As much as I love V8's and cubic centimeters, I've got say I see it hard to compete with AWD / IWD vehicles of the future.
I suspect some of these IWDs could pin you to the seat even if they were departing on a teflon runway!
But for heart-breaking love, nothing beats a 2" single system bolted onto 5.0L of unbreakable cast iron. My family could detect me coming home from the vibrations in the floor long before they could hear anything.
Back in the day I referred to my babies as mobile whale communications systems, and I didn't need some tosser sub-woofer! The unfortunate part of all that, you could watch the fuel gauge falling as fast as the scenery went by!
