I drove a $99,000 Infiniti QX80. It's a high-tech Japanese alternative to the Escalade

• The Infiniti QX80 is a full-size luxury SUV.
• I was impressed by its eye-catching looks, luxurious, high-tech cabin, and quiet ride.
• Unfortunately, the new twin-turbo V6 didn't deliver the expected performance boost.

The Cadillac Escalade has remained America's most popular full-size luxury SUV for more than a decade, but rivals like the Jeep Wagoneer, Lincoln Navigator, Lexus LX600h, and the all-new Infiniti QX80 are vying for attention.
