Not to mention, although the engine was quiet it still had mass and the noise created when it accidentally hit anything still caught attention. 

The zombies in the vicinity turned their heads in their direction, immediately going after them. Some were fast, while some were faster than others. 

These were zombies that had a high chance of turning to super zombies.
