The article traces the development of engines for Tolyatti-built Zhiguli models, beginning with the decision to give the VAZ-2101 an overhead-cam engine rather than the older Fiat 124 layout. Changes to bore and piston stroke then produced a range of engine sizes, including the widely used 1.5-liter VAZ-2103 unit and larger engines for higher-end models.

Later variations included a timing-belt engine for some VAZ-2105 and 2107 versions, as well as export models with fuel injection. The article also recounts VAZ’s rotary-engine experiments and its diesel program, which led to roughly 6,000 diesel 2104 and 2105 cars being assembled in the early 2000s.
