More power and revised styling mark 2005 for Infiniti's least-expensive models. G35 comes as a rear-wheel-drive sedan and coupe or as the all-wheel-drive G35x sedan. The only engine is a 3.5-liter V6. Rear-drive G35s are available with a 6-speed manual transmission or 5-speed automatic with manual shift gate. The G35x is automatic only and has a Snow Mode that allows the driver to lock in a 50/50 front/rear torque split. With automatic transmission, sedans gain 20 hp for 2005 to share the coupe's 280-hp rating. Manual-transmission sedans and coupes now have 298 hp, a gain of 38 for sedans, 18 for coupes. Standard on all are antilock 4-wheel disc brakes, front side airbags, and head-protecting curtain side airbags; the coupe's curtain bags cover only the front seats. Leather upholstery, heated front seats, and xenon headlights also are standard. Wood interior trim is optional on automatic-transmission G35s. A navigation system and satellite radio are optional on all. Limited-slip differential and sport suspension are standard on manual-transmission models, optional on rear-drive automatics. Rear-drive sedans get 18-inch wheels with manual transmission, 17s or optional 18s with automatic. The G35x is available only with 17s. Coupes get 19-inch wheels with manual transmission, 17s or optional 18s or 19s with automatic.
