Acura Automobiles: 2013 RDX

Posted on 26. Mar, 2012 by in Acura Canada

Like a predecessor, a 2013 RDX rides on 4-wheel eccentric cessation that utilizes a MacPherson strut pattern in front and a multi-link pattern in back. However, a longer wheelbase, increasing lane breadth and a revoke core of sobriety assistance give a new RDX softened doing with a some-more pointed ride. Further optimized framework ascent points with increasing acerbity assistance beget some-more accurate handling. New framework record abounds in a 2013 RDX in a form of apparatus such as all-new Amplitude Reactive Dampers and a new suit adaptive electronic energy steering element that replaces a prior hydraulic steering.

The growth of new RDX concerned regulating a good doing qualities of prior era RDX and afterwards to supplement even some-more character. “High contrast” was a core thesis in a development- definition a new RDX looks some-more worldly and gentle on a outside, though still offers pushing pleasure with nothing of a normal SUV pushing dynamics. Such goals for energetic opening and plenty concentration were not easy to achieve, nonetheless Acura designers answered this plea by giving a RDX a low core of gravity. The outcome is an generally assured pushing experience- possibly in parsimonious corners on a towering highway or a open highway during a family trip.


Acura engineers total a car that transcends a normal SUV pushing experience. As a result, a 2013 RDX concurrently provides competition disposed pushing on twisty roads, well-spoken float characteristics on a highway and agreeable doing in a city.

Front Suspension
The eccentric front cessation used with a 2013 RDX is a specifically tuned MacPherson strut pattern with compress packaging. The cessation offers prolonged circle transport and a ruggedness compulsory to accommodate oppressive civic roads. The cessation geometry has been optimized with both a high caster angle and “trail” to yield pointy on-center steering response and stability.

Additional specifics of a front cessation that assistance grasp sports sedan-like doing include:

  • High-friction top strut mounts that yield good on-center steering feel, along with increasing linearity while shortening steering shimmy
  • Side-specific, symmetrically wound curl springs to urge steering quality
  • All-new Amplitude Reactive Dampers
  • Rebound springs
  • Large-diameter revoke arm correspondence bushing to assistance revoke NVH
  • Optimized kingpin blueprint to raise steering feel and linearity
  • A incomparable (22mm) hole anti-rollbar to assistance control physique hurl for agree cornering
  • Wider front lane breadth (+1.2 inch) than before

Rear Suspension
A multi-link pattern eccentric back cessation element with aluminum knuckles fits compactly underneath a back seating and storage areas of a RDX. The cessation uses large-diameter trailing arm bushings to revoke rudeness and urge float comfort. A special steel cessation subframe with vast “floating” bushings reduces NVH, while altogether fortitude improves interjection to stiffer ascent points due to a some-more firm back physique structure.

Rear cessation features:

  • Special anti-squat geometry to revoke physique pitching while underneath acceleration
  • All-new Amplitude Reactive Dampers
  • Rebound springs
  • 19mm hole back stabilizer bar helps broach agree cornering
  • Wider back lane breadth (+0.8 inch) than before


A new record for Acura, Amplitude Reactive Dampers are used on a 2013 RDX to yield a higher turn of float comfort together with crisp, accurate handling. The dampers work in dual graphic opening parameters, including a Ride Zone and a Handling Zone. Each section has a singular set of concentration and miscarry damping army tailored to yield a preferred float and doing attributes. In essence, a width reactive dampers work like dual apart cessation systems total in one. The new dampers are wholly automatic in operation with no wiring required.

Ride Zone
For brief cessation cadence (between 1-5 mm travel), a dampers yield minimal damping outcome to yield an intensely gentle float where tiny cessation transport is needed- such as on well-spoken highway surfaces.

Handling Zone
For longer cessation cadence (over 10 mm travel), a second damping circuit is engaged. Here damping outcome is maximized for extended steering feel, softened body-roll control and some-more secure handling- such as during assertive cornering or on serious highway conditions.

With a Amplitude Reactive Dampers, by adding a second open floating valve (the prior era RDX usually had one compulsory valve) above a compulsory categorical piston valve, a 2013 RDX is means to say a higher pushing dynamics of a prior model, and serve urge float qualities to that of a sedan.

For example, while pushing on severe surfaces, a concentration of short-stroke check transformation allows a categorical piston valve catch a tiny vibrations for a gentle ride. However during tough cornering both a categorical and second piston valves pierce that emanate a many incomparable damping force for softened pushing dynamics.

