London police are putting the cuffs on emissions with new fuel cell police cars.

The Metropolitan Police Service is getting 11 Toyota Mirai fuel cell vehicles. The first have arrived in the force’s rollout of the world’s largest hydrogen fuelled police car fleet.

The Mirais will be able to fill up at five hydrogen filling stations across London, although that number is expected to grow. The cars can cover around 300 miles on a tank of hydrogen.

Met Commander Neil Jerome said: “We are delighted to have taken delivery of 11 of these cars to support policing in London. They are our first entirely zero-emission response vehicles and this is an exciting development for us.” Jerome added that “this is enabling us to make great strides towards our ambition of procuring 550 vehicles as zero or ultra-low emission by 2020.”

The new Mirais will be used as both marked cars – wearing the force’s iconic Battenburg markings – and as unmarked cars. The Mirai might not seem like the ideal pursuit car with a 0-60 time of 9.6 seconds, but it’s tougher to outrun the police radio and the city’s camera network.

The first batch of cars was funded with the support of the Fuel Cells and Hydrogen Joint Undertaking. A public-private partnership that supports the research, development, and demonstration of fuel cells and hydrogen energy in Europe.

The Toyota Mirai was introduced in 2014. The car is powered by a hydrogen fuel cell that emits only water from the tailpipe. It’s a big reduction compared with the gas and diesel-powered cars the force is using currently. It’s also a chance for Toyota to gather massive amounts of data from vehicles that will likely see some of the harshest conditions around in the constant short trips and long idle periods police cars endure. The cars also add high-profile visibility to the Mirai.

“We are delighted that the Met Police has added Mirai vehicles to its fleet.  The distinctive livery of the Met’s marked cars means even more public visibility for hydrogen powered cars in and around London,” said Mark Roden, director of operations for Toyota GB.

London is working to reduce the emissions from city vehicles and has set a target of becoming a zero-carbon city by the year 2050. Cars like these new Mirais are a big part of that goal.
