History

Ten years after completion of the development model of Skoda 1000 MB AZNP in preparing a new model car. Given the financial situation in the former centralized economy to industrialization of Slovakia not to leave enough money for the development of completely new car model. Although the model was 1000 megabytes at the time of its launch regarded as a modern car, experience has shown that the concept of rear drive is a dead end. Lack of funding, however AZNP decided that issue by upgrading the Skoda 100th The first prototypes of the new model was a mere facelift of the old model with angular bodywork (the prototype of the Škoda 727 1971). Later development department decided to address targeted problems with the rear of the engine cooling by shifting the condenser in front of the car. This has created a unique concept 1.2-liter and 13 liter engine cooling system. Positive influence elections ahead imposed cooler was better weight distribution and axle load. Type 742 was introduced in 1976 at the International Engineering Fair in Brno.

In 1981 the plant began production in Kvasiny coupé based on Škoda Garde Škoda 120LS car, which was the successor of the popular coupe Škoda 110 R Coupé. In 1984 was derived from the model Garde Rapid model.

Later, in 1984 passed the full lineup upgrade (known as Type 742 - M). Part of the modernization of the front and rear facelift mask body extending front and rear axles, which contributed to greater stability and the car was introduced rack management, the increased steering precision. The introduction of comb management require the use of new disks with calibrated center hole. All models are equipped with lighter plastic bumpers. With the advent of upgraded models, the unified front end look for cars Skoda 105, all of which were oval headlights and the Skoda 120 cars were designed new shape headlights. In parallel with the aging 1984 model was introduced to an innovative model derived from the Skoda 130 Skoda 120, which boasted over older models 5-speed gearbox, an engine with improved performance and modified brake system with higher performance.

In 1987 he was at the International Engineering Fair presented Skoda Favorit model, which heralded the end of the concept car with rear drive. Due to expectations of a new model of demand fell sharply and the old cars that caused the launch of the Škoda 120LX, 125, which contained some elements of the modern family car Skoda 130th Production of Škoda 742 model was finally completed in 1990.

Although the concept of the rear drive was at the time of putting this car on the market in Western Europe already obsolete and used only in rare cases, its use in the car provide some benefits.

Škoda 742.12

The motorization has been offered as a stronger alternative to ordinary consumers. It was a motor with a cylinder capacity 1174 cm ³.

Skoda 742.12X (LS, LX, GLS)

For the sporty models of type series 742 engine was offered 742.12X. It was the engine with a capacity of 742.12 consistent with the engine, but modifications piston crown to achieve a higher compression ratio. From 1976 to 1983 were the engines fitted 742.12X sharper and different camshafts. The presence of this engine in a car marked the letter S, or X in the model designation, if it was the 120th model Engine performance characteristics:

Gears

During production of this car were available four different gearbox fitted to these vehicles. All gear is conceptually based on the transmission of the Škoda 100th Initial models were identical with gear transmissions last Škoda 100 models, that have 4 degrees forward and one backward. In 1984 a production line was seeded 5-speed gearbox. Transmissions are mutually differed also used a permanent transfer.

4-speed manual transmission, 4.44 axle ratio

It is the oldest available transmission model range 742nd In the early years of production are assembled as a serial transmission to all Škoda 105/120 models. She was later replaced by 4-speed transmission with 4.22 axle ratio and the gearbox has become part of the equipment so as to desire. mountain gear. This transmission is standard fitted with a swinging axis. The gears were graded as follows:

• I. grade: 3.8
• II. Grade: 2.12
• III. Grade: 1.41
• IV. degree: 0.96
• reverse: 3.27
• axle axle ratio: 4.44

4-speed manual transmission, 4.22 axle ratio

This transmission later replaced the Type 742 the previous transmission. The reason was the subsequent introduction of 13-inch tires. The gearbox is identically graded, only different axle ratio. Series, this gearbox fitted as the swing-axles, so the swing-axle driveshaft.

4-speed manual transmission, axle ratio 3.9

This type of gear is mounted in a special Škoda 120L. This car should increase economy driving especially on roads first Class and highways, which allow a car traveling at the same speed at lower speeds, which had an impact on consumption. Skoda 120L in which the transmission was fitted was swinging axles.

5-speed manual transmission, axle ratio 3.9

For the new model range was introduced Škoda 130 5-speed manual gearbox, which, however, in an effort to increase predávanosti model Škoda 105/120 series got into the car and downgraded. When it is used in the model was mounted on a 125L swinging axles.

• I. grade: 3.8
• II. Grade: 2.12
• III. Grade: 1.41
• IV. degree: 1.08
• V. degree: 0.96
• reverse: 3.27
• permanent transfer Axle: 3.9

Internal trim
