Love the look of my K5 EX, but definitely wish our line had the fully digital dash layout that Hyundai already has. Other than more HP, it's about the only thing I would want to add to her. :)

Interestingly, Kia offers the full digital display in S.Korea on the EX with the upgrade package.
Home market K5’s also come with a rotary knob gear selector.
They obviously figured Americans were not ready to not have a physical shifter.

It’s noteworthy that you would not be able to manual shift the K5’s eight speed automatic with no paddle shifters, and no traditional gear shifter mechanism.
Note: The K5 GT does have paddle shifters.

I like both in my K5 just the way they are.

But the changing lanes display in the digital version is valuable.
The digital dash becomes available on the Sonata SEL Plus, and must have the convenience package option. iirc

As far as power, if the turbo’s boost pressure accidentally goes up 2-4 psi, say a mystery malfunction, you’re looking at 220 -230hp. Long-term reliable horsepower. The factory boost is kept low to make the fuel mileage high in CAFE testing. Just run top-tier, premium fuel only.

Hyundai released the pricing and specs for the Sonata N Line.

Sonata N Line - $33,200*

Sonata N Line with summer tires - $33,400*


2021 Sonata N Line Overview

  • All-new powerplant for the most powerful Sonata ever
  • First N Line trim for Sonata
  • Smartstream 2.5-liter turbocharged four-cylinder engine producing 290 horsepower and 311 pound-feet of torque
  • New N Eight-Speed Wet Dual-Clutch Transmission with paddle shifters
  • N Line suspension tune with available 19-inch Continental ProContact summer tires

FOUNTAIN VALLEY, Calif., Nov. 6, 2020
– Hyundai today announced that the 2021 Sonata N Line adds N Brand design elements, chassis upgrades, and an exclusive Smartstream 2.5-liter turbocharged engine mated to a new N Eight-Speed Wet Dual-Clutch Transmission (N DCT) to a SEL Plus trim Sonata. “N” signifies high performance at Hyundai, and our latest creation is the 290-horsepower Sonata N Line sedan. Available at most dealerships in November, the Sonata N Line will be priced at $33,200.

“Consistent with our N Line Philosophy, the Sonata N Line will bring 290 horsepower and performance to the street,” said Olabisi Boyle, vice president, Product Planning and Mobility Strategy, Hyundai Motor North America. “It is composed and responsive on the road and quick with its turbocharged 2.5L engine. On a twisty road, you can move through tight turns confidently and be thrilled with its capability.”

Sonata N Line Powertrain
Based on the 2020 Sonata’s new 2.5-liter four-cylinder engine, the N Line version adds a turbocharger, a different cylinder head, and unique internals. These changes put the horsepower at 290 at 5,800 rpm and the torque at 311 lb.-ft. at 1,650-4,000 rpm. These numbers are a significant increase over the standard Sonata’s 191-horsepower 2.5-liter four-cylinder engine or its optional 180-horsepower turbocharged 1.6-liter four-cylinder engine.

  • All-new design and engine structure
    • High tumble combustion system
    • High volumetric efficiency
    • Exhaust manifold integrated cylinder head
    • Piston cooling gallery
    • Split cooling and cross flow cooling system
  • Enhanced fuel efficiency

N Eight-Speed Wet Dual-Clutch Transmission
Hyundai developed the new N DCT with manual or fully automatic modes and eight speeds for improved acceleration and efficiency. The N DCT is equipped with electronic actuators that operate the dual clutch, providing ride comfort, fuel efficiency, and driving fun. Unlike a dry dual-clutch transmission, the wet N DCT uses oil to significantly improve lubrication and cooling performance, as required of higher-torque applications. The wet-type dual-clutch transmission uses an electric oil pump for increased thermal endurance and reduced direct parasitic drag on the powertrain. The N DCT was fully developed in-house by N brand engineers, with a fun-to-drive tuning focus. This transmission is similar to the one found in the high-performance 2021 Veloster N.

