Does Hyundai have the best 2.0-liter turbo on the market?

Hyundai’s 4-cylinder turbo seems to stack up well against the premium brands’ offerings. Here’s why.

Over the past year I have driven 2.0-liter turbocharged 4-cylinder engines from BMW, Volkswagen, Audi, Range Rover, Lexus, Ford and a handful of other car makers. This week I am testing a Hyundai Sonata Sport with the 2.0-liter turbocharged engine. What has become immediately apparent is that Hyundai may very well do this better than any other brand. Here’s why.

Hyundai Turbo Uses Regular Unleaded Gasoline
The whole point of moving to smaller turbocharged engines instead of continuing to refine larger normally aspirated engines with more cylinders was fuel economy. Fuel economy means the cost of fueling a vehicle. Fuel efficiency is related, but not the exact same thing. Hyundai’s 2.0-liter turbo is designed to use regular unleaded instead of the premium that almost every other manufacturer requires to get the rated output. Using regular instead of premium saves customers 10 to 15% at the pump with no downside.

Hyundai’s 2.0-Liter Turbo Responsiveness
While researching an Audi this week for another publication, I discovered that Audi seems to agree that most turbocharged engines suffer turbo-lag that is annoying at best. Audi says of its TFSI (2-liter turbo) engine “Audi is the first manufacturer in the world to engineer a turbocharged direct injection engine, which produces high power output and optimum engine response.” I’m glad Audi agrees that there is an issue with these engines, but having driven their engine in the new A3 recently I’m not feeling it. Like most small turbos the Audi, the BMW, the Range Rover and the rest all seem to hesitate noticeably longer than a modern V6 would when one toes the throttle. The turbo lag is made worse in some cases by transmissions with too many gears, 9 in some cases, or a dual clutch transmission, which I find to be sluggish in automatic mode.

Hyundai’s turbocharged engine seems to suffer less from turbo-lag than the other engines I have tried of a similar design. It’s six-speed automatic also seems to be a sane approach to an automatic. You may feel otherwise, but Hyundai seems to offer an engine just as powerful (245 hp) as the rest, but with better responsiveness.

Hyundai Turbo’s One Negative
If I had to pick one thing that Hyundai could improve upon it would be the exhaust note. The Sonata Sport I am testing sounds like a sewing machine, not a performance car. Hyundai should adopt the industry practice of either tuning that note using exhaust tricks, use a “sound inductor tube”, or simply fake it like BMW and others now do and just play me happy sounds through the speakers. I don’t care how it works. I just want my car to sound good, or simply be silent.

Conclusion
Ford also deserves kudos for doing much of the same things Hyundai is. Ford also uses regular unleaded in its turbocharged engines, and they too provide decent throttle response. Interestingly, the Escape I tested, and loved, also had a 6-speed automatic. Maybe the formula isn’t that difficult? In any case, it is nice to report that the mainstream, blue-collar brands are out in front of the premium brands when it comes to both performance and fuel economy in today’s modern engines.

In the name of "safety" mandated air bags maim and kill, and now, in the name of mandated fuel economy, turbo-lag can result in the same.
I own a 2013 Hyundai Santa Fe 2.0T. And for being an CUV/SUV. It is quick. There is turbo lag from a stand still if you were to floor it. While having to pass or merge on to the highway it is an instant response and do not have any regrets on the vehicles besides the lack of aftermarket support.The exhaust note I agree is not the most wonderful but the intake and engine sounds great when pumping out power.
You should contact SFR for ECU tuning because I believe the Hyundai 2.0T's are hitting close to 300whp (wheel!) with a tune which puts you at something like 330-350hp at the crank.
Would you please give more info on "SFR"? I tried SFR.com and got a French company. Are there others who offer adjustments to the ECU? I am very interested. Regards
Seoulful racing. I have their tun in my sante fe 2.0t. Along with a gfb turbo timer cold air intake and pipe and fron mount intercoller upgrade with bov conversion. as well and an uncle lap3 chip. Im parting out a turbo swap now but i hav 397 at the wheels at 6500 rpm
I've had a 2013 Sonata with the 2.0 Turbo and at 40k miles it was 1.5 qts. low of oil? I'm not a hard driver and I use Mobil One Synthetic oil on my oil changes regularly so why is it a oil burner. I now have a 2015 Santa Fe 2.0 Turbo and hope the oil issue is corrected.
Have just purchased a 2016 elentra gr hatchback wanna get a turbo kit for it any suggestions already putting 173 to ground wanna do about 350 thats all i need for a fwd vehicle
the current Hyundai 2.0 litre was development, between Mitsubishi, and Mercedes and Hyundai, Mostly from the 2.0 litre turbo, from the lancer evolution, from mitsubishi
Funny how there was no mention of the block being a Mitsubishi Lancer Evo design with intake and injection from Hyundai. No mention of the twin scroll design either to reduce lag. And btw, running regular gas will affect engine output....
I have a 2015 265 HP Turbo Ultimate Santa Fe It is a great vehicle. I get 31 mph on highway and it's full of pep. Rides good. Better than I expected
I have a 2016 Santa Fe Sport with Ultimate 2.0Turbo and AWD. Some articles list GO as 265 HP and others list it at 240 HP. Sometimes when slowing down the Transmission seems to not downshift correctly and it feels as if the vehicle hit a speed bump. Only happens when I'm ECO mode. The transmission was replaced and the problem continues worse than before happening up to 48 MPH. Any ideas or suggestions?
