Acura RDX

For 2007, a completely new Sport Utility Vehicle joins the growing Acura product line. The RDX is an advanced 5-passenger Entry Premium SUV with handling and performance that positions it as the SUV soul mate of the Acura TSX sports sedan.

The RDX concept was initiated in California and then developed in Japan. It features precedent-setting engineering features for Acura, including the luxury division's first turbocharged and intercooled engine, the first adaptation of the Super Handling All-Wheel Drive™ (SH-AWD™) system to an SUV, and Acura's first standard 18-inch wheels and tires. Likewise, the RDX continues Acura's "Safety Through Innovation" with the application of cutting edge standard safety technologies. True to form for Acura, the RDX also offers a class-leading array of sophisticated electronic technologies that are seamlessly integrated to keep its passengers informed, in touch and entertained.

Acura's new RDX shares much in concept with the TSX. Though one is an SUV and the other is a sports sedan, both vehicles are designed to blend strong performance with agility and precise handling. Excellent fuel economy and low emissions are also top priorities. The unique positioning of this new Entry Premium SUV within the Acura product line guided the development of a special powertrain for the RDX. A conventional 4-cylinder engine would have lacked the horsepower and torque needed to make the RDX a strong performer. On the other hand, a 6-cylinder would add weight and have higher fuel consumption.

A perfect solution came in the form of a turbocharger - a first for an Acura production vehicle. The RDX has an innovative new variable flow turbo that overcomes the shortcomings of conventional turbo designs and delivers an unusually broad powerband with little or no lag in throttle response. In addition, Acura's turbo design provides this benefit with high reliability. This is because airflow is controlled before it enters the turbocharger, rather than within the turbocharger as in traditional variable-flow designs. Acura's variable flow turbo design thus eliminates moving components that work directly in the stream of hot exhaust gases.
