2009 Infiniti G37

There are some changes on the powertrain side as well. The 3.7L V-6 in the convertible has a slightly lower output of 325 hp and 267 lb-ft versus the G Coupe's 330 hp and 270 lb-ft. Like the coupe and sedan, the convertible will receive Infiniti's new seven-speed automatic transmission with available paddle shifters or a close ratio six-speed manual.

The G37 Convertible will be offered in just two trims, base and Sport 6MT. The base version comes with the seven-speed automatic transmission and 18-in. wheels with all-season tires standard as well as countless features including dual side impact and side curtain airbags, keyless ignition with push-button start, active head restraints, and cruise control. The Sport 6MT obviously comes with the six-speed manual transmission plus 19-in. wheels with summer tires, sport-tuned steering, upgraded four-piston front and two-piston rear brakes, sport seats with adjustable bolsters for the driver, and aluminum pedals. All performance upgrades found on the Sport 6MT are available for the base model as part of a sport package, but neither sport version can be had with climate-controlled seats. Also available are Bluetooth, a navigation system with a 9.3 gigabyte hard drive instead of a six-disc CD changer, and intelligent cruise control.

Fuel economy has not been finalized, but mileage should be slightly lower than the coupe due to the extra heft. The automatic-equipped 2009 G37 coupe is rated at 18/26 mpg city/highway and the manual at 17/25 mpg. Pricing has not been announced, either, but the convertible should carry a decent premium over the coupe. For comparison, a BMW 3 Series convertible costs about $8000 more than a comparable coupe.
