The US’s First Electric Fire Truck Includes A 300bhp Backup Diesel Engine

The BMW-sourced six-cylinder will recharge the battery if the truck’s battery runs out of juice
The US’s First Electric Fire Truck Includes A 300bhp Backup Diesel Engine

The Los Angeles Fire Department has taken delivery of an electric Rosenbauer RTX fire truck, making it the first fully operational electric fire truck to be adopted in the US.

The fire-stopping EV costs around $1.2 million (£996,700) per unit and uses two electric motors to produce 360 kW (roughly 490bhp) of peak performance and 260 kW (around 250bhp) in everyday driving. To power the immense machine, the RTX uses a gigantic 132kWh battery pack, which also supplies power to the truck’s four wheels and onboard equipment. For perspective, the Rosenbauer RTX’s battery is five-and-half times the size of the Fiat 500e city car’s 24kWh unit.

Despite the enormous battery pack, the truck has also been installed with a not-so-emissions-free 3.0-litre 300bhp BMW-sourced six-cylinder diesel engine. Austrian manufacturer Rosenbauer claims that “purely electric and therefore emission-free, short-range operations are not a problem” for their truck, but the traditional diesel power unit will will be used as a backup generator on long-distance journeys or more demanding missions to recharge the battery or power the water pump and other onboard systems. After all, the last thing you want to hear is that the fire truck has run out of battery on the way to your burning building.

During the new truck’s unveiling, LAFD Fire Chief Kristin Crowley claimed the new battery-powered truck would provide benefits such as “reduced noise” and lower overall diesel emissions, which will create a healthier working environment for the department’s firefighters. The Californian firefighting department has another RTX on the way for next year, while the city of Rancho Cucamonga has also placed an order with Rosenbauer for their own battery-powered fire truck.

“132kWh battery pack” and “purely electric and therefore emission-free” are the kind of dishonest arguments i really don’t like to hear.
Just give any other argument, like, the electric motors have a lot more torque than an average diesel engine, so more liters of water and more equipment can be carried in this truck. Or something like how the electric motors are a lot quieter than regular diesel engines, making the truck less noisy while driving on the street. Or maybe the instant torque of the electric motors can help the truck accelerate faster from a standstill, so it would arrive faster to the destination.
There are so many genuine arguments to make. A battery that size is no way near, not even remotely close to being “emission-free”.
And also it’s not electric, but instead it’s the range extender subtype of a series hybrid.
If it has an ICE that doesn’t put power to the wheels, but provide electric energy to an EM, it’s a series hybrid.

Agreed, and lets be real. It will spend most of it’s time with that ‘back up’ engine on anyway

It’s a hybrid drivetrain, nothing too special.
