The BMW M135i, with its eye-catching paint job and shiny black wheels is on loan from BMW for trial as an addition to its elite ‘interceptor’ team.
The £31,000 car, with its unusual metallic blue, yellow and black colour scheme, has also attracted much debate on the internet site Twitter. The M135i is known as the ‘pocket rocket’ among fans, because it offers blistering performance in a car smaller than a Ford Focus.
A 3-litre turbocharged engine produces a massive 315bhp, enabling it to reach 62mph in just 4.9 seconds with the optional sports transmission, although normal civilian versions have their speed limited to 155mph.
But the other bonus is that it is the only small hatchback available with rear-wheel drive, which is preferred by expert drivers for offering keener handling.
West Midlands Police tweeted that there were no plans at the moment to introduce the model to regular patrols, but said it looked like an interesting concept.
