Mazda MX-5 Miata NB MX-5 Miata NB VS Toyota GR86 GR86

The Mazda MX-5 Miata NB and Toyota GR86 occupy a rare space in the enthusiast world: both are rear-drive, naturally aspirated, and laser-focused on delivering accessible, repeatable fun. Yet, the way they pursue speed—and the type of driver each rewards—could hardly be more different. The Miata NB is a study in mechanical simplicity and tactile feedback; the GR86 is the evolution of that ethos, faster, more mature, and more forgiving, but not without its own trade-offs.

On the stopwatch, the GR86 consistently puts daylight between itself and the NB at most tracks, especially when both run comparable modifications and 200-treadwear tires. Consider Nürburgring - BTG, where a medium-mod GR86 on Dunlop Direzza H1s clocks 7:41, a full 55 seconds ahead of a medium-mod NB on Yokohama AD08Rs (). This isn’t just about power—the GR86’s 228 PS and 249 Nm of torque versus the NB’s 140 PS/133 Nm—but about how the Toyota deploys its grunt. Where the Miata’s 1.8L BP-4W needs to be wrung out and managed with precise throttle, the GR86’s 2.4L flat-four delivers a flat, useable torque curve that fires the car out of corners with ease. The result is a car that feels light on its feet despite its extra 500 lbs, especially with the right suspension and tire setup.

But numbers only tell part of the story. The Miata NB’s genius is in its communication. The steering rack is pure, uncorrupted by weight or electronics; the double-wishbone suspension translates every nuance of the tarmac. At tracks where rhythm and rotation matter more than outright power, the NB can still surprise—especially in heavily tuned form. At Buttonwillow 13CW, a 400 PS, aero-laden NB on Hoosier A7s laps in 1:44.841, over 12 seconds faster than a medium GR86 on 200tw rubber (1:56.9). Granted, this is an extreme case, but it illustrates the NB’s adaptability—decades of motorsport have created a tuning ecosystem that can transform the car from momentum tool to outright monster, should you wish to chase tenths through engineering rather than displacement.

Driver experience is where the philosophies diverge most. The Miata is a car that rewards patience and precision. It’s happiest when being hustled with delicate hands—late trail braking, careful weight transfer, and exploiting its willingness to rotate mid-corner. A skilled driver can exploit every inch of curb and every ounce of grip, especially on technical layouts. The GR86, by contrast, is more forgiving at the limit. Its wider track, stiffer chassis, and modern suspension geometry allow it to absorb mistakes without snapping back. At Buttonwillow 1CCW, for example, a medium-mod GR86 on GT Radials laps 2:10.735, over 15 seconds ahead of a light NB (2:26). The Toyota’s pace is accessible to a wider range of drivers—a car that flatters the moderately skilled, yet still holds rewards for the committed.

Yet, there remain circuits where the NB, particularly with radical modification, can turn the tables. At Misano, a K20A2-swapped NB on Hankook TDs runs 1:54.4, dispatching a lightly modified GR86 by over 11 seconds (2:05.6). Here, the NB’s lighter weight and aggressive power-to-weight ratio exploit every technical sector and braking zone, especially in the hands of a driver who understands how to keep the car on the edge of adhesion.

In sum, the GR86 is the more capable all-rounder in modern trim: faster on most tracks, more approachable at the limit, and with a tuning scene that’s rapidly catching up to the Miata. It’s the car that will let you chase lap times all day, with fewer surprises and less fatigue. The NB Miata is for the purist—the driver who wants undiluted feedback, who relishes the process of extracting every last tenth from a chassis that tells you everything, and who understands that sometimes, the most rewarding cars aren’t always the fastest on paper.
