"Externally, the 2011 RDX has an aggressive, sporty appearance thanks to bold front and rear fascias, Acura’s signature grille, pronounced wheel arches, 18-inch 10-spoke aluminum wheels and upscale trim accents. On the inside, the RDX makes use of a rich blend of leather, artful stitchwork and flowing curves— paired with lots of cutting edge technology.
True to Acura’s leadership in the application of advanced technology, the RDX incorporates a class-leading array of features that keep passengers informed, entertained and in control. Every RDX features as standard Bluetooth® HandsFreeLink® connectivity with Bluetooth® audio capabilities, a 7-speaker Acura Premium Sound System and a USB port that allows the connection (and charging) of items such as an iPhone® or iPod®. For those who want to be even more connected to the world around them, an available Technology Package includes the Acura Navigation System with Voice Recognition™, AcuraLink Real-Time Traffic with Traffic Rerouting™, and AcuraLink Real-Time Weather™ with radar image maps.
Based on Acura’s “Safety Through Innovation” initiative, the RDX incorporates leading safety technologies including Acura’s renowned Advanced Compatibility Engineering™ (ACE™) body structure, a wide array of airbags (including front, side and side curtain airbags), Vehicle Stability Assist ™ (VSA™), ABS with Brake Assist, and front seats with active head restraints.
Powertrain
The RDX is equipped with a turbocharged 2.3-liter DOHC 16-valve inline four-cylinder engine incorporating computer-controlled “intelligent” i-VTEC® for the intake valves that delivers enhanced performance across a broad powerband. The heart of the RDX’s performance is its Variable Flow Turbocharger (VFT) that delivers an unusually broad powerband with virtually no lag in response. The turbocharger works in concert with i-VTEC® to deliver outstanding acceleration and efficiency while driving at a variety of speeds.
Rated output for the 2.3L I-4 engine is 240 horsepower at 6,000 rpm with 260 lb-ft of torque at 4,500 rpm. The RDX has an EPA city/highway/combined fuel economy rating* of 19/24/21 mpg (RDX 2WD) and 17/22/19 mpg (RDX SH-AWD™) along with meeting EPA TIER 2 – BIN 5 and CARB LEV-2 ULEV emissions standards. Due in part to the decreased weight of the two-wheel-drive model, the RDX gets improved fuel economy versus the SH-AWD® model— resulting in an improvement of 2 mpg in both city and highway fuel economy."
