Mudfest 2013: Tom's Hardware Helps Test 23 SUVs

Acura RDX

Acura’s RDX is completely new for 2013, and it competes in the compact luxury class against a pair of European crossovers. Underpinning the RDX is the same platform at the heart of Honda's CRV. But that's not necessary a bad thing. The RDX trades last year's turbocharged 2.3-liter motor and advanced Super-Handling AWD (SH-AWD) for Honda’s corporate 3.5-liter V6 and Real Time AWD system, again, lifted from the CRV.

The V6 motor features Honda’s latest Earth Dreams technology that improves efficiency by adding direct injection and other tweaks. A six-speed automatic transmission sends power to all four wheels.

Acura renames the Honda Real Time AWD system to All-Wheel Drive with Intelligent Control, but it operates the same. This technology remains front-biased, with 100 percent of power sent to the front wheels during cruising, which allows it to be just as fuel-efficient as standard front-wheel drive vehicles. However, the system has a neat trick: during acceleration or when the wheels slip in dry conditions, it sends 25 percent of the power to the rear wheels to help out. It can also split power 50:50 when slippage occurs on wet surfaces.

While the RDX’s AWD system works the way Acura says it should, its front-wheel drive roots became apparent when we pushed the car around pavement and dirt. This thing still behaves very much like a FWD vehicle, and it understeers noticeably before the rear wheels kick in. I probably pushed the RDX harder than most buyers will, but that's something to think about nevertheless.

The RDX's powertrain is very smooth. Its V6 has enough power to embarrass what were considered sports cars 20 years ago from a stop. The driving dynamics are good, and you get great throttle and steering response. While the RDX isn't as sporty as Mazda's CX5, it's still a pleasure to drive. Steering felt a little light, but it wasn't disengaging by any means.

Our sample came with the Tech Package, which adds the Acura Navigation System, AcuraLink Communication System, integrated hard drive, GPS-linked climate control, and other niceties. The eight-inch navigation display sits high and center on the dash, presenting crisp text and graphics. There are plenty of physical buttons to control standard system functions. Acura employs a knob mounted on the center stack to control the navigation system. Unfortunately, most of its functions are disabled when the vehicle is moving, and they only work with not-so-good voice commands.

This struck us as odd, since we went hands-on with a 2008 Acura MDX that offered full functionality in any situation. So, we asked the Acura rep at Mudfest, and his response was reasonable. Basically, the company wanted to implement this before lawmakers made it mandatory. It's not a response we're happy with, but perhaps a necessary curb of distracted driving.

We didn't get a chance to hook up our iPad or pair the HTC Droid DNA. It was getting late by the time we had a crack at the RDX, and the folks at DirtFish were ready to kick us out.

Acura’s design language is smoother than what we've seen previously. The RDX is not very aggressive, but it still looks clean and bears simple lines. It was definitely built for the Acura demographic, and we find it stylish enough.

    Interesting but with so little time per vehicle, the results are obviously suspect. I believe the Wrangler is the best off-road vehicle, not sure about the rest. But that conclusion come from more in depth reviews which actually "review" the vehicle.

    Well, at least the Grand Cherokee can (literally) run (on) Crysis... but I wonder if it starts faster with an SSD?

    Anybody find it funny that the vehicle largely based on WWII era technology does the best in the offroad tests while the newer, high-tech "tall wagons with AWD" get stuck in more than a couple inches of snow? Just like tablets, phones, and laptops aren't going to make desktops go away, unit-body transverse-engine four-banger cars aren't going to replace body-on-frame trucks with solid axles and leaf springs when you need to do real work. The even funnier thing is that an "ancient" carbureted pushrod V8 and manual transmission would have made the Wrangler perform *better* in the offroad tests than the 8-speed slushbox and fancy twin-cam V6 car engine.

    Stopped reading when I saw the Toyota 4Runner wasn't in the mix.

    Its a great offroad vehicle for the price. The other two are capable vehicles, but the buyer demographic will never take them offroad.

    Mechanical technology has its uses but the WWII Era vehicles are awful for comfort and driving feel. Not going to lie though, the G-wagen is one sexy beast IMO. The Wrangler is only a 6-speed auto iirc, but there's a company that offers HEMI conversions :D.

    Toyota didn't submit any vehicles, disappointingly. Was hoping the 5th Gen 4Runner and new RAV4 would be there :(.

    Holy crap these are expensive vehicles, who is buying these monsters? I make $60k a year and live comfortably but there is no way I could afford any of these. The HYUNDAI clocked in at over $35k....The painfully anemic Subaru(with what has to be the worst manual I've ever used) is still over $20K and it's terrible, poor power, poor gas mileage, poor off road performance, ugly styling, shitty electronics, and only moderate interior room...but that's the only one in my price range? How poor am I exactly?

    Seriously the WRX transmission is quite nice, how the hell did all of their others end up to be so godawful?

    Guess I'm stuck with my 1999 Isuzu Rodeo until I can win the lottery...oil burning, gas guzzling eyesore it may be but hey the money I saved will buy me a decades worth of gas.

    Nothing wrong with an old Isuzu, before GM raped and pillaged them :(. Cars are so expensive nowadays, you're about as poor as I am, but add in two kids and a wife. The WRX has a nice manual because its a performance vehicle. Manuals in economy cars are usually sloppy. long throws and not very exciting, which is why I hate to say to get the auto in economy cars. But, the XV Crosstrek could probably be fixed with a short throw shifter, that usually does wonders.
