Mazda Xedos 9: generations compared: what the restyling actually changed
The catalogue lists two entries, not two separate generations: 1 generation (1993-09-01 to 2000-07-31) and 1 generation, restyling (2000-08-01 to 2002-09-30). Each has six named versions: 2.0 MT, 2.0 AT, 2.3 MT, 2.3 AT, 2.5 MT, 2.5 AT.

Arithmetic on the given figures, restyling versus 1 generation:
- Fuel tank: 68 L on every restyling version versus 60 L on every 1 generation version — +8 L, about 13% more volume.
- Front brakes: Ventilated disc on all six restyling versions versus Disc on all six 1 generation versions.
- 2.0 2.0 MT: same 143 hp, 105 kW at 6000 rpm, 176 Nm at 4900 rpm, 1995 cm³, kerb 1415 kg, gross 1940 kg, 140 mm clearance — but 0–100 falls from 10.7 s to 8.6 s (−2.1 s) and top speed rises from 202 to 220 km/h (+18 km/h).
- 2.5 power: restyling 2.5 MT / 2.5 AT make 170 hp / 125 kW; 1 generation 2.5 MT / 2.5 AT make 167 hp / 123 kW (+3 hp / +2 kW after restyling). Torque stays 212 Nm at 4900 rpm, displacement 2497 cm³.
- 2.5 2.5 MT speed: 1 generation 2.5 MT is 8.6 s and 220 km/h; restyling 2.5 MT is 10.7 s and 202 km/h — the later 2.5 is 2.1 s slower and 18 km/h lower despite +3 hp.
- 2.3 2.3 AT: 211 hp / 155 kW at 5300 rpm, 290 Nm at 3700 rpm, 2255 cm³, 9.4 s, 230 km/h, 1500 kg kerb, 1985 kg gross, 140 mm — identical on both sides except tank 60 L versus 68 L and front Disc versus Ventilated disc.
- Boost on 2.3 MT: 1 generation 2.3 MT is listed Nadduv_en No; restyling 2.3 MT is Compressor. Peak figures stay 211 hp and 290 Nm. Restyling 2.3 MT has measured 9.4 s and 230 km/h; 1 generation 2.3 MT 0–100, top speed, kerb weight and engine location are not measured.
Ground clearance is 140 mm on most versions. The exceptions at 120 mm are 2.0 AT in both periods and 1 generation 2.3 MT. Wheel size is not measured on any version.

Power per litre (hp ÷ litres from the listed cm³): 2.0 MT / 2.0 AT 143 ÷ 1.995 ≈ 71.7 hp/L; restyling 2.3 MT / 2.3 AT and 1 generation 2.3 AT 211 ÷ 2.255 ≈ 93.6 hp/L; restyling 2.5 MT / 2.5 AT 170 ÷ 2.497 ≈ 68.1 hp/L; 1 generation 2.5 MT / 2.5 AT 167 ÷ 2.497 ≈ 66.9 hp/L. The 2.3 Compressor pair is the densest engine in the catalogue; the naturally aspirated 2.5 is the least dense even though it is the largest.
Compression: 2.0 MT 10; 2.0 AT 9.5 (both periods); 2.3 MT / 2.3 AT 10; 2.5 MT / 2.5 AT 9.2. Bore × stroke: 2.0 78 × 69.6; 2.3 80.3 × 74.2; 2.5 84.5 × 74.2.
Engine location: Front, transverse on restyling 2.0 MT, 2.0 AT, 2.3 MT, 2.3 AT, 2.5 MT, 2.5 AT and on 1 generation 2.0 MT, 2.3 AT, 2.5 MT, 2.5 AT. 1 generation 2.0 AT is Central. 1 generation 2.3 MT engine location is not measured.
Performance and economy
Measured 0–100 km/h and top speed:
- Fastest 0–100: restyling 2.0 MT 8.6 s and 1 generation 2.5 MT 8.6 s (tie).
- Highest top speed: restyling 2.3 MT, restyling 2.3 AT, 1 generation 2.3 AT — 230 km/h.
- Slowest measured 0–100: restyling 2.5 MT, restyling 2.5 AT, 1 generation 2.0 MT, 1 generation 2.5 AT — 10.7 s.
- Lowest measured top speed: those same 10.7 s cars — 202 km/h, except restyling 2.0 MT which is 8.6 s / 220 km/h.
Not measured 0–100 and top speed: restyling 2.0 AT, 1 generation 2.0 AT, 1 generation 2.3 MT.
Restyling 2.3 MT and restyling 2.3 AT share 9.4 s and 230 km/h: the 4 Automatic does not change the listed sprint versus the 5 Manual on that engine. Restyling 2.5 MT and restyling 2.5 AT likewise share 10.7 s and 202 km/h. On 1 generation the 2.5 split: 2.5 MT 8.6 s / 220 km/h versus 2.5 AT 10.7 s / 202 km/h — +2.1 s and −18 km/h for the Automatic.
City, highway and combined consumption are not measured on all twelve versions. CO2 is not measured. Eco class is not measured.
Dimensions and weight
Kerb / gross / clearance / tank:
- Restyling 2.0 MT: 1415 / 1940 kg, 140 mm, 68 L.
- Restyling 2.0 AT: kerb not measured, gross not measured, 120 mm, 68 L.
- Restyling 2.3 MT and 2.3 AT: 1500 / 1985 kg, 140 mm, 68 L — +85 kg kerb and +45 kg gross versus restyling 2.0 MT / 2.5 MT.
- Restyling 2.5 MT and 2.5 AT: 1415 / 1940 kg, 140 mm, 68 L — same mass as restyling 2.0 MT.
- 1 generation 2.0 MT: 1415 / 1940 kg, 140 mm, 60 L.
- 1 generation 2.0 AT: kerb not measured, gross not measured, 120 mm, 60 L.

