Need for Speed Payback | 240 mph Hyperspeed Achievement / Trophy Guide.
To reach the top speed of 240 mph in Need for Speed Payback you need to be near the end of the main story and unlock cars that can potentially be upgraded to 399.
I chose the Koenigsegg, which is quite expensive but lets you reach the 240 mph without any upgrades. There’s a lot of other cars that can reach that top speed with speed updates.
