The Mazda MX-6 was a front-wheel drive sporty coupé produced by Mazda between 1987 and 1997. It was called the Mazda Capella in Japan until 2002 before being renamed Mazda Atenza/Mazda6.

The MX-6 was mechanically identical to the Mazda 626 and subsequently the Ford Probe. These cars shared the GD (1988-1992) and GE (1993-1997) platforms. The MX-6 replaced the 626 Coupé, although it continued to share the same chassis. Mazda shared the GD and GE chassis with Ford for their own Probe. The MX-6, 626 and Ford Probe were made together in joint-venture plants either by AutoAlliance in Flat Rock, MI for the North American market, and by Mazda Japan for Asian and European Markets.

The first generation MX-6 appeared in 1988 and lasted until 1992 in the United States. In some markets the model years were from 1987 to 1991. It was based on a series of futuristic sports compact concept cars of the early 1980s. It was a large coupé, based on the Mazda GD platform, and was powered by the I4 Mazda F engines.

The US market made use of the F2 2.2L engine, with the base engine produced 110hp (82kW), but a 145hp (108kW) turbocharged version was available. European and Japanese market versions were shipped with either the F8 1.8L, FE 2.0L or FE-DOHC 2.0L DOHC engines.

The MX-6 was produced with two transmission options, a 5-speed manual transmission or a 4-speed automatic with overdrive. The MX-6 was also known to be a very reliable car, mechanically.

This generation was available in several trim levels, which differ depending on the market the vehicle was sold in. In the United States, the MX-6 was available in DX, LX, LE, and GT trim levels:
