2021 Mazda 6 Signature 2.5T – Re-Driven – Final Drive in Unity With Soulful Sedan

2021 Mazda 6 Signature 2.5T: A genuine rider in unison with steed premium volume family sedan will be taking a hiatus after this year.

THE FAMILY SEDAN WITH SOUL:  In the quest for a near luxury family sedan, honed with driving enthusiasm in mind, and priced for those demonstrating good fiscal sense, there is but the Mazda 6 or as some say Mazda6. In fact many have observed that the introduction of the 2.5L turbocharged Signature trim knocked on the door of entry Audis, BMW’s, and Benzes.

UNDER-APPRECIATED, HOPEFULLY TO RETURN: Literally within days after Roadblazing.com had an encore stab at a 2021 Mazda 6 Signature 2.5 Turbo, Mazda U.S.A. announced the current model year’s production would be it’s last for Americans. Clearly, even among takers of automotive “Jinba Ittai,” the culprit is the current overwhelming preference for unity with crossover steeds such as the brand’s popular CX-9, CX-5 and CX-30. Stirred with driving passion by the emotional Soul Red hue of the supplied test 2021 Mazda 6 Signature, musings persist that this machine “Deserves to Be Back” (in the guise of an anticipated rear / all-wheel drive longitudinally powered version).
