Hey everyone, looking for some technical feedback. I have a 2026 CR-V Hybrid (AWD) I used to get a good efficiency even in peak winter but now in warmer weather, the "Hybrid math" just isn't mathing.
I’m a data person, so I’ve been tracking the telemetry closely. I’m seeing a negative range-to-odometer correlation that makes no sense for a hybrid:
- The Test Case: Drove 122 km in a mix of slow traffic and highway with AC or heat off completely.
- The Result: The Range meter dropped by 125 km.
- Conditions: 15°C (60°F) outside, light throttle, and the dash showed "EV" active for roughly 60% of the drive.
Previously when I was using the same car under 0°C weather in winter, I drive 140 km on the same mix of slow traffic and highway where the range drops only 110 km. In the recent trips I started seeing this. In a functioning hybrid, 122 km of distance in traffic should only "cost" about 90–100 km of range because the battery is supposed to carry the load. Instead, I’m actually losing more range than distance traveled.
My lifetime average is stuck at 6.5L/100km, and it refuses to budge even with hypermiling. I suspect a sensor offset (Active Grille Shutter or Thermal Sensor) is forcing the engine into a constant "warm-up loop" or parasitic load in the background.
Has anyone else dealt with range dropping faster than the odometer? I’m taking it to the dealer for a system scan, but I want to know if I'm crazy or if there's a known calibration bug here.
