The 2007 Acura RDX has paddle shifters, which can be used while in “D” mode for a quick shift, or the sportier “S” gearing. Drivers can use “S” without the paddles, for quicker automatic shift points, or can go into manual mode by using the paddle shifters. The Acura RDX and the RL also share another common trait: SH-AWD. Acura’s successful all-wheel-drive system distributes up to 100 percent of the available torque to the outside rear wheels, based on road conditions, cornering speed and acceleration.
