Infiniti G25 2.5-liter V6 power plan

Until now, the company had only the G37 to do battle with entry-level versions of BMW's 3 Series and the Lexus IS, which in terms of cost and performance was sort of like deciding between a cigarette lighter and a flamethrower. The G25 now shoulders that duty, positioned squarely in the same output and price category as its entry-level lux-marque competition.
Known as VQ25VHR in Nissan-speak, the G25's 2.5-liter V6 power plant is built on the same architecture as the 3.7-liter V6 found in the G37. The G25's engine is consequently only smaller in terms of swept capacity — externally, the two engines are clones.
This commonality presents something of a problem since the "smaller" engine doesn't result in significant weight or manufacturing cost savings. Fuel economy, too, at 20/29 city/highway mpg, betters the G37's 19/27 mpg showing by just a hair while giving up a not-inconsiderable slice of power and torque.
So in order to keep the 2011 Infiniti G25's sticker from potentially ballooning past that of a bare-bones G37, Infiniti withheld from the G25 a few whiz-bang option packages. The G37's Premium, Sport and Technology offerings are deleted for the G25, as is a navigation system. But then, this is the entry-level version, remember?
