Mazda MX-5 (NA)

[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.

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.

[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.

[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.

Power brakes, steering, stereo, and air conditioning were added as standard equipment in later years, and depending on market.

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.

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.

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.

250 examples sold from March '91, produced in British Racing Green with tan interior, to celebrate the 1st anniversary of the MX-5 in the UK.

These have a numbered brass plaque on the passenger-side padded dashboard and on the front of the Owners Book, and are fitted with colour-matched 15" OZ alloy wheels from MSW (Mazda Sports Workshop) which are often mistaken for BBS, but which are unique to this model.

[14] Limited to 3,997 units in the United States / 1,051 in Canada, this edition of the MX-5 NA was offered only in British racing green with tan leather interior and tonneau cover and featured a wooden Nardi shift knob and handbrake lever, stainless steel door sills, air conditioning, CD player, cruise control, and headrest speakers.

[15] Limited to 1,505 units in the USA / 300 in Canada, this Limited Edition model was equipped similarly to the 1992 Black Miata, but with red leather interior, sport suspension, front and rear spoilers, rear skirt, air conditioning, headrest speakers and 14-inch BBS wheels.

[15] Advertised by Mazda USA as "Still The One" and limited to 1,500 units, the Special Touring Option (STO) was offered in Twilight Blue Mica and featured the exterior options of the 1996 M-Edition, but lacked the Torsen differential, cruise control, premium stereo, and hardtop (which elicited the other nickname of "Stuff Taken Off").

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.

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.

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).

M2 released its third Roadster in February 1994, based on the original "Jinba Ittai" concept made by Toshihiko Hirai.

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 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.

[21] On September 27, 2018, Mazda unveiled the first fully restored Roadster: a 1992 V-Special in British racing green with tan leather interior.

[23] On October 28, 2019, Mazda announced that they will introduce select reproduction parts for North American MX-5 Miata NA owners.
