In the United Kingdom, the police usually do not carry weapons when they are on duty on a daily basis, and in the event of an emergency, the BMW 3 Series police car will generally intervene quickly to respond, which is used to hunt down and intercept criminal vehicles at high speed to undertake emergency tasks such as transporting firearms and personnel. In 2010, BMW became the "core supplier" of the British Police Force for the first time, and the BMW 330d Saloon Interceptor pictured below was selected as the "high-performance pursuit vehicle" of the police force at that time.
3 series police car was first equipped with N57 series three-turbo inline six-cylinder engine, combined with BMW short front suspension rear-drive design, the control is also very good, around 2015, the British Police Force, the original N57 series of three-turbo inline six-cylinder engine 3 series has been replaced by B57, this engine also appeared in the Dakar Rally MINI JCW, equipped with the same B57 inline six-cylinder diesel engine MINI JCW, torque can exceed 800Nm, At the same time, the B57 series four-turbocharger in-line six cylinder is also BMW's pinnacle product.
However, the British police force is still equipped with a large number of N57 series of three-turbo inline six-cylinder engine 3 series police car, in addition to the BMW 3 series, the British police force is also equipped with 5 series, X5 models, these vehicles because of the task needs, and civilian cars are different, police cars have canceled the electronic speed limit, but recently the British police force can be described as talking about horse discoloration, these N57 engines to the British police force has brought a lot of trouble.
According to british media reports, from Kent in 2016, Liverpool in 2019, South East London in 2019 and Swindon in 2021, as well as in December 2020, a police officer in Cumbria killed a police officer while on a mission. According to reports, this series of accidents has led the British police force to fully order that the police force must not use BMW police cars equipped with N57 engines for high-speed pursuit missions. At present, the Force can only awkwardly use the 1.2 L small displacement peugeot with turbocharged Peugeot as a support vehicle for the time being.
After several fires, BMW also gave an answer to this question, because it is related to the special way the police operate these high-performance vehicles. Perhaps due to excessively drastic accelerations and the additional pressure on certain components due to the removal of electronic speed limits, BMW will have a special maintenance plan for BMW models that are still in service with the N57 engine in the police force, while BMW also said in a statement. "Civilian models using N57 engines don't have to worry too much, and there is no need to adopt a maintenance plan for any civilian vehicles." But the British Police Force chose not to touch these BMWs, and now the Police Force has turned its attention to the purchase of Volvo.
