The Acura ZDX is a mid-size luxury crossover SUV with a sloping rear roofline developed by Honda for its upmarket brand Acura. The car was originally planned to be called the 'MSX'. The ZDX debuted at the 2009 New York International Auto Show on April 8, 2009, as a 2010 model. The vehicle was also the first to be completely designed at Acura's southern California design studio in Torrance. The original ZDX concept was penned by Michelle Christensen who labeled it a '4-door luxury sports coupe' and which Acura says 'blurs the distinction between coupe, sedan and sport utility vehicle.' The ZDX features Acura's first six speed automatic transmission, advanced ventilated seats, as well as other luxury appointments. Although the ZDX shares a similar profile with the Honda Crosstour, the two vehicles are not mechanically related: the latter is based on the Honda Accord, while the ZDX is based on the Honda Pilot/Acura MDX.
