An Alpina B4 has been spotted testing which will please many people. In the past they have created some interesting vehicles include a D3 Bi-Turbo which was a tuned diesel 3-series and it worked out very well. They are not massively aggressive looking cars but they certainly have some power under the bonnet.
The car seen in testing looks fairly tame with the only real changes that could be seen to the wheels and spoiler. However, there are rumours that something exciting is happening under the hood. It has been said that it will be a twin-turbo straight six that has been tuned to 410 horsepower. That suggests that it will be able to do 0-62 in 4.2 seconds and manage to get up to 190 mph as a top speed. It is expected that rear wheel drive will be the standard but there may be an all-wheel drive option as well.
It is expected that the next BMW M4 will be amazing but this Alpina B4 may certainly give it a good run for its money and could be more exclusive and stealthy.
