We usually assess convertibles in terms of structural rigidity, the square root of all vehicle dynamics. Rubbery bones don’t enhance transient response, and there’s the disconcerting phenomenon of dashboard and steering column jiggling to the beat of slightly different sambas.
But that’s not the biggest concern of a team convertibilizing a fastback coupe. They’re wondering whether their baby will be seductive. Makes sense, right? After all, a guy surveying the traffic at a hookup bar isn’t thinking about structural rigidity (other than his own).
When it came along in 2003, the droptop Z car scored well on the rigidity meter. In our August ’03 comparo [“The Blow Dryers”], we noted a “feeling of enduring solidity” and that “nothing flexes.”
But the looks left us lukewarm, particularly with the top up. One pundit was reminded of the USS Monitor, the 1862 warship with a single turret perched on a long, flat deck.
Behold the 370Z convertible. Like the 350Z, it derives from a fastback coupe. But this convertible—which originated at Nissan Design America in San Diego—was more thoroughly baked into the new Z’s development program. The result is a design that’s much more integrated, much less a slab-sided afterthought.
In addition to its good looks, the new convertible is also easier to live with. The seating position is a little higher than before, providing a better view of what’s going on ahead. (Being in the command center in the previous Z-vertible was like sitting in a foxhole.) With the top up, the view straight astern is also improved, though here the distinction is academic, and as with so many convertibles, the rear-quarter sightlines are blind.
