370Z Test Drive - Questions

bigsix · 10-27-2011, 08:48 PM

I test drove two 370z's:

- The first was a Nismo. I noticed the engine was erratic in its power and torque delivery...like something was wrong. Maybe the ECU needed to be re-set (?) I'm not sure... red-lining 1st gear from 5 mph was kind of crazy: like a true combustion/explosion happened under the hood and what felt like a drop in power but much more noise after 5,000 rpm.

- Then a Roadster. This engine was very smooth and linear. It didn't seem to have the soft low end the Nismo had, nor did it have erratic jumps in power while revving into higher engine speeds.

Both of these cars were new, so I'm not sure what was going on with the Nismo ?

It was probably spinning and VDC was limiting it. The first time I hit the traction control in a car that was aggressive with it, I thought I had blown the engine.

Hadn't thought of that.
