Bonus cars
Look for red circles that appear on various levels. Place your car on the circle until a gurgling sound is heard to unlock a new car. Some of the circles can be found at the following locations:
London
Near the starting point is a ramp on one of the buildings. This leads to the circle on a roof.
Go near the center of the map. The circle is inside the Parliament building (block building with pillars on the outside). Drive through the window to get inside.
Find the strange turn near the Parliament building. Climb up a ramp, then jump to the left or the right, but do not fall off. Turn around to find the circle.
New York
Go near the park above the big tunnel. The circle is on top of a roof that you need to jump to reach.
Go near the aircraft carrier. The circle is inside the second story of a building that you need to jump to enter.
Drive On USS Enterprise
Choose the NewYork map, go forward one block, take a right, take the second left, go on block, take a soft right. Go as fast can for one block. Then, go straight through the stoplight, into the building that sits beside the water, up the ramp, and into the opening in the side of the aircraft carrier. A ramp at the far end of the hangar leads to the top of the ship.
Get Nitrous Boosts
In order to geed the Nitrous boosts, you have to get the third level of a car. Once you have the third level car, for instance the Last Truck, go into a race. Then, click the horn button. You should hear a WHOOSH. (You get a limited supply, so use it wisely; around 5) This really will help you break those neck-and-neck races on the straightaways
How to get on the ship
In New York, there is a blue spot on one of the edges of the map. Go on the curve road and drive at around 100mph. Look for the blue spot, there will be a hole in a building and that's where you have to go through to get on the ship.
