the result of a longer wheelbase and a slightly taller design, in a package retaining the length and width of the previous model. Another piece of equipment for comfort was the Active Noise Cancellation (ANC) system available in domestic market Hardtop models. This was the first installation of such a system, although its effect was limited and it was to be another twenty years before it reached wider adoption. Several Japanese models included an All Wheel Drive version (ATTESA). The engines used in the Japanese models ranged greatly in capacity and type. The SSS Attesa LTD model used a "redtop" SR20DET with . This was a similar engine/drivetrain package to the more powerful one used in the Pulsar GTi-R. It had only a single throttle body as opposed the GTi-R's multiple throttle body, smaller bearings, hydraulic rather than solid lifters, and a smaller turbo. The GTi-R had a large top mount intercooler, while the SSS ATTESA LTD had a smaller front mount intercooler. The Bluebird SSS was set apart from the North American Altima in that not only having the SR20DET and AWD Attesa as an option, it also had other details such as power folding retracting mirrors (some heated) and a rear wiper if equipped with a spoiler. US cars are also larger due to the fitment of bigger bumpers. Export markets The Australian delivered U13 Bluebird was released in late 1993 and terminated in 1997. Series 1 ran from 1993 until 1995 while Series 2 ran from 1995 to 1997. Series 2 saw the addition of a driver's airbag, revised grille styling, and a seat belt warning light. The Series 1 LX model came equipped with cruise control standard but strangely it was an option on the Series 2. The Australian U13 Bluebirds were available in three different models, LX—the base model but very well equipped, Ti—the luxury model, and the SSS—the sports model. Compared to the LX, the Ti had climate control, a sunroof, woodgrain styling, and gear selector display on the instrument cluster (automatic models only). while comparing the LX to the SSS, the SSS had a HUD (heads-up display—digital speedo on windscreen), climate control, fog lights, ski-port, woodgrain styling, and gear selector display on the instrument cluster (automatic models only). Despite there being a sports model (SSS), the LX was the fastest of the Australian models due to having the least weight. The engine used
