Production of the 2105 VFTS started in 1979 at the Vilnius plant in Lithuania, later receiving Group B homologation in October of 1982 under the moniker “VFTS-2” (which simply meant that it was the second rally model to come out of the company). All of VFTS’ rally cars were reputed to be simple, easy to repair, and allowed for decent performance at an affordable price.
The 2105 VFTS rally car made use of the same 1568 cc engine that was developed for the firm’s first rally vehicle, the Lada 1600. The naturally aspirated unit could more than double its factory output to a healthy 160 BHP thanks to the use of double carburettors, modified internals, and 100-octane racing fuel. The small engine displacement would efficiently put the car in the B/10 class (for engines between 1300 and 1600 cc) where it was more than a match for any similar competition.
Improvements were made available over the course of its production such as a reinforced rear axle housing in 1985 and a new 5 speed transmission in 1986. An interesting particularity of the 5 speed gearbox was the shifting pattern with its first gear in the far right corner above reverse, while second through fourth occupied the normal pattern of a 4 speed unit. This layout was perfect for rallying since 1st gear is hardly ever selected and allowed the most used gears to be lined-up with each other rather than crossed. Other improvements included the availability of lighter aluminium inner door panels, hood/bonnet (with an added inlet duct), rear trunk/boot, and polycarbonate side screens.
The Lada 2105 VFTS competed in but a rare few World Rally Championship outings in the Group B era such as Finland’s 1000 Lakes Rally where it utterly dominated the B/10 class in 1986 by occupying the first 6 class positions. Russian rally driver Igor Bolshikh would finish 18th overall and first in class. However, the car was more competitive in Eastern Europe’s national events where it led most events and clinched an extensive list of podium finishes.
Production of the 2105 VFTS officially ended in 1990 with a total of 30 units built and sold around the world. The car was not affected by the infamous Group B ban since it competed in the B/10 class and continued to be widely used in rallies until the expiration of its homologation at the end of 1991.
The car had by then gained so much notoriety among rally enthusiasts of the old communist block that many privateers started to copy them and it soon became available as a kit car. Replicas still compete in various national rally club series to this day and is very popular in Hungary.
It is note to mention that VFTS also worked on the “Lada Turbo” Group B Prototype, better known as the Lada Samara EVA (click to learn more).

HOMOLOGATION / PRODUCTION VERSION
VAZ: Volzhsky Avtomobilny Zavod (now AvtoVAZ), is better known as Lada. The 2105, also known as the “Zhiguli”, was based on the Fiat 124 platform, and was introduced in 1979. Incredibly, the production of the model lasted until 2010. While it was obviously conceived as an economy car without any motorsport aspirations, the 2105 is still very popular among Russian and Eastern Europe’s automobile enthusiasts.
The VAZ 2105’s mass production far exceeded the 200 homologation units required by the Group B regulations. In such instances, the FISA/FIA could homologate a model for competition if presented with a limited series of minimum twenty “evolution” units, or cars equipped with the various VO (Variant Option) parts aimed at racing. This was the case for the VFTS.
Under normal circumstances, this would qualify the 2105 VFTS as being a genuine “evolution” (ET) model. Notwithstanding, the car received a normal Group B homologation on October 1st of 1982 (# B-222 / click to see papers).
The VFTS company is known to have produced 30 of these special cars during its production run from 1979 to 1990. It has been since widely copied by rally enthusiasts all over the world.
