Actually C&D had a couple of comparos or articles in which the G35 came ahead of the BMW.
If we're talking E46 3-Series versus first-generation G35, true. But the E90 328i has beat the second-generation G35 on two separate occasions now in C&D tests--both in a one-on-one comparison and, in the new one, with the CTS coming in third and the C300 Sport coming in last.
Still, the first-gen G35 is just one example. There's a couple out there. But as a C&D subscriber, I can tell you that BMW almost always wins C&D tests. They like Bimmers A LOT, and their results show that.
