Mazda MX-5

The Mazda MX-5, also known as Miata (pronounced /miːˈɑːɾə/) in North America and Roadster (pronounced [ɺ̠oːdosɯtaː]) in Japan, is a two-seater roadster sports car built by Mazda in Hiroshima, Japan – introduced in 1989 and now in its third generation.

According to a 2003 Edmunds.com article, "the Miata deserves credit not only for reviving a dormant passion for roadsters, but for emboldening other manufacturers."[1]

Generations and overview

Now in its third generation, the MX5's first generation, the NA, sold over 400,000 units from 1989 to 1997 – with a 1.6L (98cuin) straight-4 engine to 1993, a 1.8L (110cuin) engine thereafter (with a de-tuned 1.6 as a budget option in some markets) – recognizable by its pop-up headlights. The second generation (NB) was introduced in 1998 with a slight increase in engine power; it can be recognized by the fixed headlights, and the glass rear window. The third generation (NC) was introduced in 2005 with a 2.0L (120cuin) engine.

The MX-5 was conceived as an elemental small roadster – with light weight and minimal mechanical complexity limited only by legal and safety requirements; technologically modern, but a philosophically direct descendant of the small British roadsters of the 1960s such as the Triumph Spitfire, Austin-Healey Sprite, MG Midget and Lotus Elan.

The MX-5 was designed with a traditional front-engine, rear-wheel drive layout and four-wheel independent double wishbone suspension. It has a longitudinally-mounted four cylinder engine coupled to a manual transmission (5 speed for NA, 5 or 6 speed in NB & NC); an automatic transmission is a cost option.

The body is a conventional, but light, unibody or monocoque construction, with a (detachable) rear subframe. The MX-5 also incorporates a truss marketed as the Powerplant Frame (PPF) which connects the engine to the differential, minimizing flex and contributing to responsive handling. Many MX-5s feature limited slip differentials and anti-lock braking system. Traction control is an option available on NC models. The earlier cars weighed in at just over a ton, with engine power output usually 120bhp (89kW). The later cars were heavier, with higher power engines.
