How Voltranker scores a car
Published in full, applied identically to every vehicle, and versioned so any past ranking can still be audited against the rules in force at the time.
The 8 pillars
Nobody types a pillar score or a final score. Editors enter measured raw data — warranty length, ground clearance, service-centre count, price, real-world range, and the rest. Absolute pillars are derived from that data against the published threshold tables below. Value is scored relative to the other cars in the same price tier. The composite is the weighted sum of the pillars.
Weights are the same for every car in every tier. Ranking happens within a tier only.

What each pillar measures
Value
Weight 22%
Ex-factory and estimated on-road price against what the car delivers in range, features, equipment and warranty, measured within the tier. A cheap car is not automatically good value, and an expensive one is not automatically bad. Similarly, an expensive car is not automatically the best value and a cheaper version is not automatically worse.
Reliability
Weight 22%
Vehicle and battery warranty terms as published for Pakistan. Longer transferable cover scores higher against the threshold table.
Performance
Weight 18%
Real-world range, DC charging rate and battery capacity — the usable energy and recharge ability of the car, scored against fixed thresholds.
After-Sales
Weight 12%
Official service-centre count and whether there is an authorised Pakistan dealer network. Coverage outside the major cities is what the input is meant to capture.
Company Trust
Weight 12%
How long the brand has operated in Pakistan and whether it maintains an official dealer presence. Commitment length is the measured input.
Charging Network Compatibility
Weight 5%
Maximum DC charge rate (and connector data where recorded) against the public network that exists here. Faster compatible DC acceptance scores higher.
Pakistan Road Suitability
Weight 5%
Ground clearance in millimetres against fixed thresholds written for Pakistani road surfaces.
Market Sentiment
Weight 4%
Owner survey score where a sample exists. Weighted lowest among the pillars because sentiment is the softest evidence we hold.
Threshold tables
Every absolute pillar score is produced by reading one measured input and matching it to the first band that fits, top to bottom. Band scores are authored on a 1–10 scale and stored as 0–100. Value has no bands — it is relative within the price tier.
If a required input is missing, that pillar does not score. A car with any unscored pillar is excluded from rankings rather than ranked on a partial composite. The composite is the weighted sum of the 8 pillar scores using the weights above.
Value
22% of composite · relative within tier
No fixed bands. Each car’s cost per kilometre of real-world range (ex-factory price ÷ range) is ranked against every other scored car in the same tier. Best in tier scores 100; worst scores 10; linear between. A tier with fewer than two priced cars cannot score Value.

Composite = Σ (pillar score × weight) ÷ 100. There is no field anywhere that can override that arithmetic.
Rules that constrain us
-
No manual adjustment
Pillar scores and the composite are derived on save. No editor, and no administrator, can type either.
-
No cross-tier ranking
Cars are ranked within tier only. Rank is stored as position inside a tier — there is no site-wide leaderboard field.
-
Ties share a rank
Equal composites in the same tier share a position and are labelled Joint #N. The next car takes the next free place (standard competition ranking).
-
Incomplete means unranked
If any pillar is unscored, the car is excluded from rankings entirely rather than ranked on a partial score.
-
Every pillar shows its working
Each car page can open the measured input and the threshold band that produced that pillar. A challenge is reviewed against those same figures.
-
Every change is logged
Old value, new value, who changed it, when, and under which methodology version. The log is append-only.
-
Commercial is separate
Verified status lives on the company record and is unreadable by any scoring function.
Two-wheelers
How bikes and scooties will be scored
Two-wheeler methodology v0.9. Published in full before a single bike is scored, so the rules cannot be accused of having been written to fit a result.
No bike carries a score yet
The weights below are reasoned from market structure, not yet from evidence of what two-wheeler buyers actually trade off. Until eight validation interviews are complete they stay a draft, and every bike on this site is listed without a score. Publishing a number whose derivation we cannot defend would be the same defect as adjusting a score by hand.
This is not the car methodology
A two-wheeler buyer in Pakistan is rarely choosing between two electric bikes — they are deciding whether to leave a 70cc petrol motorcycle at all. That makes cost against a petrol baseline the first question rather than value against peers, so the pillars, the weights and the version number are all separate. A car score and a bike score are not comparable, and a revision to one does not touch the other.
