The Nissan 300ZX (called the Fairlady Z in Japan) is a sports car that was produced by Nissan. It comprises the third and fourth generations of the Z-car line-up, respectively given the chassis designations Z31 and Z32.[1]
The 300ZX name followed the numerical convention initiated with the 240Z, put forth by Yutaka Katayama, the one time president of Nissan Motors USA. The "X" was added to themodel name by its predecessor signifying "luxury". The name was used in most markets with the exception of a few including the Japanese home market, there the car like all previous Z cars was sold as a "Fairlady Z". The best selling 300ZX's were the Z31s, with over 100,000 more sales than the Z32.
The Z31 and Z32 feature a 3.0 litre, V6 naturally-aspirated and single (Z31) or twin (Z32)turbocharged engine. Although both motors are from the same VG series and have the same displacement, the power output of the Z32's VG30DE and VG30DETT engine is greater than the Z31. The VG30DE engine also has a double overhead cam and variable valve timing while the older VG30E is a single overhead cam design. The naturally-aspirated Z32 has 222 hp (166 kW) and 198 lb·ft (268 N·m) of torque versus theZ31 with 160-165 hp and 174 lb·ft (236 N·m) of torque. Similarly, the twin-turbo Z32s have 300 hp (220 kW) and 283 lb·ft (384 N·m) torque versus the single turbo Z31, which has 200-205 hp and 227 lb·ft (308 N·m) of torque. The Z32's twin turbo motor is also intercooled unlike the Z31 turbo. The Z31's single overhead cam engine has 13 head bolts per head, for a total of 26, where as the Z32's dualoverhead cam engine only has 8 head bolts per head, for a total of 16.
The Z31 chassis was designed after the previous Z-car, the Nissan 280ZX, and had two special editions based on it. The 50th Anniversary Edition focused on luxury to celebrate the company's semi-centennial in 1984, while the Shiro Special, released 4 years later, boasted performance-oriented upgrades.[2][3][4]Styling would becompletely redesigned with the release of the Z32, tending towards a wider footprint and more rounded curves with an overall result that the Z32 turned in a drag coefficient of .31 compared to the early Z31's .30. The newer chassis also featured hydraulic rear wheel steering called Super HICAS (in 1994 changed to an electric actuator), in its top-of-the-line models. Although it was not a specialedition, in 1996 Nissan designated the final 300 American units the Commemorative Edition. Production of the Z32 ceased outside of the home market and continued in Japan until August 2000.[5]
True to its heritage, the race-only 300ZX cars had several notable victories, including the 1986 Trans Am series and the 1994 24 Hours of Daytona. However, auto sports politics and a controversial GTS-1class win at the 24 Hours of LeMans that same year[6] prompted the International Motor Sports Association to declare the twin turbo engine illegal for future competition.[7] The 300ZX also holds the E/BMS land speed record of 419.84 km/h (260.87 mph) from the 1991 Bonneville Speed Trial.[8]
Throughout its life, the Z32 300ZX has been praised by critics. Car and Driver placed the car on its TenBest list for 7 consecutive years and Motor Trend awarded it as the 1990 Import Car of the Year.[citation needed]
The 300ZX was replaced by the Nissan 350Z(Z33) in 2003.
The Z31 chassis designation was first introduced in 1983 as a 1984 Nissan/Datsun 300ZX (the hatch lid had both a Datsun badge and a Nissan badge) in the US only. The 300ZX, as its predecessors, was known as a Nissan in other partsof the world. This continued in the US until 1985 model year when Nissan standardized their brand name worldwide and dropped the Datsun badge. A note can be made that all publications for the Z31 chassis 300ZX and its predecessors were copyright Nissan North America. Designed by Kazumasu Takagi and his team of developers, the 300ZX improved aerodynamics and increased power when compared to its...
