The worldly new 2019 RDX framework pattern combines with a some-more organisation and lightweight physique structure to yield some-more enchanting and assured handling, incomparable refinement, and aloft float comfort.

The RDX’s increasing wheelbase, front and back lane widths, softened front-to-rear weight balance, polished front MacPherson strut and all-new five-link back suspension, and increasing circle and tire sizes all raise float peculiarity and opening and yield glorious control for a driver.

Two check forms are accessible – Amplitude Reactive Dampers on a customary RDX, Technology Package and A-Spec, and Acura’s innovative Active Damper System on a Advance Package. All RDX grades embody front hydraulic cessation bushings for softened siege from highway noise, quivering and rudeness (NVH).

All grades also underline Acura’s 4-mode Integrated Dynamics System, tranquil by a distinguished expostulate mode dial on a vehicle’s core console.  With Comfort, Sport, Sport+ and Snow modes, a motorist can dial in a energetic opening characteristics of a car according to their enterprise and prevalent highway conditions.  The Integrated Dynamics System interacts with mixed energetic systems in a vehicle, including a Drive-By-Wire™ throttle, Electric Power Steering, torque-vectoring SH-AWD™ (when equipped), Active Sound Control (ASC) and, on a RDX with Advance Package, a Active Damper System.

Confidence and Control
A new dual-pinion, non-static rigging ratio Electric Power Steering (EPS) complement also contributes to a RDX’s accurate and secure steering feel. Vehicle Stability Assist™ (VSA®) with Traction Control and a 4-channel Anti-Lock Braking System (ABS) with Brake Assist, and a new electronic stop upholder (EBB) supplement to a RDX’S capability. An Electric Parking Brake (EPB), Automatic Brake Hold and Hill Start Assist supplement welfare in trade or on hills.

All RDX grades underline aluminum amalgamate wheels as customary equipment, with diameters trimming from 19 inches on a RDX, Technology and Advance Packages, to 20 inches on a A-Spec. In both front-wheel expostulate (FWD) and Super Handling All-Wheel Drive™ (SH-AWD®) versions, all-season tires safeguard surefooted opening in a far-reaching operation of highway and continue conditions.

Optimized Weight Distribution
Handling change is contingent on cessation pattern and unibody constructional stiffness, though it also requires determining a member weight and wrapping to idealize a vehicle’s core of gravity. During a redesign for 2019, RDX engineers changed a core of sobriety 3.1 inches rearward. This resulted in an softened front/rear weight placement of 57/43-percent compared to a prior era RDX’s 60/40-percent front/rear weight placement for AWD variants. The alleviation helps a RDX boldly in probably all pushing conditions, generally during energetic cornering and puncture deterrence maneuvers.

Front and Rear Suspension
The 2019 RDX cessation delivers both flexible doing and a composed, movable ride. The complement uses a multiple of front MacPherson struts and a back five-link design, both utilizing organisation subframes and front regulating hydraulic cessation bushings. The RDX, Technology Package and A-Spec use 2-stage Amplitude Reactive Dampers, while a Advance Package’s Active Damper System is electronically integrated with a vehicle’s Integrated Dynamics System (IDS). Ground clearway is a useful 8.2 inches, permitting all RDX grades (including FWD and SH-AWD®) to navigate by some-more sundry conditions.

The RDX’s strut-style front cessation improves pile-up performance. The new five-link back cessation provides superb doing characteristics and float quality, while also assisting to maximize second-row seating and load space. On all RDX grades, 30 mm tubular front and 23 mm plain back stabilizer bars urge turn-in response while shortening physique hurl during cornering. The stabilizer bars are connected to their ascent bushings and use low-friction joining links for well-spoken operation. The curb-to-curb branch hole is 38.9 feet for all grades.

MacPherson Strut Front Suspension
The MacPherson strut front cessation is engineered to yield desirous doing opening and a manageable feel for a driver. Specially calibrated geometry ensures a high grade of speed and precision, fibre and stability. The revoke cessation arms are connected to a subframe and to a physique around hydraulic correspondence bushings, providing a ideal multiple of doing responsiveness and precision, along with limit siege from highway noise, quivering and rudeness (NVH).

