From Acura press: The Acura 3.5RL is the flagship sedan of the Acura lineup. The product of an intensive research and development effort in which every nuance of the interface between driver and car was examined, the 3.5RL luxury sedan takes Acura to a new level of comfort, refinement and human engineering. At the same time, the 3.5RL delivers an engaging driving experience with the confident handling, immediate response, advanced safety engineering and high levels of performance Acura drivers have come to expect.
Dramatic improvements in comfort,ergonomics, noise, vibration and harshness performance make it the quietest, smoothest, most refined Acura ever built. The 3.5RL is a world-class luxury sedan,competing with the likes of Mercedes E Class, BMW 5- series, Audi A6, Lexus GS 300/400 and LS 400, and the Infiniti Q45.
The 3.5RL is Powered by the largest engine with the most torque ever produced in an Acura sedan. The 3.5-liter V-6 engine develops its peak torque at an extraordinarily low 2800 rpm, giving immediate throttle response, authoritative acceleration and the on demand power typical of a big-boreV-8, but with the light weight and packaging efficiency of a V-6.
The 3.5RL is powered by a 3.5-liter, all-aluminum,single-overhead camshaft, 90-degree V-6 engine that produces 210 horsepower at 5200 rpm and 224lb ft of torque at a very low 2800 rpm that is signed to go 100,000 miles before its first scheduled tune-up. Four valves per cylinder and a three-stage variable induction system help to provide both high torque at lower engine speeds and excellent breathing at higher engine speeds. The 3.5RL engine was developed with two major goals in mind: first, to provide maximum power at the engine speeds used in most day-to-day driving (1500 rpm to 4000 rpm). And second, to be both quieter and smoother than any engine in Acura history.
The engine is located longitudinally moving weight to the rear of the car for the 60/40 weight distribution deemed optimum for a front-wheel-drive sedan. The longitudinal mounting also yields benefits in Noise, Vibration and Harshness (NVH) performance, because it allows the use of softer and better located engine and transmission mounts.
An electronically controlled four-speed automatic transmission,with Grade Logic Control software, is standard on every 3.5RL.
