Model Description

The MX-5 ND retains the key features of previous generations: lightweight (around 1000–1100 kg depending on the version), rear-wheel drive, and a perfect 50:50 weight distribution. The design is more modern but keeps the rounded shapes and compact dimensions.

The interior is minimalist and driver-focused. Depending on the trim, it may include:

  • 7-inch touchscreen (Mazda Connect).
  • Leather seat upholstery.
  • Bose audio system with headrest speakers (for the Roadster).

The suspension consists of independent double wishbones at the front and a multi-link setup at the rear. The transmission is a 6-speed manual or automatic (in some markets).

 

Interesting Facts

  • The lightest MX-5 since the 1990s — the 1.5L version weighs just 1009 kg, making it one of the lightest modern cars.
  • Inspired by the Lotus Elan — the ND’s design was partly influenced by the classic British roadster.
  • Guinness World Record — the MX-5 is the best-selling two-seater sports car in history (over 1 million units sold since 1989).
  • Special editions — including the 30th Anniversary Edition (2019) in orange and the 990S (Japan) with a lightweight construction.
  • Power evolution — the 2.0L engine received a power boost from 155 to 181 HP in Europe in 2018.

 

The MX-5 MK4 stays true to the "Jinba Ittai" ("horse and rider as one") philosophy, offering pure driving enjoyment without excess. It remains one of the last affordable sports cars with analog driving dynamics and minimal electronic intervention.