Six pillars
| Pillar | Weight | What it answers |
|---|---|---|
| Total Cost of Ownership | 28% | Over five years, does this bike cost less than the petrol bike it replaces? |
| Battery & Energy System | 22% | Will the pack last, can it be charged where the owner lives, what does it cost to replace? |
| Reliability & Durability | 18% | Does it survive heat, water, broken roads and daily load? |
| After-Sales & Parts | 16% | When it breaks, how fast and where does it get fixed? |
| Real-World Usability | 10% | Does it do the job the owner bought it for, loaded, in traffic? |
| Company Trust | 6% | Will the manufacturer still exist when the warranty is claimed? |
Threshold tables
Every score is derived from raw data through these tables. No pillar score is ever typed in, and only Total Cost of Ownership is scored relative to a price tier — everything else uses fixed thresholds, so a bike's reliability score cannot change because a competitor launched.
Battery chemistry
40% of the Battery & Energy pillar.
| Chemistry | Points |
|---|---|
| LFP (LiFePO₄) | 100 |
| Li-ion / NMC | 85 |
| Graphene-lead | 45 |
| Lead-acid / gel | 20 |
| Unknown or not published | Not scored |
Payback against a 70cc petrol bike
40% of the Total Cost of Ownership pillar. Absolute thresholds, independent of peers.
| Payback period | Points |
|---|---|
| 12 months or less | 100 |
| 13 to 18 months | 85 |
| 19 to 24 months | 70 |
| 25 to 36 months | 50 |
| 37 to 48 months | 25 |
| Over 48 months, or never | 0 |
Battery warranty
25% of the Battery & Energy pillar.
| Warranty | Points |
|---|---|
| 36 months or more | 100 |
| 24 to 35 months | 80 |
| 12 to 23 months | 50 |
| Under 12 months | 20 |
| None or not published | 0 |
Removability and carryability
20% of the Battery & Energy pillar. Weight decides whether a removable pack is actually carryable.
| Pack | Points |
|---|---|
| Removable, 15 kg or less | 100 |
| Removable, 15 to 25 kg | 70 |
| Removable, over 25 kg | 45 |
| Fixed pack | 30 |
Charge time to full
10% of the Battery & Energy pillar.
| Charge time | Points |
|---|---|
| 3 hours or less | 100 |
| 3 to 5 hours | 75 |
| 5 to 8 hours | 45 |
| Over 8 hours | 15 |
The completeness gate
A bike is scored only when its data is at least 85% complete and its chemistry, battery replacement cost, price and battery warranty are all verified. Anything short of that is published as "Listed, not scored", naming the field we are missing. Expect most models to sit there at first. That is the correct outcome: a visible gap is recoverable, a wrong score is not.
Where a sub-metric cannot be scored under a published rule, its weight is redistributed across the remaining sub-metrics in that pillar only, never between pillars, and the profile page says so. The same rule is applied to every bike.
Battery swapping, and what would change its weight
Public swapping in Pakistan is a pilot, largely in one city. Scoring a national ranking heavily on a network most buyers cannot reach would transfer part of the verdict to whichever manufacturer is paired with that pilot, so swap compatibility carries 5% of the Battery & Energy pillar — 1.1% of the total score.
It rises to 20% of that pillar when verified public swap cabinets reach 100 or more, operating across at least three cities in at least two provinces. The trigger, the source and the date it was met are all published, and it cannot be met by one manufacturer's private network alone — that would make the score a measure of one company's capital spending.
Delivery riders get a filter, not a second score
Delivery riders weigh payload, uptime and cycle life far above purchase price. The obvious answer would be a re-weighted delivery score, and we are not building it: the moment two numbers exist for one bike, which one gets shown becomes an editorial lever, and an editorial lever is what a paying manufacturer eventually asks to pull. Instead there is a filter on published hard criteria, applied mechanically, with vehicles keeping their normal order inside it.
- Payload capacity of 150 kg or more
- Rear rack or box mounting point, fitted or available from the manufacturer
- Battery warranty of 36 months or more
- LFP or Li-ion chemistry only
- Battery replacement lead time of 21 days or less
Specifications on a listed bike can be disputed the same way a score can: write in and we answer within 14 business days, and any correction is logged in public.
