"Despite the extra oomph, the 'slow car fast' mantra still fits the more powerful Miata. That's a good thing. The freshened engine still feels natural. Power delivery is smooth and linear, with the increased redline welcome to folks who like to rip around tight canyon roads. The 7,500 rpm cutoff also means that you don't need to shift to third during 0-60 runs.
The additional refinements to the Miata's powertrain only add to the experience. The dual-mass flywheel makes shifting a manual-equipped Miata even smoother than before. And the new exhaust has a deeper tone, but it's still quiet and subtle. These simple revisions alone would be notable, but the package's absolute cohesion make the updated Miata holistically splendid.
Whenever a car gets a substantial amount more power without similarly revising the suspension, there's always a risk of imbalance: an engine that overwhelms the chassis. The Miata doesn't fall into that camp. You can absolutely feel the extra power, even lower in the rev range, but the engine only complements the Miata's key characteristics."
