experimental or future models Index designations Each model has an internal index that reflects the level of modifications, based on the engine and other options installed. For example, the VAZ-21103 variant has the 1.5 L 16V engine, while the VAZ-21104 uses the latest 1.6 L 16V fuel injection engine. Since 2001, trim levels are also indicated by including a number after the main index: '-00' means base trim level, '-01' means standard trim and '-02' designates deluxe version; for example, VAZ-21121-02 means Lada 112 hatchback with a 1.6L SOHC engine and deluxe trim. The car's name is formed from 'VAZ-index model name. The classic Fiat 124-derived models were known on the domestic market as Zhiguli (Жигули) until the late-1990s, when the name was dropped; thus, the 2104-2107 range, as well as 110-series, actually lack a model name. The restyled Sputnik range was renamed Samara, but the Niva and the Oka retained their names. By the 2000s (decade), the VAZ designation was dropped from market names in favour of Lada and simplified export naming conventions were adopted, so VAZ-2104 effectively became Lada 2104, VAZ-2110 became Lada 110, VAZ-2114 became Lada Samara hatchback or Lada 114 and so on, though model indices continue to be used in both technical and marketing materials. The model names varied from market to market and as such should not be used except to indicate a certain export market. Instead, it is advisable to refer solely to the model number as these are the same for all markets.
