An ethanol vehicle with a certified conversion kit must comply with the same requirement as for petrol. And the requirements during a certification test are the same, regardless of the age of the vehicle.

A certified kit is tested on petrol as well as E85 – newer vehicles from the manufacturers are tested only on petrol and are still allowed for use with for example E85.

Ethanol fuel has lower energy content and therefore the fuel consumption is 25-35 % higher, which leads to increased CO and HC emissions.
The regulations do not take into consideration that the CO emissions (quickly transformed to CO2) from E85 are 70 % renewable (part of the circulation) and that our analyses show that 90 % of the HC emission are fairly harmless alcohol emissions.

The emission requirements can be found in several FAQ under Engine.
