How does WhichTrim decide which vehicle wins?
Each of seven categories — price, fuel and range, safety, space and cargo, performance, tech and comfort, warranty — is scored 0–100 from the data on the page. Relative measures give 100 to the better vehicle and a proportional share to the other; NHTSA stars and the Safety Signal use their own scales. The overall score is the weighted mean at the default weights (price 4, safety 4, fuel 3, tech 3, space 2, performance 2, warranty 2). A margin of 6 points or more is a clear win, 2 to 6 an edge, under 2 a toss-up. Every pair page has sliders to set your own weights.
