2018 Acura RLX Complete In-depth Review & Buying Guide

A combination of beauty and power, the 2018 Acura RLX wields some striking hardware. The sedan gets a refreshed look but what's under the hood is even better as the hybrid trim borrows its powertrain techs from the NSX supercar.

There are two engines to choose from, the standard variant gets a 3.5 L V6 engine while the hybrid trim pairs the same engine with three electric motors to generate 377 horsepower. A 10-speed automatic transmission is standard on the base but the hybrid engine is mated to a 7-speed dual clutch transmission.

Expert Review

CARHP Editorial September 21, 2018


Overall Rating

The RLX has its share of flaws as well. The interior design and infotainment system feels antiquated. Also, one would be happy to have more engine options and trims. Prices for the luxury sedan starts at $54,900.

2018 Acura RLX Features


Acura has kept things simple by offering RLX in two trims. The base gets a 3.5 L V6 engine that sends power to front wheel drive via a 10-speed automatic transmission. It also comes loaded with a plethora of techs and features that is more than what the competitors offer. The Sports hybrid meanwhile pairs the same engine with a dual clutch seven-speed transmission and three electric motors to generate a combined power of 377 hp.

Trims P-AWS w/ Technology Pkg Sport Hybrid w/ Advance Pkg
MSRP $54,900 $61,900
  • FWD Precision All-Wheel Steer (P-AWS)
  • Agile Handling Assist
  • 10-speed sequential sport shift with paddle shifters
  • Variable cylinder management
  • 3-Motorsport hybrid super handling all-wheel drive (SH-AWD) system
  • Idle stop
  • 7-speed dual clutch transmission
  • Electronic gear selector

We Recommend

Out of the two variants, the Sports Hybrid model is highly recommended with a price tag $61,900. The Hybrid RLX gets all the optional safety and comfort features and comes with all-wheel-drive precession system. The only drawback with this trim is that you will have to compromise on the trunk space.

2018 Acura RLX Engine


"Acura offers the choice between a gasoline-only and a hybrid powertrain for the 2018 RLX. Both feel refined and smooth, have excellent fuel economy ratings, and are powerful enough to move this large luxury sedan with ease. While the RLX has an adequate amount of agility, it isn't very sporty or engaging. It also doesn't offer as comfortable of a ride as some competitors"-Cars.usnews.com

Engine and Transmission

Acura offers the choice between a gasoline and a hybrid powertrain for the 2018 RLX. The base trim P-AWS is powered by a 3.5-liter V6 engine that churns out 310 horsepower and 272 pound-feet of torque. A 10-speed automatic replaces the 6-speed automatic this year and comes standard on the base along with the front-wheel drive.

The Sport Hybrid meanwhile comes loaded with the same V6 engine along with three electric motors, two of which sends the power to the rear wheels in order to provide all-wheel drive experience. A seven-speed dual clutch transmission is standard while the hybrid puts out a combined output of 377 horsepower and 341 pound-feet of torque.

The standard Acura RLX with 3.5L V6 accelerates from 0-60 MPH in 6.2 seconds and does a quarter mile in 14.2 seconds. The hybrid model with three electric motors and a 7-speed Dual clutch automatic transmission accelerates even better. It is not the fastest among its competitors but has an upper hand in terms of the overall package.

Handling and Steering

Acura’s All Wheel Steering delivers smooth and predictable handling. On curvy roads, the P–AWS system turns the rear wheel slightly in order to increase the stability. The RLX hybrid meanwhile does not get the P–AWS system, but it does come with Acura’s Super Handling All Wheel Drive. The sedan cruises effortlessly and absorbs most of the bumps in the road while offering a luxurious ride.


The RLX has a decent amount of bite that comes from 12.3-inch front ventilated discs and 12.2-inch rear solid discs. This helps the RLX to stop from 60 to 0 in 121 ft. which is not the best in class. The Lincoln Continental Premier leads the competition by having stopping power of 110 feet.

