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.

2016 Acura RDX Review [w/video]

Acura is deeply confused as a brand. Is it sporty or luxurious? Conservative or avant garde? Truly premium, or just premium for Honda? At its heart, there is a simple truth: despite confused characters, Acura vehicles are usually very competent. The new TLX, for example, is a smart, comfortable, near-premium sedan. The new ILX, meanwhile, is a huge improvement over its predecessor, and finally feels like the entry-level, premium four-door stepping stone Acura needs. Then there's the RDX. Placed in a very hot segment, the Honda CR-V-based crossover never quite caught on. For its first six years on the market, it couldn't even break 25,000 annual sales. The more mainstream redesign in 2013 made some waves, nearly doubling sales, but Acura still fell way behind the competition. In 2014, the Lexus RX outsold the RDX nearly three to one. For 2016, the RDX gets a substantial refresh. The biggest visual update comes from Acura's polarizing, JewelEye LED headlights, which are standard. These aren't the best looking headlights on the market, but the many 'eyes' are better executed on the RDX than any other Acura. The LED daytime running lights round out a nice face during light hours, too. More subtle tweaks are given to the bumpers, with larger intakes in front and bigger reflector housings around back. The seats are broad, flat, and comfortable. The big change in the cabin cannot, sadly, be called an improvement. It's the addition of the Honda/Acura dual-screen system, and while it gives the interior a techy vibe, the user experience is convoluted and unintuitive. The rest of the cabin's design, however, is easy to like. Material quality is adequate for the segment. Plastics are abundant, but are soft to the touch, while fit is impressive and typically Honda throughout. The steering wheel is a parts shelf item and feels just a bit too large for a crossover of this size. The seats are broad, flat, and comfortable, and backseat passengers are treated quite well. Even with the driver's seat set for your six-foot, one-inch author, there's plenty of space in back, especially for long-legged folks. Small changes are found under the RDX's hood, where the 3.5-liter i-VTEC V6 gains six horsepower and one pound-foot of torque.

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.
