2014 Acura MDX shows up exactly as expected

Acura (and parent company Honda, for that matter) doesn't always leave a lot to be left to the imagination when they unveil prototypes at auto shows. Case in point: Take a gander at the Acura MDX Prototype that debuted at the Detroit Auto Show this past January, and then look at the production-spec 2014 MDX pictured above. See what we mean?
Design-wise, there frankly isn't a whole lot to get excited about with this MDX. Sure, a lot of the chiseled, sharp lines from the previous-generation model have been smoothed out in favor of something that will likely have more mass-market appeal, but to our eyes, the MDX has simply lost a lot of its visual flair in the process. To quote Autoblog senior editor Seyth Miersma, this new one just looks like the old one after melting by 10 percent. The end result is something that more closely resembles the company's smaller RDX crossover than anything else, with other subtle design elements mimicking what we've seen on the ILX and RLX sedans. It's all fine, but again, not exciting. The good news, however, is that thanks to the use of new lightweight materials, the 2014 MDX is 275 pounds lighter than the outgoing model.
Updates to what's underneath the MDX's new skin are hardly surprising, but still welcome. Power comes from a direct-injected 3.5-liter V6 making 290 horsepower and 267 pound-feet of torque, mated to a six-speed automatic transmission with both front-wheel drive and Acura's Super-Handling All-Wheel Drive on offer. Acura estimates that front-drive models will achieve 20/28/23 miles per gallon (city/highway/combined), and says that adding the SH-AWD drops those numbers to 18/27/21. Acura will offer a new Integrated Dynamic System that allows the driver to choose between normal, sport and comfort settings, and the new MDX will ride on a choice of either 18- or 19-inch alloy wheels.

A smoother operator | 2017 Acura MDX Sport Hybrid First Drive

There's a lot to unpack when trying to understand the 2017 Acura MDX Sport Hybrid. Acura is billing it as a three-row crossover infused with NSX technology via a sport-oriented hybrid drivetrain. So it's a hybrid crossover, sure. But it doesn't comport itself like a traditional crossover, nor is it a conventional hybrid. What it is, underneath, is an intentionally subtle blend of impressive technologies doing their best to appear transparent – and it's too subtle, I fear, to be appreciated by those who'd like it the most. This is a lot of foreshadowing, but if you're not familiar with the MDX Sport Hybrid's powertrain, let's fill you in. The MDX Sport Hybrid uses the same basic system as the 2014 RLX Sport Hybrid, with some newer NSX battery tech sprinkled in, packaged neatly into the refreshed third-generation MDX platform. The system improves handling and efficiency – but more important, it smoothes out the harshness of shifts and engine stop-starts. We do need to examine the system in some detail to understand how all this affects the MDX as a whole, so let's go toe to tail. Up front is a transversely-mounted 3.0-liter V6 making 257 horsepower and 218 pound-feet of torque, as well as featuring i-VTEC and cylinder deactivation. It's slightly smaller than the 3.5-liter V6 found in the conventional MDX and many other Honda and Acura products. Attached alongside is a Honda-produced 7-speed dual-clutch transmission that has a 47 hp, 109 lb-ft electric motor-generator stuffed inside. Amidships are the battery pack and the electronics to control it, and stretching aft from there are large cables feeding power to a pair of electric motors that reside in single housing, one for each wheel. Together, they produce electron witchcraft and torque-delivery wizardry – and add 72 hp and 108 lb-ft of torque to the mix. The total system output is 321 hp and 289 lb-ft of torque – a gain of 31 hp and 22 lb-ft over the conventional MDX SH-AWD. Beyond the raw numbers, there's the remarkable subjective benefit of the Sport Hybrid's drivetrain. Engine start-stop events are quiet and smooth, nearly imperceptible when under way – in stark contrast to the too-perceptible shudder of competing engines kicking on. The electric motors (mainly the one residing in the transmission) add in power to make up for the lull during a shift, making shifts up or down seamless, as well as providing regenerative capacity.

NHTSA gives okay for three automakers to skirt tire-related recalls

BMW, Honda, and Mercedes-Benz are all going to avoid small recalls, after the National Highway Traffic Safety Administration issued petitions for "findings of inconsequential noncompliance" to the three manufacturers, according to Tire Business. Basically, the petitions allow the brands to avoid recalls for some very, very minor issues.
BMW had tire placards on 364 X6 M CUVs that stated the car could only handle four passengers, when in reality it had room for three in the back. Actual plausibility of fitting three real humans in the slope-roofed Bimmer aside, the Munich-based manufacturer argued it was inconsequential, as the placards were correct regardless of the number of passengers.
Honda's case focused on 212 2011 and 2012 Acura TSX sedans equipped with 18-inch wheels. The TPMS systems on these cars were set for 17-inch wheels, rather than the larger hoops, but even with the lower settings, the tires maintain adequate load capacity.
