The Acura RDX is Acura's first compact luxury crossover SUV, taking over from the MDX as Acura's entry-level crossover SUV, as the MDX grew in size and price.

First generation (TB1, 2007-2012)
Originally previewed as the Acura RD-X concept car, the production RDX had its debut at the 2006 New York Auto Show and went on sale on August 11, 2006. A facelifted 2010 model went on sale in August 2009, adopting Acura's power plenum grille seen on its sedan models. Front-wheel drive was also added.
Engine
The first generation RDX is powered by turbocharged gasoline engines; at the time, this was uncommon among Honda vehicles although it has since become common. The 2.3-litre straight-4 K23A1 engine has all-aluminum construction, an i-VTEC head, and dual balance shafts. It is also one of the only four-cylinder powered luxury SUVs. Honda's variable flow turbocharger reduces turbo lag by using a valve to narrow the exhaust passage at low rpm, increasing the velocity of the exhaust flow and keeping the turbine spinning rapidly. At higher rpm, the valve opens to allow more exhaust flow for increased boost. The engine also features a top-mounted intercooler which receives air from the grille, channeled by ducting under the hood. The Acura RDX engine is rated at 240 bhp (179.0 kW; 243.3 PS) at 6000 rpm with a torque peak of 260 ft·lbf (350 N·m) at 4500 rpm. The U.S. Environmental Protection Agency (EPA) estimated fuel mileage is 19 mpg-US (12 L/100 km; 23 mpg-imp) city and 23 mpg-US (10 L/100 km; 28 mpg-imp) highway miles per gallon. Driving style and the terrain plays an important part in this Vehicle's fuel economy. Uphill driving, frequent lane changes and sudden accelerations can increase turbo usage to increase torque output to the SH-AWD system and thus cause much higher fuel consumption. New more recent EPA mileage estimates as of February 2007 are 17 mpg-US (14 L/100 km; 20 mpg-imp) city and 22 mpg-US (11 L/100 km; 26 mpg-imp) highway. The required fuel is premium 91 octane unleaded.
Drivetrain
The Acura RDX comes standard with a five-speed automatic transmission with Acura's SportShift sequential manual shift capability, activated by paddles mounted on the steering wheel. The paddles can be used in Drive (D) to make a gear change with the transmission returning to automatic mode as soon as the vehicle resumes a steady-cruise state. The Sport (S) setting has higher shift points and quicker downshifts, and using a paddle in "Sport" immediately puts the transmission in full manual mode. The RDX also has a version of Acura's Super Handling All-Wheel Drive (SH-AWD), first seen on the flagship RL sedan. The system can vary the front/rear torque distribution from 90/10 to 30/70, depending on whether the vehicle is accelerating, cruising, hill climbing, taking a curve, or encountering poor road conditions. When taking a curve, a pair of magnetic flux clutches in the rear differential can transfer as much as 100% of the available rear torque to the outside wheel. That torque transfer, combined with a 1.7% rear over-rotation of the rear wheel helps rotate the RDX through a turn.
Interior
The RDX seats five and comes standard with leather seating, a moonroof, automatic climate control, and all the expected power features. The RDX 7-speaker audio system features an in-dash 6-CD changer, which is capable of playing standard Audio CDs, and Data-CDs burned with either MP3 or WMA files, it also plays DVD-A type CDs. The RDX's sound system also includes XM Satellite Radio with a complimentary 3-month subscription.
Much of the interior technology introduced in the RL sedan is found in the optional "Technology Package". This package includes the latest version of Acura's navigation system, complete with a rear view camera, XM Nav-Traffic real-time traffic monitoring, and Zagat restaurant reviews. The package also features a 10-speaker ELS Surround audio system with DTS and Dolby Pro Logic II surround sound. The audio system plays DVD-Audio discs as well. Both stereos come with a 1/8" (a 3.5mm) auxiliary input jack, which may be used to plug in external sources such as iPods. For 2007, Acura also offered an iPod adapter for the RDX, which was wired into the glove box, and allowed the iPod to be controlled through the RDX's sound system interface. Due to hardware incompatibilities the Honda/Acura iPod musiclink has been discontinued as of model year 2008. 2010+ models come standard with a USB connection that interfaces with Apple iPod players and other USB mass storage devices, such as flash drives that contain MP3, WMA6 or AAC music files while being stored in the center console.
