The RL is powered by a 300-hp 3.7-liter V6 engine, paired to a five-speed automatic transmission with SportShift manual mode and paddle shifters. Acura's exclusive Super-Handling All-Wheel Drive (SH-AWD) system enhances grip, stability and all-weather control, while an electric power assist steering system provides direct feedback. Every RL is outfitted with 18-inch alloy wheels, Xenon High-Intensity Discharge (HID) headlights and a power moonroof; interior comforts include heated front seats, leather upholstery, automatic climate control, satellite radio, HandsFreeLink (Bluetooth) wireless connectivity, Bluetooth wireless audio streaming and a USB port. The available Technology package adds heated/ventilated front seats, an Active Front Lighting System (AFS), and a voice-activated navigation system with integrated rearview camera parking assist and real-time traffic and weather information. Additional available high-tech equipment includes Adaptive Cruise Control (ACC) and a Collision Mitigation Braking System (CMBS). Standard safety features include four-wheel anti-lock disc brakes with brake assist, Vehicle Stability Assist (VSA) with traction control, front side-impact airbags, overhead curtain airbags, active front head restraints and a tire pressure monitoring system. Following an extensive redesign last year, the Acura RL carries over unchanged for 2010.
