MYCAR SCORE™ METHODOLOGY
Exactly how we rate vehicles, where the data comes from, how complete that data is, and what the number can and cannot tell you.
What Is the MyCar Score™?
The MyCar Score™ is a proprietary 45 to 95 rating that combines federal safety data, fuel efficiency, performance, and value into a single number for every vehicle we have rated. It gives used car buyers a fast, data-driven way to compare vehicles across makes, models, and years within the same class.
The score is calculated independently by mycarneedsthis.com. It is not influenced by manufacturer relationships, advertising, or affiliate partnerships. When the underlying data changes, such as a new NHTSA rating or an updated recall count, scores are recalculated automatically.
How We Score, Step by Step
- For each vehicle class, we compute the median MPG, MSRP, and power-to-weight ratio. These medians are the yardstick every vehicle is measured against, so the score is relative to class peers rather than absolute.
- We score four components against those class medians: safety (25 points), fuel efficiency (15 points), power-to-weight (15 points), and value (15 points), for a raw total out of 70.
- The raw total is normalized onto a 50 to 95 scale, then reliability adjustments for recalls and complaints are subtracted.
- The result is clamped to a 45 to 95 range and rounded to one decimal.
A small share of vehicles carry editorial sub-scores (driving, comfort, interior, technology, utility). Where at least three of those are present, they replace the spec-based components above. Most vehicles use the spec-based method described here.
Component Weights
The spec-based score combines four weighted factors. Safety carries the most weight because crash outcomes matter most; fuel economy, performance, and value each contribute meaningfully to a rounded view of the vehicle.
Safety (NHTSA Stars)
Safety: ~36%Overall star rating from NHTSA crash testing, sourced directly from the National Highway Traffic Safety Administration. Star ratings exist for only a minority of configurations (see Data Coverage below); when a rating is unavailable, safety is scored at the class-neutral midpoint so a missing rating neither raises nor lowers the score.
Fuel Efficiency (EPA MPG)
Fuel: ~21%Combined MPG compared to the median for the vehicle's class. More efficient vehicles score higher. Electric vehicles use a 110 MPGe equivalent when standard MPG is not published, so they compare fairly against combustion vehicles. Data comes from the EPA.
Performance (Power-to-Weight)
Performance: ~21%Horsepower relative to curb weight, compared to the class median. This measures usable acceleration rather than raw horsepower alone.
Value (MSRP vs Class)
Value: ~21%Base MSRP compared to the class median. Vehicles that offer more capability per dollar score higher. This measures new-vehicle value, which correlates with used-vehicle value retention.
Reliability Adjustments
After the weighted components are combined, the score is adjusted down based on real-world reliability signals from NHTSA:
Recall Adjustment
Each NHTSA recall reduces the score by half a point, capped at a five-point reduction. This is a count of open and past recall campaigns, not a severity measure.
Complaint Adjustment
NHTSA consumer complaint volume reduces the score by half a point per fifty complaints, capped at a four-point reduction. This is a raw count of owner-filed reports, not a per-vehicle rate (see Why We Do Not Publish Complaint Rates below).
Data Coverage and Sparsity
A rating is only as trustworthy as the data behind it, so here is exactly how complete our inputs are. When any single input is missing for a vehicle, that component is scored at the class-neutral midpoint. A missing input therefore neither inflates nor deflates the score; it simply drops out, and the score reflects only the data we actually hold.

The one input to know about: crash-test stars
NHTSA physically crash-tests only a subset of configurations, so real star ratings exist for roughly five percent of the vehicles we score. For the rest, the safety component uses the class-neutral midpoint rather than a real star rating. We show a real NHTSA rating on a vehicle only when NHTSA published one for that exact configuration; where we do not, we say so on the page rather than implying a rating exists.
Why We Do Not Publish Complaint Rates
We report recall and complaint counts, and we use them as small score adjustments, but we do not publish a complaints-per-vehicle rate or a reliability rate. An honest rate needs a denominator: the number of that model sold or on the road. A model with more complaints is often just a model with more vehicles in service, not a less reliable one.
We do not have a per-model, per-year sales or registration figure that we can stand behind, so any per-100,000 rate we published would be built on a number we cannot verify. Until we have a denominator we trust, we present counts as counts and label them plainly, rather than dress them up as rates they are not.
Editorial Process
Ratings are calculated from verified federal safety data, federal fuel economy data, and manufacturer specifications. The source for a given data point is cited on the vehicle and guide pages where the claim is made.
Editorial guides on this site are researched and drafted with AI assistance and reviewed by the MyCarNeedsThis editorial team before publication. Scores are recalculated automatically when underlying data is updated.
How to Read the Score
Higher scores indicate above-average safety, efficiency, and value relative to class peers, after reliability adjustments. Compare scores within the same vehicle class for the most useful read, since class medians anchor several of the components above. A two-point gap is noise; a ten-point gap is meaningful.
What the Score Does Not Cover
The MyCar Score™ is a starting point, not a final verdict. It does not account for:
- Individual vehicle condition (mileage, maintenance history, accident history)
- Regional pricing differences or current market conditions
- Subjective factors like ride quality, interior comfort, or brand preference
- Insurance costs, which vary by driver profile and location
- Aftermarket modifications or dealer add-ons
- Long-term reliability beyond recall and complaint counts (we do not have per-vehicle failure rates)
Always combine the MyCar Score™ with a pre-purchase inspection, a vehicle history report, and your own test drive before making a purchase decision.
Version History
v1.4 (March 2026)
Widened the score distribution across the full 45 to 95 range, reduced the recall penalty, and added an EV MPGe equivalent for fair fuel-economy comparison. Recall and complaint counts were backfilled for nearly all combos. Crash-test star ratings remain available only for the subset NHTSA has physically tested; the safety component uses a neutral midpoint elsewhere.
v1.3 (February 2026)
Initial scored release with the spec-based formula and partial NHTSA data, validated against third-party editorial ratings.
