For Week 7, there are three challenges involving the vehicle Whiplash, and finding the car will be the hardest thing you'll have to do, and oddly that isn't even a quest!
Two of the three challenges you can do pretty much together, the third you cannot. The first is to drive the Whiplash through the Storm, and the second is to reach top speed with the Whiplash. Both are pretty self-explanatory but finding the vehicle, as we said above, is the hardest thing you have to accomplish.
The ideal place to locate one is Lazy Lake, as there is a high chance of one spawning there. If not, Retail Row or Believer Beach is your next place to get one.
To reach the top speed, make sure you've got a full tank, find a long stretch of road, put the pedal to the metal, and boost as long as possible. Even better if the road you are driving is going into the storm, as that's two challenges with one car.
