:(詳細はsports car applied in non-Japanese markets to the "Z31" and "Z32" generations of the Nissan Z that were manufactured from 1983 to 2000. As with all other generations of this platform, these cars were marketed in the Japanese domestic market as the Fairlady Z. Sold on the Japanese market exclusively at ''Nissan Bluebird Store'' locations from 1983 through 2000 and in the United States from 1984 through 1996, the 300ZX name followed the numerical convention initiated with the Nissan S30 that was marketed in the U.S. as the 240Z, as suggested by Yutaka Katayama. The "X" designation had debuted with the previous generation Z car, the 280ZX, to signify the presence of luxury and comfort oriented features. The Z31 model of 1983 through 1989 was the more popular model, with over 100,000 more units sold than the later Z32. The Z31 continued the old S30 market positioning as a mid-priced sports car, but the target market for the Z32 generation changed by having a higher price and with consecutive increases each model year. ''Car and Driver'' placed the Z32 on its Ten Best list for 7 consecutive years, each model year of its availability in the United States. ''Motor Trend'' awarded it as the 1990 Import Car of the Year.〔(【引用サイトリンク】title=Motor Trend Import Cars of the Year Complete Winners List )〕 The Nissan 350Z, officially the Z33 generation Z-Car, succeeded the 300ZX in 2003. ==Z31== | length = | width = | height = | body_style = | weight = | aka = Nissan Z31 | predecessor = Nissan 280ZX | designer = Kazumasu Takagi〔 (1982) }} The Z31 chassis designation was first introduced in 1983 as a 1984 Nissan/Datsun 300ZX (the hatch lid had both a Datsun and a Nissan badge) in the U.S. market. The 300ZX, as its predecessors, was known as a Nissan in other parts of the world. This continued in the U.S. until 1985 model year when Nissan standardized their brand name worldwide and dropped the Datsun badge. 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 predecessor, the 280ZX. The newer Z-car had a drag coefficient of 0.30 and was powered by Japan's first mass-produced V6 engine instead of an inline 6. According to Nissan, the V6 engine was supposed to re-create the spirit of the original Fairlady Z.〔 The Z31 generation featured five engine options. A turbocharged dual over head cam 2.0 L straight-six (RB20DET, used in the 200ZR), a turbocharged single over head cam 2.0 L V6 (VG20ET, found in 200Z/ZS/ZG), a naturally aspirated single over head cam 3.0 L V6 (VG30E, found in 300ZX), a turbocharged single over head cam 3.0 L V6 (VG30ET, used in 300ZX Turbo) and a naturally aspirated dual over head cam 3.0 L V6 (VG30DE, used in 300ZR). The Z32 had a naturally aspirated dual over head cam 3.0 L V6 (VG30DE) or a twin turbocharged dual over head cam 3.0 L V6 (VG30DETT). The Z31 and Z32 had electronic fuel injection (EFI), and were rear wheel drive. They were available in either left or right hand drive. Two Special Edition versions of the Z31 generation model were produced; a 50th Anniversary Edition celebrated the company's semi-centennial in 1984 and offered additional luxury features, and a "Shiro Special", released four years later, with performance-oriented upgrades.〔(【引用サイトリンク】title=Nissan 300ZX - Z31 )〕〔(【引用サイトリンク】title=US 1988 300ZX SS Registry and Information )〕〔(【引用サイトリンク】title=The US 300ZX Production Numbers )〕 Unlike its predecessors, the Z31 featured a V6 engine in the 200Z/ZS/ZG, 300ZX and 300ZR, and the only Z31 to come with an Inline 6 cylinder engine was the Fairlady 200ZR which was only available in Japan. The new V6 (2960 cc) Single overhead cam engine was available as a naturally aspirated VG30E or a turbocharged VG30ET producing and respectively. The engine was either a type A or type B sub-designation from 1984 to March 1987, while models from April 1987 to 1989 had a W sub-designation. The W-series engines featured redesigned water jackets for additional cooling, and fully floating piston wrist pins. The 1984 to 1987 turbo models featured a Garrett T3 turbocharger with a 7.8:1 compression ratio, whereas 1988 to 1989 models featured a low inertia T25 turbocharger with an increased 8.3:1 compression ratio and slightly more power—165 hp naturally aspirated and turbocharged. Finally, these engines were equipped with self-adjusting hydraulic valve lifters. The transmissions were a 5-speed manual or an optional 4-speed automatic (all Z31 automatics were the E4N71B equipped with torque-converter lockup INCLUDING turbo models.) All Z31s were equipped with a Nissan R200 rear differential, April 1987 and later turbo models received an R200 clutch limited-slip differential except 1988 Shiro Specials which had a Viscous-type limited slip. There were three trim models available: SF, GL and GLL. The SF model was only available in Canada. Similar to Chrysler's electronic voice alert, the 1984-1986 Z31 GL and GLL models featured a voice warning system which warned drivers of the following: 1) Doors left ajar while in motion "Right/Left Door is open", 2) Parking Brake engaged while in motion "Parking Brake is on", and 3) Fuel Levels is low at 2 7/8th gallons remaining "Fuel Level is Low". The voice is a female voice. In racing trim, the 300ZX achieved several victories, including wins in the 1986 Trans Am series and 1994 24 Hours of Daytona. However, auto sports politics and a GTS-1 class win at the 24 Hours of Le Mans that same year〔(【引用サイトリンク】title=24 h Le Mans )〕 prompted the International Motor Sports Association to declare the twin turbo engine illegal for future competition. The 300ZX also holds the E/BMS land speed record of 419.84 km/h (260.87 mph) from the 1991 Bonneville Speed Trial. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Nissan 300ZX」の詳細全文を読む スポンサード リンク
