 Interior was only minimally changed, along with some minor changes to the instrument panel, choke knob, and other details, probably the most notable differences are firstly in its VAZ-2106 steering wheel, which was now decorated with classic Russian ornaments featuring the Lada logo on its central (leather) part and slightly different leather pattern on seats.Those pre-1985 models are visually best recognizable by mentioned details and are today extremely rare (in preserved condition almost nonexistent anymore), so are very valued by collectors.The first generation (VAZ-2121 Niva, or Lada Niva 1600 as known commercially) was in production until 1993 (existing in parallel in production with new model until the end of the same year) when the new and more powerful (1.7-l, 80 horsepower) four-cylinder petrol engine (designed purposely for Niva, thus was not used by any other VAZ model until then) was introduced, replacing the previously used (1.6-l, 75-hp) VAZ-2106 engine and making the appearance of the new model (VAZ-21213/21214 or Lada Niva 1.7/1.7i), as was the carburetor replaced by single-point fuel injection supplied initially by General Motors on 21214/1.7i model and the usual Weber carburetor was replaced by improved Solex one on 21213/1.7 model.
