ENGINE
As Acura's first Entry Premium SUV, the RDX was the focal point of the development of a special powertrain that would blend 4-cylinder efficiency and 6-cylinder power. The ideal solution came in the form of an innovative new variable flow turbo (VFT) that delivers an unusually broad powerband with little or no lag in throttle response. The RDX is equipped with an all-new 2.3-liter DOHC 16-valve in-line four-cylinder engine with i-VTEC valve control that combines Variable Valve Timing and Lift Electronic Control (VTEC) with Variable Timing Control (VTC). With the variable flow turbo working in concert with i-VTEC, the RDX delivers strong power and torque, excellent fuel economy and very low emissions.
Rated output for the RDX engine is 240 horsepower SAE net at 6000 rpm. In terms of torque, the RDX has the highest output of any engine in the Acura lineup, with 260 lbs.-ft. of torque SAE net at 4500 rpm. The RDX is expected to return an EPA-estimated 19/24 City/Highway mileage, while meeting strict CARB LEV-2 ULEV and EPA Tier-2 Bin-5 emissions standards.
4WD SYSTEM & TRANSMISSION
A 5-speed automatic transmission with Sequential SportShift is standard. The electronically controlled drive-by-wire throttle and transmission work together to execute shifts, resulting in exceptionally quick and smooth gear changes. The transmission can function as a conventional automatic transmission or, at the driver's option, can be shifted manually via steering-wheel-mounted paddles.
SH-AWD(TM) is standard in the RDX to maximize available traction while improving handling balance and responsiveness. SH-AWD(TM) is Acura's patented all-wheel drive system that distributes the optimum amount of torque not only between the front and rear axles but also between the left and right rear wheels.
INTERIOR
Inside the RDX, the front-seats feature a high "eye point" that provides a confident field of view. The 3-passenger rear seat has a 60/40 split-folding capability and, when folded flat, significantly expands the load area and increases the cargo volume to 60.6 cubic feet of storage. There are multiple interior storage compartments positioned throughout the interior, including a large (and lockable) dual-level center console located conveniently between the front seats that can securely accommodate a briefcase.
The RDX features an array of electronic features that set it apart from the competition. These include a dual-zone automatic climate control system, a Multi-Information Display (MID), and LED backlit gauges with progressive illumination. Also standard is an impressive 360-watt 7-speaker Acura Premium Sound System with a multi-format 6-disc changer, AM/FM tuner, XM(R) Satellite Radio, and the convenience of an MP3/auxiliary input jack for easily connecting audio devices such as an iPod.
