Kaiyi X3 pro EV: which version to buy
If the question is which Kaiyi X3 pro EV to buy, the catalogue answer is narrower than the question. The model key is 3533. Brand in the data is Kaiyi. English name is X3 pro EV (imya_en_est true). The file lists 1 generation (pokoleniy: 1). That generation’s body label is SUV 5-doors. Production start is 2021-09-01. Production stop is null, so the generation is still open in this catalogue.
If the question is which Kaiyi X3 pro EV to buy, the catalogue answer is narrower than the question. The model key is 3533. Brand in the data is Kaiyi. English name is X3 pro EV (`imya_en_est` true). The file lists 1 generation (`pokoleniy`: 1). That generation’s body label is SUV 5-doors. Production start is 2021-09-01. Production stop is null, so the generation is still open in this catalogue. The generation record lists modifikaciy: 0 and versions: []. There is no named version such as «4.0 AT» or «3.3 AT» to rank. Horsepower, newton-metres, displacement, fuel, cylinders, layout, boost, gearbox, and drive are not measured for any row. Power per litre, weight per horsepower, and “what the extra money buys” cannot be calculated: there are no power figures, no weights, and no prices in the launch data. A buyer comparing trims is comparing an empty table to itself.
Which version to buy (Kaiyi X3 pro EV specs in the file)
“Which version” only works when at least two named versions exist. Here the count of versions is 0. Arithmetic on that count: 0 versions to pick, 0 pairs to compare, 0 extra horsepower from a higher trim, 0 extra newton-metres, 0 extra millilitres of displacement. Identical names distinguished by power (the Land Cruiser pattern of two «3.3 AT» rows at different hp) do not apply: there are no duplicate names because there are no names.
What the data does fix for a purchase decision:
- One generation key: 7620.
- Generation English name: 1 generation.
- Body: SUV 5-doors.
- Start: 2021-09-01.
- Stop: not measured (null).
- Version list: empty.
If a listing is sold as a Kaiyi X3 pro EV from this generation, this catalogue cannot tell you whether it is a higher-output row or a lower-output row. Those rows are not in `versions`. Choosing “the EV one” versus “the other one” is also not a comparison inside this file: the model name is X3 pro EV, and no second model key is supplied in the payload.
Generations: what 1 generation changed versus what it did not
There is 1 generation, not two. A generation-to-generation comparison therefore has one side only.
1 generation (key 7620) starts 2021-09-01. Stop is not measured. Body is SUV 5-doors. Version count is 0. Restyling is not listed as a separate generation and is not listed inside this generation either: the payload has no restyle flag, no restyle year, and no second body string. Treating a restyle as an 11th generation three times is the error this catalogue forbids; here the opposite error would be inventing a restyle. None is recorded.
What generation 7620 changed versus a predecessor is not measured: `generations` has a single object. There is no generation 0 in the array, so you cannot subtract start years, body counts, or version counts against an earlier Kaiyi X3 pro EV generation. Difference in generation count versus a two-generation model would be 1 − 2, but that other model is not in this payload; the only legal generation count here is 1.
What stayed the same for the whole open run, by construction of a one-row array: body SUV 5-doors, version count 0, English generation label 1 generation. If a dealer claims a “second generation” X3 pro EV under this model key 3533, that claim is outside this file.
Engine and specs: empty version table
Required columns: hp, Nm, displacement, fuel, cylinders, layout, boost, gearbox, drive. Required rule: version names exactly as in the base. The base has no version names.
| Version (exact name) | hp | Nm | Displacement | Fuel | Cylinders | Layout | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|---|
| (no named version in `versions`) | not measured | not measured | not measured | not measured | not measured | not measured | not measured | not measured | not measured |
Fuel must be taken from the English label in the data when a version exists. No version exists, so fuel is not measured, not guessed as gasoline, diesel, or electric even though the model string contains “EV”. Cylinders and layout must come from version rows; they are not measured. Gearbox and drive English labels (Automatic, AWD, and the like) are not measured. Boost is not measured. Displacement is not measured. Inventing a “petrol six” or a “V-format” is forbidden; the file does not supply cylinder count or bank layout.
Power per litre is hp divided by litres. With hp not measured and displacement not measured, power per litre is not measured. It is not zero. Zero would mean a measured engine with measured litres and measured hp of 0. Here the divisor and the dividend are both absent.
