First Generation 1.8L Miatas: 1994-1997

For the 1994 model year, the first-generation MX-5 was freshened with the introduction of the more powerful 1.8 L (110 cu in) BP-ZE engine, dual airbags and a limited slip differential in some markets.

The chassis was substantially braced to meet new side-impact standards, most visibly by adding a "track bar" between the seatbelt towers inside the car, but also to the front and rear subframes. Also, 1994 and 1995 were the only years in which Mazda offered a light metallic blue paint (Laguna Blue Mica), making these cars rare collectors cars to some.

1994 also saw the introduction of the "R" package, a sport-themed package with Bilstein shocks and subtle underbody spoilers, in addition to the removal of unnecessary items such as power steering. No body style changes were made, though.

The new 1.8 L (110 cu in) engine produced 98 kW (131 bhp), which was then increased by 1 kW (1.3 bhp) for the 1996 model year. The base weight increased to 990 kg (2,200 lb). Performance was improved slightly, the additional power being partly offset by the extra weight.
