The 2014 Acura RLX is larger than the previous RL model in several key exterior dimensions, including width, wheelbase, and front and rear track. The wheelbase, at 112.2 inches, is two inches longer than the previous RL model, providing more rear passenger room and improving the ride quality in the process. At 74.4 inches wide, the Acura RLX is also a substantial 1.7 inches wider than the previous RL model.
The 2014 Acura RLX interior is an all-new design that combines welcoming five-passenger comfort with by far the most luxury and technology ever offered in an Acura. High-end premium elements like a carefully stitched leather instrument panel cover, soft-touch materials, premium finishes and rich wood-grain accents combine with an intuitive new control layout to create a distinctive environment in tune with this luxury performance sedan’s clearly defined sporting character.
The 2014 RLX is powered by an all-new 3.5-liter Direct Injection SOHC i-VTEC® V-6 engine matched to a Sequential SportShift 6-speed automatic with paddle shifters. This is the first Acura production car to feature “Earth Dreams Technology,” which is comprised of a next-generation set of technological advancements to the engine, which greatly enhance both driving performance and fuel efficiency.
Rated at 310 horsepower and 272 lb.-ft. of torque (SAE net), the V-6 powerplant in the Acura RLX develops an additional 10 horsepower and 1 lb.-ft. of torque compared to the 3.7-liter engine equipped in the RL. For exceptional drivability, the RLX’s new 3.5-liter engine produces in excess of 90 percent of its peak torque over a very broad range of engine speeds, from 2,000 rpm to 6,600 rpm.
In spite of the peak horsepower increase, the new engine has impressive EPA- fuel economy ratings for a luxury sedan, with ratings of 20 mpg in the city and 31 mpg on the highway. The 3.5-liter engine meets the stringent ULEV-2 California Air Resources Board (CARB) emissions rating.
The Acura RLX and RLX with Navigation grades feature 7-spoke 18x8J noise-reducing alloy wheels while the Technology, Krell Audio and Advance grades feature larger 19x8J noise-reducing alloy wheels. The special noise-reducing design lowers tire noise by 7-decibels across the audible frequency range.
