Nissan eventually plans to phase out the V6 for a turbocharged four-banger

Looming EPA regulations have resulted in big changes in the automotive world. We've seen a number of V8 engines give way to turbocharged V6s, while V6 engines in midsize sedans are being tossed or replaced with turbocharged inline-4s.
 
We're also on the cusp of seeing huge weight reductions for iconic automotive nameplates. The Ford is reportedly eyeing a 700-pound weight reduction for the next generation F-150 and a 400-pound weight reduction for the next Mustang.
 
According to a new report from Motor Trend, another fan favorite is going on a diet all in the name of performance and fuel economy concerns. The next generation Nissan Z (codenamed Z35) will lose two inches in width and a whopping 400+ pounds. The huge weight reduction would put the next generation Z below 2,900 pounds.

Motor Trend's sources indicate that while Nissan plans to offer the next generation Z with a V6 when it launches, the "master plan" is to phase out the V6 entirely in favor of a turbocharged, 2.5-liter inline-4. The turbo four will reportedly pump out 330hp, putting it on par with the 3.7-liter V6 used in the current 370Z.
 
The weight reduction and move to four-cylinder power should allow the new Z to achieve EPA numbers far better than the current car’s 18/26 mpg (city/highway) with a manual transmission.

Speaking of complexity... I'm sure all that variable lifting timing stuff adds a few moving parts here and there.

...and while I don't think your assertion about fuel economy is necessarily wrong, one thing about most factory turbo motors is that they deliver full torque at lower rpm's than a similar powered NA motor. Unless your talking about much bigger displacement, a 4 stroke NA motor has to spin up to get a few more bangs in to deliver the power.
