The most common police cars here now are the police-model Dodge Charger, which is an SXT with no rev limiter, and the Ford Explorer Police Interceptor, which is an Explorer with the Mustang 5.0 litre engine.
Depending on what you drive, you might keep ahead of the Explorers, but those Chargers can beat most cars with ease.
In Ireland, they drive the deadly Hyundai i40....
But they do have some unmarked cars that are fast enough.
The thing is, there aren't that many really fast cars in Ireland....the green party got into power twice here and put so much tax on performance cars that only a tiny group can really afford anything outrageously fast.
If you took a V6 or straight 6 and tuned the car, you'd probably outrun almost everything on the road here.
The electric cars are actually some of the fastest here now.... I see a few Taycans and Audi e-tron GT's around (basically the same car underneath) and many Teslas too.
