Easy money in Crash mode
When you get to the main menu, go to "Single Event" and "Crash Mode". Select "Junction 19", "Tuk Down", and "Muscle type 1" as your car. Boost start at the beginning. Drift and collect either the gold or silver (it is possible to collect both of them). Smash through the boxes avoiding the wall, into the boost and up evenly on the jump, avoiding the heart-breaker to your right. Collect the x2 multiplier and after touch, making sure you try to land evenly without hitting any boxes. Slide into the Crashbreaker, and get to the x4 multiplier past the buses in aftertouch. If you get knocked out of the way by the buses, wait until you stop and press Crashbreaker. Aim in the direction of the x4 multiplier. If you miss, you always have the x2 as a fail safe. It is possible to get $1,500,000 to $1,750,000. Repeat this, and do not select "Retry"; as all the money adds up to the total score.
Go to junction titled "On-Rampage". The largest car you have will work best. Getting the boost start at the beginning is not required, but it does help. It is possible grab the silver or bronze pick-ups, then pick up the 4x multiplier and hit the car that is closest to the yellow strip on the road in the oncoming lanes. Use aftertouch to try to stay in the spot that you hit that car. Wait until there are two or three seconds remaining, then use your Crashbreaker to explode. Try to take out the gas tankers with the explosion. It is possible to get $1.8 million to $2.5 million.
When you have crashed into a Crashbreaker icon, try using aftertouch to launch your self through the air and hit an oil tanker. Note: This is difficult; you need to know where they come from in the level. Hopefully your Crashbreaker meter should have gone down. Press R2 to blow yourself up and the oil tanker. This will result in $99,990 for the oil tanker, and if you can get the 4x multiplier, you will have stacks.
Go to Junction 100 (a.k.a. "Crashed Out") and choose "Fire truck" as your vehicle. Get the boost start at the beginning and grab the boost pick-up. Steer clear of all three ramps and keep going the wrong way. Eventually you will see two semi-trucks heading toward you. Try to hit the one on the right. Use aftertouch and go to the other side of the freeway (try not to go downhill). When you use Crashbreaker you will make all three tankers explode. The exploded tankers are worth almost $100,000. You should get more then $400,000.
Go to Crash Junction #40 (or "Drive Angry") in Single Event mode. Crash and choose one of the heavyweights (for example, the Firetruck). It should work with anything with at least five bars of weight. Start and get the boost. Avoid the walls and heartbreaker and slam into the semi. You should get a Crashbreaker almost immediately. Use it to drive down the other dirt path and get the 4X multiplier. If you hit it correctly, you should get at least $900,000 and also you may see small cars dropping out of the sky as a result of the Crashbreaker.
Easy takedown
As soon as any race begins, immediately get behind the nearest opponent and hold Boost. You will start getting "Tailgating" points and will receive a short boost. Use this boost to quickly slam your opponent. This will result in a takedown about 90% of the time and will immediately fill your entire boost bar.
When in race or takedown events, get behind your rival's car, then boost. This should take them out. If not, slam into them (while using boost) on the back corners of the car. This should take them out against a wall.
Go to road rage in single player mode. Pick USA Silverlake southbound as the track. Choose Assassin Super as your car. Throttle it to the other drivers. Start pounding them and keep Boost held. Do not bother to slow down for the corners, just slide around them. Your rivals will do the same. Keep pushing up the back of them, and after a moment they will go flying and you will get a takedown. You can get more than 30 takedowns by doing this.
To easily take a car down, go behind it. Then boost behind it and shunt it. It will immediately be taken out.
Euro-circuit Racer
Unlock all takedown trophies.
Extra boost
On crash courses, use the Right Analog-stick to point up on the countdown. On each second, rotate it in a circle. On the last second, rotate it around twice to get an extra shot of boost.
Get three takedowns so that you have a good amount of boost in your boost bar. Drive in the oncoming lane with your boost. Your boost will not go down and become infinite until you crash or go out of the oncoming traffic. Note: This works even better in Burning Lap, Preview Lap, and Special Event modes. You will actually start gaining boost when this is done in those events.
In Crash mode, press L1 and R1 repeatedly during the countdown. Sometimes you will start with about five seconds of boost.
Fire Truck
Unlock all crash headlines in world tour mode.
Getting into big corners
When at full speed (outside), hold Boost so that you will take the corner from the outside. Yyou will grind one of your sides for the entire time. When drifting with boost (cutting), start drifting and turn your car so you will be facing the one third of the road (about 35 degrees from the edge of road) and press Boost. You will achieve a drift bonus and get the corner really fast. When drifting (cutting), approach into the corner, drift, and make sure you stay on road for faster speed. You will achieve drift. When slowing down (inside), release Gas and take the corner slowly from the inside.
