True Motion Auto's ranking guides score cars across six weighted categories: safety, reliability reputation, running costs, practicality, value-for-money and driving experience, combining independent test data (crash ratings, official efficiency figures) with attributed range-based estimates for costs that vary by region. No single category can outweigh a serious safety or reliability shortfall — those act as a check on the overall score rather than being purely additive.
At a glance
| Scorecard category | Approximate weighting |
|---|---|
| Safety | 25% |
| Reliability reputation | 20% |
| Running costs | 20% |
| Practicality | 15% |
| Value-for-money | 10% |
| Driving experience | 10% |
Why we publish the methodology openly
A ranking is only useful if readers can trust how it was built. Rather than presenting a list of "best" cars as if it were an objective, unarguable fact, we publish the criteria and approximate weighting behind every ranking guide so readers can judge for themselves whether our priorities match their own — and adjust their own thinking if, say, driving enjoyment matters far more to them than it does to our default weighting.
The six scoring categories
- Safety — drawn from independent test bodies (Euro NCAP, Global NCAP, NHTSA/IIHS) for the specific tested variant, checked for test-year and protocol version.
- Reliability reputation — based on patterns across multiple independent owner-satisfaction and dependability studies, not single-source claims or manufacturer marketing.
- Running costs — combines official fuel/energy efficiency figures with attributed ranges for insurance, servicing and depreciation, since exact figures vary by region and individual circumstances.
- Practicality — cabin and boot space, seating flexibility, and everyday usability for the vehicle's stated purpose (family, city, towing, etc.).
- Value-for-money — how much car, feature-for-feature, a given price delivers relative to close segment rivals, not simply the lowest price.
- Driving experience — ride comfort, refinement and handling character, judged against what buyers in that specific segment typically want (e.g. comfort for a family SUV, engagement for a hot hatch).
How categories are weighted, and why
Safety and reliability reputation carry the heaviest weighting because they affect nearly every buyer regardless of what they value most, while driving experience is weighted lightly since it's the most subjective category and matters far more in some segments (sports cars) than others (family MPVs). Weightings can shift slightly for segment-specific guides — for example, a towing-focused ranking weights practicality and capability more heavily than a city-car ranking would.
What we deliberately don't do
| We avoid | Because |
|---|---|
| Inventing precise scores from thin data | A confident-looking number built on guesswork is worse than an honest range |
| Letting one strong category fully offset a serious safety or reliability weakness | Those two factors act as a floor/check on the overall ranking, not just additive points |
| Treating manufacturer-claimed figures as verified fact | Official efficiency/range figures are noted as such, with real-world caveats where relevant |
| Publishing a ranking without a visible "last reviewed" date | Rankings age — pricing, model-year changes and test updates need periodic review |
How to use our rankings alongside your own priorities
- Read the specific category scores, not just the overall rank, if one factor (say, safety or running cost) matters far more to you than others.
- Check the "last updated" date on any ranking guide before relying on pricing or model-year-specific claims.
- Treat rankings as a shortlist starting point, not a final verdict — always confirm current local pricing, trim availability and a test drive before buying.
- Cross-check safety and reliability claims against the original independent source we cite, especially for a purchase decision.
No ranking can fully replace a test drive and your own priorities — use our scorecard as a structured starting point, not a final answer.
