I'm only managing 37 mpg on my brand-new 2025 Corolla Hybrid.!

Just picked up a new 2025 Corolla Hybrid AWD LE. I was excited about getting 40+ mpg, but so far, I’m only averaging 37 mpg, even while driving extremely cautiously.

I accelerate slowly (probably annoying other drivers), coast frequently, and brake gently. I try to maintain a consistent speed as much as possible. About 80% of my commute is highway driving at 70-80 mph. I’ve experimented with cruise control, but it doesn’t seem to make a difference—sometimes it even revs more. I’ve also tried driving in and out of Eco mode, but my mpg remains the same. Meanwhile, I keep seeing others report getting over 50 mpg.

I’m in Michigan, and my car has around 1,500 miles on it. Could something be wrong with my vehicle, or is this normal?
