The new V-6 engine and 6-speed transmission team to deliver an EPA estimated* city/highway/combined fuel economy of 20/28/23 mpg (front wheel drive) and 19/27/22 mpg (all wheel drive). In the case of the all wheel drive model, this represents a 5 mpg increase in highway fuel economy versus the previous RDX. As expected, the 2013 RDX complies with EPA TIER 2 – BIN 5 and CARB LEV II ULEV emissions standards.
The 2013 RDX also features a new all-wheel-drive system that is smaller and lighter than the previous drivetrain setup. Known as AWD with Intelligent Control, the new system also is more efficient than the prior version, which, along with the reduced weight, helps achieve the AWD RDX's increased fuel economy.
