N52 "quicker" than previous X3 engine?
In the press release on the BMWNA web site it states that the new X3 28i N52 engine will be nearly a half-second quicker (0-60 in 6.7 secs.) than the previous X3 30i engine. The N52 gives 240 HP instead of 260 HP in the previous platform. How is this increased quickness possible, especially with the increased 2011 X3 dimensions, i.e. length, width, etc?
