What am I doing wrong with MPG?

I have a 2025 Hybrid Calligraphy with 1600 miles. It had 500 miles when I bought it because of a dealer trade. It’s on ECO mode. Of the 1100 miles, 40% is on country roads, 40% on interstate (at 75 mph), and 20% in town.

I have a Limited FWD and I get about 40-42 MPG. Here’s how I drive:

  1. Mostly city driving, speeds between 40 to 65 MPH.
  2. I avoid hard acceleration—just take it slow and only press it hard when I need to pass.
  3. I try to coast as much as possible and avoid hard braking. I keep a safe distance from other cars—around 2 to 3 car lengths.
  4. I tried Regen braking, but it didn’t boost my mileage much. Coasting seems to give me better results.
  5. I’ve managed to get almost 700 miles on a full tank.
    I’m at 1500 miles, and I’ll have a better idea of my mileage when I hit 3000 miles.

That’s what I get with my non-hybrid model. Like others have said, ease into acceleration and avoid sudden starts. You also need to set the regen braking to max for better mileage.

I can’t get anywhere near the MPG either. I have a Prius that easily gets good mileage, but the Santa Fe drops to 25-28 MPG on the highway, even though it gets 35-40 MPG in the city.

Try turning on regen braking. Ease off the gas pedal and avoid heavy acceleration.

Level 1 regen is fine, but Level 2 and 3 can annoy people behind you because the brake lights stay on.

Haha, I had the same thought when I first drove a hybrid. I used to wonder why people were braking so much!

How do I turn on regen braking? I know about easing off the gas, but I’m not sure how to use regen braking.

It’s in your owner’s manual. The left paddle increases regen levels, and the right paddle decreases it. Hold the right paddle for a few seconds to activate Auto regen, which adjusts the braking based on traffic ahead. I’d suggest reading the manual for a full explanation—it’s a high-tech car!

Thanks! I didn’t realize the paddles were for regen. I usually just Google things I don’t understand, but I’ll check the manual now.

The paddles adjust regen in Eco mode, but in Sport mode, they shift gears. I don’t know about the other modes, though.

Got it. I mostly use Eco mode, but I switch to Sport mode sometimes when I need to drive more aggressively. People drive wild here in Phoenix!

You need to adjust how you drive for better mileage. Keep the power meter in the Eco or Charge zones as much as you can. Accelerate slower and brake earlier. Use regenerative braking because hard braking wastes energy. If you’re going downhill, try to stay in EV mode as much as possible to save gas. I can often get up to 40-45 mph without the gas engine coming on.

Isn’t regen braking on by default? I thought it was automatically set to Auto mode.

Hold the right paddle for three seconds to activate Auto regen. It adjusts based on your speed and the distance ahead.

Yes, regen works when you brake, but once the charge meter is full, the car can’t regenerate any more energy.

Nope. Check your manual for the details.

I have a 2024 Calligraphy Hybrid with almost 18,000 miles. My average is 27.4 MPG, but I’ve never been able to get close to the claimed numbers, so I just gave up on trying.

I get about 29 MPG, mostly highway. The 34 MPG claim from Hyundai seems exaggerated, and it’s a bit disappointing.

I have a 2024 SEL Hybrid with 3k miles and get around 31.4 MPG. I mostly drive on the freeway, but I try to be gentle on the accelerator to maximize EV mode. Do you think the nicer wheels could be affecting your MPG?
