Chronology
SuccessorMazda MX-5 (NB)

The Mazda MX-5 (NA) (sold in Japan as the Eunos Roadster (ユーノス・ロードスター, Yūnosu Rōdosutā) and in North America as the Mazda MX-5 Miata) is the first generation of the Mazda MX-5, manufactured from 1989 to 1997. Inspired by the post-war era British sports cars, the MX-5 rejuvenated interest in roadsters after the demise of cars such as the MG B, Triumph Spitfire, and Fiat 124 Spider.

Since its debut, the MX-5 has won numerous automotive awards and has become the world's best selling sports car.[3]

Overview

[edit]

The MX-5 was unveiled at the Chicago Auto Show on February 10, 1989, with a price tag of US$14,000 (equivalent to $35,513 in 2024).[4] The MX-5, with production code NA, was made available for delivery to buyers worldwide in the following dates: May 1989 (as a 1990 model) in the US and Canada; September 1, 1989 in Japan; and 1990 in Europe. An optional hardtop was made available at the same time, in sheet moulding compound (SMC). Demand initially outstripped production, fueled by enthusiastic press reviews.

In Japan, the car was not badged as a Mazda, as the company was in the process of launching different marques for deluxe models, similar to Nissan's Infiniti, Honda's Acura and Toyota's Lexus. Instead, the Mazda MX-5 was sold as the Eunos Roadster, and was joined by the MX-3/AZ-3/Eunos Presso (based on Japanese Mazda dealerships). The exterior dimensions and the engine displacement were also in compliance with Japanese Government compact car regulation.

Mazda MX-5 with hardtop (Australia)

The NA has a steel unitary body-shell with a lightweight aluminium hood. Overall dimensions are 3,970 mm (156 in) in length, 1,675 mm (65.9 in) in width, and 1,235 mm (48.6 in) in height. Without options, the NA weighs only 980 kg (2,160 lb). It has a drag coefficient of Cd=0.38. Suspension is independent by double wishbones on all four wheels, with anti-roll bars front and rear. Four-wheel disc brakes, ventilated at the front, are behind alloy wheels with 185/60HR14 radial tires. The base model came with stamped steel wheels from the then-current 323/Protege.

1990 Mazda MX-5 1600cc DOHC 4-cylinder engine. This example has been modified with the addition of a GReddy TD04 (Mitsubishi) turbocharger kit.

The original MX-5, with standard manual transmission, came with a 1.6 L (98 cu in) DOHC inline four-cylinder engine, producing 86 kW (115 bhp) at 6,500 rpm, and 136 N⋅m (100 lbf⋅ft) of torque at 5,500 rpm. The engine employs an electronic fuel injection system using a vane-type air flow meter and an electronic ignition system with a camshaft angle sensor instead of a distributor.[5] This engine, codenamed B6ZE(RS), was specifically designed for the MX-5 and featured a lightened crankshaft, flywheel, and aluminium sump with cooling fins. An MX-5 with the optional automatic transmission had its 1.6L engine tuned to develop peak torque at lower rpm's (4000 rpm instead of 5500) to better mate with the automatic transmission gearing and torque requirements. This tuning resulted in a lower peak power of 78.5 kW (105 bhp) at 6500 rpm.[6]

The standard transmission was a 5-speed manual, derived from that used in the also rear-wheel drive Mazda 929/Luce.[7] The gear-shift was the subject of close attention during development, with engineers told to make it shift in as small a gear pattern as possible and with minimal effort.[8] In the American and Japanese markets, a 4-speed automatic transmission was also offered, as well as an optional viscous limited-slip differential on manual transmission cars. To achieve a low introductory price and low weight (true to Lotus' "add lightness" philosophy, applied on the Elan model), the entry model was kept basic. It had steel wheels, no power brakes, steering, or windows, and no stereo or air conditioning. Power brakes, steering, stereo, and air conditioning were added as standard equipment in later years, and depending on market.