Almost all of the ELS sound system's operations can be activated by voice command, as can most of the operations for the navigation and climate control systems. In addition, the vehicle will interact with most Bluetooth-equipped cell phones. The driver can initiate or receive calls through verbal command. During the call, the sound system will mute and channel the call through the speakers while caller and signal information is displayed on the instrument cluster.
The tailgate opens over six-feet high and 60/40 rear seatbacks fold down for a flat cargo area. A hard cargo cover can fit flush on the floor when not needed and is reversible to carry wet or dirty cargo. The cabin includes several storage areas including a lockable center console that can hold a standard size laptop computer. The cargo hold is small size compared to most rivals and does not have the adjustable cargo tracks or a rear parcel shelf.
Safety
The Acura RDX is the second Acura vehicle to feature the Advanced Compatibility Engineering (ACE) body structure which is designed to absorb energy from a collision. The RDX comes standard with six airbags, including dual front airbags, front side airbags and dual side curtain airbags. The front airbags use a dual-threshold, dual-stage technology that can adjust the timing and speed of each airbag deployment depending on the degree of impact and the driver's or front passenger's seat belt usage. If sensors deem the front passenger too small (less than 65 lb (29 kg)), the front airbag is designed not to deploy. The front passenger's side airbag is also designed to shut off if a child or small-statured adult is leaning into the airbag's deployment path. In the event of a sufficient side impact or roll-over, the side curtain airbag deploys from above the door frames of the affected side, with coverage for both the front and rear occupants on that side, and stays inflated longer than if there were a collision.
Front seats have active head restraints and their seat belts are equipped with pre-tensioners and force-limiters. As of November 2006 the RDX was crash tested by the U.S. National Highway Traffic Safety Administration, resulting in a perfect "5 Star" rating for driver and passenger frontal crashes, and front and rear side impacts, along with "4 Stars" for rollover.
The Insurance Institute for Highway Safety, Highway Loss Data Institute (IIHS-HLDI) gave the 2007-12 RDX the grade of Good "G" for moderate overlap front test and side impact test. The grade of Marginal "M" was given for roof strength evaluation.

Second generation (2013-present)
The second generation RDX was revealed during January 2012 at the North American International Auto Show going on sale in April. The turbocharged four-cylinder engine was replaced by a 3.5-liter V6 mated to a six-speed automatic, improving gas mileage to an EPA estimated 20/28/23 mpg (city/highway/combined) by using variable displacement (VCM). The SH-AWD system will be replaced with a simpler and less costly AWD setup.
A 5-inch display, tri-angle rear-view backup camera are standard, as well as keyless entry with push button start. Also, standard Bluetooth hands-free calling and Pandora music can be streamed wirelessly into the audio system. When upgrading to the Technology package, a power tailgate is included, along with an upgraded 60-gigabyte hard disc (HDD) based navigation system with 8-inch screen, this system enables 15GB of music to be stored.
In China, the RDX is offered with two engines. A 3.0-liter SOHC V6 produces 263 hp at 6700 rpm and 220 lb.ft of torque at 4600 rpm, while the 3.5-liter SOHC V6 produces 273 hp at 6500 rpm and 254 lb.ft at 4400 rpm. Both engine choices come with either FWD or AWD.
2016 Facelift
The refreshed 2016 RDX was introduced at the 2015 Chicago Auto Show, sales began in mid-April. The updated RDX uses a slightly more powerful revised 3.5L SOHC V6 that produces 279 horsepower and 252 lb-ft of torque. The exterior adds LED headlamps (low and high beams, DRL pipe and amber turn signals) and LED taillamps. Additionally, the 2016 RDX includes several driver assists in the AcuraWatch package including Adaptive Cruise Control and Lane Keeping Assist System (LKAS). AWD was also updated to send up to 40% torque to rear wheels opposed to up to 25% in the previous model.
