Does our 2011 have 375 or 385 hp?

So title. Our car has a 2010 engine in it since about 2 and a half years ago as my dads 2nd ex wife was an idiot and destroyed the original engine (for those interested, she ran over a large speed bump too fast and ripped the oil filter off and kept driving with no oil, yeah she was stupid but that’s besides the point)

So the VIN on the new engine comes back to a 2010. So I know for 2011 or mid year 2010 they bumped the 4.6 from 375 horsepower to 385 horsepower.

So does our car with a 2010 engine have 375 or 385 horsepower?

As far as I know my 2011 4.6 is 378 HP if I put 87 gas in. And it is 385 HP if I put premium 93 gas in. It is 7 horses difference.

If you really want to find out about your 2010 engine I would call Hyundai corporate with your VIN and ask them if you engine is updated one.

Thanks for the reply!

Did a little research and the car the engine came out of appears to have a bios date of April 18, 2010.

I’m seeing here in the forums that the change was done mid April 2010 or March 2010.
