Prospeed Motorsport has developed the HILOAD 6x6 Rapid Intervention Vehicle, equipped with a Coldcut Cobra system, to tackle the challenges of extinguishing electric vehicle battery fires, offering a more efficient and effective solution than traditional methods.

With more electrified vehicles on the road than ever before, there's a higher risk of battery fires, which are significantly more challenging to deal with than fires from ICE (Internal Combustion Engine) cars. The UK-based Prospeed Motorsport has developed the HILOAD 6x6 Rapid Intervention Vehicle (RIV) to solve this concern.

Prospeed Motorsport uses a Toyota Hilux as a base vehicle and equips it with a brand-new 6x6 chassis and a torque splitter system. The modified machine has a 5,600-kg (12,346 lbs.) gross weight, with a maximum payload of 3,000 kg (6,614 lbs.). It's quite an upgrade from the standard 4x4 Hilux, as it can carry three times more weight. Moreover, the resulting low center of gravity enables the HILOAD to have better stability in high-speed situations.

The load space is increased by 1,230 mm (18 inches) to make room for all the necessary equipment. What's more, with a total height of just 1,850 mm (almost 73 inches), the HILOAD can fit in most parking structures.

What kind of equipment do you need to tackle EV battery fires? One solution Is the Coldcut Cobra system – the Cobra Ultra High-Pressure Lance (UHPL) system uses an abrasive suspended in water can pierce through floor pans and inject water through the battery's module casing at 300 bar. For comparison, that's 100 times the pressure of the air in a car tire. The water cools the battery's inside and can stop thermal runaway dead in its tracks.

Conventional methods of dealing with an EV fire involve pumping thousands of liters of water into the vehicle until the battery cools. The problem with this method is that batteries are tightly enclosed, and it takes a long time for them to cool down. The Swedish Civil Contingencies Agency demonstrated that using the Coldcut Cobra prevents cell system propagation within 10 minutes, with only 240 liters (63 gallons) of water utilized – that's 20% of the HILOAD's tank capacity.

Even though it's significantly modified, its maker says the HILOAD provides a normal driving position, with comfort levels like those of a standard car. Other notable features include a double cabin, an automatic gearbox, and hydraulic power take-off from the engine bay. Furthermore, Prospeed boldly claims, "There is nothing in the marketplace that has the capability of this vehicle."

The HILOAD is currently being trialed in the Czech Republic, where it's used to tackle EV battery fires, as well as assist with fast response occupant extraction.

Prospeed is also working on offering a 4x4 HILOAD with a 5,000-kg (11,023 lbs.) gross weight and a 6x6 variant with a 6,500 kg (14,330) gross weight in the defense market. They will be part of a light utility vehicle fleet, aiming to replace older Land Rover Defender and Pinzgauer fleets. It can have a wide range of uses, such as an ambulance, mobile command post, and more.
