Forza Motorsport 7

Nice efficiency here. When the race is done, choose "restart" (the win will already count as you can see in your achievement tracker if you use it) rather than choosing "next race", and then you just have to change your car and start again.

I don’t know if anyone is having the same problem but I’ve rented every car twice and the achievement tracker is showing one car to go.

Rage inducing

Sorry for the double-post.

I just wanted to say that I unlocked it. Follow the OP's method (by far the fastest) and use my list to keep track of what you have driven. Should be super easy.

Shadow Shifter, I also kept getting the "change your car" message without the race settings needing me to. When I got to choose the 2012 911 GT3 RS 4.0 to race, I got a pop up message "one driver doesn't have a car" and couldn't start the race until I changed the "allow upgrades" under the car restrictions. I do think there must be a bug somewhere in this achievement.
Your list is really helpful to keep track of what cars you've used.

Where is the 57 Speedster?

I kept getting "car restrictions have changed. You will need to select a new car" after picking restart etc. but only the current car was visible. This only happened when picking a car I owned.

Easily solved by going to race settings and just accepting them unchanged again and then selecting next car, but slightly prolongs the process. It even remembers where you were in your list of owned Porsches.

It just needs the next car selecting if you're renting as it doesn't remember the current type.

It took a minute to pop for me so don't freak out like I did if you are sure you did them all and it's not popping right away.

i kept thinking the macan was the cayenne when just scrolling through and felt really dumb lol

I'm stuck at 96% and checked off every car as I went along. Anybody else have this problem?

McNastyFilth, in this list of cars missing 1978 Porshe #78 MOMO 935/78, but i dunno, need this one or not.

What an embarrassingly glitchy achievement. I raced every car twice and most three times until it finally unlocked on the 1989 car. Also you don't need the 1978 Porsche, that's a DLC car.

Am I missing something here I can't find

2016 911 GT3 RS
2015 Macan Turbo
1957 356A Speedster

to buy, rent or in the auctions

I've got the same trouble with the Speedster but it is on the Car Collection as exclusive content (level 3). Macan is in a car pack and the 911 is also exclusive content but I appear to have unlocked that one.

This list is out of date! I just finished the cheevo and, required 33 cars. As for 20-30 minutes, f**ing stupid!

I'd like to point out one thing. In Polish version of FM7 achievement description has Ferrari instead of Porsche. Of course requirements are the same. I hope it is the problem only here but I thought it might be good idea to show this for fellow Poles who might be looking for an answer why they didn't get an achievement.

Spent some time trying this last night and it didn't happen for me. I've noticed the achivement tracker isn't showing any progress at all which is weird. Any ideas why that might be? Does it take some time for the True Achievements website to be able to access my progress?

I've been stuck at 96% for weeks... I've raced each Porsche minimum 3 times by now.

Wtf.

I have the same Problem, stuck at 96%

same problem. 96%

L.E>I found missing car: 1960 718 RS 60

I finally got this one to pop today. (Thanks for the car list!)

I was stuck at 93% for a long time and had raced every car on the list. I had a couple cars that showed 1 race and no victories or podiums in Car History. I raced those on the drag strip and it gave me credit for each.

I don't have anything concrete beyond that, but if you're having trouble, maybe give that a try.

Also, the Save Settings for drag racing with Porsche as the model would not reload properly for me. It reset to the car class quite frequently for me. And when I loaded it, it would have "Any" under the Make portion. Irritating. Why have saves if it doesn't work for ALL settings?

Thanks for all the posts helping with this one.

I started with the oldest and after the 2017 #2 Team 919 Hybrid i got the achievement.

I was only missing the "2015 #19 Porsche Team 919 Hybrid" and redid the whole list to add all cars to xbltracker.com

https://xbltracker.com/tracker/game/1999574456

This is stuck at 10% for me despite racing a bunch of cars.

Drag doesn't work anymore, confirmed.

Did work for me.

So Drag is tracking for me.. I raced every one on the list and it tracked up to where I need one more yet I raced the entire list... odd

Still works May 29, 2020!
Thank You!

I was able to unlock the achievement from start to finish on Xbox One on 6/17/2020

It worked fine using drag race.
Just unlocked it.

Worked fine on Xbox One.

The only issue I had was with the 959! Tried to use the car I own but it was illegal for the lobby due to the upgrades installed when I bought the car! Tried using the auto tune to return the car to stock and the game doesn't register it! It continually says your car is illegal so your best option is to use rentals for this cheevo

Perfect cheers! 🙌

Perfect solution +1

+1

Worked perfectly. +1

Right on. +1

Thanks Fejer for the link to that tracking site. Was able to easily see what porsche cars I was missing to do this. OP should add the link to the solution main post. But it's still a thumbs up solution as a whole for me.

Holy moly, that tracking site is GOD TIER. I would've never known which cars I was missing without going through the whole list again. I agree, that link should be included in the solution!

Test drive is the way to go. Thanks for the list.

