Geely MR: which version to buy — 1.3 AT vs 1.5 AT
If you are choosing a Geely MR, the catalogue gives two automatic sedans from the same 1 generation (2003-01-01 to 2009-12-31): 1.3 AT and 1.5 AT. Both are Gasoline, 4 Inline, Front, transverse, No boost, Distributed injection (multi-point), 5 Automatic, FWD, ground clearance 145. The buy decision is not “which generation”: there is one generation and two versions.
If you are choosing a Geely MR, the catalogue gives two automatic sedans from the same 1 generation (2003-01-01 to 2009-12-31): 1.3 AT and 1.5 AT. Both are Gasoline, 4 Inline, Front, transverse, No boost, Distributed injection (multi-point), 5 Automatic, FWD, ground clearance 145. The buy decision is not “which generation”: there is one generation and two versions. The extra 156 cm³ on 1.5 AT buys +8 hp and +18 Nm, with peak torque 1 800 rpm earlier. Acceleration, top speed, mpg, kerb weight, and tank size are not measured on either version, so they cannot break the tie.
Specs that actually differ between Geely MR versions
| Version | hp | kW | Nm @ rpm | Displacement | Fuel | Cylinders / layout | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|---|
| 1.3 AT | 86 @ 6000 | 63 | 110 @ 5200 | 1342 | 92 | 4 Inline | No | 5 Automatic | FWD |
| 1.5 AT | 94 @ 6000 | 69 | 128 @ 3400 | 1498 | 92 | 4 Inline | No | 5 Automatic | FWD |
Both versions share the same production window (2003-01-01–2009-12-31) and the same Sedan body. 1.5 AT is the only version with a measured emissions class: Euro 2. On 1.3 AT that class is not measured.
Which generation changed what
There is 1 generation of Geely MR. Restyling is not listed as a separate generation. Both 1.3 AT and 1.5 AT sit inside 1 generation, 2 versions, Sedan, 2003–2009. Nothing in the data shows a later generation that added power, drive types, or a different gearbox family. You are not choosing a year-facelift package with a new engine map; you are choosing displacement and the torque curve that comes with it.
Engine: what the extra 156 cm³ buys
1.3 AT is 1342 cm³, 86 hp (63 kW) at 6000 rpm, 110 Nm at 5200 rpm, compression 9.3, bore and stroke 78.7 × 69, 4 valves per cylinder. 1.5 AT is 1498 cm³, 94 hp (69 kW) at 6000 rpm, 128 Nm at 3400 rpm, compression 9.8; valves per cylinder not measured; bore and stroke not measured.
Arithmetic on those figures:
- Displacement: 1.5 AT is 156 cm³ larger than 1.3 AT (1498 − 1342), about 11.6% more volume (156 / 1342).
- Peak power: 1.5 AT has 8 hp more (94 − 86) and 6 kW more (69 − 63). That is about 9.3% more horsepower (8 / 86) for 11.6% more displacement.
- Specific power: 1.3 AT makes 86 / 1.342 ≈ 64.1 hp per litre (63 / 1.342 ≈ 46.9 kW per litre). 1.5 AT makes 94 / 1.498 ≈ 62.8 hp per litre (69 / 1.498 ≈ 46.1 kW per litre). The smaller engine is the denser one on paper; the larger engine does not extract more power per litre — it extracts more absolute power from more volume.
- Torque: 1.5 AT has 18 Nm more (128 − 110), about 16.4% (18 / 110). Specific torque: 1.3 AT 110 / 1.342 ≈ 81.97 Nm per litre; 1.5 AT 128 / 1.498 ≈ 85.45 Nm per litre. Here the larger engine is denser: about 3.5 Nm per litre more.
- Torque rpm: 1.5 AT peaks at 3400 rpm, 1.3 AT at 5200 rpm — 1 800 rpm earlier. Both still make peak power at 6000 rpm. For an Automatic 5 FWD sedan, the earlier torque peak is the largest driving difference in the table: 1.5 AT is specified to put its extra 18 Nm into the mid range, while 1.3 AT puts 110 Nm high in the rev range.
- Compression: 1.5 AT is 0.5 higher (9.8 − 9.3). Both still use fuel 92. The compression step is not a fuel-grade change in this catalogue.
