Motor Trend is reporting today the Cadillac SRX could be replaced by a five-passenger Art & Science-design BMW X3-sized crossover for the 2011 model year. That makes sense if it's going to share architecture with the 2009 Saab 9-4 — the replacement for the much larger 9-7x. For the engine, the US version will come from GM's new direct-injection gas 3.6-liter V6 with a two-mode hybrid system optional and a diesel V6 using "closed loop combustion" overseas. Sounds like a fun little luxe-UV — however, MT's also reporting it'll be designed primarily for the Euro and global market with US sales coming afterwards. Man, they always get the cool stuff across the pond first, don't they? [Motor Trend]
