Corgi loaded their version of the Batmobile with several different features. It shot small plastic missiles out of it's three tubes mounted behind the cab, the exhaust flame juts in and out as the wheels roll to simulate fire, and the front of the car has a spring-loaded saw blade that tucks away when not in use.
One neat feature that Corgi incorporated is an embossed full-figure portrait of the Caped Crusader on the bottom of the car. I think this really speaks to the quality and detail that Corgi put into this product. I'm sure no one would have missed it if they hadn't included the image. However, for those that looked, it was a nice little bonus. Interestingly enough, Corgi also did this with all of their more recently released versions (2005-ish?)of the different Batmobiles, as well.
