( http://www.TFLcar.com ) The 2013 Acura RDX is all new and ready to take on the competition like the Audi Q5 and the BMW X3. Gone is the old four banger turbo charged engine now replaced with a new 273 HP six cylinder.  The new 2013 RDX is also a little bigger and much more grown up than the old car it replaces with more luxury, more performance and more refinement...all that costs more... about $1500 more.
