Which version to choose

All Signum versions in this catalogue are FWD Hatchback 5-door. Choice is engine, gearbox, and the two date bands.

Lowest combined fuel: restyling 1.9 MT (100 hp) and original 2.0 MT (100 hp, Diesel) both at 5.9. Restyling 1.9 MT (100 hp) is 100 hp, 260 Nm, 14 s, 180 km/h. Original 2.0 MT (100 hp, Diesel) is 100 hp, 230 Nm (30 Nm less), 14 s, 185 km/h (5 km/h more), Manual 5 rather than 6. Original 1.9 MT (120 hp) uses 6.0 combined with 120 hp and 12 s; original 1.9 MT (150 hp) uses 6.1 combined with 150 hp, 320 Nm, 10.4 s, 209 km/h — 3.6 s quicker than the 100 hp restyling diesel and 29 km/h faster. Original 1.9 AT (150 hp) is the diesel Automatic: 10.7 s, 205 km/h, combined 7.2 (1.1 more than the 150 hp 1.9 MT).

Gasoline four-cylinder without Turbo: original 1.8 MT is the lightest car here (1405 kerb) at 122 hp and 12.2 s. Restyling 1.8 MT adds 18 hp (140 vs 122) and 8 Nm (175 vs 167), cuts 0–100 by 0.9 s, and raises top speed by 10 km/h; kerb is 20 higher (1425). Restyling 1.8 MTA is the only Robotic: same 140 hp and 7.9 combined as restyling 1.8 MT, but 0–100 and top speed are not measured. 2.2 MT (155 hp) is 2.4 s quicker than 2.2 AT (155 hp) in both generation records (9.8 vs 12.2) and 13 km/h faster (211 vs 198); combined fuel is 8.1 vs 9.1 (Automatic uses 1.0 more). Direct injection (direct) and compression 12 apply to these 2198 cc versions.

Gasoline four-cylinder with Turbo: 2.0 MT (175 hp) is 175 hp / 265 Nm / 9.4 s / 220 km/h in both records. Restyling gives it Manual 6; the original gives Manual 5. Combined fuel is 8.9 in both. Versus restyling 2.2 MT (155 hp), 2.0 MT has 20 hp and 45 Nm more, is 0.4 s quicker, 9 km/h faster, and uses 0.8 more combined.

Six-cylinder without Turbo: 3.2 MT / 3.2 AT (211 hp, 3175 cc, 6 V-shaped, boost No) sit in both records with the same performance: 7.9 s / 237 km/h (MT) and 8.5 s / 235 km/h (AT). Combined 10.3 (MT) vs 10.7 (AT). 3.2 MT is 0.7 s slower than restyling 2.8 MT (250 hp) and 13 km/h slower, with combined 10.3 vs 10.6.

Six-cylinder with Turbo (restyling only): 2.8 MT (230 hp) and 2.8 AT (230 hp) share 7.6 s and 243 km/h and 10.6 combined. 2.8 MT (250 hp) is the performance peak: 7.2 s, 250 km/h, 250 hp, 350 Nm, combined still 10.6. 2.8 AT (250 hp) keeps 7.6 s but reaches 247 km/h and uses 11.2 combined — 0.6 more than the 250 hp Manual, and city use 17.4 vs 15.7. Kerb on 2.8 MT (230 hp) is 1645, 65 more than 2.8 MT (250 hp) at 1580.

Diesel 2.2: original 2.2 MT (125 hp) 11.2 s / 201 km/h / combined 6.3; original 2.2 AT (125 hp) 12.2 s / 198 km/h / 7.6. Versus original 2.2 MT (155 hp Gasoline), the Diesel 2.2 MT (125 hp) has 30 hp less, 60 Nm more (280 vs 220), is 1.4 s slower, 10 km/h slower, and uses 1.8 less combined (6.3 vs 8.1).
