Generation 2 restyling (1999–2003) — kerb / gross kg:
- 2.0 MT 101 hp: kerb 2145, gross 1600 (values as recorded)
- 2.2 MT 120 hp: 1600 / 2145

Among restyling versions with both masses measured, the lightest kerb is 1510 kg (2.0 MT 136 hp Gasoline). The 2.5 150 hp diesels sit at 1610 kg kerb — 100 kg above that 2.0 MT. Highest recorded gross in restyling is 2170 kg.
Problems and reliability
Fault lists, recall counts, and reliability scores are not measured in this dataset. What the numbers do show: every version is RWD with Independent, spring suspension both ends and Ventilated disc / Disc brakes; eco class and CO2 are not measured; wheel size is not measured. Several diesel and gasoline versions have consumption not measured, so economy comparisons are only valid where all three L/100 km fields exist.
Which version to choose
Compare only with figures in the tables.
If mixed consumption is the filter. The lowest measured mixed figure is restyling 2.2 MT 120 hp Diesel at 7.1 L/100 km (city 9.6, highway 5.6). Generation-2 2.5 AT / 2.5 MT 131 hp Diesel sit at mixed 7.9. Restyling 2.5 AT / 2.5 MT 150 hp Diesel are mixed 7.6 with 0–100 10.5 s and top 208 km/h — 4.5 s quicker than the 101 hp 2.0 MT diesel (15 s, 186 km/h). Gasoline mixed figures start at 9.3 (generation-2 2.0 136 hp; restyling 2.0 MT 136 hp) and reach 11.1 on the 3.0 pair.
If acceleration and top speed are the filter. The fastest 0–100 in the extract is generation-2 3.0 MT at 8.5 s and 243 km/h (211 hp, 270 Nm, 2962 cc, Gasoline, 6 V-shaped, boost No, Manual 5, RWD). The 3.0 AT is 8.8 s and 240 km/h with the same peak power and torque. Those two versions are absent from the restyling list. In restyling, 2.5 MT 170 hp Gasoline is 9.5 s and 228 km/h; 2.5 AT 170 hp is 10.5 s and 223 km/h. Restyling 2.5 150 hp diesels match 10.5 s with 208 km/h and 300 Nm — 70 Nm more than the 170 hp restyling 2.5 AT Gasoline (230 Nm) and 73 Nm more than restyling 2.5 MT 170 hp Gasoline (227 Nm).
If you want a diesel with measured economy and a four-cylinder layout. Restyling 2.2 MT 120 hp: 2171 cc, Inline 4, Turbo, 280 Nm at 1600 rpm, Manual 5, RWD, mixed 7.1. The 101 hp 2.0 MT diesel (both periods) has the same 205 Nm at 1650 rpm and the same 15 s / 186 km/h, but consumption is not measured.
If you want the 136 hp gasoline four. Generation-2 2.0 MT and 2.0 AT 136 hp both do 11 s and 210 km/h; mixed 9.3. Restyling 2.0 MT 136 hp keeps 11 s / 210 km/h / mixed 9.3; restyling 2.0 AT 136 hp slows to 13 s / 195 km/h / mixed 10.2. Restyling 2.2 MT / 2.2 AT 144 hp both list 10.5 s and 210 km/h with mixed 9.6 — 8 hp and 20 Nm above the 136 hp 2.0, displacement 2198 versus 1998.
If you want six cylinders without the 3.0. Generation-2 2.5 AT / 2.5 MT 170 hp Gasoline: 9.5 s, 223 km/h, mixed 10.6, 2498 cc, 6 V-shaped. Diesel 2.5 131 hp in generation 2: 12 s, 200 km/h, mixed 7.9, 6 Inline, 2 valves per cylinder, compression 22. Restyling splits that diesel into 131 hp (2 valves, Automatic 4 or Manual 5) and 150 hp (4 valves, Automatic 5 or Manual 5, mixed 7.6).
Same name, different output — use horsepower. 2.0 MT appears as 101 hp Diesel and as 116 hp or 136 hp Gasoline. 2.0 AT appears as 116 hp and 136 hp. 2.2 MT appears as 120 hp Diesel and 144 hp Gasoline. 2.5 MT / 2.5 AT appear as 131 hp Diesel, 150 hp Diesel (restyling), and 170 hp Gasoline. Always keep the hp next to the name.
Chassis pattern does not change with version: RWD, Front, longitudinal, Independent, spring both axles, tank 75 L, clearance 140 mm. Choose on engine, gearbox, and the 0–100 / consumption rows that are actually measured.
