The Acura RDX is Acura’s first compact luxury crossover SUV, taking over from the MDX as Acura's entry-level crossover SUV, as the MDX grew in size and price.
Originally previewed as the Acura RD-X concept car, the production RDX had its debut at the 2006 New York Auto Show and went on sale on August 11, 2006. A facelifted 2010 model went on sale in August 2009, adopting Acura's power plenum grille seen on its sedan models. Front-wheel drive was also added.
The first generation RDX is powered by turbocharged gasoline engines; at the time, this was uncommon among Honda vehicles although it has since become common. The 2.3-litre straight-4 K23A1 engine has all-aluminum construction, an i-VTEC head, and dual balance shafts. It is also one of the only four-cylinder powered luxury SUVs. Honda's variable flow turbocharger reduces turbo lag by using a valve to narrow the exhaust passage at low rpm, increasing the velocity of the exhaust flow and keeping the turbine spinning rapidly. At higher rpm, the valve opens to allow more exhaust flow for increased boost. The engine also features a top-mounted intercooler which receives air from the grille, channeled by ducting under the hood. The Acura RDX engine is rated at 240 bhp (179.0 kW; 243.3 PS) at 6000 rpm with a torque peak of 260 ft·lbf (350 N·m) at 4500 rpm. The U.S. Environmental Protection Agency (EPA) estimated fuel mileage is 19 mpg‑US (12 L/100 km; 23 mpg‑imp) city and 23 mpg‑US (10 L/100 km; 28 mpg‑imp) highway miles per gallon. Driving style and the terrain plays an important part in this Vehicle's fuel economy. Uphill driving, frequent lane changes and sudden accelerations can increase turbo usage to increase torque output to the SH-AWD system and thus cause much higher fuel consumption. New more recent EPA mileage estimates as of February 2007 are 17 mpg‑US (14 L/100 km; 20 mpg‑imp) city and 22 mpg‑US (11 L/100 km; 26 mpg‑imp) highway. The required fuel is premium 91 octane unleaded.
