Which Li Auto L9 version to buy
There is no second row in the table to compare on horsepower, torque, or drive. The useful comparison is internal: how much power AT extracts from 1496 cm³, how much mass each horsepower must move, and how much payload sits between kerb and gross.
AT is the only modification in 1 generation (from 2022-07-01, still listed with no end date). Body is SUV 5-doors. Powertrain label is Plug-in. Output is 449 hp (330 kW) and 620 Nm from 1496 cm³, 4 cylinders, Inline, Turbo, Front, transverse. Gearbox is Automatic with 1 speed. Drive is AWD. Combined fuel figure is 7.1. Kerb weight is 2520 kg, gross 3120 kg, ground clearance 180 mm. 0–100 is 5.3 s; top speed is 172.
There is no second row in the table to compare on horsepower, torque, or drive. The useful comparison is internal: how much power AT extracts from 1496 cm³, how much mass each horsepower must move, and how much payload sits between kerb and gross.
- Power per litre: 449 ÷ (1496 / 1000) = 300.1 hp per litre.
- Torque per litre: 620 ÷ 1.496 = 414.4 Nm per litre.
- Kerb mass per horsepower: 2520 ÷ 449 = 5.61 kg per hp.
- Gross mass per horsepower: 3120 ÷ 449 = 6.95 kg per hp.
- Horsepower per tonne (kerb): 449 ÷ 2.520 = 178.2 hp per tonne.
- Payload (gross minus kerb): 3120 − 2520 = 600 kg.
- Payload as a share of kerb: 600 ÷ 2520 = 23.8%.
- Clearance-to-kerb: 180 mm under 2520 kg.
If those ratios are what you wanted from a large SUV 5-doors with AWD, you are already looking at the version that exists. There is no “lesser AT” and no “AT with more speeds” in this dataset.
Li Auto L9 generations: what changed (and what did not)
1 generation is the whole story. Start: 2022-07-01. Stop: not measured (listed as current). Body: SUV 5-doors. Modifications in this generation: 1 (AT). No restyling is recorded as a separate generation, so there is no “1 generation restyle” to treat as an 11th-generation duplicate. Years, body, and version count do not fork.
What a second generation would usually change — extra body types, extra gearboxes, a second displacement — is not in the data, because a second generation is not in the data. Buying “the later L9” versus “the early L9” is not a catalogue choice here: production of 1 generation has no stop date in the source, and AT itself starts 2022-07-01 with stop not measured.
So generation comparison collapses to: you either take 1 generation AT, or you leave the model. There is no arithmetic between generations because there is only one generation’s numbers.
Engine and specs: the only row is AT
People search “L9 engine”, “L9 specs”, “L9 horsepower”. All of those queries hit one version name, written exactly as in the base: AT.
| Version | hp | kW | Nm | Displacement (cm³) | Fuel | Cylinders | Layout | Boost | Engine position | Gearbox | Speeds | Drive | Engine type |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| AT | 449 | 330 | 620 | 1496 | 95 | 4 | Inline | Turbo | Front, transverse | Automatic | 1 | AWD | Plug-in |
rpm for peak power: not measured. rpm for peak torque: not measured. Valves per cylinder: 4. Compression ratio: not measured. Bore and stroke: not measured. Fuel system: not measured.
What the extra money would buy on a typical multi-version SUV — a second displacement, a second cylinder count, a second drive — is not on offer. AT is already the high-output row: 449 hp from 1496 cm³ with Turbo and Plug-in. The 1-speed Automatic is not a trim choice either; it is the only gearbox listed.
If two versions had shared the name AT, they would be split by horsepower. They do not. One name, one output: AT 449 hp.
Performance: 0–100, top speed, and what the mass does to them
AT 0–100: 5.3 s. Top speed: 172. Those two figures belong to AT only.
With 2520 kg kerb, 5.3 s means the 449 hp and 620 Nm are doing the work against 5.61 kg per hp. Load the car toward 3120 kg and each horsepower is responsible for 6.95 kg instead of 5.61 kg — a 23.8% rise in mass per horsepower, equal to the 600 kg payload. The source does not re-measure 0–100 at gross weight; that 5.3 s is the listed figure, not a second test.
172 top speed next to 449 hp is a limiter, not a shortage of listed power. The catalogue does not give a second AT with a higher top speed, so you cannot buy “the fast L9” as a different modification. You buy AT and you get 172.
