Car Safety Review : Ford Ka vs. Vauxhall Astra For the purposes of our crash test, we had the Vauxhall driven by Yorkshiresoul in his normal ambling manner, i.e. about 40 mph in a 60 zone, the Ford Ka was driven (badly) by Miss X. The resulting impact shredded the passenger side tyre and mangled the front wheel and wheel arch on the Vauxhall, and dented the passenger door deeply enough for the speaker inside to pop out of its mounting, all four panels on the Vauzhall's passenger side were badly scratched and dented. The Ford Ka though, well it sort of dissolved. The impact removed pretty much everything attached to the front end of the car, lights, bumper, number plate, trim, and left the reminaing metal work and bonnet in an askew and tangled mess. In our unnoficial test, we rate the Vauxhall Astra as being safer than the Ford Ka, which is apparently built from styrofoam. Of course all cars would be safer if people actually looked before pulling out of side roads.
