Carrera 4S PDK vs X6 50i vs Cayenne GTS
Strange comparison I know but like the title says BMW reckons the X6 handles like a Porsche...
No M3 in this comparison, but given the 911 Carrera is seen as somewhat of a competitor for the M3 I thought I'd post it... |

Those comments of the X6 mirror my own about the brother's X6 in comparison to the Cayenne I owned. The only thing I can say that complimentary is that they are surprising lively but as for the rest, it's stability under braking, it's steering feel and the feel it gives through a corner doesn't compete with the Cayenne.

I'm really impressed by the performance of the Carrera in the hot conditions although that area of Australia is generally pretty dry (i.e. low humidity). I know the M3 definitely feels hampered when the temperature gets into the high 20Cs (I do live in a high humidity area, this also will impact).
I wonder if direct injection helps with higher intake air temperatures? |

A big concern with the X6 5.0i was the comments that after a lap and a half the engine went into 'limp' mode due to overheat!!!
Is this a problem just because of the excessive heat which is extreme to most of Europe but not so in the USA or is it a underlining design fault with the new 4.4v8 Bi-turbo, maybe positioning the turbos in between the vee was good from a packaging and lap perspective but bad for excessive hard driving. More tests may be needed to determine this one. |

This of course was the problem with the early 335i's too and the N54 engine. They came out with it and had no second oil cooler for a twin turbo engine. Too this day hot weather and hot lapping gets the N54 engine hot and can make it go into a limp mode. BMW simply needs to install larger oil and FMIC's on their TT engines. Further, they need to increase the size of the air intakes to make sure it gets plenty of fresh air in there. Lastly small heat release vents on the top of the hood above the turbos would be a good thing too. Of course they'd need to be design so water does not run down them, but rather out into the wheel wells or something. I haven't read that the next M5 will have the TT 4.4 My guess, in order for it to be an M engine, they'll either design a different engine with the TT on it or it will be a heavily modified version. The 4.4 TT as it stands is top heavy, not sure BMW would want that in the M5, but again, who knows, with modifications, they could lower the center of gravity of that engine. I like different comparos like this magazine did. It gets old always seeing the same cars tested against each other. |

It is apparent that BMW didn't learn their lesson with the 335i or N54. They need to invest in better oil coolers. The temps get too high after a little hard driving and they go into limp mode. |

I don't want to comment on this because some people read too much into things but I will say that certain other companies DO have much more experience of FI, though BMW are gaining ground fast. |
