Frequently Asked Questions

Find answers to common questions about torque specifications

Q1

What are the main differences between the available engine options?

The 2014-2020 Acura RLX offers two engine options: a 3.5L V6 engine producing 310 hp and 272 lb-ft of torque, and a hybrid Sport Hybrid SH-AWD system combining a 3.5L V6 with three electric motors, delivering a combined 377 hp. The hybrid system provides enhanced performance and efficiency, with improved torque vectoring for better handling.

Q2

What transmission options are available?

The RLX comes with a 6-speed automatic transmission for the standard 3.5L V6 engine, while the Sport Hybrid SH-AWD model uses a 7-speed dual-clutch automatic transmission with integrated electric motors for seamless power delivery and improved efficiency.

Q3

What are the key safety features?

Standard safety features include AcuraWatch� suite (adaptive cruise control, collision mitigation braking, lane keeping assist, and road departure mitigation), multi-angle rearview camera, and advanced airbag system. Optional features include blind spot monitoring, rear cross-traffic alert, and parking sensors.

Q4

How does the fuel economy compare to competitors?

The 3.5L V6 model achieves 20 mpg city / 31 mpg highway, while the Sport Hybrid SH-AWD model delivers 28 mpg city / 32 mpg highway. These figures are competitive with luxury sedans like the Lexus ES and BMW 5 Series from the same era.

Q5

What are the recommended maintenance intervals?

Acura recommends oil changes every 7,500 miles or 12 months, tire rotations every 7,500 miles, and brake fluid replacement every 3 years. Regular inspections of the hybrid system and battery are also advised for the Sport Hybrid SH-AWD model.

Standard features include leather upholstery, heated front seats, dual-zone climate control, and a premium audio system. Available options include a Krell audio system, heated rear seats, adaptive suspension, and a rear entertainment system.

Q7

How does the cargo and passenger space compare to competitors?

The RLX offers 15.1 cubic feet of trunk space and a spacious cabin with 42.1 inches of front legroom and 38.8 inches of rear legroom. This is comparable to the Lexus ES and slightly larger than the BMW 5 Series in terms of rear passenger comfort.

Q8

What are the towing and payload capacities?

The RLX is not rated for towing. Its payload capacity is approximately 850 lbs, which is typical for a luxury sedan in its class.
