Hello Everyone! This guide is here to help you with getting all 100% achievements in Project CARS.
Thankfully, the achievements are colour coded, and I've based these into categories.

Good Luck!

Career Achievements are fairly straight forward. Play the career mode and you will get them. These Achievements take the longest but are some of the simplest and most straightforward. To make them even easier, you can set the AI difficulty to 0% and win easily.

One More For The Road
Description:Earned all other Trophies/Achievements.

How to: This will be the last achievement you will get. It will trigger when you have gotten all the other Achievements.



Conquered.All.Races.Seriously.
Description:Won every race in a Career Championship.

How to:Win every race in a career championship! This includes top place in qualifying, Practice doesn't matter.



Meticulous
Description:Completed every Practice, Qualifying, and Race session in every round in a Career Championship.

How to:Similar to the one above, But you do not need to win for this, just participate. Participate in all 3 "Practice, Qualifying and Main Race" rounds in a championship. Easy 2 achievements. This Cannot be done in Karts and other series that don't host practice! I recommend GT3 or LMP1.



Twerkin'
Description:Win your first Accolade.

How to:This is unmissable as you go about the Career. There are 3 tiers of Accolades – Gold, Silver and Bronze. Bronze are the most common, Silver less, and Gold are the rarest, only given for the main Championship series and very special invitation events such as Le Mans 24hr. This Achievement requires you to attain 1, your first. By purely just playing the game and doing Optional race series and "invitations" you will get this achievement quickly. "Taylor would be proud" is the same principle but with 22 accolades.

Defending Champ
Description:Defend a Career Championship for three consecutive years.

How to:I recommend doing this achievement after you have done "zero to hero". Consider this to be one of your last achievements. This is an achievement tailor made for fans of a certain class, but there's a catch – it only triggers for championships in Tier 2 and up. There's just four of them – Both LMP series, Formula A and Endurance Series. However, within Endurance series, you can pick any class you want, even different ones.

Fully Loaded
Description:Sign 8 Endorsement deals.

How to:To sign an "Endorsement deal" you first need to have one GOLD Accolade. See "Twerkin'" on how to gain Gold Accolades. For all 8 deals to be signed you need a total of 16 Gold accolades. This will take some time in its own form.



Zero to Hero
Description:Win the LMP1 World Championship within ten seasons.

How to:This is the Main goal of Career mode. A non missable but the longer you leave this achievement the harder it gets! Do this one first!
This achievement requires you to climb the ranks from Kart One to LMP1. You will need to start your career in Tier 8 which is 125CC Karts, and complete (and preferably win) championships, in order to then sign a contract with a better league. You have ten years to complete eight ranks, so you have two strikes where you may not progress – or even more if you skip tiers. You have multiple options when choosing a team, so make sure it's in a series that's a higher tier than your current one!



Taylor Would Be Proud
Description:Win 22 Accolades.

How to:See Achievement "Twerkin'" for more info. You need to get 22 accolades out of the 112. 20 gold, 52 Silver and 40 Bronze. It does not need to be 22 gold or 22 silver, It may be mixed. This is a easy achievement that will be done in time of playing the game.



Double Rainbow
Description:Win the same Career Championship two years consecutively.

How to:Same deal as Defending Champ, but only two years instead of three and doesn't have a class restriction.


Hall Of Fame
Description:Complete three Historic Goals and become a racing legend!

How to:"Zero to Hero", "Defending Champ" and "Triple Crown" are the three Historic Goals. Each of them has a respective achievement, see their sections for the information on them.



MailBox Full
Description:Receive more than 500 messages from your fans.

How to:The more you play the more Messages you get! Just keep racing and playing (And winning) and you will soon have 500 Messages.


No "I" In Team
Description:Win a Team Championship two years consecutively.

How to:Win a team based tier two years in a row. Similar to double rainbow achievement, But you need to do this in a team based championship. Karts don't have teammates, GT3 and LMP1 do! I recommend doing LMP1 for 2 year running as its the least time consuming.



Triple Crown
Description:Win three Career Championships in three different motorsport disciplines.

How to:This is easily done, you need to win three championships in different motorsport series, which you'll do while climbing ranks, but only championships from tiers 3 and up count! Both LMPs will work, as will Prototype 2, Endurance series, GT3, and Formulas A and B.




VIP
Description:Receive 12 Invitations.

How to:From winning and setting good times in qualifying, and completing other objectives (such as completing a certain total number of laps) you will get Invitations in mail, and the events will be posted on your calendar. Keep racing to your best and you will get 12 invitations for Optional Race series and events.

Multiplayer Achievements are a little trickier. Easy if you have a friend to help.

Player 1 Versus The World
Description:Enter and complete more than 25 Online races.

How to:This does not mean "win". Just simply finish. So DNF or DQ do not count. This is easily done with a friend or joining a random lobby.


Pristine Paintwork
Description:Complete more than 3 Online races with 50% of them avoiding a major collision.

