Rain man was right on. He was very good at math. So basically, by saying it is rain man math, you agree.

But based in your second sentence, I think you meant to say that it was Duh-bya math.

At any rate, K-A is probably right, but perhaps a bit high if you consider the 5er has an 8 speed gearbox. What matters is the total area under the HP curve from start to finish (I'm trying not to use math here). With the 8 speed gearbox, you stay at the top of the curve a bit more so you end up with more total under-the-curve area by the end of the run compared to say, the GT. So there is *some* benefit to the 8 speed gearbox (maybe it's 10-15 HP benefit or something; to know would require using math and I'm many years removed from that ).

But even if you assume a super efficient 15% drive train loss, then 277 RWHP puts it over the 300 @crank HP claimed by BMW (about 326 HP, to be more specific, which would probably be enough to get the vehicle to 100 trap with the 8 speed gearbox).
