VQ37VHR, the first Infiniti engine to feature VVEL. It too came with either a 5-speed automatic or 6-speed manual. All manual G models include a sport package. The 2009 G37 convertible was launched in June 2009. The 2009 model G sedan followed suit using the same VQ37VHR engine. Also for 2009 the 5-speed automatic was replaced with an all-new 7-speed and both the sedan and coupe gained a self-healing paint finish from the Infiniti EX. The V36 platform continued for 2010 with numerous interior changes and upgrades as well as a mid-product cycle exterior update for the sedan. In late 2010 the Infiniti G25 went on sale as a 2011 model, featuring a smaller 2.5L version of the VQVHR engine to allow the G to better compete with the Lexus IS250 and BMW 328i. Pre facelift models 2007–2008 G35 Sedan The G35 sedan underwent a major revision for the 2007 model year. This 2nd generation front-mid (FM) platform underpinning the new G is shared in part with the Infiniti M and has several structural reinforcements around the engine and rear floor area, along with three times more laser welding and 16 percent more spot welds than the old version; overall body stiffness was improved by 40 percent. Single-pivot lower control arms in front replace the 1st gen model's twin lower links. The G35x sedan uses an ATTESA E-TS all-wheel drive system. Along with these chassis refinements, Sport package equipped models came with firmer rear shocks, bigger front brake calipers, and larger rotors all around (up from 12.6/12.1-inch front/rear). Sport package equipped cars also get a viscous limited slip differential. An all-new Active Steering package can be ordered for sport package equipped models. It features a planetary gearset on the steering shaft (similar to BMW), that varies the steering ratio between 12.0:1 and 18.5:1. A rear-wheel steering system that induces up to one degree of rear steer is also included in this package. The Active Steering package includes even stiffer shocks than the sport package at all four corners and the ride has been repeatedly reported as being too stiff for most customers except the most "enthusiastic" drivers. Base and Journey model 17 inch wheels were fitted with wider 225 section tires (up from 215), while the 18 inch wheel upgrade (included in sport or wheel package) with 225/50-ZR18 front and 245/45-ZR18 rear is now a size smaller in front and