Mazda reported that the 1990 NA would reach 0-60 mph (97 km/h) in 8.6 seconds, with a top speed of 116.8 mph (188.0 km/h).[9]: 79  Japanese market Eunos models were limited to 180 km/h (110 mph).[citation needed] Car and Driver tested the NA for their September 1989 issue, achieving a 0-60 mph (97 km/h) time of 9.2 seconds and a top speed of 116 mph (187 km/h), with hardtop installed.[2] Motor Trend's July 1989 test gave a 0-60 mph (97 km/h) time of 8.9 seconds.[10] The NA with an automatic transmission reached 97 km/h (60 mph) in 9.9 seconds and had a top speed of 181 km/h (112 mph).[11]

Interior

In 1993, 1,500 LE (Limited Edition) cars were produced. This model featured red leather interior, upgraded stereo, Nardi shift knob, Nardi steering wheel, cruise control, limited-slip differential, power windows, power mirrors, power steering, air conditioning, BBS wheels, Bilstein shocks, front and rear spoilers, ABS brakes, stainless sill plates, and Harley style peanut tank door speaker trim. All 1993 LE cars came in black.

For the 1994 model year, the first-generation MX-5 was freshened with the introduction of the more powerful 1,839 cc (1.8 L; 112.2 cu in) BP-ZE engine, dual airbags placed in a redesigned dashboard, the addition of a Mazda badge on the front fascia in the US and a Torsen 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 desirable to some collectors. 1994 also saw the introduction of the "R" package, a sport-themed package with Bilstein shocks, stiffer sway bars, retuned springs, subtle front and rear underbody spoilers, and a Torsen LSD. Air conditioning was optional, but the "R" package was not available with power steering, leather, or an automatic transmission. It can also be identified by a red Miata badge on the rear instead of the usual black. No body style changes were made, however. Halfway through the 1997 model year the hazard light button was changed to a black button with red symbol as opposed to the earlier red button with white symbol.

The new 1,839 cc (1.8 L; 112.2 cu in) engine produced 96 kW (129 bhp) at 6,500 rpm and 149 N⋅m (110 lbf⋅ft) of torque at 5,500 rpm,[12] which was then increased to 99 kW (133 bhp) at 6,500 rpm and 155 N⋅m (114 lbf⋅ft) of torque at 5,500 rpm for the 1996 model year.[13] The base weight increased to 990 kg (2,180 lb). Performance was thus improved slightly, because the additional weight was more than offset by the extra power. In some markets such as Europe, the 1.6 L (98 cu in) engine continued to be available as a lower-cost option, but was detuned to 66 kW (89 bhp). This lower-powered model did not receive all the additional chassis bracing of the new 1.8 L (110 cu in). Japanese and U.S. models offered an optional Torsen LSD, which was far more durable than the previous viscous differential.

The retractable headlamps of the NA (front car) were replaced by fixed headlamps on the NB (rear car).

There were a number of trim levels and special editions available, determined by local Mazda marketing departments. In the US, the base model was offered for US$13,995 at launch and was very basic, with manual windows, steel wheels, and without air conditioning or power steering. The "A Package" offered power steering, a leather-wrapped steering wheel, aluminum alloy wheels and cassette stereo. The "B Package" added power windows, along with cruise control and headrest speakers, while the "C Package" included a tan interior and top with leather seats. The "R Package" was for racing, and the annual special editions were formalized as "M Editions". These included all of the luxury options from the "C Package" as well as special paint and, sometimes, special wheels. In the UK, to celebrate Mazda's 24 hours of Le Mans win, Mazda brought out a special edition of the MX-5, with the winner's color scheme (see Mazda 787B) and came equipped with BBR (Brodie Brittain Racing) turbo conversion; the car is one of the most sought after special edition cars of the MX-5s.

The first generation MX-5 was phased out after the 1997 model year (with the exception of 400 limited edition Berkeley models sold only in the UK in 1998 to mark the end of the NA), with the final 1,500 NAs produced for the US market being the "STO" ("Special Touring Option") versions.

M2 special editions

[edit]

A small range of Eunos Roadster units were assembled by the M2 Corporation. Founded in November 1991, M2, also known as "Mazda Too", was Mazda's new off-line planning / niche-house / Research & Development company back in the early '90s. M2 employees had noble intentions — creating niche-mobiles derived from Mazda's volume products. Although M2's basic mission involved focusing on the "soft" aspects of vehicle design in an attempt to create more specifically targeted niche variants, the changes to the off-line cars would go well beyond mere cosmetics.