Five-Link Rear Suspension
The 2019 RDX’s new five-link back cessation complement offers both float correspondence and doing opening significantly above a prior generation, putting a RDX in a same joining boldly as tip European competitors. This new multi-link complement uses a steel subframe, fake aluminum top control arms and toe couple to minimize unsprung weight and optimize member stiffness, an aluminum heart carrier, and high-strength steel revoke control arms that yield serve weight savings. Improvements to a RDX’s unibody rigidity – quite in a back area – assistance a new cessation complement to surpass during improving stability, float compliance, and impact harshness. The complement is designed to perform ideally in both a FWD and
SH-AWD® configurations.

Hydraulic Suspension Compliance Bushings
The front cessation complement uses hydraulic correspondence bushings mounted in aluminum carriers for optimal float peculiarity and quivering isolation. These bushings are privately tuned to minimize a volume of quivering that is eliminated to a occupants, shortening a altogether noise, quivering and rudeness (NVH) inside a vehicle.

Amplitude Reactive Dampers (RDX, Technology Package and A-Spec)
Proven Amplitude Reactive Dampers are used on a RDX, Technology Package and A-Spec. Amplitude Reactive Dampers minister to superb float comfort together with crisp, accurate handling. The dampers work in twin graphic opening parameters, including a Ride Zone and a Handling Zone. Each territory has a singular set of application and miscarry damping army tailored to yield a preferred float and doing attributes. In essence, a width reactive dampers work like twin apart cessation systems sum in one. The dampers duty reactively or “passively,” and are wholly mechanical/hydraulic in operation with no wiring required.

Active Damper System (ADS) (Advance Package)
New to a 2019 RDX in a Advance Package, a Active Damper System is partial of a vehicle’s Integrated Dynamics System (IDS) that also controls a Electric Power Steering (EPS), Drive-by-Wire™ stifle system, Vehicle Stability Assist™ (VSA®) and traction control. Controlled by a microprocessor regulating information from a Vehicle Stability Assist (VSA) system’s circle sensors, yaw/G sensor, engine rpm and torque, and steering angle, a Active Damper System can adjust any 0.002 seconds to adjust particular wheels to highway surfaces.

The core console-mounted expostulate mode dial allows a motorist to select between Comfort, Sport, Sport+ and Snow modes. As destined by a pushing mode controller, an electric actuator integrated into any check governs hydraulic fluid movement inside a unit. Damper settings are automatically calibrated to a pushing mode environment to grasp a following benefits:

  • Snow and Comfort – Provides a courteous change of float and doing for bland pushing conditions.
  • Sport – This mode provides firmer check settings that squash and stabilise a car physique during fast steering inputs and maneuvers. Steering and AHA torque vectoring are also noticeably sharpened, boosting doing pointing and altogether responsiveness.
  • Sport+ – Further increases cessation damping force while maximizing steering response and AHA torque vectoring for a many intent motorist who final a many accurate car response.

At a driver’s preference, possibly a Comfort or Sport mode might be set as a IDS default on car startup.

Dual-Pinion Variable-Ratio Electric Power-Assisted Rack-and-Pinion Steering (EPS)
In a initial for RDX – and also in a shred – customary Electric Power Steering (EPS) incorporates twin sail gears and a non-static rigging ratio for unrivalled steering feel, opening and comfort. Compared to a normal single-pinion steering system, a twin sail EPS utilizes a earthy steering submit from a motorist as good as from a supplemental electric motor. A non-contact torque sensor measures a driver’s steering bid and an ECU determines how most electric engine support to apply, ensuing in smooth, healthy and accurate steering feel.

The system’s non-static steering ratio is enabled by a steering rack, that utilizes gradually wider rigging spacing so, as a circle is changed over off center, a steering ratio is effectively increased, providing for both easy maneuverability in parking and city travel maneuvers and superb patience and fortitude when roving during turnpike speeds The steering ratio is non-static with an on-center ratio of 15.13:1 and final off-center ratio (at full lock) of 11.95:1, with a sum of 2.23 turns lock-to-lock (compared to 2.73 on a previous-generation RDX).

The EPS is calibrated with a Integrated Dynamics System to raise steering response and boost feel in a Sport mode, and even serve in a Sport+ mode.

