What is this zombie movie?

I only saw a bit of it on TV a while back, but all I remember is there was a big black man and he was a zombie ((very scary)) and he had some guy trapped in a car and kills him with gasoline/fire or however you wanna put it. I only caught that dead end part of the movie, so I have no idea which movie it was considering I don't watch many movies. Anyone know what I'm talking about?
