The Z two-seater shares mechanical components with the Infiniti G coupe, including a wonderfully strong and smooth V6. Acceleration is very quick, and fuel economy is respectable. The six-speed manual is a bit notchy but easy to use. It can match revs on downshifts, a neat touch. Handling is very agile, with quick steering and lots of grip, but somehow the car isn't as engaging to drive as one would expect. The ride is very stiff and choppy, and road and tire noise are constant. The Z's well-finished interior is cramped, and visibility is lousy. A convertible is also available. Reliability has improved to above average.
