For 2013, Infiniti has dropped the G25 models, as well as the G37 Sport Appearance Edition and G37 Limited Edition from the lineup, leaving just three models: G37 sedan Journey, G37 Sedan Sport 6MT, and G37x Sedan AWD.
Across either model, standard equipment includes leather upholstery, power front seats, automatic climate control, a six-speaker audio system, and XM satellite radio. Journey models add Bluetooth, a rearview monitor, heated seats and mirrors, and dual-zone climate control.
If you're a driving enthusiast, you might head straight to the G37 Sedan Sport models; they're focused toward those who like mountain roads and plan track time—so they include a Viscous Limited Slip Differential, in addition to a host of track-worthy upgrades like larger vented disc brakes, sport steering gear, W-rated performance tires, plus active head restraints and thigh extensions (which taller drivers will love) in the more aggressively bolstered sport seats.
An audiophile Infiniti Studio on Wheels system by Bose is optional, as is an optional next-generation hard-drive-based navigation system with higher-resolution screen, XM Weather, XM NavTraffic, and live rerouting, as well as Zagat restaurant ratings and reviews.