Performance and economy (0-100, top speed, mpg)
0–100 is not measured. Top speed is not measured. Fuel consumption / mpg is not measured. Combined, urban, and extra-urban figures are not measured. Electric consumption, range, battery kWh, and charge time are not measured. The model name X3 pro EV does not insert those numbers.
A ranking by 0–100 cannot be written: there are 0 timed versions. A ranking by mpg cannot be written: there are 0 consumption rows. Saying one trim uses less fuel than another would be a number that is not in the data. Saying the car is “efficient because it is EV” would be a claim without a measured kWh/100 km or mpg-equivalent.
If a brochure quotes 0–100 or mpg for a Kaiyi X3 pro EV, that brochure is not this dataset. In this dataset those figures are not measured.
Dimensions and weight
Kerb weight is not measured. Gross weight is not measured. Ground clearance is not measured. Tank volume is not measured. Wheel sizes are not measured. Length, width, height, and wheelbase are not measured.
Weight per horsepower is kerb weight divided by hp. Both are not measured, so kg/hp is not measured. You cannot say a heavier version “buys” more stability or that a lighter version “buys” better acceleration: neither weight nor hp is in the file.
Ground clearance cannot be used to pick an off-road-leaning SUV 5-doors over a street-leaning one: clearance is not measured. Wheel size cannot be used to pick a larger-wheel trim: wheel size is not measured. Tank size cannot be used to pick a longer-range trim: tank is not measured, and no battery capacity is given either.
The only body fact that is given for packaging is SUV 5-doors on generation 7620. Door count in that English label is five. No other body (sedan, wagon, coupe) appears in `body`. Choosing body type is therefore not a fork: the catalogue has 1 body string.
Reliability and problems
Reliability scores, common problems, recall counts, and warranty years are not measured. They are not omitted because “this car has no problems”; they are omitted because the launch object has no such fields. A paragraph that named typical faults would be a retelling of sources that are not in the data.
What a buyer can pin to the file: model X3 pro EV, brand Kaiyi, generation count 1, generation 1 generation from 2021-09-01 with stop not measured, body SUV 5-doors, versions 0. Any “known issues by year” list would need year-by-year version rows; those rows are empty.
What the extra money would buy (arithmetic on given numbers)
Prices are not in the data and must not be invented. “Extra money” as a currency amount is not measured. The only arithmetic the file allows is on counts that exist:
- Generations listed: 1. Extra generations you can buy into: 1 − 1 = 0.
- Bodies listed: 1 (SUV 5-doors). Extra bodies: 0.
- Named versions: 0. Extra versions a higher invoice could unlock inside this catalogue: 0.
- Restyles listed: 0. Extra restyle you could wait for inside this array: 0.
- Measured hp values: 0. Extra hp from stepping up a trim: not measured.
- Measured Nm values: 0. Extra Nm: not measured.
- Measured displacement values: 0. Extra litres: not measured.
- Measured 0–100 values: 0. Seconds saved: not measured.
- Measured mpg values: 0. Fuel saved: not measured.
- Measured kerb weights: 0. Kg saved or added: not measured.
So the honest purchase rule from this payload is not “buy the 150 hp row” or “buy the AWD row”. Those rows are not here. The rule is: if you need a named Kaiyi X3 pro EV version with hp, Nm, fuel, gearbox, and drive filled in, this catalogue page cannot recommend one, because modifikaciy is 0. If you only need the model and generation window, the file supports X3 pro EV, 1 generation, SUV 5-doors, on sale in this catalogue from 2021-09-01, stop not measured.
Which version to choose — verdict from the numbers given
Choose among versions only after versions exist. For Kaiyi X3 pro EV (model key 3533) they do not. Generation 7620 is the sole generation; it does not split into a pre-facelift and a facelift in this object. Body choice is SUV 5-doors or nothing else in the file. Engine choice, gearbox choice, and drive choice are not measured. Performance choice (0–100, top speed, mpg) is not measured. Weight and size choice (kerb, gross, clearance, tank, wheels) is not measured. Power per litre and weight per horsepower are not measured. Duplicate version names distinguished by hp do not occur.
Until `versions` contains exact names from the base, a comparison article cannot rank «4.0 AT» against «3.3 AT» or any other string, because those strings are not in this launch data. The catalogue’s buyer guidance for this model is therefore: there is 1 generation to be in, 0 versions to pick among, and every spec that would decide the pick is not measured.
