Kia Potentia: which version to buy (1992–2001)

The Kia Potentia ran as 1 generation from 1992-01-01 to 2001-12-31, only as a Sedan, with 5 versions. There is no second generation to “step up to,” so the buying choice is entirely inside this one run: 2.0 AT, 2.2 AT, 2.2 MT, 2.5 AT, and 3.0 AT. All five are Gasoline, RWD, unboosted (No), and share a 70 L tank.

There is no second generation to “step up to,” so the buying choice is entirely inside this one run: 2.0 AT, 2.2 AT, 2.2 MT, 2.5 AT, and 3.0 AT. All five are Gasoline, RWD, unboosted (No), and share a 70 L tank. What changes is displacement, cylinder count and layout, valves per cylinder, gearbox, power, torque, top speed, and — where measured — kerb weight.

Generations: what one generation actually gives you

1 generation (1992-01-01 to 2001-12-31) is a Sedan with 5 versions and no restyling split in the data. Production start and stop are the same for every version, so you are not choosing a facelift year — you are choosing an engine and a gearbox.

Chassis language is the same on every version: Independent, spring front and rear; Ventilated disc front. Rear brakes are Disc on 2.0 AT, 2.2 AT, 2.2 MT, and 2.5 AT, and Disc ventilated only on 3.0 AT. Ground clearance is not measured on all five. Wheel sizes are not measured on all five. Gross weight is not measured on all five. Fuel consumption (city, highway, mixed) is not measured on all five. 0–100 is not measured on all five. CO2 and eco class are not measured on all five.

That means a “which to buy” call cannot rest on mpg, 0–100, or tyre size. It rests on power, torque, top speed, kerb weight where given, and how the engines are built.

3.0 AT200 (147 @ 6000)260 @ 45002954956, V-shaped4NoAutomatic, 4RWD

All five use Distributed injection (multi-point) and 95 fuel. Compression: 2.0 AT 9.5; 2.2 AT and 2.2 MT 9.8; 2.5 AT 10.5 (highest); 3.0 AT 8.9 (lowest). Bore × stroke: 2.0 AT 86 × 86; 2.2 AT / 2.2 MT 86 × 94; 2.5 AT 80 × 82.8; 3.0 AT 90 × 77.4.

Power per litre (hp ÷ displacement in litres): 2.0 AT 70.1 hp/L; 2.2 AT and 2.2 MT 54.9 hp/L; 2.5 AT 70.1 hp/L; 3.0 AT 67.7 hp/L. The 2.2 pair is the least specific output — 15.2 hp/L below 2.0 AT — even though displacement is 186 cc larger.

Torque per litre: 2.0 AT 90.6 Nm/L; 2.2 85.2 Nm/L; 2.5 AT 74.5 Nm/L; 3.0 AT 88.0 Nm/L. 2.5 AT is the peak-power six that does not add torque over the 2.2 fours: both sit at 186 Nm.

Performance and economy: what is measured, what is not

0–100 km/h is not measured for 2.0 AT, 2.2 AT, 2.2 MT, 2.5 AT, and 3.0 AT. City, highway, and mixed consumption are not measured for all five. You cannot rank versions on mpg from this catalogue.

Top speed is measured:

2.5 AT is 8 km/h faster than 2.0 AT, 13 km/h faster than 3.0 AT, and 14 km/h faster than either 2.2. 3.0 AT has the most power (200 hp vs 175 on 2.5 AT, a gap of 25 hp) and the most torque (260 vs 186 Nm, +74 Nm), yet its listed top speed is 13 km/h below 2.5 AT. That is the number in the data; it is not a 0–100 figure.

2.2 AT and 2.2 MT share 184 km/h, 120 hp, and 186 Nm. Switching Automatic 4 for Manual 5 does not change the listed top speed.

Dimensions and weight: kerb, tank, and what is missing

Tank: 70 L on every version — no range advantage by spec.

Kerb weight:

Gross weight: not measured on all five. Ground clearance: not measured on all five. Wheel sizes: not measured on all five.

Weight per horsepower (kerb ÷ hp), where kerb exists:

3.0 AT carries 140 kg more than 2.0 AT for 60 extra hp (200 − 140). That is 2.33 kg per extra hp. 2.5 AT adds 115 kg over 2.0 AT for 35 extra hp — 3.29 kg per extra hp. From 2.5 AT to 3.0 AT you add only 25 kg for 25 hp (1.00 kg per extra hp) and 74 extra Nm.

