2018 Acura RLX Hybrid Sedan

in Sedans
2018 MODEL



Detailed Review

The largest sedan from Honda 's upscale sister brand - The Acura RLX, since its introduction in 2014 has been long dwarfed by competing models from the likes of Mercedes-Benz and Audi. But after a much needed mid-cycle refresh and a sportier hybrid version, Acura has finally revealed the 2018 Acura RLX hybrid sport.

Stunning build and design

Fast and fuel efficient acceleration

Spacious cabin luxurious seating


Absence of Apple CarPLay and Android Auto

Interiors feel a little outdated

Lack of customisations

What's New?

With the previous hybrid models not being very effective in sales for reasons such as the price quotient and the unappealing exterior styling, Acura has aimed for a price cut of $4,050 model along with a redesign on the outside and a simplified package structure - to boost its popularity.

Expert Review

CARHP Editorial May 24, 2019

Powered by the same three motor system underpinning the japanese carmaker’s $156,000 NSX supercar - the RLX runs on a 6 cylinder 3.5L hybrid engine that incorporates both the elements of fuel and electricity to induce efficient, sporty and silent runs.

Thereby, taking its shot against the Infiniti Q70 hybrid, the Lexus GS 450H and the Mercedes GLE 350d, the japanese carmaker’s hybrid model along with its top of the line safety features has a lot to offer especially when Acura has put in a lot of effort to make the car more competitive in its segment.

2018 Acura RLX hybrid Sedan Engine

Engine and Transmission

While electron power is usually reserved for more efficiency focused cars (the Sport Hybrid is still efficient too), the RLX Sport Hybrid cleverly uses three motors to boost the performance-Thecarconnection.com

The hybrid powertrain from under the hood is familiar from the MDX sport hybrid. Acura even hopes that the similarities to the hybrid setup in the NSX supercar will be noticeable by the general audience. Even though there are a few shared parts, the 2 cars are very different.

Regardless, the RLX mates a 310 horsepower, 3.5L V6 engine with a 47-hp electric motor and seven speed dual clutch transmission up front. Then, in the back, one would find 2 more electric motors each contributing an extra 36 horsepower to provide torque vectoring all wheel drive. In total, the car will provide you with 377 horsepower when all the engines work together.

This hybrid setup delivers swift, slick power. The low-speed assist from the electric motors smooths out any clunkiness which is sometimes associated with dual clutch gearboxes. There's plentiful torque for passing when all 3 motors are working making the engine trumpet sonorously while doing so .

Speaking of rivals, the Acura RLX hybrid sport has eliminated the competition with its rivals. With almost similar engine sizes, all 4 cars are offering almost different horsepower and torque respectively wherein in the Acura RLX hybrid sport brushes past all 3 cars with that extra horsepower coming from the 3 motors. It's also worth mentioning that the RLX hybrid sport redlines at higher revs than all 3 cars.


With one of the most powerful motors in the segment at its disposal, the RLX hybrid sport turns out to be a quite, competent gem. It accelerates predictably quiet and stunningly fast. It turns out to be the fastest cars in the segment, taking flat 5 seconds to reach the 0-60 feat, whilst demolishing the quarter mile in an astonishing 13.5 seconds. THese numbers are quite impeccable for a luxury sedan in this segment.

All 3 cars being one of the best in their segment are competing head to head in a fierce rivalry with one just edging past the other with the smallest of margins. The RLX hybrid sport manages to be the fastest accelerating amongst the competition just brushing past the Infiniti Q70, both in the 0-60 and quarter mile time stamps.

Braking and Handling

While driving eagerly on twisted roads, the car always feels like a beat behind one's inputs. It just takes a split second too long for power to come back when one dips into the throttle. The RLX hybrid handles well and manages to maintain its composure during most of the situations it has to face courtesy of the super handling AWD setup.

In those everyday situations, the RLX Hybrid drives quitely and accelerates smooth enough making little to no wind noise entering the cabin while the stable chassis glides above the road imperfections with utter ease. Even though the steering feel is lacking wherein the connection between the 3 spoke steering wheel and the front tires is a little imprecise, but that's not what the car is about. Perhaps, the most effective thing is the easy-to-modulate brake pedal, which avoids none of the tell-tale, long travel signs of a hybrid vehicle like this.

