Acura refreshed the current RDX during this year Chicago Motor Show. The car was introduced today, in the first day of Windy City auto event. The 2015 Acura RDX gets many updates that will be available starting with this spring. 
To have an increased appeal and to show a refreshed face, the new Acura RDX features restyled front and rear fascia, Acura’s signature Jewel Eye LED headlights and LED tail lights with light-pipe design on all models and a new three-dimensional grille treatment. The lower front and rear fascia areas also support the new look, while all models receive new wheel designs.
Inside, the new RDX gets a fresh look with a high-contrast silver and black trim plus, standard heated front seats and new second-row air-conditioning vents, 8-way adjustable power passenger’s front seat, Acura’s intuitive dual-screen On-Demand Multi-Information Display, HD Radio, blind spot information (BSI) and Rear Cross Traffic Monitor.
Under the bonnet, we have the new 3.5-liter SOHC i-VTEC V-6 engine with Variable Cylinder Management cylinder deactivation technology. Peak horsepower and torque output are up: 279 (+6 hp) and 252 lb.-ft. (+1 lb.-ft.), respectively. Additionally, the RDX’s all-wheel-drive system – AWD with Intelligent Control system – has been tuned for greater rear torque bias.
