Road tax for a 2006 Saab 9-5
The Vehicle Certification Agency lists 32 petrol and diesel versions of the Saab 9-5 in its data from May 2006 to May 2007, from 174 to 258 g/km CO2 [3]. A car first registered from 1 March 2001 to 31 March 2017 is taxed by CO2 band, so that is 6 bands from H to M: from £325 to £790 a year at the 2026/27 rates [2]. These are the bands for a car registered from 23 March 2006. 15 of the listed versions are over 225 g/km: a car like that registered before 23 March 2006 pays band K (£445 a year) instead.
| Band | 12 months | CO2 g/km | Petrol versions | Diesel versions |
|---|---|---|---|---|
| H | £325 | 174 | 0 | 1 |
| I | £360 | 184 | 0 | 1 |
| J | £410 | 199 | 0 | 1 |
| K | £445 | 204–225 | 13 | 1 |
| L | £760 | 226–255 | 13 | 0 |
| M | £790 | 258 | 2 | 0 |
Versions listed, not cars sold: this does not say how common each band is. The CO2 figure on the car's V5C log book decides its band. Car tax calculator for a 2006 car
Car tax and ULEZ for a 2006 car
A car first registered in the UK in 2006 was issued a 55 (January–February), 06 (March–August) or 56 (September–December) plate, unless it was registered in Northern Ireland (no age identifier) or has since moved to a private plate. An imported one is plated when first registered here, so its plate can be newer than its first-use year. 06 plates
A 2006 car is taxed by its CO2 emissions band (A to M), shown on the V5C logbook. [2]
For the London ULEZ, a 2006 petrol usually meets Euro 4, and a 2006 diesel usually does not meet Euro 6. The Euro standard of the car decides, not the year alone. [4] ULEZ checker