City consumption: not measured. Highway consumption: not measured. Combined: 7.1 for AT. CO2: not measured. Eco class: not measured. Tank size: not measured. Wheel sizes: not measured.
mpg and fuel: what is measured on AT
Search traffic for “L9 mpg” and “L9 fuel consumption” has one number to land on: combined 7.1 for AT, fuel type 95, engine type Plug-in.
Do not treat city or highway as zero: they are not measured. Combined 7.1 cannot be split into city and highway from this dataset. Tank is not measured, so range is not a number you can form from these fields without inventing a tank. Anyone choosing AT for touring has 7.1 combined and 95, and no tank figure.
Because there is only one version, there is no “thirstier AT” versus “leaner AT”. The economy choice is whether 7.1 combined on 95 is acceptable. It is not a trim ladder.
Dimensions, weight, and clearance: AT as a 2520 kg SUV 5-doors
Kerb: 2520 kg. Gross: 3120 kg. Ground clearance: 180 mm. Tank: not measured. Wheels: not measured.
Front suspension: Independent, spring. Rear suspension: Independent, spring. Front brakes: Ventilated disc. Rear brakes: Disc ventilated.
Payload is 600 kg. That is the only “size of version” difference you can compute, because there is no second kerb weight. 180 mm clearance under 2520 kg is the stance of this SUV 5-doors; there is no high-clearance AT and no low AT.
Weight versus power is the buying lever that would normally separate versions. Here it is fixed:
- 2520 kg / 449 hp = 5.61 kg/hp
- 600 kg payload / 449 hp = 1.34 kg of payload per hp
- 180 mm clearance is the listed figure; a second clearance is not listed
If 2520 kg kerb is too heavy for the use case, this model does not sell a lighter L9. If 180 mm is too low, it does not sell a taller L9. Those are not trim options; they are the AT numbers.
Problems, reliability, and what this catalogue does not measure
“L9 problems” and “L9 reliability” are real search phrases. This source does not list failure rates, recall counts, or service intervals. Those values are not measured here. Do not read silence as “no problems”; read it as “not in this dataset”.
What is measured and relevant to durability shopping: Ventilated disc front, Disc ventilated rear, Independent, spring at both ends, AWD, Automatic with 1 speed, Turbo Plug-in 4 Inline at Front, transverse. rpm limits are not measured. Eco class is not measured. CO2 is not measured.
A buyer comparing two L9s in the real world is comparing condition and equipment, not two catalogue versions. The catalogue has one mechanical identity: AT.
Which version to choose: the arithmetic, not the brochure
There is nothing to split on body (only SUV 5-doors), generation count (only 1 generation), version count (only 1), drive (only AWD), or gearbox (only Automatic, 1 speed).
Choose AT when all of the following are acceptable at once:
1. 449 hp and 620 Nm from 1496 cm³ (300.1 hp/l, 414.4 Nm/l), Turbo, Plug-in, 4 Inline, Front, transverse. 2. 5.3 s to 100 and 172 top speed — not a second, quicker row. 3. Combined 7.1 on 95, with city, highway, tank, CO2, and eco class not measured. 4. 2520 kg kerb, 3120 kg gross, 600 kg payload, 180 mm clearance, wheels not measured. 5. Production from 2022-07-01 with stop not measured.
Do not choose this model if you need a second L9 with fewer hp, a different cylinder layout, a second displacement, or a second drive. Those versions are not in the data. The “extra money” in a multi-version range usually buys more hp, more Nm, or a different gearbox. On Li Auto L9, extra money cannot buy a second catalogue version because AT is the only named modification.
If two cars on a lot are both L9 AT, they are the same version in this base: same 449 hp, same 620 Nm, same 1496 cm³, same AWD, same Automatic 1, same 5.3 s, same 172, same 7.1 combined, same 2520 / 3120 / 180. Distinguish them by condition and options outside this table, not by renaming AT.
Bottom line: buy AT as the Li Auto L9, or do not buy this model. The numbers that justify AT are 449 hp from 1496 cm³, 5.61 kg per hp at kerb, 600 kg payload, 5.3 s, 172, 7.1 combined, AWD, SUV 5-doors, 1 generation from 2022-07-01. Everything else a shopper usually uses to pick between versions is not measured or does not exist as a second row.
