I am wondering if an auto is faster on the highway while spraying assuming both cars are setup the same?

 

Faster (assuming you have enough power) is all about gearing. I'm assuming with a decent shot you could redline most if not all Hyundais regardless of transmission in their top gear.



If you mean quicker, a manual would still accelerate faster generally.

 

Depends if the hyundai auto trans explodes or not



But seriously, they have less gears and more internal losses. The auto will almost definitely be slower.
