Mazda MX-5 - Generations and Overview

Generations and Overview

The MX5's first generation, the NA, sold over 400,000 units from 1989 to 1997 – with a 1.6 L (98 cu in) straight-4 engine to 1993, a 1.8 L (110 cu in) 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, although first generation owners may opt for the glass window design when replacing the original top. The third generation (NC) was introduced in 2005 with a 2.0 L (120 cu in) engine.

It was launched at a time when production of small roadsters had almost completely ceased. The Alfa Romeo Spider was the only comparable volume model in production at the time of the MX-5's launch. Just a decade earlier, a whole host of similar models — notably the MG B, Triumph TR7, Triumph Spitfire and Fiat Spider — had been available.

The body is a conventional, but light, unibody or monocoque construction, with (detachable) front and rear subframes. 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. Some 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 116 bhp (87 kW). The later cars were heavier, with higher power engines.

With an approximate 50:50 front/rear weight balance, the car has nearly neutral handling. Inducing oversteer is easy and very controllable, thus making the MX-5 a popular choice for amateur and stock racing, including, in the US, the Sports Car Club of America's Solo2 autocross and Spec Miata race series, and in the UK, the Ma5da racing championship.

The MX-5 has won many awards including Wheels Magazine 's Car of the Year for 1989 and 2005; Sports Car International's "best sports car of the 1990s" and "ten best sports cars of all time"; 2005–2006 Car of the Year Japan; and 2005 Australian Car of the Year. The Miata has also made Car and Driver magazine's annual Ten Best list 11 times. In their December 2009 issue, Grassroots Motorsports magazine named the Miata as the most important sports car built during the previous 25 years.

In 2009, English automotive critic Jeremy Clarkson wrote:

The car remains popular in the UK, with over 100,000 MX-5s registered as of June 2011.
