Just so people don't panic here, Infiniti's new M car will feature a V8 that produces above 400+ horsepower.

The M was already offering a V8. Its just not going to be added to the Z

yea looks like someone put a G and Z together lol

and a new model usually last for about 4-5 years

Well i hopes the new "Z" will not be a 4000cc monster,road tax too high...

You can expect the next-gen Z a few years from now, with a direct-injection NA V6.

Yeap the 350Z was from 03 to 08, 5 yrs. So expect the same for the 370Z unless something dramatic happens.

Nissan Titan engine, nothing new.

I would see the GT-R going 4.0 TT and the Z getting a 3.8 or 3.9 with DI and all those goodies. I am sure Nissan could easily push out a 400hp (flywheel) 3.9 V6 engine after the 370z.
What will Nissan really do? Who knows, they might jump ship and do what BMW did and jump to a V8, but I almost feel like if they do they will also do what BMW did. They bloated out the M3, and while it still is quick, faster, etc. it is not the same car it once was.

my prediction, with the new looming fuel economy standards is that the next Z will be a 240Z. 2.4 direct injection turbo, 300 hp. Thats just a guess, but I can see it happening.

:iagree:

I see either this, or a smaller V6 combined with electric motors, to get the fuel economy there and retain performance.

hopefully it comes with beefier internals.

I don't think they will change the 3.7 Engine for a good time period. Probably they will increase power, efficiency, internals of that particular engine, but I don't see a bigger engine on a Z.

Yes they do....they are already 5 years out on the engine design curve.

I know they will have to push out some more HP either NA or FI. And Im sure they will do DI and maybe they would be nice and do a magnetic ride too. And of course use that new technology in noise dampering.

nissan would be foolish to try and pump out another Z with a new engine. it actually hurts buyer loyalty if a company keeps changing the specs ever couple years. also with the big push to get away from using gas. tghis is pretty much the big last stand for high performance gasoline engines. nissan.lexus,ford,gm,dodge, merc,bmw ect all are using the majority of there resources in future electric/fuel cell cars. if nissan was smart they wouldnt worry to much about trying to pump out a bigger badder Z and just take a backseat for a couple years let the big boys duke out and them spend there time coming out as the top dog in the future cars.
