Volvo police carVolvo has form with police cars. Sure, your local bobby probably runs around in an Astra, while an unmarked BMW 5 Series is able to put the frights up any daring company car driver pounding up a motorway at 90mph. But the Swedish car firm has been making police cars since 1929 – and selling them to the British police since the 1960s.

Today, there are around 400 Volvo police cars on UK roads. The vast majority of these are V70 armed response vehicles or traffic cars. But, as the V70 is no longer produced, that could be about to change…

Volvo V90 police carVolvo V90 police car

Yes, say hello to the Volvo V90 police car. Here it is in Swedish livery, being tested on a frozen lake somewhere in the Northern Circle at a top secret military base. We say ‘tested’, that’s actually our man living out a childhood dream of driving a police car. On a frozen lake. Mostly sideways.

What’s the point of that?Volvo V90 police car

It’s not all in the name of fun and frolics. Honestly. Volvo’s test drivers spend at least 500 hours putting the latest police cars through their paces in hot and cold climates. The logic goes that if it can survive being driven hard in temperatures way below zero degrees, a pursuit through Bradford’s housing estates won’t phase it.

What’s under the bonnet?Volvo V90 police car

Under the bonnet of this V90 – and, indeed, all V90 police cars for now – is a standard four-cylinder D5 diesel engine. The twin-turbo unit produces 235hp and, before all the extra weight of the police equipment is added, propels the V90 to 62mph in 6.9 seconds.

What’s different, then?Volvo V90 police car

All Volvo V90 police cars are start off as standard cars, taken from the production line at the same point ordinary models are shipped off to dealers. But, rather than being loaded onto a transporter, police-cars-to-be are taken around the back of Volvo’s factory in Torslanda, near Gothenburg, and modified by the special vehicles division.

And what happens next?Volvo V90 police car

Here, a special team of converters spend around six days turning it into a cop car. A special boot frame is fitted to cope with all the gear carried by traffic officers (and prevent it flying forwards in the case of a rear-end shunt), while brakes are upgraded to help bring the heavyweight V90 to a stop. The suspension also gets upgraded, with a 300mm lift and firmer dampers. The wheels are replaced by XC90 alloys.

Is anything done in the UK?Volvo V90 police car

Once police cars arrive in the UK, they’re sent to one of a small number of specialist converters where the finishing touches are put in place. The correct radio is fitted, for example, while British ‘battenburg’ livery is applied to make it stand out.

Why are they so close to standard?Volvo V90 police car

Police cars are generally bought outright rather than leased, so police forces want to be able to get as much of their investment as possible back when it comes to resale time. As such, once you remove the kit fitted by Volvo’s special vehicles workshop, the V90 looks like pretty much any other model.

It looks rather luxurious insideVolvo V90 police car

Inside, it’s exactly as you’d expect a high-spec V90 to be. Leather seats are fitted (they wear better than cloth and are easy to wipe down), while the standard infotainment system is left in place (the aftermarket computer system that controls the blues and twos, as well as having its own sat-nav feature, is hinged to cover the standard system but can easily be lifted up).

Does it have holes in the roof?Volvo V90 police car

You used to be able to spot an ex-police car by holes in its roof where the lights were fitted. That’s not the case any more… everything is flush mounted, and cabling for the LED roof lights runs through the roof bars. All this helps when the police car has to be sold after retirement.

How long do forces keep police cars?Volvo V90 police car

Traditionally, forces would keep traffic cars for a maximum of three years and 100,000-150,000 miles. Now, budget cuts dictate that forces must keep hold of them for longer – as much as five years and several hundred thousand miles – so they need to be pretty robust.

How often are police cars serviced?Volvo V90 police car

Most police forces have their own workshop for routine servicing, which is carried out regularly, while some even invest in diagnostic equipment to enable more serious work to be carried out. Obviously, under routine police work the cars can be damaged fairly regularly – and for bodywork they’re usually returned to a local Volvo dealer.

What other challenges do forces face?Volvo V90 police car

Over the last eight or so years, all traffic cars have been diesel, with police forces keen to save money on fuel. As diesel becomes a naughty word and police need to be seen to be doing their bit, we could see a shift towards petrol or hybrid police cars. Indeed, with a plug-in hybrid T8 V90 on its way, it’d be fair to assume these might be pressed into police duty.

What about driverless tech?Volvo V90 police car

Volvo is big on autonomous technology, and safety systems such the firm’s City Safety automatic emergency braking could prove to be problematic. If a car will do everything in its power to prevent a collision, how do police carry out tactical stops that involve making contact with other vehicles? Fortunately, for now, the technology can be turned off…

And in the future?Volvo V90 police car

Who knows? Police cars are a tiny part of what Volvo does, so it won’t hold back on developing its driverless features for those rare occasions when traffic officers need to take control. Will we see driverless police cars? “Cars will outskill even police drivers,” Volvo’s special vehicles chief, Ulf Rydne, told us.

Will we see Volvo V90 police cars on UK roads?Volvo V90 police car

There are a few hoops Volvo has to jump through before we’ll see V90 police cars on the roads. It needs to be added to the Home Office framework, which means it’s approved for UK police forces. But as Swedish police have already tested the V90 and given it a 9.2/10 rating – higher than any other car ever – it’s unlikely that it won’t be approved in the UK. We ought to see V90 police cars patrolling our motorways by the end of 2017.
