This is 100% correct, now if Audi had its SQ5 out, I might have considered it over the X3 35i, BUT it would not be faster, it will most likely have the 330 HP S engine and equal 0-60 time as the X3 35i (just like the 335i and S4). If BMW releases any sort of MX3 (sounds like a Mazda) it will easily outperform the SQ5. Only thing the SQ5 will have going for it is being a little more sporty than the X3 (even with M Sport package) because Audi is changing the exhaust setup and interior (seats, steering wheel) a little for the SQ5, BMW only changed the bumpers and steering wheel.
