In the first years of its existence, the VAZ plant produced cars of the so-called "classic" scheme. The first generation of the "classic" was based on elements of the external design of the Fiat 124, and after only a few years after the start of production, it looked already outdated. This was especially noticeable in export markets.

The second generation of "classics"

The creation of a completely new model was unrealistic, since the plant and the state did not have the funds to fully re-equip the welding and assembly lines. Under these conditions, the optimal solution was the creation of a car with a power frame from the previous model and new details of the external body kit. The VAZ-2105, which went on sale in 1979, became just such a car. When exported to capitalist countries, the car was designated as Lada Nova Junior.

Motor 1300 and 1200

To reduce noise and improve other technical characteristics, a modernized engine with 1298 cc cylinders was used on the VAZ-21051 version. see. The main innovation in the design of the 69-horsepower engine was the camshaft drive, made by a flexible belt. This decision made it possible to reduce the weight of the VAZ-2105 engine andSimplify maintenance and service. The motor was supplied only with a four-speed gearbox, and they were produced in ever-decreasing numbers until 1994.

The basic version of the motor made it possible to fully realize the technical characteristics of the VAZ-2105, but the model range was expanded by using engines of a smaller cubic capacity. Cars equipped with a 1.2-liter power unit and a four-speed gearbox received the designation VAZ-21050. The release of such a 64-horsepower version was discontinued in early 1994. Engines 1197 and 1298 cubes were equipped exclusively with a carburetor power system.

Motor 1500 and 1600

A further increase in the technical characteristics of the VAZ-2105 was achieved by using a one and a half liter 77-horsepower engine from the third model. It is this version of the fifth model (under the index 21053) that has become the most common. Early cars came with a four-speed gearbox, later "fives" began to use a modernized gearbox with a fifth overdrive. Engines of 1.5 and 1.6 liters subsequently received a more modern power supply system from the injector. VAZ-2105 with a conventional carburetor system lasted on the assembly line until 2006.

Based on the block of this engine, a 50-horsepower diesel unit was produced in Barnaul, equipped with a five-speed gearbox. The technical characteristics of the VAZ-2105 with such an engine turned out to be very controversial - with low fuel consumption, the car had a very sluggishdynamics. The release of the VAZ-21055 (the model had such a designation) lasted only six years and ended in 2004. The machine did not receive distribution.

The "fives" with the most powerful 80 or 82-horsepower engine from the VAZ-2106 with a volume of almost 1.6 liters have become slightly widespread. This option was designated VAZ-21054 and was supplied only with a five-speed gearbox. Due to good dynamic data, these machines were willingly used by various law enforcement structures.

Injection versions

In the second half of the 90s, a gasoline supply system was first installed on a one and a half liter engine using injection through nozzles, which slightly increased the technical characteristics of the VAZ-2105. Mass injection began to be used only after 10 years. Such a system made it possible to maintain the most favorable ratio of the components of the working mixture, significantly reducing the amount of harmful emissions. The installation of an injector on VAZ-2105 vehicles entailed the use of special converters that burnt out harmful components in the exhaust gases. Some garage builders install their own injection on early release engines (including 1197cc engines).

Rotary motor

Since 1992, the most powerful “five” 21059 has been produced in small series, equipped with a rotary 1.7-liter two-section VAZ-4132 engine. This motor developed up to 140 forces, which is more than twice the performance of conventional VAZ-2105 engines. The rotary motor was installed only complete with a five-speed gearboxgears. A standard carburetor was used to power the engine.
