Interior noise is one area where the Elantra SE's low price becomes less surprising. The outside noise penetrating the cabin isn't horrible, but with the pronounced road rumble there's no question regarding this Hyundai's economy car status. What's more intrusive is the engine. At highway speeds the tachometer is registering about 3,000 rpm, a number that's pretty common, but in the Elantra sounds more like 4,000 rpm. At that point, what's going on under the hood is forced to the forefront of the driver's mind. That being said, the tires, usual culprits when it comes to offensive interior noise, remain largely quiet, emitting only the slightest chirp when pushed to their limits.