Input Separation Bushings
The 2013 RDX adds submit subdivision check mounts to a back cessation (previous indication usually had them in front), that supports a width reactive check to assistance urge float fortitude and pushing dynamics. The submit subdivision check mountain helps catch and some-more uniformly discharge damping army that are routinely upheld on to a body. For instance during cornering on severe surfaces, a check mounts send check force some-more good to a body, assisting to stabilise open movement.


The 2013 RDX creates use of an all-new Motion-Adaptive Electric Power Steering (EPS) system- a first-ever use for Acura. Standard on all 2013 RDX models, this worldly new steering element links a car fortitude support (VSA) and Electric Power Steering to assistance detect doing instability knowledge on sleazy roads as good as underneath braking. The element automatically triggers inputs that prompt a motorist to expostulate in a instruction to assistance lessen a inconstant pushing condition.

Motion-Adaptive Electric Power Steering (EPS)
Standard on all 2013 RDX models, Motion-Adaptive EPS is a worldly new element that incorporates pushing fortitude record that triggers steering inputs that prompt a motorist to expostulate in a scold instruction during cornering and when experiencing sleazy highway conditions.

Using car speed and steering angle data, Motion-Adaptive EPS works with Vehicle Stability Assist (VSA®) and Electric Power Steering to detect instability in low traction conditions (both during cornering and underneath braking) and automatically triggers steering inputs directed during call a motorist to expostulate in a scold direction. This new modernized record supports a driver’s movement in doing a car some-more safely and comfortably.

Noted subsequent are 3 examples of how Motion-Adaptive Electric Power Steering (EPS) functions in and with VSA.

Mitigates Understeer: Helps scold a steering inputs to lessen understeer and assistance a motorist snippet a dictated bend of a road.

Mitigates Oversteer: Helps scold a steering inputs to lessen oversteer and assistance a motorist snippet a dictated bend of a road.

Stabilizes Braking: Helps scold a driver’s steering submit to revoke car instability when a motorist is braking tough on highway surfaces with opposite attrition coefficients (such as cement that is usually partially lonesome with mud or snow).

With Electric Power Steering (EPS), a worldly electric power-assisted rack-and-pinion steering element takes a place of a compulsory hydraulic energy steering system. EPS responds now to steering submit and automatically changes a volume of energy support suitable to a vehicle’s speed.

The Motion-Adaptive EPS element consists of a rack-and-pinion steering rigging with an electric engine is located subsequent to sail axle. To control a turn of support a Powertrain Control Module receives signals from a speed sensor and, joined with a steering sensor for torque and rotation, afterwards calculates a optimal volume of support and sends a vigilance to a electric motor.

When compared to a operation of a compulsory hydraulic siphon energy steering system, a some-more elementary Motion-Adaptive EPS increases potency since it does not pull a continual volume of energy directly from a engine. Other advantages of electric power-assisted steering embody a simplicity, a revoke energy expenditure (which helps urge fuel efficiency), and a condensation (and ensuing revoke altogether weight).

The steering ratio on all RDX models is 15.0:1 (2012 RDX was 15.1:1), ensuing in 2.7 turns lock-to-lock (2012 RDX was 2.8 turns) and a curb-to-curb branch hole of 39.0 feet (2012 RDX was 39.2 feet).


With all new extraneous sheetmetal for 2013, a RDX also receives new large-diameter aluminum wheels and far-reaching tires that serve element a RDX’s extraneous design. RDX facilities as customary confidant new separate 5-spoke 18×7.5-inch aluminum wheels with specifically grown Michelin Primacy MXM4 P235/60R18 all-season tires designed with sold concentration on reduced highway sound and revoke rolling insurgency (improved fuel economy). Much time was spent tuning a tires so that sound and rudeness was reduced- though though negatively inspiring altogether doing performance.

The gangling tire is a space- and weight-saving T165/90R17 proxy section that is located in a building (under a cover) in a back bucket area of a RDX.


While a 2012 RDX supposing glorious interlude performance, for 2013 a RDX receives countless braking improvements per opening as good as safety. The front brakes now underline some-more firm singular piston cast-iron calipers that clamp incomparable hole (312 mm vs. 296 mm) rotors. For 2013, a front calipers have a special trim image that improves looks and prominently displays a Acura name. The 12.3-inch hole front rotors underline a Geomet cloaking for softened looks and combined decay prevention. In addition, a front rotors are a new pattern that incorporate some-more inner cooling vanes (60 vanes contra 42) to urge braking performance.

The back brakes underline 12.0-inch hole plain rotors (with Geomet coating) that group with singular piston cast-iron calipers. Both a front and back stop rotors bond to heart orientation that request new low-friction seals that revoke drag by approximately 20 percent.