2.2 MT is 5 kg lighter than 2.0 AT but 20 hp down (140 − 120), so kg/hp is 1.71 worse.

Which version to choose

There is only 1 generation, so “newer generation” is not a lever. All five are RWD Gasoline sedans with the same tank and the same unboosted injection type. Buy on engine size, cylinder layout, gearbox, and the measured speed/weight numbers.

Buy 2.0 AT if you want the strongest four-cylinder package. 2.0 AT makes 140 hp and 181 Nm from 1998 cc, 4 Inline, 4 valves per cylinder, Automatic 4. Versus 2.2 AT / 2.2 MT it has 20 more hp (140 vs 120) from 186 cc less displacement, and 6 km/h more top speed (190 vs 184). Specific output is 70.1 vs 54.9 hp/L. Peak torque arrives at 4000 rpm, not 5500. Compression is 9.5 vs 9.8. Kerb 1475 kg is only 5 kg above 2.2 MT. The 2.2 fours use 3 valves per cylinder; 2.0 AT uses 4. If the question is “four cylinders, automatic,” 2.0 AT beats 2.2 AT on power, top speed, and hp per litre. What 2.2 AT adds is 5 Nm (186 vs 181) and 186 cc — not enough to offset 20 hp.

Buy 2.2 MT only if you specifically want Manual 5. Engine numbers match 2.2 AT: 120 hp, 186 Nm, 2184 cc, 4 Inline, 3 valves, compression 9.8, 86 × 94, top speed 184. The difference is gearbox: Manual 5 versus Automatic 4. Kerb is measured at 1470 kg; 2.2 AT kerb is not measured, so you cannot claim the automatic is heavier from this data. Top speed does not change with the manual. This is the lightest measured car (1470 kg) but the weakest kg/hp among cars with a kerb figure (12.25). Do not buy 2.2 MT for power; buy it for the 5-speed Manual.

Do not buy 2.2 AT if the alternative is 2.0 AT or 2.5 AT, unless you need this exact 2184 cc Automatic 4 calibration. It is the same engine as 2.2 MT with Automatic 4, 120 hp, 184 km/h, and kerb not measured. Against 2.0 AT it is down 20 hp and 6 km/h. Against 2.5 AT it is down 55 hp and 14 km/h, with the same 186 Nm as 2.5 AT — so the six does not even cost you a torque deficit versus this four; it only costs displacement and cylinder count.

Buy 2.5 AT if the priority is the highest listed top speed and a 6-cylinder Automatic without the 3.0’s extra mass. 2.5 AT: 175 hp, 186 Nm, 2497 cc, 6 V-shaped, 4 valves, compression 10.5, Automatic 4, kerb 1590 kg, top speed 198 km/h. Versus 2.0 AT: +35 hp, +5 Nm, +115 kg, +8 km/h. Versus 3.0 AT: −25 hp, −74 Nm, −25 kg, +13 km/h. Torque matches 2.2 at 186 Nm, so 2.5 AT is not the torque car; it is the speed-and-rev six (peak hp at 6000, torque at 4000). Highest compression in the line. Rear brakes remain Disc, not ventilated.

Buy 3.0 AT if the priority is peak power, peak torque, and the only ventilated rear discs. 3.0 AT: 200 hp, 260 Nm, 2954 cc, 6 V-shaped, 4 valves, compression 8.9, Automatic 4, kerb 1615 kg, top speed 185 km/h, rear Disc ventilated. Versus 2.5 AT you pay 25 kg for 25 hp and 74 Nm. Versus 2.0 AT you pay 140 kg for 60 hp and 79 Nm (260 − 181). Best kg/hp (8.08). Lowest compression (8.9). Top speed (185) sits 5 km/h below 2.0 AT and 13 below 2.5 AT — so 3.0 AT is not the “fastest on the sheet”; it is the torque and power car. Bore × stroke 90 × 77.4 is the oversquare six; 2.5 AT is 80 × 82.8.

Direct arithmetic shortlist

Practical pick: 2.0 AT as the four-cylinder default; 2.5 AT if you want the 6 V-shaped and the 198 km/h figure; 3.0 AT if 260 Nm and 200 hp matter more than the 185 km/h top speed; 2.2 MT only for Manual 5; skip 2.2 AT unless that exact automatic four is required. Prices are not in this dataset, so “what the extra money buys” here means what the extra cubic centimetres, cylinders, and kilograms buy in hp, Nm, and km/h — not a invoice delta.

Reliability and typical faults are not measured in this data; do not treat silence as a clean bill. Fuel economy and 0–100 are not measured; do not infer them from top speed. Dimensions beyond kerb (where given) and the 70 L tank are not measured.