@Secrecy 30, the 2008 RS Spyder Evo is the correct one.

Don't know how you've managed this with 29 cars.ive found 33,raced them all and it still didn't unlock.guttes,an hour il never get back

Got the ´08 Spyder Evo also and raced with all the listed cars but the disappeared #7 and no achievement

Perfect guide, +1

Fejer, thank you so much for adding the cars to XBLtracker.com
I had never heard of that site but how it's integrated with our gamertags is absolutely fascinating! It showed me exactly which car I still needed for the achievement, thank you!!!

if you're in a rush and don't mind much about the race rewards, you can ignore the light at the start of the drag race and it will still count as long as you reach the finish line

@ ICE Faux Pirate Thumbs up, XBLtracker.com was very helpful!

Great solution. And huge thanks to Fejer for the link!

Recently I drive FM7 before Motorsport came. And this help me to finish this achievement. Do drag and u are fast finish.

Use XBLtracker.com to keep an eye on what Porsche cars you’ve already used.

Excellent website, helped me a lot

Thanks

I have compiled a list of all 29 Porsche's that you need for the achievement.

What I usually do is create a Google Doc (I pulled this list from my own) and "strike-through" anything that I know I have driven (I watch the achievement tracker after the race to make sure my progress is accounted for.)

For anyone having difficulties obtaining this. Just systematically go down the list and make sure you are getting credit for each one, are not skipping any, and are marking off ones as complete when you do get the credit.

PS. Thanks OP for the reminder about drag races. I am about 25% into this achievement now, and plan on switching to drags from the Lime Rock circuit I was using. Should help speed things up. You get an upvote for that.

ONE THING I SHOULD MENTION:

When "restarting" post-race, does anyone get a pop-up stating that you have to change your car because restrictions have changed? They don't seem to ACTUALLY change, however. Go through the setup > race setup menu - make sure rules, advanced rules, and car restrictions are all open/any.

If anyone has any feedback for my list, let me know and I will update it. OP if you find my feedback helpful, feel free to give me a mention. Feel free to give me thumbs up if you find this useful. Thanks.

I've driven 30/30 but it won't pop. I have a 2017 #92 Porsche GT Team 911 RSR as the extra.

Any ideas?

Worked first time.

Went through the list, some didnt register but im guessing thats because ive already drove them in game.

Can confirm that you dont have to drive the 2016 911 GT3 RS.

I was briefly stuck at 96% too. I had to race a car again. I know this won;t help anyone already stuck but, for those just starting, here's what I did.

I copied the list of cars and went through each one making a note of the ones that caused the achievement tracker to rise...also noting which ones didn't. I was at 17% when I started meaning I had already done 5 cars. When I got stuck at 96% I went back through the ones that hadn't caused a rise. There was one I had definitely expected to cause a rise (as I didn't remember ever racing it before) that didn't change the tracker so this was the fist one I retried and it popped straight after the second time I raced it.

I don't know if the achievement is buggy or certain cars, but the car I had to re-race was
2016 Cayman GT4

I dont know what is happening, but 2008 #7 Penske Racing RS Spyder Evo is not available at my game, just the normal ´08 RS Spyder Evo. Not available at auction house neither. Any reason for that?

Brilliant help that website, thanks

This one works perfectly and is also the quickest way to get the achievement done. Thank you.

Dont think this method works anymore.

Just did it and achivement dident pop.

Maybe there has been a patch or fix for it.

Still works, although I was doing the test drives it on a free play 1 lap race.

15-20 minutes, my ass!!!

Nice one Buddy got it in about 15 mins - just a tip don't be fooled by the two Porsche Carreras - one is 2003 and the other is 1973 ...

Great solution! Should be #1.

top solution with test drive - thank you!

Best method!!

Awesome solution. Worked first try. Make sure you go through them in order without skipping, I didn’t use any of my own cars, I just went through all rental cars one by one

Doesn't work.

Drag or drift doesn't work anymore, confirmed.

Worked like a charm :D .

Worked fine on Windows 10

Drag absolutely still works on Xbox as of today.

Worked perfectly - just did it in 20mins.

This is an amazing site. Not only for this game, but for many others. Thank you!!!

Not tracking for me.

Drag doesn't work anymore, confirmed.

Drag might not work but upvoted for the link to that fantastic site.

Drag worked for me today

Not sure about you guys, but https://xbltracker.com does not work for me anymore.

Yup, the website doesn't work and his twitter account has been deleted. That sucks.

The site seems to be back up

Tracker is perfect. Showed me the last 4 I was missing.

Congrats CasperTC to the achievement. Happy that the guide was helpful.

@Destro WOD: You're welcome. That website https://xbltracker.com is quite helpful for certain achievements, unfortunately it doesn't contain all games and achievements with such a setup (would have helped me a lot with certain achievements in Sea of Thieves).

My best guess for the reason for the different naming in the vehicle could be maybe some region-based translation. As mentioned in the guide, I took the list from the guide provided by Shadow Shifter & sirre0812.
