The Mazda MX-5 Miata NC and the Subaru BRZ tS represent two celebrated Japanese rear-wheel-drive sports cars, each with a dedicated following and a distinct approach to delivering driving enjoyment. Both cars share a manual gearbox and a focus on balanced handling, yet their performance characteristics and track results reveal nuanced differences that highlight their unique engineering philosophies. 

The Mazda MX-5 Miata NC, powered by a naturally aspirated 2.0-liter inline-four producing 172 horsepower and 187 lb-ft of torque, emphasizes lightweight agility and driver engagement. Weighing just 2,546 pounds, it boasts a nimble chassis and a top speed of 131 mph. Its 0-60 mph time of 6.4 seconds matches that of the BRZ, underscoring its sprightly nature despite having less outright power. Mazda’s commitment to lightweight design and precise handling shines through in its lap times, particularly on tighter, more technical circuits. 

On the other hand, the Subaru BRZ tS features a 2.0-liter naturally aspirated boxer engine delivering 205 horsepower and 212 lb-ft of torque. It is heavier at 2,798 pounds but compensates with increased power and a slightly higher top speed of 143 mph. The BRZ’s longer wheelbase and wider track contribute to enhanced stability, especially at higher speeds. Its performance on the track reflects this balance, showing strength on flowing circuits where power and stability are paramount. 

Comparing their fastest laps across various tracks reveals interesting contrasts. At Eagles Canyon Raceway, the BRZ edges out the Miata with a lap time of 2:14.780 versus 2:15.560, demonstrating its advantage in power and stability on a moderately fast, technical course. Conversely, at NCM Motorsports Park, the Miata posts a quicker lap of 2:25.777 compared to the BRZ’s 2:26.720, suggesting the Miata’s lighter weight and sharper handling can trump raw power on more technical layouts. 

Sonoma Raceway further illustrates the BRZ’s strengths, with a best lap of 1:54.050 against the Miata’s 1:55.593, highlighting the Subaru’s ability to carry more speed through flowing corners. However, on shorter, twistier tracks like Thompson Speedway, the Miata’s lighter weight and agility shine through with a 1:19.900 lap, faster than the BRZ’s 1:23.418, reaffirming its prowess in tight, technical environments. 

Modifications and tire choices also influence their comparative performance. The Miata’s lighter chassis benefits significantly from medium to heavy modifications, often improving lap times by enhancing grip and suspension response. The BRZ, while already well-balanced, gains from tire upgrades and suspension tuning that exploit its power and chassis stability, especially on faster circuits. 

In summary, the Mazda MX-5 Miata NC and Subaru BRZ tS cater to slightly different driving preferences. The Miata excels in lightweight agility and precision, making it a formidable competitor on tight, technical tracks where nimbleness is key. The BRZ offers more power and stability, favoring circuits that reward higher speeds and flowing corners. Both cars deliver engaging rear-wheel-drive experiences, but their distinct strengths mean that driver choice will often hinge on the type of driving and track conditions they prioritize.