- 1 generation 2.3 MT: kerb not measured, gross 1985 kg, 120 mm, 60 L.
- 1 generation 2.5 MT and 2.5 AT: 1415 / 1940 kg, 140 mm, 60 L.
kg per hp where kerb is measured: restyling 2.0 MT 1415 ÷ 143 ≈ 9.9 kg/hp; restyling 2.3 MT / 2.3 AT and 1 generation 2.3 AT 1500 ÷ 211 ≈ 7.1 kg/hp; restyling 2.5 MT / 2.5 AT 1415 ÷ 170 ≈ 8.3 kg/hp; 1 generation 2.5 MT / 2.5 AT 1415 ÷ 167 ≈ 8.5 kg/hp; 1 generation 2.0 MT 1415 ÷ 143 ≈ 9.9 kg/hp.
Payload from listed masses: 1940 − 1415 = 525 kg on the 2.0/2.5 cars with both figures; 1985 − 1500 = 485 kg on the 2.3 cars with both figures. Wheel sizes are not measured. Suspension is Independent, spring front and rear on every version.
Which version to choose
There is no price in the data, so “what you get extra” is only displacement, power, mass, tank, brakes and the measured sprint.
If the target is the lowest kg/hp and the highest top speed: restyling 2.3 MT or restyling 2.3 AT (or 1 generation 2.3 AT if the earlier tank of 60 L is acceptable). 211 hp, 290 Nm, 93.6 hp/L, 7.1 kg/hp, 9.4 s, 230 km/h. Versus restyling 2.0 MT that is +68 hp, +114 Nm, +85 kg kerb, +0.8 s to 100 (9.4 versus 8.6), +10 km/h top speed. The 2.3 is heavier and 0.8 s slower to 100 than the restyling 2.0 Manual, but 68 hp stronger and 10 km/h faster at the top. Restyling 2.3 MT and 2.3 AT match on every measured performance and mass figure; pick Manual 5 versus Automatic 4, not a different engine.
If the target is the fastest 2.0: restyling 2.0 MT only — 8.6 s, 220 km/h, 1415 kg, Ventilated disc, 68 L, Front, transverse, compression 10. Do not treat 1 generation 2.0 MT as the same car: same 143 hp and 1415 kg, but 10.7 s and 202 km/h, Disc front, 60 L. Restyling 2.0 AT and 1 generation 2.0 AT leave 0–100, top speed and kerb not measured; both sit at 120 mm clearance (20 mm lower than the 140 mm 2.0 MT). 1 generation 2.0 AT is also the only version with engine location Central.
If the target is a 2.5 without a compressor: 1 generation 2.5 MT is the one with a measured 8.6 s and 220 km/h at 167 hp. Restyling 2.5 MT and restyling 2.5 AT add 3 hp (170) and the 68 L tank plus Ventilated disc, but the listed sprint is 10.7 s and 202 km/h — the same as 1 generation 2.5 AT and 1 generation 2.0 MT. So the later 2.5 does not buy a quicker catalogue time. Torque is 212 Nm on all four 2.5 versions.
If the target is 1 generation 2.3 MT: treat it as a different row from restyling 2.3 MT. Same 211 hp and 290 Nm and 2255 cm³, but boost No, 0–100 not measured, top speed not measured, kerb not measured, engine location not measured, clearance 120 mm, tank 60 L, front Disc. 1 generation 2.3 AT is the 2.3 in that period with a full measured set (Compressor, 9.4 s, 230 km/h, 1500 kg, 140 mm).
If the target is range between fills: restyling, any of the six names — 68 L versus 60 L. Consumption is not measured, so litres per 100 km cannot be turned into kilometres of range.
If the target is the lightest kerb among measured cars: 1415 kg on restyling 2.0 MT, restyling 2.5 MT, restyling 2.5 AT, 1 generation 2.0 MT, 1 generation 2.5 MT, 1 generation 2.5 AT. The 2.3 cars that publish kerb are 1500 kg.
Problems and reliability: the data do not list faults, service intervals or failure rates. Those items are not measured here.
Short map: restyling 2.0 MT for the 8.6 s 2.0; 1 generation 2.5 MT for the 8.6 s 2.5; restyling 2.3 MT or restyling 2.3 AT (or 1 generation 2.3 AT) for 211 hp and 230 km/h; skip using 2.0 AT (either period) and 1 generation 2.3 MT as performance picks because 0–100 and top speed are not measured.
