There are 4 tours to do and you need to be 1st in every single race, this shouldn't be too hard since they are pretty easy. You will also have some "Race Specific" achievements to do which can be done along the way in your Showdown Tour or after the fact. Be mindful that you also need to buy and upgrade all the cars which is normally not doable in a single playthrough but there is a way to do it. Read "Money" section for more details.

The Joyride section consists of 2 locations with 75 missions each and 100 hidden packages all together. Missions will be straight forward to do and for hidden packages you can use the provided video guide to help you find them.

This would be your most time consuming part but there is a cheat you could do to speed it up. You need to reach level 30 online but since nobody is playing multiplayer your only option to get there is through private matches. I'm sure you'll be able to find somebody to help you over in Discussions. There is a way to get to level 30 quick which involves a lvl 29 save file which you can access here, this save file also has enough money to get Max Power achievement. Keep in mind that you will still need a buddy to get the rest of the online achievements. You will also need to be leveling up a few levels to get enough money for that Showdown Showroom.

All of these achievements are a part of a normal Showdown playthrough. You need to finish all 4 tours with gold in every event and you will get all of the achievements below.

Crash-Bang-Wallop - What a Video
View a Crashback replay


This achievement is the only one here you can easily miss. When you hit an opponent really hard a little icon will appear in the bottom left corner of the screen, press to view the Crashback replay.

Some of these you will get in your normal playtrough. But for most of them, you will have to replay some races and do specific things.

Ego Boost
Win a Race-Off event without boosting


Easiest on the first race in Showdown Tour. Just don't use the boost.

Hard Charger
Use a full tank of boost in one go without crashing in a Race-Off event


Same first race as Ego Boost. Use your boost when you get to the long straight road. Make sure your boost is full and use it up completely without crashing.

Zero to Hero
Dominate all sectors during the final lap in a round of a Domination event


Start a Domination event and make sure you do not dominate any sectors until the final lap. Then go crazy and dominate all sectors for the achievement.

Burst the Bubble
Be in 1st place during each elimination period in an Eliminator event


Get in to Eliminator race and be the 1st throughout the whole match. The tricky part is getting there before the first elimination, but once you get past that the rest should be easy.

Survivor
Survive for at least 2 minutes in a Hard Target event


Rust in Pieces
Wreck 20 vehicles in the Lafayette Eulogy


Lafayette Eulogy is a car that you can unlock early on in the game. Once you buy it, wreck 20 vehicles over the course of your playthrough.

Wrecker
Achieve a 5x Wrecking Streak in Rampage


Select a Rampage event and wreck 5 cars in a row without getting wrecked yourself. A good tactic to use is to let other cars do the work for you while you swoop in for the kill.

Hitman
Achieve all hit types in Rampage


You don't have to get these in one go. There are 11 of them: T-Bone, Shunt, Side Swipe, Head On, Bash, Slam, Strike, Barge, Low Blow, Headshot & Overhead. You should be able to get all but the last 3 in your normal playthrough. For the Low Blow, Headshot & Overhead, you can start a Split Screen event if you have a controller and set up the cars until you get them.
Here is a useful video on how to do it:

Comeback King
Be in last place and then earn a podium during double points in a Rampage event in the Showdown Tour

In a rampage event, you must be in the last place during the whole match and then when the double points start in the final 30 seconds, you must score enough points to finish in the top 3. Make sure you stay close to 7th place during the whole match, when the final 30 seconds start look for badly damaged vehicles and finish them off. Hitting cars in the side does the most damage.

Balletic
Complete a clean run in a Head 2 Head event


Pick one of the first Head 2 Head runs and make sure you complete it without bumping into anything.

Stylin' and Profilin'
Score 300,000 points in a Trick Rush event in the Showdown Tour


Some tips for this: get all the smasher blocks first to get x2 or x3 multiplayer and then move onto your drifts, jumps and donuts. Try not to do the same trick too many times in a row since you get less points.

There are 2 compounds to do here with 75 missions each and 100 hidden packages all together. Doing all the missions is straight forward and for the hidden packages you can attempt to find them yourself or you can use a video guide which I included.

Hoonigan
Complete all Joyride Missions in both locations


Hoonzilla
Complete 100% of the Yokohama Compound Missions


Dock Worker
Complete 50% of the Yokohama Compound Missions


Mmmm Donuts!
Complete the Donut King Mission in the Yokohama Construction Site area


Daredevil

London Calling
Complete 50% of the Battersea Compound Missions

There is a total of 60 packages in Yokohama and 40 packages in Battersea.

You will need to find somebody to help you with these. Luckily there are still people going for the achievements so you will able to find some groups by visiting the Discussions page.

Showdown Superstar

This will be the most time consuming achievement to get, especially with multiplayer being dead. You can find somebody that also needs this and help each other out in private matches.
BUT there is a way to cheat this which involves a lvl 29 save file, the guide to do this is here.

Rising Star
Reach Fanbase Level 20 Online


Household Name
Reach Fanbase Level 10 Online



Running the Show
Dominate a friend in Challenge mode


You need to have 10 wins over your one friend in challenges. Easy way to do this is send 10 challenges to a friend, he then accepts the challenges to start the races one by one, and when the race starts quit the challenge. It will count as a failed attempt and a challenge victory for you.

Beat it!
Accept and beat a friend's Challenge


Get a friend to send you a challenge you can easily beat. You have 3 attempts.

No Turning Back
Send a Challenge to a friend

You will not be able to unlock and upgrade all the cars from a single playthrough. If you used a legit method to getting to level 30 online you should have enough money to get these achievements. But if you used a lvl 29 cheat, you will have enough money on that account to get the Max Power achievement. So you do not need to focus on upgrading vehicles but instead save the money so you are able to buy all the vehicles for Showdown Showroom.

Money Maker
Earn a total of $1,000,000


When you finish all the races in 1st place, you will still be $20,000 short of that 1 million mark. To get the remaining money you can simply level up twice in online mode, which nets you $10,000 per level. Or you could send 20 challenges to a friend, where every win nets you $1,000.

Max Power
Fully upgrade all vehicles


This achievement can be obtained by replacing a save file found in this guide. This account has more than enough money to upgrade all the cars. Otherwise, you will need to level up a lot of online levels to be able to have enough money.

Showdown Showroom
Own every vehicle in the game


Depending on how much money you spent on upgrading vehicles throughout your playthrough, you will still most probably need some extra money to be able to buy all the vehicles. Each level in online mode will net you $10,000, so find a group in Discussions and level up.
I personally needed $50,000 so I leveled up 5 times.

Gonna Need a Bigger Garage
Own 15 vehicles


You've Created a Monster
