Over here on FL's sister site AT, the 458 Speciale is reported to do the 400m sprint in 11.0sec. That's accurate, even with the 9.2s 0-200kph time.
I don't mean to badmouth Ferrari, but sometimes their 400m estimates are based on a prepped strip, perhaps without the one-foot rollout; or it could be the other way around. American automakers absolutely do both.

10.7sec is possible with EITHER a rollout OR on a dragstrip. A 10.4sec time is possible because the 458S, the 12C, and the original Aventador/Huracan all share the same power-to-weight ratio.
Ferrari and US automakers are rarely "conservative" with any performance figure.
