2015 Nissan Z may be lighter, leaner

370Z Purist

Big things to talk about if the Z line ends up staying similar to what it is now, a high compression, relatively high displacement V6 which is naturally aspirated. If Nissan stays in this vein, they'd first have to rebadge. The Z has only gotten larger as the years have passed, and unless they mean to go the way of GTM and slap 420Z on the back, it will likely end up as the "Z" car.

No one mentions Mazda's SkyActiv, which is a good way to increase power using an existing displacement number. Stay at 3.7 liter, jack compression up to 14:1, use premium fuel. Dynamic compression numbers often put boosted engines at that level of compression, so it's not impossible. Go slightly smaller, maybe a 3 liter, but still naturally aspirated, with that kind of compression, then shrink the car down to 240Z size. You're still seeing horsepower numbers at 275+, along with a lighter curb weight and more efficient use of fuel. My conjecture is also as baseless as that Edmunds article, which they KNOW would cause a lot of rumors to fly. I mean, who just says "oh maybe a 4-cylinder" unless they WANT it to spread.