N Power Shift
N Power Shift (NPS) engages when the car accelerates with more than 90 percent throttle demand, mitigating torque reduction by using upshifts to deliver maximum power to the wheels through each gear change. This gives the driver a responsive feeling of dynamic acceleration when shifting.

Driving Experience Customization
Along with other updated features, such as Rev Matching and Launch Control, Sonata N Line is optimized to automatically sense driving styles and road conditions to optimize shift points. For example, the car will hold lower gears longer during performance driving for better acceleration out of corners. Conversely, if the driver is aggressively pushing the car on a twisty road, the car will use the full range of available engine RPM to maximize performance. All of these features can be configured in Sonata N Line’s improved infotainment system, using the latest operating system shown on a high-definition 10.25-inch display.

N DCT Engineering
Sonata N Line’s N DCT transmission employs two clutch assemblies, one for odd gears and one for even and reverse gears. The clutch actuator assembly utilizes a lightweight electric motor-driven system for greater efficiency, optimized shift response, and compact packaging. It also deploys an external damper for improved NVH (noise, vibration, and harshness). The N DCT uses an electromechanical gear actuator, yielding a lightweight design, higher fuel efficiency, and precise shifting control via the engine’s electronic control unit. The N DCT gearing assembly uses hollow input shafts for an ultra-lightweight and extremely responsive shifting character.

Sonata N Line Design Elements
The Sonata N Line has a unique body kit with a deeper front fascia and four exhaust outlets instead of the standard Sonata’s two. Inside, shoppers will notice bolstered sport seats and N Brand red stitching throughout. The digital instrument display changes when switched through driving modes, which include Normal, Sport, Sport +, and custom. In addition to changing the cluster, toggling through them alters the steering weight and the speed and strategy of the transmission’s shifts.

N Line Exterior Design Elements (Sonata N Line build upon the well-equipped Sonata SEL)

  • N unique 19-inch alloy wheels
  • 245/40 R19 all-season tires or optional 245/40 R19 summer tires (warm weather regions)
  • N front and rear fascias
  • Rear spoiler
  • Panoramic sunroof
  • Glossy black side mirrors and window surround
  • N dual exhaust with quad tips

Blue Link®

The new Sonata N Line features Hyundai’s Blue Link connected car system, which uses embedded telematics to allow drivers to remote start their vehicle and control interior temperature using the MyHyundai smartphone app. The app also allows users to either remote lock or unlock their doors and to find their vehicle in a crowded parking lot with Car Finder and remote horn and lights.

Digital Key
Continuing to promote the latest advances in technology, the all-new Sonata N Line has an optional smartphone-based Hyundai Digital Key. Digital Key uses a dedicated mobile app, Near Field Communication (NFC), and Bluetooth Low Energy (BLE) technology to allow a Sonata to be unlocked, started, and driven without a physical key, via applicable Android smartphones. Sonata’s Digital Key also allows secure sharing of virtual keys with family and friends.

I just the Thornton stage 3 tuner on mine. It claims 60hp. I’ve only driven a couple miles with it and can tell some increase in power. But would be hard pressed to believe it’s 60hp. But it also says to drive it 150 miles for it to fully make adjustments so we’ll see. Going to look it over maybe tomorrow and see if it has a turbo baffle. I know deleting that off my Forte5 SX gave it a little more pep. Thinking about doing a peddle commander. I heard it does help with the lag. I’ll try to remember to let you know about the tuner when I get the miles on it.

So now that I have some miles on this tuner I can say it definitely makes the car quicker. Turn off the traction control and she can smoke the sticky Perelli tires. Even with the TC on and in sport mode it’s hard to not light them up when taking off quick. Haven’t put her on a dyno so I can’t say it’s 60hp (waiting till after someone comes out with an intake and a more free flowing exhaust) but it is definitely more than stock. I’d say worth the $80. It has not triggered and warning lights and I’m seeing MPG in the 40s. My Forte SX couldn’t even do that.
