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.

Acura organizes new business division to confront falling sedan sales

Honda and Acura North America have announced a major restructuring of operations in hopes of turning around Acura's flagging business. For 2013, sales for Acura's sedans dropped 10.4 percent, while its CUV sales grew by 21 percent. The newly formed Acura Business Planning Office will attempt to right the ship.
As part of the restructuring, Acura is promoting Erik Berkman from President of Honda R&D Americas to lead a new division called the Acura Business Planning Office. Berkman has been with Honda since 1982 and led development of the 2006 Accord. He was also the first US engineer to head North American research and development and has been head of Honda Performance Development since 2008. "Erik's appointment to the new Acura Business Planning Office is a clear indication of the high priority we place on Acura," said Honda spokesperson Jeffrey Smith to Automotive News.
American Honda Motor President and CEO Tetsuo Iwamura is also going to be working to improve the business. He has been elected chairman of American Honda's board, and has simultaneously taken the new position of Corporate Brand Officer to improve the management of the company's brands.

Honda integrating Siri into select models

Honda has partnered up with Apple to bring Siri to the Accord, Acura RDX and ILX. Owners who have an iPhone running iOS 6 will be able to ask the software to perform a number of tasks via voice command using the vehicle's on board microphone and speaker systems. What's more, the tech will put the iPhone into an "eyes free" mode, which turns the screen off to help reduce distraction while driving. Honda says it has reworked its Bluetooth and HandsFreeLink systems to accommodate the Siri functionality. While the tech will only be available on three of the company's models right now, we imagine it won't be long before it shows up elsewhere.
As you may recall, Chevrolet integrated Siri into its products with vehicles like the Spark and Sonic, but Mercedes-Benz and Chrysler have also toyed with the tech to varying degrees. The seamless voice command seems to be light years ahead of the tech manufacturers are currently playing with. Check out the full press release from Honda below for more information.
