 In 1993, the lengthened model of Niva appeared for the first time, known as VAZ-2129 and was being produced very briefly (only for about a year) due to which it is very rare and was also never exported.Although having a much longer wheelbase, it retained usual three doors like the basic hatchback model (it only featured additional square middle window added at the sides); however, in design it was actually a hybrid of old and new generations, since it featured the old VAZ-2121 (Niva 1600) body and interiors combined with new VAZ-21213 (Niva 1.7) 1680-cc engine and 5-speed transmission (although later, 1994 production models featured even new body and interiors).In 1995, the lengthened estate model with longer wheelbase and five-door appeared, originally known as the VAZ-2131 Niva; commercially, it has no difference in name than standard (three-door) model, which is why it is often referred simply as Niva five- door.
