I drove two of those things about 265 miles each, but they were both automatics. I can't answer your question, but they're powerful enough at speed. I quickly and easily reached 95 MPH when I semi-punched it from 60. I immediatly backed off down to 70-75, as I was just testing, not racing.
The only bad thing I noticed about this engine is that it is not quite as smooth as a new Honda Accord's or Toyota Camry's 4 cylinder, but it's by the narrowest of margins and with all the HP this thing has, I wouldn't even care. I've owned much worse cars.
Since the "cheap" interior always gets brought up, I'll add my comments; I liked the gray cloth interior more than the black leather interior. Though they both have the same parts, the black plastic looked cheaper than the gray, and with leather, the cloth insets on the door panels are replaced with vinyl. If you want a nice leather interior in a Nissan, you should be looking at a Maxima, IMHO.
