The Hyundai Sonata is a very good car with lots of interior room, large trunk, comfortable seats, great legroom in the front seats, easy to understand and operate controls. Base model comes with most options one would want on a car. Gas mileage averages 30 mph. Best of all, it can be bought new for less than 20K.
I research cars for a couple of years before buying, and this time around I had a list of 12 sedans and SUV's that I slowly eliminated through test drives until ending up with the Sonata Eco. I have 1000 miles on the car and am extremely pleased with it. Before buying, I drove a base model Sonata for a week as a rental and liked the feel of the car. It rides well, has a lot of features, and the build quality is excellent, but it's a bit slow to accelerate, around average for large sedans. I've followed dual-clutch transmissions for a few years, so the Eco intrigued me. It comes with 1.6L engine with a dual scroll turbo that runs great on regular gas, and a dual-clutch transmission. For those who are unfamiliar, it's a computer-controlled transmission that works something like a manual, but the computer can shift considerable faster than a human. It's also faster than a standard automatic transmission, though not as smooth. The engine produces 179 HP, less than the base model, but 195 ft-lbs of torque with a wide max torque band starting at 1500 RPM. The lighter engine and transmission drops the curb weight from 3587 for the base to 3219 for the Eco. The combination of a faster tranny, max torque at 1500 RPM, and less weight means that the Eco cuts about .7 seconds off the 0-to-60 time, and in high-speed driving, it accelerates beautifully. It passes slowbies in the fast lane like they're not there. It's hard to believe that you can get performance this good out of an engine whose combustion chambers are smaller than a half-gallon of milk. The Eco also gets outstanding mileage - rated at 28 city/ 39 hwy vs 25/36 for the base - if you can resist putting it in sport mode and driving with a heavy foot. Best of all, since the car hasn't caught on yet, you can get good deals on it. I got mine for $4015 off the MSRP. The speakers and the radio are great - it comes with a Sirius XM radio that sounds wonderful. My last two cars were a 2006 VW Passat 2.0T and a 2014 Mazda 6, both really good cars, but I like the Sonata Eco even better.
I rented a 2017 GLS model with the 2.4 liter 4 cylinder engine. We took it to Columbus Ohio from TN, so I had some time to get aquainted with it. The car only had 3 miles on it when we started off. It got pretty darn good gas mileage. I averaged 35.1 Mpg for the whole trip, that included city, highway, and idling for a while. However it seems the gas mileage came at the cost of power. Which happens, but the lack of power from the engine was very agravating while trying to merge in city traffic. The lack of ANY grunt at city speeds got old quick. Highway was ok. The seats are ok for short trips, but seemed uncomfortable to me for long trips. I mean, you have to get out and stretch on long trips, thats a given. But the seats were just plain uncomfortable after about 45min-1 hour of driving. The instruments and dash were pretty nice and oriented well. AC was great. Radio/bluetooth were great. Lights and steering were good. Glad it has a blindspot mirror installed. The windshield was a little short for me and im 6'2. I had the seat adjusted as low as possible, still had to lean it back a bit. It would be a great highway car if it were just more comfortable. For stop and go and city merging, it needs more grunt. Overall id say it would be a good choice for getting you to work and dropping the kid off at school. But not for trips unless you pack icy-hot and ibuprophen.
