Ẽfini

In the late 1980s, Mazda diversified in the Japan market with the launch of three new marques. The company created Autozam, Eunos, and Ẽfini, in addition to the Mazda and Ford brands already marketed there. This experiment was ended in the mid-1990s.

The Ẽfini name and logo originated in several limited-edition RX-7s from the late 1980s. As a brand, it encompassed most, if not all dealers formerly under Mazda's "Auto" dealer chain.

The Ẽfini marque was a sport-oriented brand, as opposed to the more comfortable, luxury-oriented Eunos. Today, Mazda continues to use the Ẽfini name as one of the company's dealership chains, along with Autozam, but the vehicles sold no longer use it. This included the following vehicles:
 * 1990-1997 Efini MPV/Mazda MPV
 * 1991-1993 Efini MS-6/Mazda Cronos
 * 1992-1997 Efini MS-8 car unique to the brand
 * 1991-1993 Efini MS-9/Mazda 929
 * 1991-1996 Efini RX-7/Mazda RX-7

Naming the marque
The name is actually written with a tilde over the initial E, and can therefore be assumed to be IPA, the pronunciation symbols universally taught in Japan, and quite often used in product naming. The accompanying katakana (アンフィニ) shows the intended pronunciation in Japanese. A Google search for combinations of 'Mazda' with various spellings shows the following list, in descending order of popularity: Mazda spells the name "Anfini" in official corporate publications, but other official sites use "Enfini" and "Efini", see for example Enfini-Aomori.
 * (8230 hits) 'Anfini': the normal (Hepburn) romanisation of the Japanese reading
 * (6170 hits) 'Efini': the IPA with the diacritic removed (most of these hits seem to be in Russian)
 * (1470 hits) 'Enfini': presumably a misspelling (or misguess) of the French, influenced by the 'E-tilde' of the IPA.
 * (956 hits) 'Infini': the presumed intended name.
 * (433 hits) 'Ifini': seen in New Zealand imports from Japan.
