A new term seems to have settled for vehicles like this: CUV. Crossover Utility Vehicle, not simply "crossover vehicle," which has been used for a while. Meaning, basically, an SUV with unibody construction, like a car: the chassis, floorpan and body are all one piece, which adds rigidity to the structure, saves weight and rides softer, but isn't as rugged as a body-on-frame vehicle, like a pickup truck or an SUV built on a pickup truck platform. Fine. But who can tell?
Acura calls the all-new 2007 RDX a CUV. Here's the irony: it earns the name because it's sportier than a Sport Utility Vehicle. Sporty driving is what this CUV-formerly-known-as-SUV is all about. The RDX most resembles the BMW X3, which BMW separates from the SUV crowd by calling an SAV: Sport Activity Vehicle. Got it?
What makes the RDX different is that it uses a turbocharged four-cylinder engine to make its hearty 240 horsepower, rather than Honda's smooth V6. Because the RDX is built on the small Honda CR-V platform, there wasn't room under its hood for the V6. This is the first turbocharged engine that Acura has produced. It's 2.3 liters, and comes out of the Acura TSX, with many changes making a completely different powerband.
Proving its commitment to sport, the RDX uses a sequential five-speed automatic transmission with paddle shifters, a firm independent suspension made for cornering, and Acura's patented SH-AWD (Super Handling All Wheel Drive) system, which delivers a higher proportion of power to the outside rear wheel under hard cornering, thus keeping the car on line.
But also proving a commitment to luxury, the RDX offers only leather, no cloth interior, and other standard luxury touches, such as a power moonroof and dual-zone climate control. That narrows the intended buyer down, to someone who doesn't want to compromise the cornering for a comfortable ride (the firm suspension), but isn't willing to sit on cloth seats. Also someone who doesn't care about dramatic or distinctive styling, because the RDX closely resembles the Honda CR-V. Women, who normally go for the Acura approach toward silky style with performance, will want to think twice about the niftiness of the RDX.
