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 to recall 1.1 million U.S. vehicles to re-replace Takata airbags

Honda said on Tuesday it would recall about 1.1 million Honda and Acura vehicles in the United States to re-replace defective Takata airbags on the driver's side. The company said it was aware of one injury linked to the defect that may have caused the airbag to rupture when it was deployed in a crash. The vehicles involved in the recall were previously repaired using specific Takata desiccated replacement inflators (PSDI-5D) or entire replacement airbag modules containing these inflators. "Those replacement inflators," Honda said in a statement, "are now deemed defective." Free repairs of the recalled cars would begin immediately in the United States with replacement parts made by alternate suppliers, Honda said. Honda became aware of the issue after a Honda Odyssey crash, where the front airbag deployed and injured the driver's arm. An investigation later showed that manufacturing issues at Takata's Mexico facility introduced excessive moisture into the inflator during assembly, leading to the problem. The total number of recalled inflators is now about 21 million in about 12.9 million Honda and Acura vehicles that have been subject to recall for replacing Takata front airbag inflators in the United States, the company said. Automakers in the United States repaired more than 7.2 million defective Takata air bag inflators in 2018, as companies have ramped up efforts to track down parts in need of replacement.
