2019 Mazda MX-5 Power Bump Details Come into Focus
Back in March, I talked about a rumor going around that the 2019 Mazda MX-5 would be getting a healthy power bump to keep fans happy. What we heard was that the 2.0L Skyactiv-G engine would be going from 155 hp to 181 hp. New details about how that power will be added have turned up in what is purportedly a leaked document from Mazda Canada.
The document shows that the new engine will use altered camshaft lift and valve size, a freer flowing exhaust, and smooth out and enlarge the piping for the air intake. The engine will also get revised internals with lighter pistons with lower crowns, lighter connecting rods, and a crankshaft balanced for higher RPMs.
Mazda is also tipped to be going with a low-inertia dual-mass flywheel. All that means more power without having to resort to turbos. 181 hp in an MX-5 that weighs in at 2,332 pounds sounds like fun.
