The Mazdaspeed AZ-1: The Kei Supercar Collectors Call the Holy Grail

Mazda’s Mazdaspeed AZ-1 is a mid-engined, gullwing-door Kei supercar that has quietly become one of the most sought-after Japanese imports in the U.S.

This 1993 Autozam-badged gem, built for just two model years, delivers a modest 64 HP from its 657 cc naturally aspirated three-cylinder engine, yet its featherweight 1,587-lb curb weight turns it into a pocket rocket.

Power flows to the rear wheels through a five-speed manual transmission, and the car’s razor-sharp proportions—reminiscent of a Ford RS200 and Ferrari F40 in a blender—make it an instant head-turner.

Only about 4,400 AZ-1s were ever built, with roughly 150 of those receiving the Mazdaspeed treatment, including this one.

That makes it one of the rarest Kei cars ever, a status that’s only amplified by its near-mint condition: imported to the U.S. last year, it’s been driven just 2,200 miles since new.

The Mazdaspeed upgrades add serious attitude, including a menacing body kit with a new hood, front bumper, and fixed rear wing, plus front and rear strut bars, a limited-slip differential, and a stainless steel exhaust. The cabin stays mostly original, trimmed in red and black with a modern Kenwood stereo tucked in.

While the AZ-1’s 64 HP and 63 lb-ft of torque might not sound like much on paper, the car’s sub-1,600-lb weight ensures it’s a hoot to drive.

This particular example is listed on Bring a Trailer’s auction out of San Rafael, California, with bidding closing within the week.

Last year, a similar Mazdaspeed AZ-1 sold at a Japanese auction for 5,595,000 yen (approximately $34,600 at current exchange rates), a price tag that reflects its cult status among collectors.