How to:Again you do not need to win the race for the achievement. Simple finish without any crashes, or very minimal if so. Again Easier with a friend.


Pentapodia
Description:Finish on the podium more than 50 times in an Online Public race.

How to: Come in 3rd or better for over 50 races for this achievement. Easy with a friend, If not find quiet lobbies or practice until you are good.


Speed Racer
Description:Set a Pole Position time in an Online Public qualifying session.

How to:This can be done by setting a fast lap time on a online public race. Easy with a friend, otherwise you will need the edge on the drivers in the game.


Clean As A Whistle
Description:Win three Online Public races in a row without being involved in a major collision.

How to:Avoid all crashing at all times, and win three online public races in a row. Easier in a friend lobby, but it has to be open to join for others.


I Am The 5%
Description:Won an Online Public race using manual gears, and no driving aids, from cockpit view.

How to: Disable all your assists in settings and set Cockpit view in manual gears. This can be done in a race where the host forces all these options.

Solo Achievements are the easiest of them all. They can all be done from quick race and free practice in the menu. These can also be achieved online and in Career. Some are harder than others. Time to completion 40 hours.

Gladiator
Description:Win a Quick Race Weekend with Full Damage, Mechanical Failures, and Tire Wear (must be 5+ laps).

How to:Go into quick race choose Karts and any Kart track. Set all the assists above.Full damage, Mechanical failures and tyre wear. I would also advise Fuel wear on real. Do 6 Laps and come first. You can set the AI difficulty to be low and this will make it easier.


Eastbound & Down
Description:Run the California Highway in under 9 mins in a US car.

How to:Choose the "Ford mustang Boss 301R1" And Set the track to California Highway full, Assists can be on. I made a few errors while doing my run. This can be done fairly easy with a bit of practice.
Here is a video of my attempt , As you can see I had a whole minute left.


Keep Calm And Race On
Description:Crash on or before the first corner then go on to win the race.

How to:Damage needs to be set to Performance impacting (Not full) You need to have a crash, nothing major . And Win the race. I recommend Monza short in a BMW M1, Set AI to lowest difficulty, crash on first corner at around 50 MPH Continue the race, With it being a bit harder to drive its still possible to win with the ai being so idiotic and the track being easy.


Emergency Stop
Description:Brake to a standstill from 100-0 km/h within 2 secs.

How to:Go on the Nurburgring nordschleife go to the long straight in a formula A , Drive to 100 km/h and hit the brakes. If you are struggling with it, increase brake pressure and lower brake duct.


Pit Boss
Description:Create and save a Pit Strategy.

How to:Go into pits "Pit Strategy" and save. It will auto name to the cars name and the achievement will unlock.


Requesting Flyby
Description:Enter and exit the pit lane without losing a position (cannot be in last place)

How to:This requires a little amount of skill. Set AI to 0% difficulty, Choose track : Road america. And a Car you enjoy driving. Something fast is usually better to do this on. Set laps to 20 or so. Do enough laps until you have overlapped everyone, Go straight into pits for fresh tyres and fuel. Leave pits and you should have the achievement. Another way is to time how long it takes for the pitstop on a race, gain a lead that is around that same amount of time and a bit more. This should be achievable with long races with easier AI. Usual pit time is from 5 seconds -22 seconds. Depending on fuel, tyres, fixing and track.


A Day In The Life
Description:Complete a 24 hour race using only realtime progression (and why not stream it?!)

How to:Since the new update (6.0) You can do this on multiplayer. The other way of doing this would have been from LMP1 after enough seasons you have the option to do a 24 hour race . Make sure your time is set to 100% real time otherwise it will be a 10 minute race. This seems horrible to do as staying awake and leaving your system on for 24 hours for 1 achievement may seem mad to some.
Fret not! There are ways to make it easier.

First you need to go into the race. You do not need to "Win" it but just complete it. Ways of winning are harder, Race 6 hours, Pause and race another 6 hours. But if you want to just complete it, which is what this achievement requires , Then simply Start the 24 hour race. Do 2 laps. Leave it running but do not pause,close or flip out. Come back in 23 hours and 50 mins time. Wait for the finish and go do your last lap. If you miss the last lap (End race timer) you will be DQ and you will not get it. Set a alarm if you need to.


Reversa Corsa
Description:Complete a Quick Race Weekend lap of Azure Circuit in reverse from cockpit view without collisions.

How to:This was the stupidest achievement I have done for a while. Get a 250CC Kart and go on the track Azure circuit. Never press the Accelerator, nor crash!
Start the race (make sure no AI) And reverse, Do a U-turn and start the track in reverse. Look back as this will help you see where you are going, continue to reverse all the way round. Go past the finish line and get the achievement! Make sure its on 1 lap, No AI and damage is off. Force cockpit view aswell! Go slower than you usually would to be extra safe.


No Roads Needed
Description:Get all four wheels in the air for more than 0.88 secs.

How to:Get the Lykan Hypersport, go to California Highway Reverse. Floor the first part and in one corner, The first tight one, You can get some air time. Just go flat out over it and you will get the achievement.

