Compact Rotary Engine That Doubles Electric Vehicle Range Without Adding Bulk

transportPilotedTRL 7

Imagine your electric car could carry a tiny backup engine — smaller than a suitcase — that kicks in when the battery runs low and takes you the rest of the way home. That's what CREEV built: a compact rotary engine (think Wankel, but improved) that sits inside an EV and charges the battery on the go. The trick is it's far smaller and lighter than existing range extenders, so it actually fits in small cars and vans where space is tight. They've patented fixes for the old reliability and efficiency problems that held rotary engines back.

The business problem

What needed solving

Electric vehicles still suffer from range anxiety — while 44% of drivers care about emissions, only 5% would consider buying an EV because they worry about running out of charge. Existing range extender engines are too bulky and heavy for small commercial and domestic vehicles where cabin and cargo space matters most. Automotive manufacturers need a compact, efficient backup power source that doesn't compromise vehicle design.

The solution

What was built

The project delivered a fully integrated CREEV unit within a mounting frame and completed the physical integration of the engine system and generator. These are working hardware demonstrators of a patent-protected compact rotary range extender engine ready for OEM evaluation.

Business applications

Who can put this to work

Automotive OEM — Electric Vehicles

enterprise

Target: Electric vehicle manufacturers producing small city cars or compact commercial vehicles

If you are an EV manufacturer struggling to offer competitive range in compact vehicles — this project developed a fully integrated, patent-protected rotary range extender engine that delivers high power density in a fraction of the space conventional extenders require. With only 5% of drivers willing to buy an EV due to range concerns, this technology directly addresses the barrier holding back your sales.

Automotive Tier 1 Powertrain Suppliers

enterprise

Target: Tier 1 suppliers providing powertrain components to multiple OEMs

If you are a powertrain supplier looking to add range extender solutions to your product portfolio — CREEV built and physically integrated a compact rotary engine with a generator, ready for evaluation and licensing. The EV market grew 1300% in two years before this project, and OEMs are actively seeking compact extender tech for their platforms.

Light Commercial Vehicle & Urban Logistics

mid-size

Target: Manufacturers or fleet operators of electric delivery vans and urban logistics vehicles

If you operate or build electric delivery vans where cargo space is non-negotiable — existing range extenders eat into your payload area. CREEV's compact rotary engine was specifically designed for vehicles where space is at a premium, fitting within a mounting frame without sacrificing cargo or cabin room. The estimated market opportunity was €79m over 6 years.

Frequently asked

Quick answers

What would licensing or purchasing this technology cost?

The project data does not include specific pricing or licensing terms. CREEV is patent-protected technology developed by an SME (Advanced Innovative Engineering UK), so commercial terms would need to be negotiated directly with them. Based on available project data, the estimated total market opportunity was €79m over 6 years, suggesting the technology is positioned for volume OEM supply rather than one-off sales.

Can this be manufactured at industrial scale?

The project's explicit goal was to 'scale up for market readiness.' Phase 2 SME Instrument funding was specifically for demonstration and scaling. The deliverables show a fully integrated unit within a mounting frame, indicating the design is moving toward production-ready form factor. The team reported over 100 years' combined experience in engine technology.

What is the IP situation — can we license this?

CREEV uses patent-protected innovations applied to rotary (Wankel) engine technology. The IP is held by Advanced Innovative Engineering (UK) Limited, the sole consortium partner. As a single-SME project, IP ownership is straightforward — licensing discussions would be with one company only.

How does this compare to existing range extenders on the market?

According to the project data, existing range extenders are 'too large with poor power density, limiting their use in small commercial and domestic vehicles.' CREEV's rotary design claims significantly improved power density with low emissions, low noise, and low vibration compared to conventional piston-based extenders. The technology specifically targets the compact vehicle segment that current solutions cannot serve.

What stage of development is this — can we test it now?

The project delivered a fully integrated CREEV unit within a mounting frame and completed physical integration of the engine system and generator. The solution was lab-tested before Phase 2 and advanced through demonstration during the project (ended November 2018). Based on available project data, the hardware exists for evaluation, but current production status would need to be confirmed with the company.

Is this technology compliant with European emission regulations?

The project specifically targeted low-emission operation as a core design requirement. The EuroSciVoc classifications include air pollution engineering. However, specific emission test results or regulatory certifications are not detailed in the available project data — compliance status should be verified directly with AIE UK.

Consortium

Who built it

This is a single-company project — Advanced Innovative Engineering (UK) Limited is the sole partner, an SME with industry classification. The 100% industry ratio and SME status mean this is a commercially-driven effort, not academic research. With no university or research institute partners, the technology development was fully in-house, which simplifies IP ownership and licensing negotiations. The team's reported 100+ years of combined engine technology experience and existing links with OEMs and Tier 1 suppliers suggest established industry relationships. For a potential business partner, this means you'd deal directly with one decision-maker who owns the IP outright.