Heading the M2 operation was Mr. Masakatsu Kato, original father of the Miata (Eunos Roadster) in Japan, as well as creator of several Mazda concept vehicles. Kato-san was assisted by Hirotaka Tachibana, development engineer responsible for the superb dynamics of the Mazda FC (second generation RX-7) and the NA Roadster. M2 was based out of Tokyo, Japan. M2 was a 100% owned subsidiary of Mazda, and it was closed by Mazda in 1995. Mazda kept a similar program going with the Mazdaspeed vehicles, and then in the late '90s Mazdaspeed was absorbed into Mazda as a subsidiary company in Mazda Auto Tokyo. There were many types of M2 branded vehicles between 1991 and 1995, beginning with the 1001 up to the 1031 Cafe Racer (Dec-91).

M2-1001 Cafe Roadster (Limited 1/300)

M2 released the M2-1001 Roadster in December 1991. It was a special "Limited Production" Roadster variant that was a short production run of only 300 units, in a special Blue/Black Mica Paint, with a sticker price of $26,000. Prospective buyers were required to show up in person at M2's Tokyo headquarters to register for a lottery to place an order for this extremely limited Roadster.

This upscale Roadster was M2's first turn-key, race-ready offering. A list of popular features, while not exhaustive, is as follows: functional front airdam with integrated fog lamps, vintage aero mirrors, 4-point roll bar, vintage gauge cluster, fixed back bucket seats, polished 3-spoke steering wheel, stiffer suspension package with M2 specific rates, polished aluminum strut brace, upgraded exhaust by HKS, intake system, 1.6 L motor with new aggressive pistons, upgraded camshaft, lightweight flywheel, LSD cooling intake, manual steering, manual windows (A/C was optional), racing pedals, centerless console with matching shortened radio bezel, aluminum gas filler cap, a more aggressive wheel & tire package (15- x 6-inch Panasport rims), and a rear spoiler (which became standard for the R package). The performance changes made to the Roadster would bump the power to 98 kW (131 bhp) at 7,000 rpm, and 148 N⋅m (109 lbf⋅ft) of torque at 5,500 rpm. Once released, it proved so popular that people were paying up to $35,000 for one.

M2-1002 Vintage Roadster (Limited 1/300)

M2 released its second Roadster in November 1992, with a slightly different front bumper but all the same items as the previous 1001 Roadster. This one did not do as well as the 1001.

M2-1028 Street Competition Roadster (Limited 1/300)

M2 released its third Roadster in February 1994, based on the original "Jinba Ittai" concept made by Toshihiko Hirai. This was billed as a track-ready Roadster. (The US saw a cheaper version known as the R-Package.) Offered in Chaste White or Brilliant Black only, this Roadster used the new 1.8 L powerplant with upgraded pistons, camshafts, and other similar goodies as the previous 1001 and 1002. This Roadster had an output of close to 110 kW (150 bhp), and included 14-inch Eunos Factory Rims with a unique gunmetal paint with polished lip. The only real changes were a new set of lightweight side mirrors, MOMO Steering Wheel, centerless console, racing seats, racing tow hook, a set of lower lip spoilers (R-Package), and a newly designed "Duck-Tail" trunk lid with integrated spoiler. The M2-1028 trunk lid was made from aluminum and weighed only 3.5 kg (7.7 lb), a very light weight from the original lid of 7.0 kg (15.4 lb). It also came with a 6-point roll cage, but no soft-top, instead featuring a tarp that stretched over the cage. With optional FRP Hardtop with plexiglass rear window for more weight savings coming in at only 8.6 kg (19 lb).