Four-Wheel Disc Brakes with ABS, Electronic Brake Booster (EBB), Electronic Brake Force Distribution and Brake Assist
Four-wheel front brakes with 4-channel (ABS), electronic stop upholder (EBB), electronic stop force placement (EBD) and stop support are customary on a 2019 RDX. The complement utilizes a large-diameter master cylinder to grasp a short-travel, organisation pedal feel. The EBB uses an electronic servomotor to support braking opening while improving stop feel and pedal modulation in probably all conditions. The outcome is a gentle and polished braking feel during low speeds, predicted and easy operation on a highway, a sporty feel on circuitous roads, and calming high-performance interlude in puncture situations.

The 12.4-in. ventilated front stop rotors are clamped by twin-piston calipers. The back front brakes incorporate plain rotors interconnected with single-piston stop calipers. The low-friction pattern of a stop calipers reduces appetite waste when a brakes are not in use, directly improving fuel efficiency.

Vehicle Stability Assist™ (VSA®) with Traction Control
Vehicle Stability Assist™ (VSA®) is an electronic fortitude control complement that works in and with a RDX’s Drive-by-Wire™ stifle and a 4-channel ABS systems to raise control capability while a car is accelerating, braking, cornering or when a motorist creates a remarkable maneuver.

VSA® also provides a limited-slip differential outcome by requesting braking force to a slipping wheel, thereby redirecting pushing force to a circle with some-more traction. While a motorist can revoke a traction control efficacy permitting some-more circle trip during stranded conditions by dire a VSA® button, ABS stays entirely operational during all times.

Integrated Dynamics System (IDS)
The Integrated Dynamics System (IDS) on a 2019 RDX automatically and seamlessly excellent tunes powertrain, framework and Active Sound Control complement functions on a continual, real-time basement to maximize car opening and motorist delight regardless of conditions. Four driver-selectable modes embody Comfort, Sport, Sport+ and Snow. Drivers might preset Comfort or Sport as their default mode, while Snow and Sport+ modes can be comparison on a fly.

Agile Handling Assist
Agile Handling Assist uses a vehicle’s brakes selectively to urge initial branch response, boost altogether cornering ability, and allege motorist confidence. By regulating stop vectoring – requesting braking force to a inside wheels – during cornering during high parallel G, a complement creates a “yaw moment,” so generating some-more branch force and shortening understeer.

Hill Start Assist
The Hill Start Assist duty helps to forestall a car from rolling retrograde when a motorist switches from a stop pedal to a accelerator pedal while a car is stopped on a hill. Hill Start Assist automatically activates when a car senses a certain slip and is entirely stopped in any brazen rigging when confronting adult mountain or in retreat rigging when confronting downhill. The complement uses a longitudinal G-sensor along with a circle speed sensor to control a hydraulic stop modulator. When activated, Hill Start Assist will recover a brakes when a motorist depresses a stifle or if a motorist doesn’t press a accelerator after a few seconds.

Electric Parking Brake (EPB)
The customary Electric Parking Brake (EPB) is simpler, some-more accessible and gentle to use than a normal parking brake. The EPB also frees adult core console space, permitting a aloft console and an extended armrest length.

Engaging a parking stop requires usually a lift on a switch on a core console. To recover a parking brake, a motorist simply presses on a accelerator pedal while a seatbelt is buckled when a delivery is in Drive or Reverse or else pushes on a parking stop switch while handling a stop pedal.

Automatic Brake Hold
When activated, Automatic Brake Hold retains stop vigour when a car comes to a stop such as during a trade light or in complicated traffic. This frees a motorist from ceaselessly dire a stop pedal to say a car in a stopped position until a motorist presses a stifle pedal.

Operating a complement requires twin elementary actions from a driver:

  • Activating/deactivating a complement around a switch on a core console
  • Pressing on a stop pedal until a car comes to a stop

Once these stairs are taken, Automatic Brake Hold will prove rendezvous and afterwards say stop vigour when a car has come to a stop, even if a motorist after releases a stop pedal. A immature “Brake Hold” idol on a instrument row illuminates to uncover that a complement is functioning. The RDX afterwards stays stopped – even on a mountain – until a motorist presses a accelerator pedal. At this point, Automatic Brake Hold releases a brakes and a car resumes normal braking function.

Wheels and Tires
The new RDX comes customary with 19-inch aluminum amalgamate wheels (RDX, Technology, and Advance Packages. These new wheels are one-inch incomparable in hole than those of a prior RDX. To raise cornering performance, a A-Spec facilities 20-inch aluminum amalgamate wheels, a initial for any RDX model. Each RDX indication facilities a possess singular circle design.
