MX-5 Miata

The Journalist Who Talked His Way Into Building a Sports Car

In 1976, Bob Hall was an American motoring journalist working for Motor Trend. He was fluent in Japanese, obsessed with small British roadsters, and, as it happened, sitting across a table from Mazda R&D chief Gai Arai and a rising engineering executive named Kenichi Yamamoto. Asked what kind of car Mazda should build next, Hall gave an answer that stuck: the simple, bugs-in-the-teeth, wind-in-the-hair British sports car, he said, no longer existed, and somebody ought to build a modern one. It was a magazine writer's opinion, not a business plan, and for five years it went nowhere. Then in 1981 Yamamoto, on a visit to the United States, turned to Hall and asked him directly to study his own idea. Hall had by then joined Mazda's product-planning staff in California, and in early 1982 he submitted a position paper proposing a lightweight two-seater built, wherever possible, from parts Mazda already had on the shelf to keep cost and risk down: an existing four-cylinder engine, a manual gearbox, a rear axle, even a shared floorpan. Hall is often called the "father of the Miata," a title he has pushed back on, since the car that reached showrooms in 1989 was the work of a large team of American and Japanese engineers and designers, not one person's sketch.

What that team built was deliberately unfashionable for its moment. By the early 1980s the traditional roadster format of front engine, rear drive, manual top and minimal weight had all but disappeared from new-car showrooms, squeezed out by front-wheel-drive hatchbacks and rising safety and emissions costs. Mazda's engineers, working under the project name that became the Lightweight Sports (LWS) concept, chose a live rear axle and double-wishbone suspension at both ends, a naturally aspirated 1.6-liter four making a modest 116 horsepower, and a kerb weight that stayed well under a ton and a half. Nothing about the numbers was exotic. The car's appeal was the way those unremarkable parts were tuned together. Mazda's engineers later distilled that philosophy into the Japanese phrase jinba ittai, horse and rider as one. Mazda unveiled the finished car, given the internal code NA, at the Chicago Auto Show on February 10, 1989, priced at roughly $14,000, and put it on sale in the United States and Canada that May as a 1990 model, with Japanese deliveries following in September and European sales arriving in 1990.

The response caught even Mazda by surprise. The MX-5, badged Miata in North America and Eunos Roadster in parts of Japan for a period, sold well past its factory's expectations through the early 1990s, at a moment when almost no other manufacturer offered anything like it. Mazda kept the first generation in production through 1997, refining it with a stiffer chassis, a limited-slip differential, and eventually a 1.8-liter engine option, before replacing it with the NB generation in 1998. The NB kept the same basic recipe, with pop-up headlamps gone, chassis mildly stiffened, and, from 2001, a factory turbocharged Mazdaspeed variant for the Japanese market. It ran through 2005. The third generation, NC, arrived for the 2006 model year noticeably larger and heavier than its predecessors, and in 2007 added a power-retractable hardtop (PRHT) alongside the folding soft top, the first factory power hardtop in the model's history. Mazda held the NC in production until 2015, when the fourth generation, ND, replaced it. The ND was deliberately re-shrunk and lightened relative to the NC, built on Mazda's SkyActiv architecture and offered, from the 2017 model year, in a retractable fastback (RF) body alongside the soft-top convertible. Production of the ND has continued at Mazda's Hiroshima plant since March 2015 and remains current as of this writing.

What makes the MX-5's story unusually well documented, in production terms, is that Mazda itself began treating cumulative output as a marketing milestone almost from the start. Guinness World Records first certified the MX-5 as the world's best-selling two-seat sports car when cumulative production reached 531,890 units in May 2000, and Mazda secured updated certifications as the total passed 700,000, then 800,000, then 900,000 units. That last mark, announced by Mazda on February 4, 2011, was reached twenty-one years and ten months after mass production began at Ujina Plant No. 1 in Hiroshima in April 1989. Mazda built the one-millionth MX-5 on April 22, 2016, and announced the milestone two days later; Mazda USA's model history gives well over 1.2 million units by the time of Mazda's 2023 Japan Mobility Show appearances.

Racing followed the road car almost immediately, though mostly as grassroots and club competition rather than a factory works program in the way Mazda ran its rotary prototypes. Mazda and SCCA-affiliated organizers built spec racing series directly around the car: Spec Miata in North America and equivalent one-make and showroom-stock classes elsewhere. That turned the MX-5 into one of the most raced amateur circuit cars in the world, precisely because its low cost, predictable handling, and huge parts supply made it a durable choice long after flashier rivals had become impractical to campaign. Mazda later formalized a factory-supported MX-5 Cup series in the United States, feeding the same low-cost, close-racing identity back into a semi-professional ladder series.

Cultural reception followed a similar arc from novelty to institution. Automotive journalists in 1989 tended to frame the MX-5 as an act of restoration, Mazda giving buyers back something the established manufacturers had let lapse. The tone of the motoring press barely changed across three subsequent redesigns, an unusual consistency for a car sold across four decades. Owners' clubs, one-make race series, and a genuinely global enthusiast culture all trace back to the same original decision: build a small, light, uncomplicated sports car and refuse to let it grow much beyond that brief, even as the rest of the industry added weight, complexity, and size to nearly everything else in the showroom. Whether that discipline can be credited to any one person is exactly the question Bob Hall has spent decades deflecting. The paper trail runs from his 1976 conversation and 1982 position paper through a Mazda product-planning and engineering team on both sides of the Pacific, and the car that resulted has outlasted every one of its original doubters, including, by his own account, Hall himself.

Mazda's own production milestones (531,890 by 2000, 900,000 by 2011, one million by 2016) count the whole nameplate and do not break out single generations. Wikipedia gives roughly 291,000 NB-generation cars built between 1998 and 2005, and evo gives nearly 230,000 NC-generation cars built between 2005 and 2015.

The Studio That Gave the Miata Its Shape

Bob Hall's position paper set the brief, but the car's actual form came out of Mazda's small North American design studio in Irvine, California, under a Japanese-born designer named Tsutomu "Tom" Matano. Matano joined Mazda in December 1983 as chief designer of a facility that then employed fewer than ten people, after earlier stints at General Motors and BMW, and led the studio's production design work on what became the NA-generation Miata. Matano's team organized its work around a philosophy it called "Romantic Engineering and Inspired Sensation Design" and held that a car's engineering should serve an emotional response rather than the other way around. The original Miata was the first Mazda product built to that brief. On the engineering side, the same discipline was distilled into a short Japanese phrase, jinba ittai, horse and rider as one, which Mazda's program manager Toshihiko Hirai gave the development team as a working mantra rather than a marketing slogan; engineers on every subsequent generation have cited it as the standard against which weight, steering feel, and seating position were checked. Matano died on 21 September 2025, at age 77; obituaries from his alma mater, ArtCenter College of Design, and from the automotive press credited him with turning Hall's idea and Yamamoto's institutional backing into an actual, driveable car, even as Matano himself, like Hall, resisted being cast as the Miata's sole author.

Still on the Grid, Still in the Game

The MX-5's presence outside dealerships and racetracks has been almost as durable as its production run. Mazda has kept a version of the car in the Gran Turismo console racing series since the franchise's earliest installments, and has continued adding new variants, including in September 2025, when Mazda's Japan-only Miata MX-5 Spirit Racing Roadster 12R, a 200-horsepower one-make racer, was added to Gran Turismo 7 in the game's Update 1.63. That kind of sustained presence in a single racing-simulation franchise across three decades is unusual for any nameplate, and it echoes the same real-world one-make racing culture (Spec Miata and the factory MX-5 Cup) that has made the car one of the most raced amateur circuit cars in the world.
