Ford police car doors to stop armour-piercing bullets
Two layers made from ceramic tile and Kevlar material provide a barrier to AK-47 calibre ammo.
The doors are designed to stop a .30-calibre bullet shot from a high-powered rifle like an AK-47. That’s more powerful ammunition than many soldiers carry.
Ford has offered factory-installed ballistic panels on its police car doors since 2008. But previous versions protected against handgun fire and non-armour piercing bullets.
Between 5% and 10% of police vehicles Ford sells have the optional ballistic protection, which costs around $1,500 per door.
But Randy Freiburger, a Ford engineer who works with police customers, said the company was getting frequent requests for better protection, particularly from police in the Middle East and Eastern Europe. So engineers starting working on upgraded panels.
“In some places outside the US, they face the armour-piercing threat on a daily basis,” Freiburger said. “This is the price of entry for those markets.”
Ford was also facing pressure from its rivals. Dodge began offering non-armour piercing protection on police versions of the Charger in 2012. Ford controlled 60 per cent of the US police vehicle market in 2015.
Other automakers, including Land Rover and Audi, make vehicles from high-strength steel that can protect against armour-piercing bullets. But the cost would likely be out of reach for most police departments. The armoured Range Rover Sentinel, which is not sold in the US, starts at $569,000. A Ford Police Interceptor SUV – which is based on an Explorer – starts around $30,000.
Ford’s ballistic panels – which cover most of the door – have two layers. The outside is made from ballistic-grade ceramic tile. When a bullet hits the tile, it disperses the energy and starts to break the bullet into pieces. The inner layer is made from aramid fibre, which is the same material used for Kevlar. The fibre catches the shrapnel from the bullet.
If bullets strike twice in the same spot, which is rare, the panels will still offer some protection, Ford says.
Freiburger said increasing the ballistic protection was an engineering challenge. The composition of the ceramic tile and the interior fibre had to be changed. The doors also weigh more, so engineers had to make sure that the hinges would hold them.
Ford will continue offering both non-armour piercing and armour-piercing doors for departments with different needs. Pricing for the upgraded protection hasn’t been announced.
The doors aren’t available to the public. In fact, they’re destroyed when police cars are scrapped so they can’t get into criminals’ hands.
Freiburger said the car windows do not have ballistic protection because it significantly increases the weight of the glass. Bulletproof glass could also make it more difficult to get injured people out of a patrol car.
Bill Johnson, executive director of the National Association of Police Organizations, said police are frequently targeted when they’re in their cars, so they will likely welcome the more advanced protection.
“Any kind of protection that can be added into the vehicles that officers are driving in is a great idea,” Johnson said.
