While not due in dealers until this winter, Acura has released the first official photos as well as a handful of key details about its upcoming ZDX -- a variation on the contemporary crossover theme which the automaker is calling a "four-door sports coupe." Although the head- and tail light treatments have been revised and the front fascia treatment tweaked a bit, the production ZDX retains all the primary styling cues seen in the concept version that was presented at this year's New York International Auto Show. The five-passenger ZDX will share the same 3.7-liter SOHC V6 engine as the Acura RL and TL models and send 300 horsepower and 270 lb.-ft. of torque to a new six-speed, paddle-shifted automatic transmission and on to each wheel via Acura's torque-vectoring Super Handling All-wheel Drive (SH-AWD) system. Acura will offer this dynamic newcomer in three trim levels. Even the "base" ZDX will be impressively equipped and include items like hand-stitched leather upholstery, a panoramic glass roof with moveable sunshades, HandsFreeLink Bluetooth connectivity, a power tailgate and a premium audio packed with CD player, AM/FM/XM radio and USB/AUX interfaces with iPod integration. The ZDX with Technology Package adds upgrades like a voice-recognition navigation system and an Acura/ELS Surround premium audio system with multi-view rear camera, while opting for the top-line ZDX with Advance Package also nets a blind-spot information system, a Collision Mitigating Braking System (CMBS) and Adaptive Cruise Control (ACC). Acura offered no word on pricing.
