For years, the Devel Sixteen was treated like automotive vaporware a mythical creature born in Dubai that made internet headlines with promises of absurd, physics-defying numbers. But when you strip away the flashy motor show smoke and mirrors, you find a terrifyingly real, unhinged piece of mechanical engineering hiding underneath.
The goal wasn’t to build a refined, corner-carving track weapon. The goal was to engineer a land-bound rocket capable of hitting 300+ mph through pure, unadulterated internal combustion. To do that, the creators had to throw out conventional supercar design and look to the world of extreme drag racing.
Here is the technical breakdown of the heart and soul of the Devel Sixteen.
The Heart: The 12.3-Liter Quad-Turbo V16
The crown jewel of the Devel Sixteen is its engine, custom-built by Steve Morris Engines (SME) in Michigan, USA. SME is legendary in the hardcore drag racing scene, and they treated the Devel project like a mad science experiment.
This isn’t two V8s welded together. It is a completely bespoke, ground-up 12.3-liter V16 engine.

The Block and Internals
- Billet Aluminum Monoblock: The entire engine block is machined from a massive, single block of billet aluminum. Cast iron or standard aluminum alloys would simply crack under the combustion pressures this unit generates.
- The Valve Train: It utilizes a high-strength camshaft setup with 32 titanium valves.
- Crankshaft Tech: A custom-engineered, single-piece billet steel crankshaft sits at the bottom, balanced meticulously to handle thousands of rotations per minute under immense load.
The Induction System
To feed 12.3 liters of displacement, the engine relies on four massive 81mm quad-turbos. The plumbing required to route the exhaust gasses to spool four distinct turbos while keeping intake temperatures manageable is an packaging nightmare. When fully spooled, the system forces massive amounts of compressed air into the intake, generating an engine dyno-proven 5,007 horsepower and 3,757 lb-ft of torque on race fuel.
The Three Tiers of Power
Recognizing that a 5,000-hp track-only monster is practically undrivable on public roads, the powertrain configuration was split into three distinct tiers:
Parameter | Tier 1: The Entry Model | Tier 2: The Street King | Tier 3: The Full Spec (Track Only) |
|---|---|---|---|
Engine Configuration | Custom V8 | 12.3L V16 | 12.3L V16 (Race Spec) |
Induction | Twin-Turbo | Quad-Turbo | Quad-Turbo (High Boost) |
Fuel Type | Pump Gas (98 Octane) | Pump Gas (98 Octane) | Race Fuel (C16) |
Horsepower Output | ~1,500 HP | ~3,000 HP | 5,007 HP |
Torque Output | ~1,000 lb-ft | ~1,770 lb-ft | 3,757 lb-ft |
The Powertrain Bottleneck: Getting Torque to the Asphalt
Building a 5,000-hp engine on a stationary dyno is one thing. Bolting it into a carbon-fiber chassis and expecting a gearbox not to explode into metal confetti the moment you touch the throttle is another. This is where the Devel Sixteen faces its greatest engineering hurdle.
The Transmission Dilemma
Standard dual-clutch transmissions (DCTs) used by Bugatti or Koenigsegg are engineered to max out around 1,500 to 2,000 hp. Hook them up to 3,700 lb-ft of torque, and the clutches will instantly slip or shear their teeth off.
- The Street Version Gearbox: For the 3,000-hp street version, Devel utilizes a heavily modified, dual-clutch transaxle system. The electronic control unit (ECU) has to actively restrict torque in the lower gears, creating a progressive power curve so the tires can actually hook up without instantly vaporizing.
- The 5,000-HP Track Version Gearbox: To handle the full race spec, the dual-clutch setup is tossed aside in favor of a custom-built, high-impact top-fuel drag racing transmission. These gearboxes use multi-disc clutches made of specialized composite materials designed to handle sudden, violent transfers of energy.
Power Delivery & Traction Control
The car is strictly rear-wheel drive (RWD). Transferring that much power through just two contact patches requires incredibly sophisticated power management software.
The powertrain relies on variable boost control. At launching speeds, the turbos operate at a fraction of their capacity. As the vehicle gains momentum and aerodynamic downforce presses the rear tires into the tarmac, the wastegates close, ramping up the boost incrementally. You only get the full 5,007 horsepower when the car is already moving at triple-digit speeds.
The Verdict: Raw Mechanical Overkill
The Devel Sixteen’s powertrain breaks away from modern hypercar trends. There are no hybrid electric motors, no torque-vectoring front axles, and no eco-modes. It is a brutal throwback to old-school hot-rodding, scaled up to an aerospace level of excess. By combining a single-frame billet V16 block with quad-turbo force multiplication, it pushes the absolute thermal and structural limits of what an internal combustion engine can achieve.
