Second generation (F31; 1986–1992)
Most of the information in this article was translated from the Nissan Leopard article on Japanese Wikipedia at ja:日産・レパード.
The F31 Leopard appeared in February 1986 and was only available as a luxury GT coupé. This vehicle shared a platform with the Nissan Skyline R31, Nissan Cefiro A31, and the Nissan Laurel C32 to share development costs, benefiting from Project 901. The Leopard sedan was replaced by the Nissan Bluebird Maxima in 1988.
The F31 Leopard was directly competing mainly with the Toyota Soarer, Mazda Cosmo, and the Honda Legend coupé in 1986. Whereas Toyota offered the Soarer several iterations of its straight six in 2.0, 2.8, and 3.0 liters' displacement, Nissan offered the all-new V6 either naturally aspirated or with a turbo in its Leopard. The displacements of the engines were of either 2.0 or 3.0 liters. The engines offered were the VG30DET, VG30DE, VG20DET, VG20ET, and VG20E. Early 2.0 turbo versions had the single-cam (per bank) VG20ET, but from August 1988, the quad-cam version appeared.
The bodywork was also facelifted in August 1988 and now featured a smoother front appearance, achieving a wind resistance coefficient of 0.32. It was the facelifted version that was exported to the USA, and approximately 12,000 Leopards were sold (with around 6,000 of those being converted to convertibles by ASC). In the USA, the F31 was called the Infiniti M30.[8] Output of the VG30DE engine also increased marginally at the time of the facelift. The new turbocharged 3.0 liter VG30DET engine was available in top-spec form, which produces 255 PS. Only the smaller VG20ET and VG20DET engines had intercoolers installed.
The companion fastback sports car, the Fairlady ZX, reflected the angular bodywork. Still, the coupé remained exclusive to the Nissan Store locations in Japan. The Leopard's more traditional coupé styling was offered as an alternative to the Fairlady ZX's fastback appearance.
Trim packages started with the top-level Ultima Grand Selection with the 3.0 V6 engine, the Ultima with the 3.0 V6 (later the Ultima received the 3.0 V6 turbo), the XS-II Grand Selection with the 2.0 V6 Turbo, the XS-II with the 2.0 V6 Turbo, the XS with the V6 Turbo, the XJ-II with a 2.0 V6 and the base model called the XJ with the 2.0 V6. All models came with a digital instrument cluster, all models except the XS and the XJ came with stereo and cruise control buttons installed in the steering wheel center pad, and both Grand Selection models were installed with a 6-inch CRT TV screen installed in the dashboard below the A/C controls that allowed passengers to watch broadcast TV if the transmission was in Park and the parking brake applied. The screen was not touch-sensitive and didn't offer a CD-ROM-based navigation system. The display also showed AM/FM stereo settings. The video entertainment system also had RCA connections to attach a camcorder and watch recorded video. Sony supplied the stereo and video equipment. On top of that, the Ultima models featured a keyless entry card.
The Leopard F31 had few factory options, but dealers offered the addition of a cellular phone installed in a dedicated compartment in the dashboard above the glove compartment, where a modern passenger-side airbag would now be located. They also offered a choice of a cassette tape changer installed in the center armrest compartment, with a separate single-disc CD player in the dashboard. A CD changer was later upgraded to the center armrest compartment.
Catering to Japanese tastes for luxury, the Leopard wasn't available in leather for all trim packages, with a wool interior offered on the top three trim packages. The front passenger seat was also equipped with what Nissan called the "Partner Comfort Seat," where the top portion of the front passenger seat was further articulated to tilt forward, supporting the passenger's shoulders while allowing the seatback structure to recline. The front edge of the passenger seat cushion was also adjustable. This was created by Dr. Yoshiyuki Matsuoka, who worked for Nissan from 1982.[9]
Like the Skyline and Fairlady ZX, the Leopard coupé was a front-engined and rear-wheel drive vehicle. The RE4R01A four-speed automatic with electronic overdrive was used, as well as a five-speed manual transmission, which was only available in the domestic Japanese market on the lower trim level XJ-II and the XJ 2.0 V6 without a turbo.[3] The differential was a Nissan R200-type open differential.
The suspension was shared with the Skyline and Laurel, using MacPherson struts for the front wheels and a semi-trailing arm rear suspension with coil springs for the rear. If the Leopard was optionally equipped with the "Super Sonic Suspension" system, a sonar module mounted under the front bumper scanned the road surface and adjusted the suspension accordingly via actuators mounted on all four coil over shock absorbers. There was also a switch on the center console that allowed the driver to change between "Auto," "Soft," "Medium," and "Hard" settings on all models except the XS model, which removed the "Auto" selection. The speed-sensitive rack-and-pinion power steering could also be separately reduced for a sporting feeling, and the suspension setting would modify both the steering feel and the shift points on the automatic transmission. A multi-link suspension was installed on the front wheels to accommodate the adjustable ride height shock absorbers.
The Leopard F31's production run lasted seven years, ending in June 1992 due to lagging sales. Seven years was very long by period Japanese standards, nearly equaling the runs of two generations of most Japanese cars.[3] Nobody knows exactly how many Infiniti M30 were produced for the US market, but it has been said that just over 17,000 were made. It is unknown how many were coupés and how many were convertibles; the convertible was only available in 1991 and 1992. 38,000 F31 Leopards were sold in Japan during its seven-year production span.[10]
