Notes and sources

  1. Fuel economy: not published. A fuel-economy figure was published for this car (35.0 mpg) and is withheld here: it is not comparable with the other cars in this list.↩
  2. CO₂: EPA's charge-weighted composite — the miles it assumes are driven on grid electricity are credited at zero tailpipe — 151 g/mi, or 94 g/km. It is lower than the tailpipe rating a petrol car states, and it is not what the car emits with the battery empty.↩
  3. Fuel cost: not estimated. A plug-in hybrid's fuel use depends on how much of its driving is done on the battery, so no cost is computed for it.↩
  4. Power: 137 hp is the combustion engine's rating alone, from EPA test-car data; the basis is confirmed by NHTSA's vPIC engine record. The whole car's output with the electric motor is not published by any free source, so it is not stated.↩
  5. Crash rating: not published. NHTSA lists this car (15633) and publishes no overall rating for it: it rates a car overall only when it has run the frontal, side and rollover tests on it.↩
  6. Recall campaigns: NHTSA's count for this nameplate (CROSSTREK HYBRID), as of 2026-09-10. Each is repaired free of charge by dealers.↩
  7. Complaints: NHTSA holds 4 for the 2021 Crosstrek, 0 of which describe a crash, fire, injury or death. The rate per 10,000 built is not computed: complaints no VIN places, or production no fuel code places, make the rate uncertain by more than 5%.↩
  8. Kerb weight: not published. No source states a curb weight for this car.↩
  9. EPA test weight: 4,000 lb (1,814 kg) is the equivalent test weight class EPA tested this configuration at, not the kerb weight.↩
  10. Warranty: 3 years or 36,000 miles, from Subaru's published 2021 warranty statement, compiled into carstandings.com's warranty table.↩
  11. Registrations: 141 Crosstreks of this model year on New York's roads, from the NY DMV registration file as of 2026-09-02.↩
  12. This car is measured on the plug-in scale: miles per gallon on fuel, a charge-weighted CO₂ rating that credits its electric miles, and engine horsepower. MPGe and the plain tailpipe rating do not apply to it.↩
  13. Price: no free, resellable source publishes a price for any 2021 car sold in the United States, so none is shown for any car in this market.↩
