Acura’s redesigned 2007 MDX (concept version is shown, and is about 90-percent correct for production) is a seven-passenger sport/utility vehicle, but this time around the emphasis is on the sport portion of that equation. In addition to a stronger V6 engine and as much safety technology as engineers could pack into it, the 2007 Acura MDX features accoutrements such as a premium surround sound system with XM satellite radio; a wireless communications system that works with Bluetooth-enabled cell phones; a navigation system with real-time traffic reporting; and a collision mitigation braking system that detects an impending accident, taking action to reduce speed and prepare the safety systems before impact.
