ULEZ compliant car models

Manufacturers moved to cleaner engines at different times, but the law set a last date for every new car. Petrol cars sold new from January 2006 had to meet Euro 4. Diesel cars sold new from September 2015 had to meet Euro 6.

So a 2016 diesel Golf passes, while a 2014 one usually doesn't, even though they look the same. Many petrol cars from 2001 to 2005 pass too, and so do some diesels from late 2014. TfL sets out these dates.

Audi sold both with petrol and diesel engines, so the fuel on your logbook decides which date counts.

The X5 is a big 4x4. For Euro 4, cars over 2,500 kg maximum mass followed the later van dates, so check a petrol X5 from 2006 or 2007 by its plate.

Dacia began selling the Duster in the UK in 2013, so a petrol one passes. A diesel one needs a first registration from September 2015.

The current Fiat 500 went on sale in 2007, so nearly every petrol one passes. The electric 500 and the electric Mini meet the rules at any age.

The Fiesta, Focus and Kuga follow the car dates. The Transit is a van, so a diesel Transit follows the van date instead.

Hybrid versions of either are judged on their petrol engine, so they pass like a petrol car of the same age.

The i10 is a small city car first sold in 2008, so almost every petrol one passes. A Sportage hybrid is judged on its petrol engine.

Both are large saloons and estates. The XF arrived in 2008, so every petrol XF should meet Euro 4. For a diesel of either, look for September 2015 or later.

The original Defender was built until early 2016, so a diesel one made before September 2015 usually pays. Heavy 4x4s followed the later van dates for Euro 4, so check an older petrol model by its plate. The Evoque went on sale in 2011, and a petrol one passes.

The Juke arrived in 2010 and the Qashqai in 2007, so petrol ones pass. An older Micra from before 2006 may still pass, as many petrol cars from 2001 do.

The 208 went on sale in 2012, so every petrol one passes. The electric e-208 passes at any age.

Every Prius is a petrol hybrid, so it's judged as a petrol car. The Aygo arrived in 2005, and petrol ones from 2006 usually pass.

Both came with petrol and diesel engines. The XC60 plug-in hybrid is judged on its petrol engine.

The Golf and Polo follow the car dates. The Transporter is a van, so a diesel one follows the van date of September 2016.
