The Ferrari 458 Italia did not trap 134 mph in M/T's conducted test. Here's why. Let me start off with a quote from Wikipedia regarding the entry of a LaFerrari in their 1/4-mile article:
Motor Trend´s LaFerrari report published a 9.7 second 1/4 mile after the 9.9 second result was rewritten to account for weather. Motor Trend stated: "Fiorano's downhill front straight was the only place we were allowed to do acceleration runs, and we couldn't run backward for a two-way average. The data shows the fastest quarter-mile run declining by 18.2 feet from start to finish, or 1.4%. For reference, the National Hot Rod Association allows a 1.0 percent maximum grade over the course of a quarter mile.
Noting that this "MIRA" track was also used by Ferrari itself, with mention of wind being used as an "opportunity" by Motor Trend, I'm not obligated to take that 134mph trap speed seriously; especially if a Huracan or an Aventador traps 135mph.
The dual-clutch naturally-aspirated Ferrari also couldn't be equally as quick, let alone quicker from 120-140 mph than from 100-120 mph in a regular straight line.
0-60mph 3.0sec + 0.3 for rollout = 3.3; that means 100km/h in 3.42-3.46s, but let's use 3.45
0-100mph 6.4 + 0.3 = 6.7
0-120mph 8.9 + 0.3 = 9.2
0-140mph 12.2 + 0.3 = 12.5
100-120mph from 6.7 to 9.2 gives a ratio of almost 1.75, while 120-140mph from 9.2 to 12.5 gives a ratio of nearly 2.
(100/120)^1.73920x9.2
(120/140)^1.98847x12.5
Anywhere from 9.78 to 9.86s from 0-200km/h, but we'll use 9.8s.
3.45+9.8/(3.45+9.8)x10 = 10.846s from 0-380m (this is the Quattroruote/DragTimes/NHRA version of the 400m run)
3.45+9.8/(3.45+9.8)x10.375 = 11.124s from 0-400m (the true 400m); if you subtract for rollout, that 400m time becomes 10.824s.
Nonetheless, the quarter-mile time posted in M/T's datasheet is accurate for an American test. But it sure won't replicate that 134mph trap speed! Actually, the ratio should be much higher in a small-displacement, high-revving n/a car.
(134.0/120)^(1.73920/0.75)x9.2 = 11.9s (11.6s with rollout)
(132.0/120)^(1.73920/0.75)x9.2 = 11.5s (11.2s with rollout)
(130.6/120)^(1.73920/0.75)x9.2 = 11.2s (10.9s with rollout)
Even at the 1366ft line the car will be trapping 132.X mph at best. The 11.2sec 1/4-mile time is possible only with the secret launch control, but it'll void the car's warranty even worse than the Dodge Demon's transbrake will. The quarter-mile time and trap speed of 11.3s (even with rollout) and 130.6mph are the weather-corrected results. 0.4sec and 3.4mph slower than what were published in M/T's database. This means without rollout, the actual tested 1/4-mile time was as high as 11.6 seconds!!!
Hope this helps ;)
