest of the automotive world rushes toward electric powertrains, a small group of European engineers is making one final, defiant statement. They’ve built something that shouldn’t exist in 2025: a 1.0-liter, 5 cylinder engine that produces 240 horsepower and revs to 16,000 rpm.

This isn’t just another engine development story. It’s a last-ditch effort to keep the soul of internal combustion alive in a continent that’s rapidly banning everything with a tailpipe.
The numbers sound impossible. Most modern engines struggle to make 100 horsepower per liter reliably. This 5 cylinder engine delivers 240 hp from just 1000cc – that’s Formula One territory, but built for track days and weekend warriors.
“We knew this might be our last chance,” explains one of the lead engineers, who asked not to be named. “In five years, regulations will make this type of development nearly impossible. We had to do it now.”
The Engineering Marvel Behind Those Crazy Numbers
Building a 5 cylinder engine that survives 16,000 rpm requires throwing conventional wisdom out the window. Every component is designed like it belongs on a MotoGP bike, not in a road car.
Here’s what makes this engine possible:
- Ultra-light pistons – Forged from aerospace-grade aluminum
- Titanium valves – Lighter than steel, capable of the extreme valve speeds
- Dry-sump lubrication – Keeps oil flowing even under extreme cornering forces
- Motorcycle-style internals – Components sized for maximum rpm capability
- Racing ECU – Controls ignition timing with millisecond precision
- Oversquare bore dimensions – Shorter stroke allows higher revs
| Specification | Value |
|---|---|
| Displacement | 1.0 liter |
| Configuration | 5 cylinder inline |
| Power Output | 240 hp |
| Maximum RPM | 16,000 |
| Weight | 85 kg |
| Power-to-Weight | 2.8 hp/kg |
The development took three years of constant refinement. Early prototypes barely lasted 100 hours before major components failed. The current version has proven itself through thousands of track kilometers.
“We went through seventeen different piston designs,” recalls the chief technician. “Each failure taught us something new about what aluminum can and can’t handle at these speeds.”
Who Actually Buys These Mechanical Masterpieces?
You won’t find this 5 cylinder engine in any showroom. It’s built for a very specific customer: people who build their own track cars and don’t care about fuel economy, emissions, or practicality.
The typical buyer owns a Caterham, Lotus Seven replica, or custom hillclimb special. They want something that sounds like a motorcycle and accelerates like a small fighter jet.
Current customers include:
- Track day enthusiasts – Weekend warriors with serious budget
- Hillclimb competitors – Racing drivers who need maximum power-to-weight
- Kit car builders – People assembling their own lightweight specials
- Racing teams – Formula student and amateur racing categories
One customer, a retired engineer from Switzerland, has put over 15,000 kilometers on his engine across two racing seasons. “I know it’s not practical,” he admits. “But every time I hit 14,000 rpm, I remember why I love cars.”
The price reflects the specialized nature: each 5 cylinder engine costs more than many complete cars. But for buyers in this niche, the experience is worth every euro.
The Race Against Regulatory Time
This 5 cylinder engine represents more than impressive engineering – it’s a race against time. European emissions regulations are tightening every year, making projects like this increasingly difficult to certify.
While the engine meets current track-only regulations, future rules could make even limited production impossible. The manufacturer is rushing to build as many units as possible before regulatory doors close completely.
“We’re basically creating automotive archaeology,” explains one industry insider. “Future generations will look at engines like this the way we look at steam locomotives – impressive, beautiful, but completely extinct.”
The irony isn’t lost on anyone involved. At a time when mainstream manufacturers struggle to make 300-horsepower engines exciting, a tiny specialist has created something that makes professional race car drivers giggle like children.
Orders are already booked solid through 2026, with a waiting list that reads like a who’s who of European track day culture. Each engine takes weeks to hand-assemble, tested individually on the dyno before shipping.
“Every engine gets the full treatment,” the lead engineer explains. “We know each one might outlive the entire internal combustion era. They have to be perfect.”
FAQs
How reliable is a 16,000 rpm 5 cylinder engine?
With proper maintenance and high-quality fuel, these engines have proven surprisingly durable for track use, with some logging over 15,000 kilometers without major issues.
Can you put this engine in a regular road car?
Technically possible but not practical – it’s designed for lightweight track cars and requires racing fuel, frequent maintenance, and isn’t emissions certified for road use.
Why 5 cylinders instead of 4 or 6?
The 5 cylinder configuration provides unique sound characteristics and optimal balance for this displacement and power target, creating the distinctive howl enthusiasts love.
How much does one of these engines cost?
Pricing starts around €35,000 for a basic specification, with fully-built race versions exceeding €50,000 depending on options and accessories.
Will they keep making these engines after 2026?
The manufacturer plans to continue as long as regulations allow, but admits future European emissions rules may eventually make production impossible.
What kind of fuel economy does it get?
Fuel economy isn’t really the point – expect single-digit liters per 100km during spirited driving, worse on track, but that’s not why people buy these engines.
