Infiniti M30

One of the coolest features of the Infiniti M30 was the Sonar Suspension system that was also installed on the Maxima. It featured a sensor that would scan the road surface and adjusted the suspension accordingly via actuators mounted on the strut towers. There was also a switch on the center console that allowed the driver to change between "Sport" and "Comfort" settings, which were essentially "firm" and "soft", respectively. Sports cars tend to have firm, stiff suspensions that trade ride quality for handling, while luxury cars have a softer suspension to smooth out the ride being that they are less likely to need sharp handling. Unfortunately Infiniti was trying to have the M30 play two roles at once, and instead of performing one role superbly it performed two roles in a mediocre manner. The "Sport" setting isn't quite firm enough, while the "Comfort" setting was perhaps too soft. Additionally, it was sort of odd that the M30 had no factory options, so dealers offered the addition of a cellular phone and a CD player/changer. The sole engine was the VG30E, a 3.0 L SOHC V6 that produced 162 hp and was also used by many previous Nissan models such as the Maxima and the 300ZX. Like the 300ZX, the M30 was a front-engine and rear-wheel drive vehicle. The transmission was the RE4R01A, a four-speed automatic with electronic overdrive and the differential was a Nissan R200-type open differential. It is generally regarded among M30 enthusiasts that the change of engine, weak suspension and the lack of options in these categories was a serious mistake on Infiniti's part, and perhaps to blame for the lackluster sales. The M30 has a stock weight of 3400 lb (1540 kg), yet only 162 hp, creating an inadequate power to weight ratio for the intended image of a sports coupe. In addition, sports cars normally come with a manual transmission standard and have the option of an automatic. Instead, Infiniti didn't even give potential buyers the choice, as all M30s had a four-speed automatic. More or less, they did about everything wrong.
