2011 Infiniti M56: Donate a Kidney To The Z

April 06, 2011

The 5.6-liter V8 that goes into the Infiniti M56 is a beast. It's one of the two things I like most about our car. But it's a shame that the V8 sees such limited play in other models. So how about this, Nissan: Figure out a way to shoehorn it into the Nissan Z to create a limited run of 560Zs. Would this not just be super cool?

First of all, it would fix the biggest issue I have with the current Z: it's a great car in need of a great engine. The current 3.7-liter V6 is just too buzzy and just kills the character of the car. The V8 isn't a high revver, but I think I could live with that given an increase to 420 hp and 417 lb-ft of torque. Plus, I'd argue the Z needs a power increase if Nissan hopes to compete with the latest models of the Mustang and Camaro. Last month, the Camaro outsold the Z nine to one. The Mustang, eight to one.

No doubt it'd be a tough thing to do. Maybe the V8 wouldn't fit in the Z's engine bay. Maybe Nissan doesn't have a manual transmission suitable for the V8's power. Maybe it'd bring an unwelcome change in weight distribution or handling. Maybe it'd be really expensive. Maybe the reduction in fuel economy would further mess up Nissan's CAFE goals. Probably, it's all of the above.

But it's nice to dream, right?
