THE cars most likely to fail their MOT under new regulations have been revealed.
Tougher rules for roadworthiness checks come into force on Sunday, and with a bigger focus on emissions, these are the models that will be most affected.
The Peugeot 208 is the car most likely to fail tests
A recent investigation, conducted by Cazana, uncovered the motors most likely to fail their compulsory service based on their emissions levels.
And it’s bad news for owners of a Peugeot 208, with both the petrol and diesel versions of the hatchback voted most likely to fail under new MOT rules.
But only models from 2012-2015 produced a high potential failure rate, with newer editions of the French motor likely to be cleared.
Gathering data on all cars released from 2008, research found that the 2012-2015 Vauxhall Mokka would also have a high risk of failing, closely followed by the Chrysler Ypsilon.

Two out of the five cars least likely to fail are diesel
And despite being one of the smallest cars on the road, the Smart FourTwo Coupe is also likely to be hit hard by the rule changes, for all models from 2008-2015.
MOT changes are set to make it harder for diesel models to pass, but according to the research, petrol vehicles are just as likely to be affected.
Four out of the top five cars most likely to fail were petrol – and a diesel motor was actually found to be the most likely to pass.
BMW 1 Series hatchbacks made between 2008-2015 were most likely to sail through tough service checks with ease.
Vauxhall’s Mokka came in second on the failure list
While the Chrysler Ypsilon could also cause some concern for owners
When the MOT changes on May 20, mechanics will be given stricter guidelines on the level of toxic gases each type of car can produce.
An estimated 100,000 cars already fail the MOT on emissions, and that figure is expected to soar after this weekend.
Diesel particulate filters (DPF) will also now be checked as part of the test.
A large number of drivers have their DPFs removed rather than deal with them regularly becoming clogged – but having it removed or tampered with will now result in an instant fail.
The smoke test limit will also be slashed, with dirty diesels being handed a “major” fail they don’t meet standards.
Tom Wood, CEO of Cazana, commented: “Cazana’s insights are more important than ever in light of the coming MOT overhaul on May the 20th.
“As MOT regulations become even stricter, we need to be careful about the car choices we’re making so we don’t drive models that are likely to let us down.