Solo Continued
Sunday Driver
Description:Drive the speed limit (50 km/h) in an Italian car and appreciate the Azure coastal scenery.

How to:This one took some time, 30 Mins to close. It's a easy achievement but you need to make sure you don't go too fast! and the italian cars in this game are , Well very fast!
Pagani Zonda roadster was my car of choice, the track needs to be azure coast full.
Depending if you are imperial or metric , the speed reading might be harder. Here is a video of my run on Azure coast. As you can see the Accel on this car is quick and so it was a pain. 50km/h is 31Mph to be safe do 25 Mph or 40Km/h as 1 Mph or km/h over limit might fail you from the achievement.


Grand Chelem
Description:Get pole position in qualifying, fastest lap in the race and win whilst leading every lap.

How to:This was harder than I thought. Get a fast car and a short track to do this on. Make a qualifying and a main race with 2 laps. Set the fastest lap in qualifying, That should be easy. When starting the race make absolute sure he never ever gets ahead of you. Win race and set the fastest laps.
The only error in this is that if he gets in front or goes past starting line .0001 before you, the achievement won't trigger.


Consistency Is King
Description:Perform 3 consecutive laps within 0.1 sec of each other.

How to: If you are a League racer and you are great at consistency, then this will be a breeze. Otherwise this may be harder. Go on karts and choose Summerton (any layout) Do 8-10 laps to have some breathing room. This should pop up if you can get all 3 laps within 0.1 sec of each other. Otherwise keep practicing.


On Your Left
Description:Lap an opponent in a race.

How to:Easily done on any long lapped race. Just keep driving well and setting good lap times and before you know it you will have caught the pack up.Overtake one of them and this will pop up!


My Little Friend
Description:Overtake a car using KERS.

How to: KERS is limited to Formula A only. Do a race with that but hold down the KERS key while overtaking. KERS gives you a extra 28bhp. its set by default to "B" on Xbox controllers.


Ready To Pounce
Description: Have a reaction time of less than 0.2 secs off the starting grid.

How to:Make sure you are not red lining but close to it. When it goes green, within 0.2 of a second you need to launch your car. This may take a few tries but isn't hard.


Half Racer, Half Demon
Description:Drive faster than 333 km/h for over 6.66 consecutive secs.

How to:You need a track with a long straight, Nurburgring Nordschleife is a good one. Choose a fast car. The McLaren F1 is a great choice, so is Formula A with the right gears. 333 Km/h is 207Mph . You need to maintain the speed for 6.6 seconds.


Credit Where Credit's Due
Description:Crash into the AI counterpart of an SMS employee.

How to: Make a race with as many AI as possible, put yourself in the back, jump the start and get crashing. Within several tries, you'll hit one that's named after a dev.


Do You Smell Somethin'?
Description:Make your brakes reach a temperature of 1000.

How to: All 4 brakes need to be at 1000F/537C. Go into tuning setup and set brake duct to 0% – this way the brakes will take forever and a day to cool. Now go full speed and slam the brakes on, and do this until the brakes reach temp. Took me until 1100F to trigger the achievement.

There are only 3 of these.These are by far the easiest and most fun.

Exorcist
Description:Beat a Ghost from the Time Trial Leaderboards.

How to:Find someone really slow on the leaderboards. Set as a ghost and beat it.


Lap Time Wizard
Description:Set a time at 50 locations (variations and reverse layouts not necessary).

How to:Go to the "Leaderboards" Section on Race central and set a lap on all tracks. This is easily done with a FA for the majority and a Kart for the others. Do from top to bottom to save confusion.


Community Ambassador
Description:Participate in 20 Driver Network Community Events.

How to:In the Race central page, there is a Community section with the daily/weekly/monthly events that SMS host. Enter 20 of these and it will pop up. You must set a lap time for it to count and this may take a while, but it's rather straightforward.

These achievements are easy. Similar to the "solo" achievements. These are more to do with your overall profile.Some of them are time consuming, But nothing major.

To Affinity & Beyond
Description:Have an Affinity greater than 50% in all car classes.

How to:Keep winning in every car class you drive. This can be done in quick race. Make sure the win/lose ratio is 50% or higher.

Petrolicious Love
Description:Win more than 50 events with your Signature Car.

How to:This will gather over time. A Signature car is decided based on how many miles you have driven with it. Just win 50 Races in it and this will pop up. You will need to win 51 Races for this to trigger. Doing this in a Kart race online is a fast method, and you will also unlock "Pentapodia" Achievement.

Thank you!
Thank you For reading my guide.I hoped it helped you!
Please remember to Rate up if it has helped you out! Thanks.

Thanks to Party Magician for Overhaul check.


Update
Just got my 8th Sponsor in the game and its completed all but 1 in the "Hall of Fame" Which was Get all invites.. And I got the Final Achievement. Conclusion to that is you don't need everything in the Hall of fame for it to trigger. If you get all the Achievement then head for the last sponsor you should get 100%.
