“Boy, it’s pretty loud in here.” That’s a quote from my better half, a woman who’s been driving a Nissan Murano for the past two years and loving every minute of the experience. Indeed, the Mazda CX-7 is loud inside. There’s equal parts engine grumble and turbo whistle, there’s wind noise on the highway, there’s road roar, and there’s impact harshness. The CX-7 doesn’t isolate occupants from the outside world. For conversation, bring one of those loudspeakers from that irritating Volkswagen commercial, or crank up the Bose Audiopilot sound system when traveling alone.