2018 Acura RLX hybrid Sedan Fuel Economy

One of the main main trump cards that come in for the RLX hybrid is its efficient fuel consumption when compared to its gas powered sibling. All credit goes to the hybrid motor as a combined 28mpg figure is a drastic improvement over the standard RLX.

The RLX hybrid sport turns out to be not as fuel efficient as its rivals when the city, highway and combined MPG figures are calculated. Despite all its efforts, the acura falls short of its MPG figures when compared to rivals.

2018 Acura RLX hybrid Sedan Interior

Layout and Comfort

Inside, the RLX's interior similarly lacks passion and enthusiasm -Thecarconnection.com

Inside the car, there is a new color which Acura calls as ESPRESSO, bringing the total count to 4. Talking about technology, new to the Acura lineup is the RLX's traffic jam assist feature, which combines adaptive cruise control and lane keep assist to minimise driver input below 45mph.

The RLX seats five individuals on leather upholstery, indulging front travelers on heated seats that have 12-way power adjustments. The front seats are agreeable in their own particular right, yet excessively leveled. An absence of side support may create some uneasiness on long outings.

The RLX's interior is pleasant, at the same time it is functional enough for you to house in all your needs in the car; though there isn't much of a wow factor. The top infotainment display has a lower resolution than the bottom touchscreen, and the controls look dated and lack an intuitive flow. Rivals come with better interiors at this price.

Interior features

Some of the Highlights of the Interiors include:

  • Leather upholstery
  • Proximity key
  • Heated 12-way power seats up front
  • Collision mitigation braking system
  • Forward collision warning System
  • Lane-departure warning system active lane control
  • Blind-spot monitors
  • Rear-traffic monitoring system
  • Navigation
  • Voice-command recognition
  • 14-speaker audio system
  • Keyless Start
  • Adjustable Steering Wheel
  • Adaptive Cruise Control
  • Heated Mirrors

Cargo volume

The trunk gains close to an extra cubic foot of volume, thanks to a smaller, lighter battery pack - The Acura RLX Hybrid can pack in a lot of stuff inside its Cargo Area. The RLX's glove box and entryway pockets are modestly sized, which leaves the three-way-access to armrest compartment as the most usable space. The rear center armrest has slide-out cup holders.

Design and Dimensions

Inoffensive, but forgettable, the Acura RLX does little to stand out in its class- thecarconnection.com

The styling of the RLX was one major issue which was addressed, making Acura take necessary design changes to improve the styling and the all over appeal of the car.

The RLX's deeply sculpted hood now houses an attractive angular bulge over each front tire, part of the reshaping that also visits the car's nose, side sills, and rear end for 2018. The RLX's headlamps are restyled and now are more attractive, as is Acura's pentagon shaped grille, which replaces the chrome beak the RLX has won since 2013.

Given the competition, the RLX hybrid sport is not the lightest but the longest car in its segment. No doubt there is a tough competition in this segment and if rated then Acura RLX finds its place somewhere in the middle of the list. If we were to crib about a certain point of the Acura, it has to be about it's Ground Clearance as it is way to low for a sedan of this class.

Acura RLX hybrid sport vs Infiniti Q70 Hybrid LUXE 4dr

When it comes to comparing between the two, both the cars offer supreme build quality along with the best options for buyers in this segment. Both the cars are quite similar when it comes to their specs and features. But one thing that differentiates the Acura from the Infinity is the presence of 3 high output motors in the hybrid powertrain and a slightly well versed infotainment and safety package along with a refreshed and appealing exterior design, we have to set our preference to the Acura.

Acura RLX hybrid sport vs Lexus GS 450H 4dr

When compared with the Acura, Lexus shows better acceleration but it can be neglected as the difference is not much. Despite a bit lesser head room Acura RLX has the upper hand on Lexus in terms of front and rear shoulder as well as leg room. Lagging behind in ground clearance, the Acura RLX races ahead of Lexus GS 450 when the dimensions are compared. Acura RLX is certainly bigger in size and more spacious and comfortable too. Moreover, its better fuel economy gives it an edge over its competitors. Acura RLX comes with a driver friendly infotainment system whereas entertainment and a navigation system is hard to use in Lexus GS 450.
