General Motors (GM -0.04%) unveiled its completely redesigned Cadillac Escalade at an upscale party in New York this week. Our Motor Money team of John Rosevear and Rex Moore was there, and came away impressed with the luxury SUV.

In this video, John and Rex chat with chief engineer Jeff Luke about the three ways the 6.2-liter engine saves fuel. EPA estimates are not yet available, but the new Escalade should be more efficient than its predecessors.
