Acura MDX

The Acura MDX is a mid-size luxury crossover SUV with three-row seating produced by the Japanese automaker Honda under its luxury Acura division since 2000. The alphanumeric moniker stands for "Multi-Dimensional" luxury. It has ranked as the second-best selling mid-size luxury SUV after the Lexus RX.

The MDX is the first luxury crossover SUV to have standard third-row seating, and shares its platform with the Honda Pilot. The Pilot was made available with an eight person seating configuration, while the MDX exclusively seats seven, with two seating positions in the third row. The MDX was introduced on October 5, 2000 as a 2001 model, replacing the slow-selling U.S.-only body-on-frame SLX, based on the Isuzu Trooper. In Japan, it was made to replace the Honda Horizon (also based on the Trooper) which was discontinued in 1999. In 2003, the vehicle went on sale in Japan and Australia as the Honda MDX; sales with Honda badges ended with the introduction of the second generation three years later.

First generation (YD1; 2001)

Derived from Honda's Global mid-size platform which underpins cars like the Honda Accord, Acura TL, TSX and Odyssey, it is powered by a '' J35A3'' 3.5 L SOHC 24 valve V6 engine with VTEC. Curb weight is , with a wheelbase and of ground clearance. The cargo floor can flip up to provide two additional seats. The vehicle is designed to hold 7 passengers, but the third row seats are small and only seat two, in contrast to the Odyssey and Pilot whose third row holds three passengers.

The vehicle features an automatic four wheel drive system (named VTM-4) that engages during off the line acceleration as well as when wheel slippage is detected. Additionally, the system offers a lock mode which can be activated and operated at low speeds and provides permanent 4WD and the equivalent of a locked rear differential; designed for climbing steep hills and getting out of stuck situations. To reduce drivetrain noise and increase fuel efficiency, the system runs as front wheel drive during normal cruising. The VTM-4 AWD system in the MDX has the same design as the VTM-4 systems found in the Honda Pilot and Honda Ridgeline. It is different than Honda's "RealTime AWD" system in the Honda CR-V and other models in that it can lock and it attempts to predict when traction will be lost and apply power to all four wheels before slippage occurs (by monitoring throttle inputs).

The navigation system and DVD entertainment system (also popular on other Honda/Acura models, such as the CR-V and Odyssey) options were mutually exclusive in the 2002 model. Both could be ordered at the same time since the 2003 model. The navigation option comes with a backup camera since the 2003 model. Since 2005, the navigation system featured information from Zagat about restaurants and other points of interest. The 2003 model was rated as Ultra Low Emission Vehicle. The United States Environmental Protection Agency estimates highway and city.

The first two model years' 3.5-litre V6 engine produces and of torque from 3000 to 5000 rpm. For the 2003 model, the engine was improved to produce 20 hp (15 kW) more power than the earlier models, and the wheel designs were updated. The 2004 through 2006 engine received a modest increase in power and produces and . The 2004 model is credited with a top speed of 137 mph, and a 0-60 time of 7.1 seconds. The 2004 model features dual tail pipes instead of the single pipe in earlier models, side curtain airbags, new head lights and tail lights, and new wheels. Some chrome trimmings on the 2004 model use matte finish to distinguish from the polished shiny finish on earlier models. Little changed for the MDX during the 2006 model year with a few minor revisions to the vehicle's chrome and faux wood interior trim which could now be had with a dark grey wood (as opposed to reddish wood on earlier models), and also a black dash and steering wheel in tan interiors.

Second generation (YD2; 2007)

On April 11, 2006, Acura unveiled the 2007 Acura MD-X Concept during the New York International Auto Show, showing to the public an indication about the exterior styling of the upcoming completely redesigned MDX. The second-generation MDX was released on October 17, 2006 in the U.S.

