Cars that can reach this speed with no upgrades are:
- Bugatti Veyron Super Sport
- Koenigsegg Agera R
- Pagani Huayra
- Lamborghini Aventador
- Ford GT
- SRT Viper GTS
- Chevrolet Corvette ZR1
- McLaren MP4-12C
- Lexus LFA
- Bentley Continental Supersports
- Lamborghini Gallardo
The top speed on these cars are in descending order, so obviously it is easiest to do it in the Bugatti or Koeniggsegg.
To do this easily I would do some of the races with one of the listed cars to get some upgrades. The most important upgrades for this are Nitrous, Track Tires and Long Gears. Once you have these just drive round on the Interstate road, there are plenty of speed cameras to drive through.
The way I did it was when I found a good speed camera I took a long run up and got the achievement very easily.
