Pfft - a Boeing 74F (Boeing 747-400 Freighter) vs. a 911 Carerra sport from a standing start?
Even unladen, the 74F will reach vR (rotation speed) at about 132 knots (depending on weight, atmospheric conditions, and lots of other factors) which is 244 kmh (151 mph). On a standard atmosphere day with a dry runway and zero freight, zero wind and no limitations, it'll take about 7000ft of runway (2133 M) to get a bare B74F airborne.
Porsche claim the standard top speed for the 911 Carerra (2008) is 328 kmh (204mph), with 0-60mph in 3.6 seconds.
Therefore, some simple math, will show that this is indeed, a load of fluff. (Hint, have a look at the mph).
Still, they are both magnificent machines.
Personally, I prefer Jet-A rather than Premium
