Ik There r Nero and Overdrive drivers here. So I went out and did some research and i figured out that Overdrive is faster but it is just very slightly faster than Nero. Now the thing is Nero has better accel and that is why the Nero was winning races and everyone thought it was faster. It turned out ever time i raced both it seemed at the end the Overdrive was gaining so i did a long-stripped drag race and sure enough the Overdrive caught up to the Nero and would've passed if buddy knew how to drive a car. Lastly with the boost Overdrive is fastest because the boost eliminates acceleration which the Nero accels in so if Overdrive has the initial top speed of the 2 then it would technically be the fastest car in mad city boom just closed year long dispute.
