The vehicle in numbers
The Forefront is a flat, boxy field machine with no cab. Two electric motors drive all four wheels, the rear axle steers, and the payload is 1,000 kg. Renault quotes about 400 km (250 miles) on a charge and says an add-on range extender can extend that distance. The company did not say how much energy the battery holds, how much fuel the extender carries, or how fast the vehicle charges.
John Cockerill, the Belgian defence group, developed the remote-operation and autonomy functions. Its engineers took input from the French armed forces, which will run the vehicle through exercises and trials over the coming weeks. Renault says it will then refine the concept on operational feedback. The listed missions are logistics support, anti-drone work, fire support and evacuation; civilian access to dangerous sites is a secondary use.
What 400 km costs in battery mass
Nobody outside Renault has driven the Forefront. The 400 km figure is a manufacturer projection, not a homologated number, and there is no independent test to compare it against. Winter behaviour, which is where most EV range claims lose 20 to 30 percent, has not been mentioned at all.
We can still put a scale on it. A heavy off-road vehicle with permanent all-wheel drive and the aerodynamics of a shipping container will not approach a passenger car's consumption. Assume 30 kWh per 100 km. That is our assumption, not a measurement. On that basis, 400 km needs roughly 120 kWh of usable battery. At about 180 Wh per kilogram at pack level, the cells and modules alone weigh some 670 kg, before cooling, structure and the payload go on top.
How that compares with diesel
Diesel carries around 9.8 kWh of chemical energy per litre, so a 120 kWh pack holds the energy equivalent of roughly 12 litres of fuel. A diesel engine converts only about a third of that into work, so a comparable mission would burn closer to 35 litres. The electric drivetrain wins clearly on energy per kilometre and loses on mass and refuelling speed. That trade-off sits at the centre of every military electrification programme, and Renault has not published the figures that would settle it for this vehicle.
Silence is the product
An electric drivetrain makes no engine noise. For a machine meant to move through disputed ground without a crew inside, that is the point: no exhaust note to hear, and no driver to lose. John Cockerill's software allows either remote control by an operator or autonomous travel into areas considered too risky for people.
Autonomy claims are the hardest part to verify. Renault gives no detail on sensors, on what happens when the link to the operator drops, or on how the vehicle behaves off mapped terrain. The upcoming French trials are the first place those questions get answered.
Passenger-car parts, military pricing
Renault says the Forefront uses proven automotive components to keep costs and production times down. That is the same logic the group applies to its road cars. Renault's Scenic E-Tech carries an 87 kWh battery and claims around 610 km on the WLTP cycle, which works out at about 14.3 kWh per 100 km. Our estimate for the Forefront is more than double that, on a pack at least a third larger. You can browse comparable road cars in our EV catalog.
No price has been given for the military vehicle. Renault speaks only of competitive costs if enough interest appears.
Charging is the unanswered question
Nothing in Renault's release covers charging. A pack of this size in a field depot with no fixed grid is a different engineering problem from a motorway hub, and it is the one that decides whether a 400 km vehicle is useful or a demonstration. Heavy-duty charging infrastructure is being built for trucks first: Magna's truck hub in Austria splits 2.4 MW across all its connectors, which shows how much power a single site can absorb and how far that is from a forward operating base.
For scale on cost, take a public DC price of about €0.50 per kWh, which is in the range European fast-charging hubs charge today. A 120 kWh session would then cost roughly €60 and cover 400 km, or €15 per 100 km, before you count the vehicle or the crew. Run your own tariff through our charging cost calculator to see what a pack that size means on your bill.
Where the numbers still stop
Renault has built a concept, not a product. Battery capacity, charging power, extender fuel capacity, unit price and production volume are all unpublished. The trials with the French armed forces in the coming weeks will produce the first operational data, and Renault says the design will be refined afterwards. Until those results exist, the only firm figures are 400 km, 1,000 kg and two motors.
