2018 Mazda6 SKYACTIV-G Engine Explained

Mazda's award-winning, SKYACTIV-G 2.5T gasoline turbo engine returns for its second application. The SKYACTIV-G 2.5T is an engine renowned for its nearly instantaneous, ample torque, courtesy of its Dynamic Pressure Turbo, which accelerates exhaust gasses through a tiny inlet to quickly spool up its turbocharger at low RPM before opening a larger secondary passage to use throughout the engine's operational range. The engine produces torque on par with a 4.0-liter V-8 engine. Mazda6 was already a class favorite among discerning drivers. These latest upgrades will launch Mazda6 above the mainstream sedan fray, changing the idea of what an affordable midsize sedan can and should be.

In this latest round of thoughtful improvements, engineers have revisited every aspect of Mazda6's chassis, with its suspension offering a smoother, more linear ride quality and greater NVH refinement similar to the ultra-quiet CX-9. Its steering rack is now rigid-mounted to the chassis, offering greater steering response and feel, and its SKYACTIV-CHASSIS has been stiffened in complement with the revised suspension to offer both a smoother ride and to improve outright dynamic performance.

Enabling this more comfortable ride without compromising the Mazda6's handling, the suspension geometry has been revised, with roll-steer changes that promote more neutral handling.

Additionally, body reinforcements, thicker sheet metal in the rear wheel-wells, reinforced chassis bracing and even thicker suspension trailing link mounts help improve interior conversation sound quality, putting Mazda6 into rarified air when it comes to quietness, refinement and capabilities.

Old video but came to say that my 2018 cx5 is in the shop because one of the adjustable Hydraulic lifters failed and is causing loud ticking. I had a compressiom test done and cylinder 4(which has the failed lifter) showed 60 psi HIGHER pressure than the other cylinders. Seems to all be related to that lifter. Only reason for the adjustable lifters is for the cylinder deactivation which just puts more wear and tear on the engine. And for what? Less than 1 mpg better fuel economy? Not worth it if the engine suffers premature damage. The most environmentally friendly car is the one you buy once and never have to replace and keeps running

how to deactivate this cylinder deactivation, I prefer the effort to be spread evenly over 4 cylinders than only 2 especially on long I own one 2.0 G

should have a V6 turbo instead. I have a 2018 CX-9 but it's a wee bit gutless

[AudiophileTubes]

BUT is it a RELIABLE long term engine that will last with no problems?

[Иван-оъь]

2.5T don't have a cylinder deactivation feature

Looks like they copied Honda on that tumble flow on the head

Worst engine for dirty valves from crank case ventilation and chemicals don’t work
