End of the 300ZX era
... or ... "they were the best damn sports cars in the world"
|
Prelude
The 240Z was the first Japanese sports car to move the needle in America, with its 2.4-liter
in-line six, disc/drum brakes, and giveaway price tag. Throughout the 1970s, the Z-Car-including
the larger, more powerful 260Z and 280Z versions-carried the company around on its back.
Almost ten years later, Nissan introduced the 280ZX version on the 810 sedan chassis, with
trailing-arm rear suspension, a five-speed manual gearbox, and an anemic 135-horsepower smogger
engine. In spite of the weak engine, the 280ZX outsold all previous versions by a country mile.
The 280ZX Turbo came along in 1981, with a 180-horsepower boosted in-line six, and that was the
last car of its generation.
The second half of the 1980s brought the 300ZX. With a 3.0-liter V-6 engine, a much slicker
body shell, and more luxury, it was more GT than sports car. The standard 160-horsepower V-6
was augmented by a turbocharged version rated at 200 horsepower and a chassis equipped with
driver-adjustable dampers. The 1984 300ZX broke all existing sales records and became the
best-selling sports car on the American market. Nissan tweaked the 300ZX once for 1986 and
again in its last year, 1989.
Climax
For the 1990s, Nissan brought together all of the lessons it had learned - from the American market,
from its very successful Z-Car and IMSA GTP racing, from its previous V-6 engine designs, and
from its earlier turbocharging prowess - to produce a completely new 300ZX.
For starters, the envelope was much slicker and more contemporary than any previous Z-Car.
As with some of the 280 and earlier 300 versions, the new model was sold in both coupe and
long-wheelbase 2+2 versions, with optional T-tops and five-speed manual or four-speed automatic
gearboxes - lots of choices for buyers.
The engine for the new-generation 300ZX was entirely new, with dual overhead camshafts
(the previous version had a single overhead cam) and four valves per cylinder with variable
intake-valve timing, and a 10.5:1 compression ratio, generating 222 horsepower. Here was a
7000-rpm engine that would pull the 3500-pound ZX from rest to 60 mph in about six seconds flat.
But there was more a lot more. The bespoilered Twin Turbo version carried three slots in the
nose and two intercoolers to cool a small, quick-spooling Garrett turbocharger on each bank
of the V-6, pushing 9.5 pounds of boost and generating 300 horsepower at 6400 rpm (the magic
100 horsepower per liter) and 283 pound-feet of torque.
The Twin Turbo also carried twenty-percent-stiffer springing, two-mode electronically
adjustable dampers, Nissan's Super HICAS (High Capacity Actively Controlled Suspension)
four-wheel-steering system that moved the rear tires through a range of two degrees to help
the car corner, and staggered rubber, 225/50ZR-16s front and 245/45 ZR-16s rear. A set of
11-inch vented ABS disc brakes ensured consistently decent stops.
Nissan offered the Twin Turbo only as a two-seat coupe, and only with T-tops, but it also
faced consumer reality, offering a detuned, 280-horsepower version with the 4-speed automatic
transmission. In every model, though, the interior was essentially the same. One of the coolest
cockpits of the era, it mimicked some of the car's exterior curvatures, with a beautiful array
of instruments and controls and a console arranged in a tight, driver-centric layout.
Every car magazine in the business showered the new ZX with praise and awards, ("Dollar for
dollar, it's the best damn sports car in the world," exclaimed one).
The reasons this car was so successful are manifold. It looked slick and smooth against the
contemporary coupe competition (Toyota Supra, Mazda RX-7, Porsche 944/968, Chevrolet Corvette).
It made huge power for the time. The instrumentation was racy and complete. The bucket seats
were heavily bolstered, comfortable, and containing in the corners. The shifter was among the
best on the market at the time. The combined V-6 engine growl and four-pipe exhaust note were
otherworldly attractive.
But most people bought the ZX, and especially the Twin Turbo, because it went like hell from
stoplight to stoplight (about fourteen seconds flat in the quarter-mile, at over 100 mph), and
went around corners better than a 3500-pound Japanese sports car was supposed to
(about 0.9G on the skidpad), aided by the fat, staggered tires and Super HICAS rearsteer gear.
If the 300ZX Turbo had one glaring fault, it was its tendency to break the rear tires loose
in fast corners when the boost came on.
That one foible, however, was more than offset by the last 300ZX's slick styling, everyday
driving useability, tractability, good road manners, and a willingness to turn in at the flick
of the wrist and stop progressively and neatly from extralegal speeds all day long. In its day,
the 300ZX was one of the very best driver's cars available, and cheap, too.
Windup
For about $33,000 to start, the 300ZX Turbo was in a class by itself. Unfortunately, the
price didn't stay stable over time, rising more than $4000 due to ongoing yen/dollar complexities.
That, and impending federal regulations that would have made the car much heavier, put an end
to the 300ZX era in 1996.
