A fuss has broken out following the latest Euro NCAP crash test results, which we published last week (issue 835). BMW's new 5-Series got four stars, but only after the German firm learned of the outcome, modified the car and had it retested. Now it's annoyed that details of the revamp have been made public. Work was done on the steering column, door trim and airbag. A spokesman said: "BMW takes Euro NCAP tests very seriously, but is concerned the specific changes appear to have been released."
