2011 Infiniti G25

Insideline website has reported that Infiniti will launch a smaller-engine version of its G sedan this fall and the entry-level model will be called the G25.

According to Insideline the new G25 use the 2.5-liter V6 Nissan uses in the Japan-market Skyline 250GT (The Infiniti G is sold in Japan as the Nissan Skyline.)

The new Infiniti G25 is aspirated DOHC engine, which is rated at 210 horsepower and 195 pound-feet of torque in Japan. That's enough to be competitive with the 3.0-liter inline-6 in the BMW 328i, which is rated at 230 hp and 200 lb-ft and it's a little stronger than the strong-selling Lexus IS 250, which is rated at 204 hp and 185 lb-ft.

At launch, the smaller V6 will be in the G sedan only and it will be sold alongside the also naturally aspirated V6-powered G37. The idea is that the lower entry price and improved fuel economy of the 2.5-liter engine will give Infiniti more head-on competition for the popular BMW 328i.

As of now, a G25 coupe and convertible are not planned, but if sales are brisk on the G25 sedan, both will happen.
