Acura announced the all-new 2014 RLX is the most powerful, spacious, and technologically advanced sedan introduced by the luxury brand. Powered by an all-new 310-horsepower direct-injected V-6 engine, and featuring an array of Acura signature technologies, including Precision All-Wheel Steer™, Jewel Eye™ LED headlights, and the next generation of the AcuraLink® connected car system, the Acura RLX delivers new levels of technology-enhanced performance, comfort and convenience in Acura's flagship sedan.
Using smart packaging, advanced aerodynamics, and lightweight body design, along with fuel-saving i-VTEC with Variable Cylinder Management engine technology, the Acura RLX delivers the most spacious five-passenger seating in its class along with a top-class EPA fuel economy rating of 20/31/24 mpg (city/highway/combined).
With a longer wheelbase and wider greenhouse than competing mid-luxury sedans, the new RLX delivers full-size interior space in a nimbler, mid-size luxury sedan package. The Acura RLX boasts the longest rear-seat legroom (38.8 inches), and best front (59.6 inches) and rear (57.0 inches) shoulder room in the mid-luxury class. The RLX advanced body design makes extensive use of high-strength steel and aluminum, further aiding its outstanding fuel efficiency, straight-line performance, and superior handling agility.
The new Acura RLX reaches higher and farther into the high-end luxury sedan market with an incredible array of advanced safety, driver-assistive, and information and media technologies, including the standard next-generation AcuraLink™ connected car system, and Multi-Angle Rearview Camera; along with available Lane Keeping Assist System (LKAS), Adaptive Cruise Control with Low-Speed Follow and Blind Spot Information (BSI) system. Safety systems available on the RLX include technologies such as Collision Mitigation Brake System (CMBS), Forward Collision Warning (FCW) and Lane Departure Warning (LDW).
Utilizing Acura's next-generation Advanced Compatibility Engineering™ II (ACE™ II) body structure, along with seven airbags (including new driver's knee airbag), the Acura RLX is anticipated to earn top-level safety ratings - a 5-star NCAP Overall Vehicle Score, and IIHS "TOP SAFETY PICK+" rating, including a GOOD rating in the IIHS small overlap frontal collision test.
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 2014 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.
Static and dynamic rigidity and rear lateral stiffness are significantly improved. To increase stiffness and rigidity in key areas without increasing weight, 55 percent of the RLX body in white is made from high-strength steel. Hot-stamped high-strength steel is used in key areas for enhanced safety collision performance, with the added benefit of anticipated high scores in narrow offset, side impact, and roof strength tests. Extensive use of aluminum body components in key areas saves 76.1 pounds compared to traditional all-steel construction.
The 2014 Acura RLX features the world's first Jewel Eye™ LED headlights, which offer outstanding light distribution and excellent down-the-road illumination performance and light characteristics. The RLX taillights utilize periphery LED illumination that is both effective and highly distinctive.