The second generation model's body has a wider track and longer wheelbase than the previous MDX, but visibility to the rear has worsened from the prior generation. The redesigned Acura MDX's unit-body was engineered with Honda's Advanced Compatibility Engineering (ACE) body structure designed to absorb energy from a collision. The suspension was tuned at Germany's Nürburgring race track. The engine was upgraded to a 3.7-liter (3664 cc) V6 tuned for at 6,000 rpm and of torque at 5,000 rpm. It accelerates from 0 to 60 mph in 6.5 seconds and is estimated by the EPA to consume in the city and on the highway. It is one of the most powerful engines Honda has produced to date. The "VTM-4" all-wheel drive system on the previous generation was replaced by the new SH-AWD "Super Handling All-Wheel Drive" previously debuted on the 2005 Acura RL. This AWD system is one of the most advanced in its class, featuring an active rear differential often found on high performance cars. The MDX is able to tow .

Like many Acura models, the MDX comes with a power sunroof, leather interior, and high-intensity discharge (Xenon) low-beam headlights. For the 2007 through 2009 model years, three option packages were available: Sport, Technology and Entertainment.
* The Technology Package includes the Acura/Alpine DVD-based satellite GPS navigation system with AcuraLink satellite communications with real-time traffic reporting (XM NavTraffic), a 410-watt Acura/ELS DTS Surround audio system with XM Satellite Radio, backup camera, and a remote powered liftgate, operated either from the key's remote, inside the car or directly from the lift gate.
* The Sport Package featured active suspension dampers (co-developed by Honda and Beijing West Industries) that dynamically improves handling according to road conditions with a button in the center stack to switch to Sport/Comfort modes. This Comfort/Sport mode uses magneto rheological dampers, which change their characteristics when a magnetic field is introduced (usually in milliseconds). The Sport package also includes unique 5-spoke aluminum-alloy wheels, perforated leather seats and the items in the Technology package.
* The Entertainment Package offers a flip-down LCD screen with 2 wireless Dolby Digital headphones, second-row heated outboard seats, and a unique center-stack silver trim. The Entertainment Package is only available on Sport or Technology Package models as compared to the 1st Generation MDX where the Entertainment Package was available as a standalone package on Touring Models.

All Canadian Acura MDX models, aside from the heated front seats, also get the second-row heated outboard seats as standard equipment as well. A feature unique to Canadian MDX models are headlight washers. In terms of packages, Canadian MDX models get only two: Technology and Elite. The Technology package corresponds essentially to the US model's Technology package while the Elite package is an amalgamation of the US model's Sport and Entertainment packages. However, AcuraLink real-time traffic reporting through XM NavTraffic is unavailable for Canadian MDX models.

Like the first generation model, the new generation is manufactured exclusively by Honda of Canada Manufacturing Ltd. in Alliston, Ontario, Canada. But along with the 2007 RDX, the new MDX was the first Acura model to pass the Acura Quality Line, a special quality control and verification process separate from the other Honda vehicles.

For 2008 the MDX received a new auto-dimming rearview mirror. The 2009 MDX had added more upgrades to the navigation system and there are two new colors added. The power tailgate, previously available only with the Entertainment package, is now included with Technology and Sport packages.

In 2010, the MDX received a facelift adopting to Acura's new "Power Plenum" grille that debuted on its 2009 model year sedans. The most important upgrades to the 2010 model where a new paddle shift six-speed SportShift automatic transmission with downshift Rev-matching, and an increase in compression ratio to 11.2:1 with forged aluminum pistons to replace the previous 2007–2009 3.7L's 11.0:1 pistons. Structural rigidity was improved for the 2010 model year. An Advance Package became available that included Adaptive Cruise Control, blind spot monitor, Active Damper suspension, collision mitigation braking system, wider 7-spoked 19 inch wheels and tires, Premium Milano leather ventilated seats and auto leveling headlights. Non-navigation equipped MDX models now have a backup camera monitor located in the rear-view mirror.

The redesigned MDX overtook the TL as Acura's top seller in the United States.

Third generation (YD3/4; 2014)

The 2014 MDX Prototype was unveiled at the 2013 North American International Auto Show, the production version was revealed at the New York Auto Show. Production began on May 2, 2013; vehicle assembly shifted from Ontario, Canada to Lincoln, Alabama. US sales began on June 20.

