The JX35 does feel more powerful than the 265hp it is rated at. I would agree the "from a stop" acceleration is not breathtaking, but the passing power and speed is quite impressive. I have not fiddled with the Sport mode much, but this does seem to make a significant difference. I also own a G37, so I do know what fast is, but I am really impressed with the JX35 powertrain. If you want a V8 or something like an Escalade, get a QX56 and blow the Caddy out of the water. JX would be compared to the Caddy SRX, and with that there is no comparison. I briefly considered an Saab SUV (same as SRX) in the Aero package, but between the smaller size, no warranty, terrible fuel economy, and some feature content, I ruled that out even at the $33K price tag (which is a total deal!)