Turbo conversions

[edit]

Brodie Brittain Racing (BBR) of Brackley, England, have had a long history of involvement with NA models in the UK, having supplied parts and equipment for a dealer supplied BBR Turbo version of the car between 1990 and 1991. This raised power output to 110 kW (150 bhp), and produced 209 N⋅m (154 ft⋅lb) of torque. The kit consisted of 68 parts and was covered by a full dealer warranty. They were supplied and fitted to around 750 UK spec cars, including for the 1991 'Le Mans' special edition, with a further 150 kits being supplied overseas.[19] Two decades later in 2011, BBR now offer a turn-key refurbishment package for old NA MX-5's, again including a turbo charger kit. This now increases power output to 160 kW (210 bhp), and produces 237 N⋅m (175 ft⋅lb) of torque. The estimated top speed is now 230 km/h (140 mph), with 0–97 (60 mph) approached in 5.5 seconds. The turbo charger used is a Garrett AiResearch GT25 ball bearing unit, and the package also includes an air-to-air intercooler, and a digital piggy-back ECU to control timing, fueling, and boost pressures. Subject to a satisfactory donor car, the refurbishment and turbo upgrade package includes rust treatment, a paint respray, new seats, wheels, and other trim. As of January 2011 the cost for a 'refreshed' BBR MX-5 Turbo is £7,500.[20]

In the United States, NA (and later model) turbo conversions are available from companies like Flyin' Miata. The conversions use mainly Garrett turbochargers (GT2560R) and are available as a kit or fully installed. Flyin' Miata also offers a CARB-legal kit as well.

Factory restoration program

[edit]
The MX-5 NA's unibody on display at the 2018 Osaka Auto Messe.

In 2018, Mazda began a factory restoration program for Eunos Roadster owners in Japan. The work is performed at the Hiroshima Factory where all Roadsters are built. The program offers a choice for each car to be fully restored to factory-spec using OEM parts, or selected restoration options. All work is then certified by TÜV Rheinland.[21][22] When the program was announced over 600 owners applied for the restoration program. At the Japanese language website, not all NA series can be restored and conditions are listed.[23]

On September 27, 2018, Mazda unveiled the first fully restored Roadster: a 1992 V-Special in British racing green with tan leather interior. The car belongs to tomato farmer Keiji Nishimoto, who has owned it since new.[24]

The Automotive Researchers' and Journalists' Conference of Japan gave the program a Special Award for Classic Car Restoration Service at the 2018 RJC Car of the Year Awards.[25]

On October 28, 2019, Mazda announced that they will introduce select reproduction parts for North American MX-5 Miata NA owners. All parts will be remanufactured using modern methods and materials while retaining the original look and feel of that era. Enkei will reproduce the original alloy wheels, but with a lighter weight and a more durable finish.[26]

Mazda MX-5 (NA)

View on Grokipedia
from Grokipedia
The (NA) is the first generation of the long-running line of two-seat sports cars, renowned for its lightweight design, rear-wheel-drive layout, and emphasis on engaging driving dynamics inspired by classic British roadsters of the and . Produced from 1989 to 1997, it debuted as a 1990 model year vehicle after premiering at the in February 1989 and going on sale in the United States in May of that year. Developed under Mazda's "Jinba Ittai" philosophy—meaning "horse and rider as one"—the NA aimed to revive the affordable, fun-to-drive roadster segment with a curb weight under 2,200 pounds (998 kg), a low center of gravity, and precise handling achieved through a front-midship engine placement and independent suspension. At launch, it was equipped exclusively with a 1.6-liter DOHC inline-four engine (B6-ZE) delivering 116 horsepower (86 kW) at 6,500 rpm and 100 pound-feet (136 Nm) of torque at 5,500 rpm, paired with a five-speed manual transmission as standard and an optional four-speed automatic. In 1993 for the 1994 model year, updated the NA with a larger 1.8-liter DOHC inline-four (BP-ZE) producing 128 horsepower (95 kW) at 6,500 rpm and 110 pound-feet (149 Nm) of torque at 5,000 rpm, with power increasing to 133 horsepower (99 kW) in 1996, along with minor chassis refinements including revised suspension geometry and optional on base models. Special editions like the limited-production models highlighted its pop-up headlights, manual soft top, and minimalist interior. The NA's instant success revitalized the roadster market, selling over 800,000 units globally across the MX-5 line in its early years and earning acclaim as the best-selling two-seat ever produced, with the first generation alone producing 431,506 units worldwide. It received multiple awards, including Motor Trend's Import Car of the Year, and its enduring popularity has led to a robust aftermarket and collector following, cementing its status as a benchmark for accessible performance.

