How Much Does the 2018 Hyundai Ioniq Cost to Own?

Is It Better to Buy a Used or New Ioniq?

For the 2019 model year, Hyundai introduced automatic high beams and driver attention monitoring as optional features in the Ioniq. If you can live without those active safety features, consider a used model instead of a 2019 Ioniq. A new model likely costs thousands of dollars less. Prices for a used 2018 model range from around $19,000 to almost $29,000, while the 2019 model starts at $22,400 and goes up to roughly $37,000.

Which Used Hyundai Ioniq Trim Is Right for Me?

The 2018 Hyundai Ioniq comes in gasoline-hybrid, plug-in-hybrid, and all-electric versions. Choosing what's under the hood will be a matter of preference, depending on your driving habits, ability to charge, and prices you find for the car in relation to potential savings on fuel.

The 2018 Ioniq comes in three trims: base (Blue for the standard hybrid), SEL, and Limited. The base version comes with a solid number of standard features, but those seeking the most luxury will want to take a look at Limited trim models. These add leather seating and have more available driver assistance features.

What Does Hyundai's Certified Pre-Owned Warranty Cover?

Hyundai offers a certified pre-owned program for vehicles five years old or less and with fewer than 60,000 miles. Eligibility is determined by the vehicle’s initial sale date. Certified pre-owned Hyundai vehicles receive the balance of the original new-car 10-year/100,000-mile powertrain warranty, as well as the remainder of the five-year/60,000-mile comprehensive warranty. Hyundai CPO vehicles must pass a 173-point inspection. Additional benefits like towing, roadside assistance, and rental car reimbursement may be available, so read Hyundai’s warranty page carefully.

2018 Hyundai Ioniq Versus the Competition

Which Is Better: 2018 Hyundai Ioniq or 2018 Toyota Prius?

The 2018 Toyota Prius is probably the most famous hybrid on the planet. For a while, the Prius was the benchmark for models like the Ioniq. Now, the Ioniq squeaks out better gas mileage, on average. If you're looking at the Ioniq Plug-in Hybrid, you'll want to compare it with the plug-in Toyota Prius Prime, which gets slightly better efficiency ratings. The Prius has a more accommodating interior, with a little more cargo space and rear-seat room than the Ioniq. A bevy of active safety features are standard in the Toyota, and you can find models with cool available features like a brilliant 11.6-inch touch screen. These are both great hybrids that excel in fuel economy, so choosing one comes down to price and which one you like better.

Which Is Better: 2018 Hyundai Ioniq or 2018 Nissan Leaf?

The 2018 Nissan Leaf is an all-electric car that goes up against the Ioniq Electric. Fully redesigned, the Leaf touts a 151-mile range, compared to the 124 miles that you get in the Ioniq Electric. The average price for the Leaf is several thousand dollars higher than that of the Ioniq, so you'll have to decide if the extra driving capability is worth it. The Leaf also has some low-end cabin materials and lacks standard features like a touch-screen system. For everyday comfort and convenience, the Ioniq is likely a better bet.

2018 Ioniq Performance

How Does the 2018 Hyundai Ioniq Drive?

Powertrain options for the 2018 Hyundai Ioniq include hybrid, plug-in hybrid, and all-electric. All three feel smooth and zippy, though you don't get quite the same off-the-line punch in the Ioniq Electric as you do in some other electric vehicles. The Ioniq Hybrid and Plug-in Hybrid deliver a little more oomph, especially when you change the drive setting mode from Eco to Sport.

Hyundai gives you three settings for the regenerative braking system, so you can adjust how sharply the Ioniq slows when you release the throttle. On rough pavement, the Ioniq tends to bounce around, and it exhibits generally ponderous handling with little feedback from the road. You may need to make frequent adjustments to stay in your lane on the highway.

  • Base powertrain: 139-horsepower 1.6-liter four-cylinder and electric motor (hybrid)
  • Available powertrain:
    • 139-horsepower 1.6-liter four-cylinder and electric motor (plug-in hybrid)
    • 118-horsepower electric motor (electric)
  • Drivetrain: front-wheel drive
  • Transmission: six-speed dual-clutch automatic
Does the 2018 Hyundai Ioniq Get Good Gas Mileage?

Throughout its lineup, the Ioniq is one of the most fuel-efficient vehicles you can buy. Expect to spend around $700 or $750 annually for fuel with the regular hybrid version and as little as $500 per year to juice up the all-electric Ioniq.

  • Hybrid Blue: 57/59 mpg city/highway
  • Hybrid: 55/54 mpg
  • Plug-in Hybrid: 119 MPGe combined city/highway
  • Electric: 136 MPGe

2018 Hyundai Ioniq Alternative Fuels and Charging

The Ioniq Plug-in Hybrid has an all-electric range of 29 miles, and the Ioniq Electric has a range of 124 miles. The charging time depends on the method used:

  • Plug-in hybrid, 220-volt charging station: 2 hours and 18 minutes
  • Electric, 220-volt charging station: 4 hours and 25 minutes
  • Electric, Level 3 DC fast-charging: 23 minutes for 80% capacity

2018 Ioniq Interior

How Many People Does the 2018 Ioniq Seat?

The 2018 Ioniq seats five people in two rows. The back seat can feel a little cramped, especially for taller riders. There is also a bar that awkwardly splits the rear hatch window into two pieces, hampering rearward visibility.

Standard seating features:

  • cloth upholstery

Available seating features:

  • leather upholstery
  • power-adjustable driver's seat
  • driver's seat memory setting
  • heated front seats
  • leather-wrapped steering wheel and shift knob
How Many Car Seats Fit in the 2018 Hyundai Ioniq?

The 2018 Ioniq has two complete sets of LATCH car-seat connectors on the rear outboard seats and an upper tether on the rear middle seat. The Insurance Institute for Highway Safety gave the system the second-highest rating of Acceptable for ease of use. You may find that the lower anchors are set too deeply in the seat cushions, but that's about the only hiccup.

2018 Hyundai Ioniq Features

It doesn't take long to become a pro at using Hyundai's infotainment system. The interface is easy to navigate, with a nice array of redundant buttons and knobs for when you don't want to use the touch screen.
