Innovative Drop-In Range Extender Conversion for Electric Vehicles

Discover how Horse's new drop-in range-extender for EVs, the C15, revolutionizes electric driving with compact design and versatile fuel options.

Horse Unveils Groundbreaking Drop-In Range Extender for Electric Vehicles

As the automotive industry transitions towards more sustainable solutions, innovative technologies are emerging to enhance the efficiency and usability of electric vehicles (EVs). One of the latest advancements comes from Horse, a combustion engine engineering company backed by Renault, Geely, and Aramco. This exciting development is the Horse C15, a drop-in range-extender conversion kit designed to broaden the range and application of battery-electric vehicles.

Overview of the C15 Range Extender

The Horse C15 is a compact powertrain that comprises a naturally aspirated 1.5-liter four-cylinder engine, which works seamlessly with an integrated generator and inverter. With a power output of up to 94bhp, this innovative unit claims to be no larger than a briefcase, making it incredibly easy to install. It can be fitted in the 'frunk' (front trunk) of an EV or positioned at the rear either horizontally or vertically.

In addition to the standard model, Horse plans to offer a turbocharged variant aimed at D-segment models and commercial vehicles, capable of delivering an impressive 161bhp. The versatility of these engines allows for a broad range of applications, enhancing the appeal of EVs to a larger market.

Fuel Flexibility and Emissions Compliance

One of the significant features of the Horse C15 range extender is its compatibility with various fuels. This engine is designed to operate on petrol, synthetic fuels, ethanol, or methanol flex-fuel. This flexibility not only promotes a more sustainable approach but also aligns with the forthcoming Euro 7 emissions regulations, indicating a forward-thinking approach to environmental standards.

However, it's essential to note that these engines are not intended for driving a car's wheels directly. Instead, they are engineered to operate within the most efficient rev range for generating electricity, thus supplying power to the EV’s drive battery while minimizing noise, vibration, and harshness (NVH).

The Growing Demand for Range Extended Electric Vehicles (REEVs)

According to Horse CEO Matias Giannini, range-extended electric vehicles (REEVs) represent one of the fastest-growing powertrain categories across global markets. Giannini noted, "The Horse C15 range extender solution offers car companies a straightforward and cost-effective way to tap into this opportunity and adapt their native BEV platforms into REEVs. We believe demand for REEVs will continue to grow."

As the push for cleaner transportation intensifies, manufacturers are seeking viable solutions to extend the range of EVs. The C15 range extender offers significant potential for traditional automakers to evolve their existing models into more fuel-efficient and versatile platforms.

Advantages of Adopting the C15 Conversion Kit

1. Increased Driving Range

The integration of a range extender such as the C15 allows EVs to traverse longer distances without requiring a lengthy recharge. This increased driving range is critical for drivers who rely on their electric cars for long commutes or road trips, alleviating range anxiety.

2. Versatility of Fuel Options

Horse’s commitment to adaptability through various fuel types enables EV owners the freedom to choose their fuel source. By welcoming synthetic fuels and flex-fuel options, the C15 supports diverse energy strategies, accommodating users looking to minimize their carbon footprint.

3. Easy Installation and Compact Design

The briefcase-sized C15 range extender is designed to fit seamlessly into existing EV architectures, making the shift straightforward for manufacturers. This easy install process can save both time and resources during production and modifications.

4. Compliance with Future Regulations

As emissions regulations become more stringent, the C15’s compliance with Euro 7 standards positions it as a viable option for car manufacturers wanting to stay ahead of regulatory changes.

Conclusion: Embracing the Future of Electric Mobility

Horse's C15 range extender signifies a pivotal moment in the quest for sustainable automotive solutions. By providing a versatile, compact, and efficient power source, it empowers car manufacturers to enhance their EV offerings without a complete redesign. This forward-thinking technology is poised to shape the future of electric mobility and could potentially reenergize the market for electric vehicles.
