Hi Everyone!

I just sold my 2012 Elantra with the 1.8L engine and took quite a beating on it but I did not enjoy the engine sound. They did allow me to drive the new 2017 Elantra and that engine is so smooth and so quiet. It's a whole new Elantra experience. I'm trying to find out, Hyundai used a 2.0L in some if it's sport models on the 2014-2015 models. Is this the same engine that is now standard in the 2017 or is it a completely different bird. I'm interested in a Sonata and some Sonatas come with a 2.0L engine instead of the 2.4L. Some of them even come with a 2.0L Turbo that pumps out 274HP. Oddly though, in 2015 the HP rating dropped from 274HP to 245HP. Does anyone know why? Smaller turbo? Different engine design? Typo? I've test drove a few Hyundai Sonatas. A 2012 that had 48K and the engine was very quiet and it drove perfectly smooth. Then I got into a 2015 Sonata with supposedly the same 2.4L engine but it was very tickish and it sounded bad and cheap even when driving it. And the last 2015 I drove with the 2.4L was so loud upon started and idle that I passed on taking it out for a test drive. There had to have been something wrong with that car. So, three Elantras with the 2.4L engine and they all sounded different. Is the 2.0L Turbo a better engine? Can you get the 2.0L engine in a Sonata without a Turbo? I was absolutely amazing at the new 2017 Elantra 2.0L engine so is it the same engine from the 2012 Sonata 2.0L? Or, is the 2.4L the better way to go on a Sonata?

In terms of your questions about the loss of HP, I'll try to answer with my limited knowledge and experience with the Sonata (both YF and LF Models). Unless you are driving around a track at speeds over 100miles/hour, you do not need 274 HP (Plus, that number is at the crank, so you'd be getting about 220-230sh at the front wheels on a perfect day). As daily drivers in city/highway combinations, what we'd need is a less turbo lag/better throttle response, with speeds 40-80 miles/hour. That is basically what Hyundai did on LF 2.0T, with a smaller turbo, better response, and better gas mileage.
I currently drive a 2.4 Sonata Sport, and you have to keep that car in "Sport" mode to get the best response. I still get 22-23 MPG in town, even when you push the car and get a little heavy foot on the gas. It has better throttle response and better handling than my YF Sonata Limited (again, in my opinion and my own experience, I respect if you or anyone else has different views).
I did not test drive an Elantra, especially the new Turbo should be exciting, my guess is that it'll be a similar setup as the Veloster Turbo.
I have tested both 2015 Veloster Turbo and 2015 Sonata Turbo. I skipped the Veloster since I like the Sonata design and cabin space better (Veloster is small, can't fit a family in there). For the Sonata Turbo, it was like a dream going down the highway with the paddle shifters and getting that Turbo feeling (I also had a 2013 Santa Fe 2.0T, loved it except the terrible gas mileage-I had the SFS 2.0T in Upstate New York for 2 years, and had an average of 16-18 MPG on cold months, mixed city/highway driving- which is terrible). But the lease price for Sonata was around $530-550/month, it was fully loaded and all, but again, I did not want to break the bank, and also, I would get a Genesis 3.8 AWD if I was willing to go $550-600/month.

Hope this helps, just wanted to share my experience, and hope you'll be able to get a new Hyundai soon.
