2011 INFINITI G: What's New, Specs & Features

Last updated August 4, 2026

The biggest change for 2011 is the arrival of the G25 sedan family with a smaller 2.5-liter V6. This is a lineup-expansion year rather than a redesign, with the first IPL G Coupe, new special editions, and modest coupe and convertible updates.

About the 2011 INFINITI G

V36 generation. For 2011, the sedan is in its fifth model year, the coupe is in its fourth, and the convertible is in its third. This is a lineup-expansion year after the 2010 refresh work, not a new generation.

INFINITI positions the G as a luxury sport-car family built around strong V6 power, rear-drive balance, and a richer standard-equipment list than many rivals. The core idea is performance first, but without giving up leather seating, upscale cabin materials, and daily-driver comfort. In sedan form it targets shoppers who want a sharper, more driver-focused alternative to mainstream luxury sedans; in coupe and convertible form it leans even harder into style, sound, and response, with AWD and special editions broadening the appeal.

The 2011 range stretches from the simpler G25 luxury sedan to the 348-horsepower IPL G Coupe, the top factory performance version. Journey and all-wheel-drive models emphasize everyday comfort and traction, while Limited Edition models add navigation, Bose audio, sport brakes, and distinctive exterior and interior trim.

What changed, by category

Powertrain

The new G25, G25 Journey, and all-wheel-drive G25x sedans joined the range with a 2.5-liter V6 and seven-speed automatic transmission. The first IPL G Coupe added a tuned 348-horsepower 3.7-liter V6 with a six-speed manual or seven-speed automatic.

Styling

The G coupe and convertible received a revised front end with the fog lights mounted lower, along with new wheel designs. New Sport Appearance and Limited Edition variants added distinctive body and cabin trim, while the prior G37 Anniversary Edition left the lineup.

Tech

The manual-transmission G37 Sport coupe and convertible gained standard navigation. The touch-screen monitor also moved from optional to standard on the G37 Sport.
