I have just taken an RDX for a test drive. The engine is very peppy once it gets into turbo zone. On the downside, the gas mileage is negatively affected by the AWD that cannot be switched off. Another necessary improvement deals with the cargo space (my current TL has a larger trunk). Also, the back seats do not fold down, so there is no way in which you can expand the cargo space (why call it an SUV then?). Overall, the new RDX is a fine car!
