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.

Honda updates Takata airbag recall status for some models

The net enveloping vehicles in the Takata airbag inflator recall just seems to keep widening. Honda is now updating its previous campaign to revise the status for even more models that were ever registered in (or originally sold in) 13 high-humidity US states and territories.
All of these vehicles were included in the company's earlier repairs. However, at the time this fix was titled "a safety improvement campaign." This latest action upgrades that condition to "a formal recall," according to Honda's official statement. The models include: the 2003-2005 Honda Accord, 2001-2005 Civic (pictured above), 2002-2005 CR-V, 2003-2004 Element, 2002-2004 Odyssey, 2003-2005 Pilot, 2006 Ridgeline, 2003-2005 Acura MDX and the 2005 Acura RL. All of these need to have their passenger-side, front airbag inflator replaced, and the recall affects Alabama, Florida, Georgia, Hawaii, Louisiana, Mississippi, South Carolina, Texas, Puerto Rico, the US Virgin Islands, Saipan, Guam and American Samoa.
As with the rest of these affected vehicles, it's possible in a collision for the inflator to rupture spraying metal shrapnel at occupants. There are at least 139 injuries attributed to this problem from a variety of automakers so far. Among this latest population of vehicles, Honda says there have been no confirmed injuries or fatalities related to these exploding inflators.

Honda Expands Takata Airbag Recall To 5.4M Units In The US

While Honda already announced plans to take its front driver's side Takata airbag inflator recall nationwide, the automaker has now officially reported on the number of affected vehicles and the specific models in need of repair. The expanded campaign covers an estimated 5.4 million units across the US, including those already being fixed under the previous regional actions. That number is an expansion of the five million units initially reported by NHTSA. The affected models under the nationwide recall are the 2001-2007 Accord with a four-cylinder engine, 2001-2002 Accord V6, 2001-2005 Civic, 2002-2006 CR-V, 2003-2011 Element, 2002-2004 Odyssey, 2003-2007 Pilot, 2006 Ridegline, 2003-2006 Acura MDX, 2002-2003 TL and 2002 CL. For customers who expressed concern about their vehicle's safety, Honda had already been replacing the inflators nationwide. It's possible for the inflators in these vehicles to rupture when inflating the airbag, spraying metal fragments at occupants. This problem has been blamed for at least five deaths worldwide and at least 139 reported injuries. In its statement, Honda said that it worked with Takata to test the recalled inflators in the original high-humidity recall regions, and there were no abnormal deployments in these evaluations. Honda will begin notifying owners by "over time," according to its statement. Priority will be put on the geographic areas with the highest risk of ruptures. Those in the original recall region were contacted in September. Earlier in December, Honda partnered with Autoliv to supply the automaker with replacement inflators for this campaign. Autoliv predicted it would take six months for deliveries to start. Takata also increased its production of substitute components.

Statement by American Honda Regarding National Safety Improvement Campaign: Driver's Front Airbag Inflator Supplied by Takata Dec 8, 2014 - TORRANCE, Calif. Honda will voluntarily expand a regional Safety Improvement Campaign initiated in June 2014 (NHTSA No. 14V-351) into a national Safety Improvement Campaign affecting certain 2001 through 2011 Honda and Acura vehicles in the United States to replace the driver frontal airbag inflator, free of charge. Honda is expanding this Safety Improvement Campaign to address concerns raised by its customers whose vehicles were not included in the regional campaign.
