My folks visited this weekend, and I spent some time with their new car. In a word, it's remarkable.
This is the first opportunity I've been able to spend a good amount of time with Acura's SH-AWD, and it simply transforms the vehicle. You can feel the difference right away. I turned the traction control off and played with it on some rural roads. If you come out of a corner at full throttle with a downshift to 1st or 2nd, you just KNOW the car should push off the road, but it doesn't. You can turn the wheel more and more and the car just STICKS. It doesn't understeer and doesn't oversteer. It just goes. Quite frankly, it was hard to believe how well it performed, even after driving it.
On the road, it's a total peach. Their loaner was a '12 model and they said that it really beat them up (ride was too firm for them). This '14 feels very nice, it really does. It's extremely quiet, the ride is comfortable, handling is good for being 4,300 pounds, and there's a TON of room inside. This engine is supposed to have VCM, but I didn't feel its intervening all weekend. Their AVG MPG since they bought it was 25.5 mpg, which is mostly the trip to North Carolina at 75 mph. Excellent mileage for the performance that it delivers. The 6-speed automatic is tuned great...it doesn't default to top gear as so many modern transmissions like to do...it seems to always be in the correct gear.
The adaptive cruise control and lane keep assist are really impressive. The ACC will obviously keep you at a safe distance from the vehicle ahead of you. The following distance you want to keep is user selectable with a button on the steering wheel. The following distance is relative, meaning that it will shrink and grow as that driver in front of you slows down and speeds up. If traffic comes to a stop, the Acura will stop, without driver intervention at all. But because the following distance is relative, it eases right up to the back of the car ahead, just as I would if I were controlling the brake. When traffic in front resumes, you press the "resume" button on the cruise control and the Acura will accelerate you, keeping the relative following distance you have set. It's really quite smartly done. The lane keep assist is kind of freaky. Yes, the car will steer you along. As long as it finds lane markers, it'll keep you in the lane, within reason. That's more of a novelty than a feature in my opinion. It's totally defeatable, and I thought it was fun to try, but I doubt that I'd ever use it. Dad agrees, saying that he really likes the adaptive cruise, but doesn't use the lane keep assist.
The new MDX is quite a package. For the price you pay for one, I guess it should be. I was totally blown away, however, by the SH-AWD. That system completely transforms a big and heavy FWD SUV into something it's not. It's very, very well done.
