At the Z car’s U.S. introduction 40 years ago, Datsun wisely chose not to employ its domestic “Fairlady” moniker, which Yutaka Katayama knew would have been tantamount to calling, say, the Corvette the “Cocker Spaniel.” Since then, the hyphen that originally separated the “240” from the “Z” has vanished, 1.3 extra liters of displacement have more than doubled the original engine’s output, an actor briefly made Mr. K a red-bespectacled TV star, and the car’s price has swollen by about $27,000. Nissan refers to this latest Z as an “enhancement,” likely largely a male enhancement, rather than a whole new car. The company is being modest. The wheelbase is shorter by 3.9 inches, width is up 1.1 inches, length is down 2.7 inches. The larger engine (same V-6 as in the Infiniti G37) produces 332 horsepower, a bonus of 26, and sits 15 millimeters (0.6 inch) closer to the pavement, which is now hugged by a true unequal-length control-arm front suspension. Although Nissan’s engineers had to add nearly 200 pounds of safety and regulatory bric-a-brac, the car is only 33 pounds heavier than the 350Z we tested in June of ’07, in part because the hatch, A-pillars, and doors are now aluminum. We know, because we attacked them with a “Big Sky” fridge magnet.
