The Mazda CX-9 crossover SUV receives only minor updates for 2009. All '09 CX-9 trims now come equipped with a trip computer and Bluetooth phone compatibility as standard equipment. A Power Seat Package for the CX-9's entry-level Sport trim adds heated seats and heated outside mirrors, while the optional Moonroof and Bose Audio Package now includes Sirius satellite radio, as does the Rear Seat Entertainment System Package. Although the mid-level Touring trim remains unchanged for '09, the top-of-the-line Grand Touring trim receives an auto-dimming rear-view mirror with Homelink. Introduced in 2007 and now in its third year of production, the CX-9 crossover SUV features sport-oriented styling, with a smooth front end, an angled windshield, a tapered roofline, and chrome-accented sides that sweep back into a sleek tail. A stiff unibody chassis ensures a solid ride and agile handling, while a five-star crash rating for front and side impacts from the National Highway Traffic Safety Administration ensures the safety of occupants. The CX-9 seats seven passengers in three rows. Large rear doors and an easy-sliding second row make it easy to access the rear row of seats, which comfortably accommodates adults. The sliding second row of seats also makes it easy to adjust legroom for rear-seat passengers. With all three rows occupied, the CX-9 provides more than 17 cubic feet of cargo space, but by folding down both rows of rear seats, drivers can open up more than 100 cubic feet. Standard features across the line include anti-pinch power windows, power door locks with two-stage unlocking, three-zone air conditioning, map lights, and cupholders for all three rows. The mid-level Touring trim adds such standard features as heated sideview mirrors and a number of optional features, including a powered rear hatch and a DVD navigation system. The high-end Grand Touring trim adds indirect interior lighting and a Smartcard advanced keyless entry system, among other features. All CX-9 trims come with Dynamic Stability Control and traction control, roll stability control, advanced dual front airbags, side air curtain airbags with rollover protection, antilock brakes with electronic braking distribution, and a crushable brake pedal, which prevents injury to the driver's foot in the event of an accident. Optional features across the line include a power glass sliding moonroof, a backup camera, roof rails, and a dockable entertainment system with a Game Boy Advance. A 273-hp, 3.7-liter V6 engine powers all CX-9 trims. The engine links to a six-speed Sport A/T automatic transmission, designed to provide optimal acceleration and passing performance as well as fuel efficiency. As in previous years, all three CX-9 trims are available with either front-wheel drive or with Mazda's Active Torque Split all-wheel-drive system.
