It depends on the fuel and the Euro emissions standard of the car, not on the model. Here is how 227,623 DVSA MOT tests of the Mercedes-Benz Slk with a recorded fuel, from 2022 to 2025 on cars aged 3 to 25 at test, split by fuel and first-use year, and which of them generally meet the London ULEZ and clean air zone standards.

Short answer, by fuel

Petrol: petrol cars first used in 2006 or later generally meet Euro 4, the standard for petrol cars. At least 46.3% of petrol Slk MOT tests (n=173,956) were on cars first used in 2006 or later, and 27.9% on cars first used in 2005 or earlier, which meet it only if built to Euro 4.
Diesel: diesel cars first used from September 2015 generally meet Euro 6; earlier diesels meet it only if built to Euro 6. At least 1.6% of diesel Slk MOT tests (n=53,667) were on cars first used in 2016 or later, and 31.7% on cars first used in 2014 or earlier, which meet it only if built to Euro 6.

Fuels and first-use dates

Share of Mercedes-Benz Slk MOT tests by fuel, and the share on cars first used late enough to meet the standard by date alone. We count by the car’s age at test, so cars close to a cut-off are left out of that share: it is a lower bound.

Mercedes-Benz Slk MOT tests 2022 to 2025 with a recorded fuel, on cars aged 3 to 25 at test (n=227,623). A fuel is listed when it has at least 1,000 tests.
Fuel	Tests (n)	Share	Meets by date if first used	Share that do
Petrol	173,956	76.4%	2006 or later	at least 46.3%
Diesel	53,667	23.6%	2016 or later	at least 1.6%

By first-use year

Every first-use year of the Mercedes-Benz Slk with enough MOT tests, and what the date alone says for each fuel. We do not have the fuel split for each year. A car first used in 2016 or later generally meets both standards.

Mercedes-Benz Slk MOT tests 2022 to 2025 by the year the car was first used, all fuels, cars aged 3 to 25 at test. A year is listed when it has at least 1,000 tests.

Compliance is decided for each car, not for a model. A zone checks the Euro emissions standard the car was built to, which is on the V5C log book or the maker’s certificate of conformity. The years here are a guide: many cars first used before a cut-off still meet it. Check one car with our ULEZ checker or TfL’s vehicle checker. Exemptions such as the disabled tax class or historic vehicles depend on the car and its keeper.
