With its 3.6-liter direct-injected V-6, the 2009 Cadillac STS is a solid performer with decent comfort, and it’s one of the closest rivals to the Infiniti M in offering a compromise between sport and luxury.
The new 2009 Acura RL takes off in a new direction stylistically—which might appeal to some and repel others—and the primarily front-wheel-drive RL is at its best in all-wheel-drive (SH-AWD) form.
The traditional German brands naturally slot in thanks to their reputations.
However, the 2009 Infiniti M (either the M35 or M45) tends to be a nicer combination of comfortable appointments and a charismatic driving personality, leaving the Mercedes and Audi feeling perhaps overly conservative and technical.
