Design & Looks
At first glance the e‑Rex looks like a stack of futuristic Lego bricks. It packs four spark plugs and eight pistons into a cylinder block that’s barely larger than a lunchbox. The real trick is its variable‑compression system. A tiny actuator shifts the piston travel in less than a second, letting the engine run lean for highway cruising or high‑compression for city acceleration.
Because the engine is so compact, it can be mounted transversely or even vertically in tight‑fit platforms. The metal housing is brushed aluminum, which keeps weight down and gives the unit a clean, high‑tech look.
Performance & Mileage
Performance numbers are still being tested, but early reports suggest a modest 30‑35 mpg combined rating – impressive for a gasoline engine of this size. The variable compression means the engine can stay at its most efficient point for most driving conditions, cutting fuel use without sacrificing power when you need it.
Drivers who have tried a demo say the power feels surprisingly smooth. The four‑spark‑plug arrangement fires each cylinder twice per cycle, reducing vibration and delivering a steadier torque curve.
Price & Rivals
Pricing hasn’t been nailed down yet, but the prototype is rumored to cost around $2,500, far below the $4,000‑$6,000 range of comparable small‑displacement engines. If the final price stays low, the e‑Rex could challenge the likes of the Suzuki Celerio’s 1.0‑L engine or the new Ford EcoBoost‑lite units.
- Lower upfront cost
- Better fuel economy than traditional 1.0‑L engines
- Compact size opens new vehicle design options

FAQ
- What is the mileage of the INNengine e‑Rex? Early tests show about 30‑35 mpg combined, thanks to its variable‑compression system.
- Is the e‑Rex worth buying for a small city car? If you value low purchase cost and better fuel economy, the e‑Rex offers a compelling alternative to traditional 1.0‑L engines.
- Can the e‑Rex be used in hybrid setups? Its compact size makes it a good candidate for plug‑in hybrids, but the current version is a pure gasoline unit.
