The doors stay intact and functionalWhen Mazda introduced their new B-class car, the Mazda2, earlier this year one of the most interesting technical aspects of the car was that the company bucked the seemingly irreversible trend of making new models bigger and heavier. The new car is more than 200 lbs lighter than its predecessor. While many people (particularly SUV owners) seem to think that lighter cars are inherently less safe this doesn't necessarily have to be the case. The new Mazda2 has just completed its EuoNCAP crash testing and received the maximum five stars for adult crash protection and four stars for child protection. It's not clear why smaller children would fair worse than adults but the ratings are still very good such a small car.