2018 Acura RLX Fuel Economy


The Acura RLX is economical as the standard variant is rated at 20 MPG city,29 MPG highway and 23 MPG combined. The hybrid variant with the three electric motors improves things and check in at 28/29/28 MPG. Acura gets tough competition from the Lexus GS which leads the segment with 29/34/31 MPG.

2018 Acura RLX Interior


"The 2018 Acura RLX has spacious, comfortable seats and lots of standard features. There's more room in the back seat than in many of the RLX's competitors, but its trunk size falls on the opposite end of the spectrum. The dual-screen infotainment system is not as high-tech or easy to use as some"-Cars.usnews.com

Seating and Comfort

The interior quality is top-notch as one would expect. Entry and exit are made easy by the big wide opening doors. The tilt and telescoping steering wheel and highly adjustable front seats make for a comfortable driving position. Speakers in the windshield pillars create large blind spot but the issue can be taken care off by opting for an Advance package that includes multiple cameras.

The 2018 Acura RLX accommodate five passengers and both the front and the rear seat have aggregable amount of space. Seats are supportive and cushioned all around. For child safety, the Acura gets two tether anchors and two sets of lower anchors in the back seat. Seating feature includes:

  • A leather-wrapped steering wheel and heated
  • 12-way power adjustable front seats
  • Ventilated front seats (RLX Sport Hybrid)
  • Heated outdoor rear seat (RLX Sport Hybrid)
  • Heated steering wheel (RLX Sport Hybrid)

2018 Acura RLX gets the same outdated infotainment system from the outgoing model. The Navigation system is slow as compared to the latest technology available among competitors. The dual-screen infotainment system only complicates things. The user interface looks antiquated and doesn't match up to the standards of a luxury sedan.


Truck space stands at 14.9 cubic feet of the RLX and 12 cubic feet in the hybrid model. These numbers are unimpressive for a small car as the rear seats also don’t fold down. The RLX fails to win over its competitors as the Cadillac XTS has a total of 18 cubic feet of trunk volume which is best n the class.  Even the Lincoln Continental and the Lexus GS offer better trunk space than the Acura.

2018 Acura RLX Exterior


"RLX gets a diamond-pattern grille with an outline like the nose applied to the MDX, as well as LED taillights, and a rear diffuser formed from gloss-black plastic. It also has more lines stamped into its hood"-The Car Connection 

Dimension and Weight

The 2018 Acura RLX is longer than the outgoing model which means there is more legroom on the inside. It is although not the longest in this segment but has a decent amount of space for five people. The RLX has 112.2 inches of wheelbase, same as the Lexus GS 450h.

2018 Acura RLX Competition

Acura RLX Vs Cadillac XTS

The new Cadillac XTS standard is priced higher than the RLX. The Cadillac wins over the RLX in terms of interior quality. It feels more modern and sophisticated. The Cadillac has excellent ride comfort, thanks to the new Magnetic Ride Control System.  The top variant of Cadillac XTS gets 20-inch alloy wheels, which look great as compared to the 19-inch alloy on both the Acura variants. Cadillac XTS also has better cargo space.

Acura RLX Vs Lincoln Continental Premier

The Lincoln is not as aggressive as the Acura RLX, rather it is more subtle and royal looking. Lincoln looks great with light color scheme and rich interior design. It also has more trunk space and a roomy interior as compared to Acura.

2018 Acura RLX Vs Lexus GS 450h

The Lexus GS 450h is a pretty looking car. Lexus gives more engine and trim options for you to choose. Whereas, the RLX has just two variants. The GS 450h comes with a rear wheel drive package, which makes it a driver's car. The 3.5L V6 pumps out 338 hp and does 60 mph in just 5.6 seconds.  On the inside, Lexus gives a decent amount of space and luxury options. There are not as many standard features that one gets on the Acura RLX but it has modern styling cues which makes it stand out from others.

2018 Acura RLX Final Verdict

The all-new redesigned 2018 Acura RLX is no doubt a good-looking car with a striking design. The front fascia is fully revamped and the new colors on offer makes the car more stunning. The RLX is undoubtedly a sporty, luxurious and a daily drivers car.
