The 2019 Miata Has 181 HP, a 7500 RPM Redline, and a Telescoping Steering Wheel
"First modification to support the engine spinning so much higher is an increase in the rate of the valve springs to provide more tension. The pistons have also been lightened by 27 grams by shaving down the dome and getting the valve reliefs as close to the edges of the piston skirts as possible.
The connecting rods get a similar treatment, losing 41 grams of weight due to a more compact shape along with bolts that are shorter and thinner. The crankshaft gets some optimization in the form of how the counterweights are arranged. The changes continue on with the throttle body which sees its opening increased by 28 percent in order to provide more air to the engine. The airflow changes continue down towards the valve with improvement in tumble flow and an increased valve diameter.
The updates in the pistons allow for the increase of air and fuel to be safely combusted as the new design is optimized to prevent knock while maximizing thermal efficiency and minimizing emissions. The combusted mixture exits the engine through a new larger exhaust valve and a new exhaust manifold with larger runners.
All of this newfound power is transferred to the transmission through a new low-inertia dual mass flywheel which is intended to absorb noise and vibrations so that they don’t transfer to the cabin. The performance changes are rounded out with a new muffler which has been updated to reduce high frequency noise and work better with the increased redline.
Hashimoto Yohei of Car Watch states the changes in the exhaust are apparent as soon as the car is started describes the pull to 7500 RPM as exhilarating. He also states that the new redline allows the car to be wound out a bit more. That prevents upshifts that would have been required in the past and the Miata gets up to speed more quickly.
The rest of the changes involve some new interior and exterior colors (as well as the absence of the ugly LED running lights) along with the addition of safety equipment which expands features like Smart City Brake Support to the roadster. The last category which they cover is a telescoping steering wheel, a first for any Miata. This will surely be an exciting development for those of us that are on the taller side. The author states that he was able to comfortably slide down further in the seat since the wheel can telescope in by 30 millimeters now."

Better to get the Ford Ranger Raptor ... It's diesel ... Seats more people ... Can go places where the Mazda MX-5 can't ... More practical as daily driver ... Wife can't complain that it's impractical ...
