3.5-liter V-6 Engine
The powerful 3.5-liter i-VTEC® V-6 engine produces an impressive 273 horsepower and 251 lbs.-ft. of torque, while the refined Variable Cylinder Management (VCM II) system and low friction technology produce class-leading efficiency. The front-drive model delivers an efficient EPA Estimated
Fuel Economy of 20 / 28 / 23 city/highway/combined, while the AWD model does nearly as well with 19 / 27 / 22 highway.
enables cylinders to be shut off at cruising speeds in
order to increase highway mileage. Fuel efficiency is
enhanced by lower-friction piston rings, the ability to run on lower viscosity oil and transmission fluid, and other friction-reducing features.
i-VTEC®, which stands for Variable
valve Timing and Electronic lift Control, enables the intake valves to open
deeper and longer when the engine reaches approximately 4500 rpm to enhance
airflow and allow the RDX to continue to build horsepower at levels where other
engines may run out of
Variable Cylinder Management automatically changes the V-6 engine to run on six, four or three cylinders depending on driving conditions resulting in significantly improved highway mileage.
Sequential SportShift Automatic with Paddle
The 6-speed Sequential SportShift automatic with paddle shifters gives you the best of both worlds by providing the convenience of precise and intuitive automatic shifting as well as shift-for-yourself control. Set the transmission to "Drive" for smooth gear changes with an emphasis on fuel economy. Select "Sport" for quicker acceleration, as the transmission allows the engine to rev higher before upshifting. Using a paddle shifter in "Sport" puts the transmission into full manual mode, where you'll have complete control during high-performance or hilly driving.
All-Wheel Drive with Intelligent Control
The RDX all-wheel drive system is designed to help maximize the use of available traction in both dry and slippery conditions, while minimizing system-wide friction and power loss to help optimize fuel efficiency. In normal cruising, the system operates as an efficient FWD vehicle with 100% of engine torque being directed to the front wheels. During moderate acceleration or when front wheel slip is detected in dry conditions, 25% of engine torque is transferred to the rear wheels. On a wet or slippery surface, wheel slippage will cause a reduction in engine output to the front wheels possibly to a point torque is distributed 50/50 between the front and rear wheels. Systemic efficiencies allow the AWD system to operate at only one mile per gallon below the front-wheel drive model.
The RDX front strut and rear multi-link suspension systems are tuned to provide a combination of secure handling and exceptional ride. The RDX is also the first Acura model equipped with uniquely designed shock absorbers known as Amplitude Reactive Dampers. The front Macpherson strut design is configured to offer long vertical wheel travel and excellent durability that will stand up to under-maintained city streets. Stability is also enhanced by having a lower center of gravity than most SUVs, as well as a wide track and long, 105.7" wheelbase.
Grammy® award-winning recording engineer and producer Elliot Scheiner helped design the Acura/ELS Surround®32 Premium 10-speaker Sound System to reproduce music the way it is heard in the recording studio. As a result, surround sound fills the car from any stereo digital source. In addition to all the source inputs of the standard RDX audio system, features of the Acura/ELS system include:
Smooth & Quiet
While developing the second-generation RDX, one of our primary goals was to make the vehicle more enjoyable for both driver and passengers by reducing noise, vibration, and harshness. A floating front sub-frame structure with heavily reinforced mounting points reduces road noise. Thinsulate, an effective noise absorber, has been added to new areas such as the inner fenders, door lighting housings, and spare tire pan to further reduce road noise. Michelin Primacy MXM4 tires were also selected for their quiet performance.
