2014 G37 Sedan Overview:  2014 G37 Replacement Is Released

updates:  Infiniti G37 Rumors - MotorTrend Insider Review

The G-Series is running on a production plan with new designs being released every 4-5 years. As the current design was released in 2007, the new redesigned sedan should be released in 2012, followed by the new coupe in 2013. Some have stated that the 2013 coupe may have similar lines and looks as the Essense concept, which Infiniti has already indicated is a precursor for the brand's future design direction. I would surely not dismiss this notion as the new Infiniti M-series has already been equipped with a similar grille as the Essense concept and we all know the current version of the coupe is pretty much spot-on in it's resemblence to the 2007 Infiniti Concept. So, from an exterior design aspect we do have an idea at least.

New G-Series Hybrid
As with most new models, rumor and speculation always seem to start kicking in the closer a new release date is approached and reports, along with artists renderings, have been showing up on the internet and via published magazines. One such report started late in 2009 with the speculation that a hybrid G would be released sometime in 2013. While some dismiss these early reports, the release of a M35 hybrid should have proven that Infiniti is on a quest to go green, or at least have that option. Some of us expected future hybrids as Infiniti has had at least two G-series hybrids built for testing in recent years. We can only hope that Infiniti is able to keep the price right on these models as that has been a big issue with other hybrids on the market.

2012 infiniti G37 concept design with a 2.5 turbo At this point, it's pure speculation on what will really be offered from a motor perspective. Edmunds reported rumors of a 2.5 liter turbo sedan, utilizing the VQ25 v6 from the Nissan Skyline 250GT, making a showing on the Fall 2010 auto show circuit. Later, Edmunds reported a 2.5 liter Mercedes-Benz inline 4 as a possible direction. Autoweek has also
reported that future versions of the G-series may get a Mercedes-Benz engine as part the global alliance between Daimler AG and Renault-Nissan while Road&Track reported further about a hybrid to receive a 3.5L V6 + Electric motor combination, 7sp automatic transmittion, 400bhp, and included the a bove conceptual drawing. While I would not dismiss a potential 3.5L hybrid I would disagree that Infiniti would offer it with that much power. Additionally, there have also been rumors of a possible diesel motor being offered, although I have been told that any consideration of this option has been dropped. Then, you have the current 3.7L VQ-series motor which is a known performer and a long-term winner of Ward's 10 Berst Engines, what about it or why would Infiniti consider replacing such a strong series motor with another?

Eventually, only time will tell as those that know are keeping silent or only leaking bits at a time. I would expect much more information will be headed our way in the next 6+ months as to the design and motor changes available and whether there is a G25t or G35 Hybrid to be released along with the G37. Until that time, we can only consider the options and browse renderings that are showing up on the Internet as seen below:

2012 2013 Infiniti G37 Concept drawing Update: July, 2011
Road&Track posted an article with yet another illustration of a potential G-coupe replacement which includes M-series sport wheels, and is heavily influenced by the Essence concept. Suggestions of engine options are all over the board from a
potential Mercedes-Benz 3.5 litre V6 to the M-Series 5.6 liter V8 and even a side trip towards the 5.5-liter or 6.2-liter AMG V-8's. Quite the wild guesses. Still, it's interesting to see the possibilities and wild guesses.
