Do engine stats change?

As a newby, not really sure how it goes but do they change once in while?
and what´s the point of having that many engine providers if the general amount of teams use only 3. Is it only down to the price of the engine?
In other words, why should I choose anything else other than e.g Murk?

Thanks in advance.

Just get Murk :)
The engines don't improve, only worn engines with low %, e.g. after you drove 3 races with an engine, you might want to replace them.

This man is better than John Cena.


Anyways to your post OP, Suppliers have recieved one update since their revamp a few months ago. Current plan is to flatline all suppliers to generate a bonus to your car in correspondance towards the upcoming design system's Attribute system. Instead of looking for the best all the time, it'll be down to personal preference with each giving a bonus to a car attribute.

David - this man you show here has been in need of an attitude adjustment for a long long time.

but about the answers, just as what I expected. Thanks
