There is really no quick way around this one. No matter what you do, it's going to be approx. a 65-75 hours grind (this is total car use time, so it includes all time using that manufacturer in the championships + time spent grinding so more realistically 35-40 hours of your time solely for this achievement). But, there are some ways to make it less painful.

This is the method I've been doing the past few days and it has made it seem like a breeze:

Mode: Free Play.
Car: Select the car in which you would like to boost Affinity with.
Track: Indianapolis Motor Speedway - Oval
Max Drivatars: 15
Laps: Anywhere from 20-50 but at least 20. I will give more info on laps later in the solution.
Collision Mode: Always Off. This is just so you don't have to worry about hitting the other cars, it serves no other purpose than that.

Now all you have to do is race.

The reason for the 20 laps is because that will guarantee one affinity level every race, and will only take about 15-20 minutes. 40 laps will guarantee 2 levels but will take about 30-40 min. 50 laps will guarantee 2.5 levels but will take about 45-60 min. The time it takes really depends on the car you are driving. Each lap is equivalent to 1,000 EXP, and you need 20,000 EXP per affinity level, hence the 20 lap minimum. Of course you could do less, depending on how much you would like to space out race time. The intervals I would recommend though are 20, 40, or 50 laps. (50 is the max amount of laps allowed)

Level 25 info: (this has been consistent over all 4 manufacturers I have done)
Total XP: 485,000
Total Time Driven: 8-9 hours per car.

Happy grinding!!

Thank you to peacemak3r for this one:

Alternatively, you can do the career races that yield large XP rewards, such as the ones that give 7,000-10,000 XP. Unfortunately it may be tough to find the high XP races for the specific manufacturer you are boosting.

***EDIT 2***
Credit goes to RzrsS for this one:

If you would like to do this with little to no effort:
Set up a private multiplayer lobby. Do a 1 mile drag with ten heats and a 5 second end race timer. Rubber band your RT. You will receive 10000 XP every 10/12 minutes. It will take a slight amount of time more, but will require no effort!
Note: You will have to press (x) still after every race, so you will have to monitor the game. I'd just advice doing something else in the process such as watching Netflix on a laptop or play a PC game on a laptop if that is an available option to you.

"better/faster way to rank up X Class , and P class cars
just thought i would tell you guys about this ive been doing it all day/night and its working faster than indy 50 laps i realized it while trying to get in the top100 on the leaderboards for x class cars on certain tracks , if you enter rival mode and play tracks like Prague Full circuit and bathurst australia if you do about 10 laps which with X and P class cars is just over minute if your a decent driver you will get like 22 thousand xp every 13mins which is alot better than indy oval and alot more fun especially if your trying to get a fast lap try it out for your self and see , you also get quite abit more money for the rival bonus anyway give it a try its defo faster and less boring than indy only thing is its only good for X and P class cars peace
sorry about the grammer lol"