Boost is No on both. Layout is Front, transverse on both. Fuel system is Distributed injection (multi-point) on both. Cylinder count and arrangement are 4 Inline on both. Do not read 1.5 AT as a different engine architecture: the data do not describe a second bank, a turbo, or a different drive.
Gearbox and drive: no extra money for a different layout
1.3 AT and 1.5 AT are both Automatic, 5, FWD. There is no measured manual, no extra ratio, no AWD, no RWD. If the buyer’s question is “should I pay for a different transmission or drive,” this catalogue answers no: those fields do not change between versions. The letters AT in both names match that: both are Automatic.
Performance and economy (mpg): not measured on either version
0–100 is not measured on 1.3 AT. 0–100 is not measured on 1.5 AT. Top speed is not measured on 1.3 AT. Top speed is not measured on 1.5 AT. City, highway, and mixed consumption are not measured on 1.3 AT. City, highway, and mixed consumption are not measured on 1.5 AT. CO2 is not measured on both.
You cannot rank these versions by 0–100, top speed, or mpg using this dataset. The 8 hp and 18 Nm gaps are real; converting them into seconds or litres per 100 km would invent numbers. Euro 2 is measured only on 1.5 AT; 1.3 AT emissions class is not measured — that is a labelling gap, not a measured “cleaner” or “dirtier” result.
Dimensions, weight, tank, wheels
Kerb weight is not measured on 1.3 AT. Kerb weight is not measured on 1.5 AT. Gross weight is not measured on both. Tank is not measured on both. Wheel sizes are not measured on both. Ground clearance is 145 on 1.3 AT and 145 on 1.5 AT.
Weight per horsepower cannot be calculated: mass is not measured. A “lighter 1.3” or “heavier 1.5” story would be invention. Front suspension is Independent, spring on both. Rear suspension is not measured on both. Front brakes are Disc on both. Rear brakes are not measured on both. Clearance, front suspension type, and front brake type do not pick a winner.
Which version to choose
Choose 1.5 AT if the numbers you care about are torque and the only measured eco class. 1.5 AT is 94 hp vs 86 hp on 1.3 AT (+8 hp), 128 Nm vs 110 Nm (+18 Nm), torque peak 3400 rpm vs 5200 rpm (1 800 rpm earlier), 1498 vs 1342 cm³ (+156 cm³), compression 9.8 vs 9.3 (+0.5), and Euro 2 vs not measured. Specific torque is higher on 1.5 AT (≈ 85.45 vs ≈ 81.97 Nm per litre). Gearbox, drive, fuel 92, FWD, Automatic 5, No boost, and clearance 145 stay the same, so the extra displacement is what you are buying — not a different chassis spec in this table.
Choose 1.3 AT if you want the higher specific power and the only fully specified small-displacement Automatic. 1.3 AT makes ≈ 64.1 hp per litre against ≈ 62.8 on 1.5 AT, lists 4 valves per cylinder (not measured on 1.5 AT), and lists bore and stroke 78.7 × 69 (not measured on 1.5 AT). Absolute output is lower: 86 hp and 110 Nm, with torque not arriving until 5200 rpm. If the use case is low load and you are ranking engines by power per litre rather than peak Nm, 1.3 AT is the denser power figure. It does not buy a smaller tank, lower mass, or better mpg here — those are not measured.
Do not choose by generation, body, drive, or gearbox. 1 generation, Sedan, FWD, Automatic 5, years 2003–2009: identical for both. Do not choose by 0–100, top speed, mpg, kerb weight, or wheels: not measured on 1.3 AT and not measured on 1.5 AT. Do not invent a third trim: the data list two versions only.
Prices are not in this dataset, so “what the extra money buys” is only the spec delta: 8 hp, 6 kW, 18 Nm, 156 cm³, 0.5 compression, 1 800 rpm earlier torque, and a measured Euro 2 label on 1.5 AT. If that delta is the reason to buy, 1.5 AT is the version the numbers point to. If it is not, 1.3 AT is the same Automatic FWD Sedan with 86 hp and a more complete small-engine spec sheet (valves, bore × stroke), not a different car.
