NSW police will replace an ageing fleet of Australian-made Ford Falcons and Holden Commodores with a suite of new European and American cars from July this year.

The Traffic and Highway Patrol Command announced they will be adding a fleet of BMW 530d and Chrysler SRT Core vehicles, with both cars "exceeding" performance standards.

With a 6.4 litre Hemi V8 under the bonnet, the Chrysler is capable of screaming from 0-100 km/h in just over 4 seconds and boasts a top speed of 282 km/h.

A consumer model retails from $60,000, but its expected fleet pricing and technology modifications will put the vehicle on a different price level for the State Government.

The Chrysler-branded vehicles will replace the outgoing eight-cylinder variation of Highway Patrol's current fleet of Commodores.

NSW Police chose the Chrysler after an "exhaustive and comprehensive" global search, which included rigorous testing of 17 vehicles from around the world.

The BMW 530d – which in its normal guise costs just under $120,000 – will be used for general duties and was chosen for the European automaker's rich history in building police cars.

With a twin-turbo 3-litre diesel engine under the bonnet, the 5-series sedan is capable of producing 195 kW of power and a 0-100 km/h time of 5.7 seconds.

Both vehicles will be heavily modified to accommodate for police equipment, including sophisticated radar systems, auto-detecting numberplate cameras and online connections to police databases.

Assistant Commissioner Michael Corboy said both vehicles will help police reduce the road toll in NSW.

"The safety of our police officers and the community they serve is our top priority, and both these vehicles demonstrated the safety levels meeting our requirements," said Corboy.

"Equally as important, the platform of both vehicles supports the state of the art technology that is key to the government’s focus on reducing the incidents of road trauma across New South Wales."

Corboy said the cost of automotive production in Australia forced the Command to source fleet vehicles from overseas.

"As everyone is aware, there is no manufacturing of vehicles in Australia anymore," said Corboy.

"With the demise of the Falcon and the Commodore brand, NSW Police looked all over the world for replacements for those vehicles which have served this state well over the past 30 years."
