Although BMW still rules this class-entry-level luxury sports sedans and coupes -- Infiniti keeps edging closer to parity with the Germans. A 2003, '04, and '07 10Best winner, the G returns for '09, thanks in large measure to the sedan's new 3.7-liter V-6 rated at 328 horsepower, an increase of 22 over the previous 3.5-liter six.

We're not immune to the appeal of more power, of course, but there's more to the G's story than increased muscle. The powertrain team also improved the refinement of the V-6 and the engagements and feel of the six-speed manual transmission, putting it on par with, if not ahead of, the gearbox in BMW's 3-series.
