Yet all this extreme sport sedan stuff doesn't get in the way of civility where the 2009 Acura TL SH-AWD and 2009 Infiniti G37 Journey are concerned.
Both cars exhibit a certain suppleness when the roads prickle their backs, with the edge going to the more supple TL. The backseat in both cars provides the kind of legroom that makes long road trips a realistic proposition.
We have two very accomplished sport sedans in the TL and the G37, and their differences in character are more a matter of personal preference than in capability. The scoring was close enough between the two that the G37's $2,730 sticker price advantage took on increased significance.
Ultimately, though, the 2009 Acura TL SH-AWD couldn't claw its way back from the drubbing given to it by the sheer speed of the 2009 Infiniti G37. It doesn't hurt that the G37 really shrinks around its driver when you want it to and expands when you don't. In this respect, the G37 is the four-door sports car you always wanted, the car that lets you change and grow up without forgetting where you came from.