The MDX is powered by a 3.5-liter direct injected Earth Dreams V6 with Variable Cylinder Management. A front-wheel drive (FWD) model is available for the first time, in Canada all-wheel drive remains the only configuration offered. EPA-estimated fuel economy is improved with all-wheel drive ( SH-AWD) models rated at // (city/highway/combined) and FWD models rated at // (city/highway/combined).

The headlights are Acura's Jewel Eye LED Headlights (first introduced on the RLX). Each headlamp uses five separate LED sources with three used for low-beam lighting and two for high-beam lighting. LED bumper mounted fog lamps are offered as a dealer installed option.

The interior reduced button clutter by adding a 7-inch touchscreen with haptic feedback, an additional 8-inch screen is also standard. To reduce interior noise an acoustic ( PVB layered) windshield, acoustic front door glass and thicker rear glass are used as well as triple sealed door openings. Advance package models include further noise reduction using a thicker carpet base layer and front fender liners. The seating H-point has been reduced.

According to Acura the exterior is more aerodynamic reducing drag by 16% with the new model lapping Nürburgring 8 seconds faster than its predecessor. The steering gear ratio is 9% quicker for a more sporty feel. The MDX rides lower reducing its center of gravity, to reduce unsprung mass the front suspension lower control arms are made from forged aluminum. Structure rigidity is improved and weight reduced through increased use of high-strength steel. Overall, 64% of the total vehicle body mass is high strength steel (HSS), aluminum and magnesium. HSS makes up 59% of vehicle body mass; 1,500  MPa yield strength steel makes up 7%. A single ring-like hot stamped HSS outer door ring component reinforces the A-pillar, roof rail, B-pillar, and lower floor rail encircling the front doors for improved crash protection. Acura states that after conducting a simulated IIHS 25% small offset frontal crash test the front doors will open with normal force.

The updated Adaptive Cruise Control adds low-speed stop-and-go functionality. In terms of safety the MDX adds a standard driver's knee airbag, optional Lane Keeping Assist System and Collision Mitigation Braking System.

MY 2016

Acura swapped the Honda 6-speed automatic transmission for a ZF 9-speed automatic and changed the SH-AWD system for 2016. The revised SH-AWD system uses a hydraulically-controlled clutch and is similar to system found in the TLX.

MY 2017 facelift (YD4)

A refreshed for 2017 model year MDX went on sale in June 2016, and features a diamond pentagon front grille which debuted on the Acura Precision Concept, redesigned LED headlamps with automatic high beams, LED DRL light pipes and LED amber light pipe turn signals. Restyled LED fog lamps are optional from the factory. MDX models will come standard with AcuraWatch which includes forward collision warning (with automatic emergency braking), lane departure warning (with lane keep assist) and Adaptive Cruise Control. A 360-degree surround view camera is optional. To reduce body mass the front fenders switched from steel to an aluminum panel.

Hybrid

A 3.0-liter V6, 7-speed dual-clutch, 1.3 kWh lithium-ion battery hybrid called the MDX Sport Hybrid was added to the lineup. The front wheels are powered by the engine and a single electric motor while the rear wheels are powered by twin electric motors (tri-motor). The hybrid was only available in all-wheel drive. Acura's Active Damper System is standard. Sales began in April 2017.

MY 2019

For 2019, the Active Damper System is available for non-hybrids, the front seats feature 4-way power lumbar. During the 2018 New York International Auto Show, alongside the debut of the third generation RDX, Acura announced the introduction of the A-Spec appearance package. The exterior features black and dark chrome accents, replacing all the chrome and rides on 20" grey aluminum wheels. The bumpers are redesigned to give the A-Spec a more sharp and aggressive design. Red leather seats with black alcantara inserts is now an option for the A-Spec package. Other changes for the A-Spec trim are new gauges, carbon fiber trim, sport pedals, and thicker steering wheel with paddle shifters.
