A Spanish company is developing an innovative engine that combines combustion and electricity features, promising to transform the automotive sector.
The motto of the Spanish company IN Engine, "The future is eclectic”, which may reflect the philosophy that drove the development of the engine e-Rex, an innovative solution that combines traditional combustion concepts and modern demands for electrification.
Despite being technically classified as a two-stroke, the engine represents a proposal that promises to transform the automotive market.
The e-Rex design combines the advantages of traditional two-stroke engines – greater power in relation to size and thermodynamic efficiency – with innovations that eliminate their disadvantages.

By separating the combustion, lubrication and cooling processes, it eliminates the need to mix oil and fuel, a problem that contributed to these engines' bad reputation as polluting and noisy.
This solution positions it as an efficient range extender for electric vehicles, responding to current sustainability and performance challenges.
Closer to scale production
The prototypes of the e-Rex are rapidly moving towards the industrial development phase. Based in Granada, INNengine plans applications in a variety of sectors, from the automotive industry to the aeronautical sector, including drones and small aircraft.
This broad approach demonstrates the engine’s transformative potential for different markets.
In a conventional engine, the intake, compression, combustion and exhaust phases occur independently. However, in two-stroke engines, intake and exhaust occur simultaneously.
O e-Rex optimizes this principle with an innovative architecture that uses four opposed pistons, organized in pairs that share a combustion chamber. This design allows for smoother operation, less noise and vibration, and a compact size.
Variable compression and improved efficiency
One of the biggest differences of the e-Rex is its variable compression system. This feature is achieved by moving end plates that control the clearance between the pistons during compression, allowing greater control and efficiency in engine performance.
This expands its use in applications ranging from automobiles to power generation.
The most notable prototype so far is a Mazda MX-5 Miata equipped with the e-Rex engine. This 500cc engine delivers 126 horsepower, comparable to the original 1,8-liter engine in the model, but in only half the space and with significantly reduced weight.
This compact configuration also allows the vehicle to be equipped with all-wheel drive, further expanding its possibilities.
Solution to electrification challenges
In the transition to electric mobility, the e-Rex emerges as a flexible and efficient range extender. It is capable of operating with synthetic fuels, reducing dependence on large and expensive batteries – one of the biggest challenges for current electric vehicles.
This solution not only reduces production costs, but also increases the safety of cars by reducing their weight.
Lighter vehicles also have a positive impact on autonomy and performance. By dedicating the combustion engine to long journeys, the system allows daily commutes to be lighter and more efficient.
Studies also show that lighter vehicles tend to cause less serious damage in accidents, a relevant point in road safety.
Impact on various sectors
The e-Rex is not limited to the automotive industry. According to INNengine, the engine has potential for applications such as power generation in marine environments and off-grid installations, where efficient and compact solutions are highly valued.
Although there are still challenges for its large-scale adoption, the e-Rex already stands out as one of the most promising innovations in the field of hybrid engines.
With its multifunctional approach and bold design, the e-Rex engine positions INNengine as a pioneer in transforming the energy and mobility market.
The combination of advanced technology, fuel flexibility and greater efficiency promises to change the course of the industry in the coming years. We can only wait for the next steps and the impacts of this revolution on global markets.
If you explained the concept of simultaneous combustion and induction, you would give a better grade.
The future is here, it even applies to motorcycles, congratulations