For 2013, a cadence ratio of a stop pedal has been reduced by 7-percent that generates some-more assertive braking results.

An Anti-lock Braking System (ABS) with Electronic Brake force Distribution (EBD) is customary on a RDX. ABS helps a motorist keep car control during tough braking and EBD automatically proportions stop energy to a back brakes according to a car bucket and pushing conditions, assisting to urge interlude performance.

The RDX also has Brake Assist, that uses a microprocessor that recognizes a driver’s goal to fast request a brakes in a panic stop situation. In this case, Brake Assist immediately supplements a braking force, enabling a best braking opening in a impulse when it’s many needed. Brake Assist usually supplements a driver’s intentions, and a duty terminates immediately when a motorist releases a stop pedal.

In further to ABS and EBD, new electronic technologies embody with Hill Start Assist.

Hill Start Assist

New for 2013 is mountain start support (HSA) that helps forestall a RDX from rolling retrograde when a motorist switches from a stop to a accelerator while a car is stopped on a hill. When a highway slip exceeds a 5-percent slip and a car is entirely stopped in any brazen or Reverse rigging (with engine torque holding a vehicle), HSA self activates. The hydraulic stop modulator is tranquil by a longitudinal g-force sensor along with a circle speed sensor and steering angle sensor.

When mountain start support is active, a brakes momentarily reason as a driver’s feet rises off a brake. The brakes are automatically expelled when a motorist presses a throttle, sufficient expostulate torque is applied, and a car starts to pierce forward.


Vehicle Stability Assist™ (VSA®) is enclosed as customary apparatus on a 2013 RDX. By ceaselessly monitoring a vehicle’s doing parameters (such as car speed, stifle position, steering angle, particular circle speeds, parallel G-force and bend rate), VSA® detects if a car is about to knowledge oversteer or understeer.

To assistance scold possibly of these situations, 4-channel VSA® automatically reduces a engine’s energy outlay as needed, and relates one or some-more brakes away to assistance stabilise a chassis. The VSA® response is so discerning that a instability competence be corrected even before a motorist knows that it is occurring. Traction Control is integrated into a VSA® to assistance a RDX accelerate uniformly on sleazy surfaces. If required, Traction Control can be disabled.


Acura RDX has an onboard Tire Pressure Monitoring System (TPMS) that warns a motorist if a atmosphere vigour decreases significantly in any tire. The element helps revoke a possibility of deleterious a tire or losing control of a car due to low atmosphere pressure. This is critical since a delayed trickle competence not be simply detectable though could over time means poignant atmosphere detriment ensuing in detriment of hold or potentially a blowout.

TPMS uses a sensor mounted in any circle that ceaselessly monitors tire vigour and sends a coded vigilance to a TPMS electronic control section (ECU). The routine starts with a vigilance initiator located on a framework usually inboard of any tire. The initiator sends a singular vigilance for any TPMS sensor. Then a TPMS sensor sends tire vigour information to a TPMS ECU, that compares a values for any tire’s vigour opposite an excusable operation of pressures.

The Multi-Information Display (MID) can concurrently arrangement a atmosphere vigour in all 4 tires, creation it elementary to locate a low-pressure tire.


The RDX’s 16-gallon fuel tank is located in a stable position underneath a physique and brazen of a back wheels. The RDX has an EPA estimated* city/highway/combined fuel economy of 19/27/22 mpg (AWD) and 20/28/23 (2WD), that gives it an estimated highway operation of approximately 430 miles (AWD) and 450 miles (2WD) miles on one tank of fuel. The use of Premium fuel is endorsed (but not required) for a 3.5L V-6 engine in a 2013 RDX.

*Based on 2013 EPA mileage estimates. Use for comparison functions only. Your tangible mileage will change depending on how we expostulate and say your vehicle.


For combined utility, a RDX has a 1,500-pound draw rating when versed with a accessible towing package. The draw rating creates a RDX able of pulling apparatus such as a tiny camping trailer, a motorcycle trailer or a personal watercraft.


Like all products from Honda of America Manufacturing’s trickery in Marysville, Ohio, a RDX follows despotic discipline for environmental care- both in a production routine and in a tangible car components. The 2013 RDX is done with U.S. and globally sourced parts. The following is a prejudiced list of environmental processes used in formulating a RDX that reduces a long-term environmental impact.

  • More than 90-percent of RDX tools are done of recyclable materials
  • The use of non-chromed dark-skinned leather reduces dangerous rubbish era during a tanning process
  • Elimination of PVC in many interior tools and extraneous improves recycling ability
  • Wheel change weights and electro-deposition paints do not enclose any lead