Development

Origins and concept

In the aftermath of the 1970s oil crises, shifted its focus toward developing efficient and reliable vehicles to meet global demands for fuel economy and practicality, setting the stage for innovative projects that balanced performance with affordability. This context inspired the creation of the MX-5 (NA), a deliberate return to the joyful, open-top driving experience epitomized by British roadsters such as the and , which emphasized lightweight construction and rear-wheel-drive dynamics over raw power. The idea was initially proposed by American product planner Bob Hall in the early 1980s. The project, internally known as "Project R," was formally initiated in 1983 with the goal of producing a modern targeting 1,000 kg (2,200 pounds) and approximately 100 horsepower, prioritizing 50/50 , , and an engaging driving character to appeal to everyday enthusiasts. Led by chief designer and chief engineer Toshihiko Hirai, the initiative embodied Mazda's "" philosophy—translating to "horse and rider as one"—which sought to forge an intuitive, harmonious bond between the driver and vehicle, making the car feel like a natural extension of the body. Market research conducted by in the early highlighted a resurgence in interest for affordable s, particularly in the United States and , where the decline of British marques like MG and Triumph had created a void for reliable, low-cost roadsters that delivered pure driving fun without excessive complexity or cost. These surveys confirmed strong consumer demand for a vehicle that combined accessibility with the thrill of classic motoring, influencing Mazda to target a around $14,000 at launch to broaden its appeal beyond niche buyers.

Design and prototyping

The design philosophy of the Mazda MX-5 (NA) centered on achieving a perfect 50/50 to enhance handling balance, accomplished through a unibody construction and a front-mid layout that positioned the powerplant as far back as possible within the engine bay. This approach prioritized lightweight agility and driver engagement, drawing from Mazda's "" concept of oneness between rider and horse, while ensuring the vehicle remained affordable and reliable for everyday use. Prototyping efforts spanned from 1985 to 1989, during which several experimental vehicles and prototypes were constructed and rigorously tested across , the , and to refine handling characteristics under diverse conditions. Key innovations emerged from this phase, including a double-wishbone suspension at both axles for precise control and a rack-and-pinion steering setup that provided direct, responsive feedback to the driver. Styling emphasized classic proportions with a long hood and short deck to visually underscore the balanced layout, complemented by pop-up headlights that contributed to a low, sleek profile. Aerodynamic efficiency was validated through extensive testing, resulting in a of 0.38 that minimized lift and improved stability at speed. Engineers faced significant challenges in balancing with minimal weight, iterating through multiple full-scale clay models to optimize the without adding unnecessary mass. These efforts culminated in final approval in 1988, paving the way for production refinement.

Launch and production

Debut and market introduction

The Mazda MX-5 made its world debut at the Chicago Auto Show on February 10, 1989, presented as the 1990 model year vehicle. The compact roadster was unveiled under the MX-5 name internationally, while it was marketed as the Miata in the United States and as the Eunos Roadster in Japan. Sales commenced in the United States in May 1989, followed by Japan in September 1989 and Europe in 1990. Initial pricing in the US was set at $13,800, positioning the vehicle as an accessible entry into the sports car segment. Mazda marketed the MX-5 as a modern revival of the classic affordable roadster, emphasizing its lightweight design, rear-wheel-drive layout, and pop-up headlights for engaging driving dynamics. The "Miata" name derived from the Old High German word for "reward," reflecting the intended joy of ownership. The launch generated significant early buzz among automotive journalists, who praised its handling and value, contributing to rapid adoption. In the US, 23,052 units were sold during the partial launch year of 1989, rising to 35,944 in the full year of 1990; globally, sales exceeded 75,000 units in 1990 alone, surpassing initial projections.

Manufacturing and model years

The Mazda MX-5 (NA) was manufactured exclusively at Mazda's Plant No. 1 in , , with commencing in 1989.
