Every piece of literature says its the 1.8L in my car, yet the sticker under the hood says group xxxx2.0xxxxx... what gives? Anyone know how I can verify if it is indeed a 1.8L and maybe they put the wrong sticker on my car?

 

I don't know what sticker you are looking at but your car does not a have a 2.0L engine. It is, in fact, the 1.8L Nu engine.

 

its supposed to be the 1.8L Nu engine actually. This sticker is on the underside of the hood, the Emissions sticker. I will take a picture of it and you'll see.

 

Elantra Coupe 2013 here with same label, a friend of mine have an 1.8 and the label says 1.8 on group but mine says 2.0. Ok the thing is that Im researching and the only thing I can think of is that "maybe" can be the 2.0Nu **MPI** engine. Why I get to this? and Im not saying this is what it is but maybe there is a chance because it seems to be that the 2.0Nu MPi is the same 1.8 , same cylinder bore and compression ratio BUT the 2.0MPI has a longer stroke of 97mm aprox.(1.8Nu have a 87mm stroke) and maybe some tune to compensate.

thats my 2 cents of my crazy ideas, but think about it, research it
