Infiniti G35

Introduced in 2003, the Infiniti G35 replaced the G20 while adding more interior room and power.  The  sedan trims started out with a 3.5 L, 260 hp V6 that grew to 280 hp in 2005 and finally broke 300 hp after its 2007 re-design.  The coupe trims had about 15-20 hp on the sedans until 2007, when the sedans caught up to and surpassed the coupe's powertrain.  

As for the 2007 re-design, Infiniti re-did pretty much everything on the G35.  You'll find a new interior, exterior, and a more powerful engine.  Bluetooth technology helps keep the G35 up-to-date.  

Early reviews indicate that this sleek sedan has made progress and that the 2007 changes indicate another step in the right direction.  The G35 still has some room for improvement in terms of interior room, trunk space, and handling.
