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 considering Vezel-based compact crossover

There's a distinct benefit to automakers having their own premium brand. After all, why develop one vehicle to be sold under one nameplate if you can turn it into two? Especially if a little reconfiguration and some premium accoutrements allow said automaker to charge significantly more for the luxury version. It's a winning formula - for crossovers especially - that Toyota has used to turn the Highlander into the Lexus RX (even if the first-gen RX arrived before the original Highlander), that Ford has used to transform the Edgee into the Lincoln MKX and that General Motors has applied to the Chevrolet Suburban to turn it into the Cadillac Escalade (to name just a few of the many examples out there). And it's one to which Honda and its Acura division are certainly not unaccustomed.
Acura has adapted its Euro-spec Honda Accord into the TSX, the Civic into the ILX, the CR-V into the RDX and the Pilot into the MDX. And now that the Honda Vezel is coming to market, Acura reportedly has its eye on that as well. The idea was first introduced when Acura unveiled the SUV-X concept (shown above) at the Shanghai Motor Show this past April, just a few months after Honda revealed its Urban SUV concept that previewed the production Vezel. At the time, says Automotive News, Acura said it intended to put the concept into production in China for the Chinese market, and it's reportedly moving ahead with those plans. But now that it is, executives are wondering where else they might find buyers for the premium compact crossover.
With the Vezel soon to begin production alongside the Fit at Honda's new plant in Mexico, it wouldn't be a stretch to see the Acura version follow suit. The market does, after all, seem to be heating up with entries like the Audi Q3, BMW X1 and Mercedes-Benz GLA, and we couldn't blame Honda - pardon us, Acura - for wanting a slice of that pie.

Watch two Acura NSXs scorch the Nurburgring

Some intrepid spy shooter captured these two Acura NSXs blasting around the Nurburgring. Without being there in person with a decibel meter, it's hard to tell if they're necessarily louder than stock cars, but they sure seem quick. Why test the cars now, when they've been on sale for a while now? Rumors are swirling that this could be a hardcore variant. It's unclear if Honda would call it a Type R, but a midlife refresh with a bit more power or a special limited edition with some extra kick wouldn't be unprecedented. The original NSX had several such models, and recent sports cars like the S2000 had low-volume editions, like the Club Racer variant in the United States and the Type S in Japan. Watch the video and draw your own conclusions about what this is or isn't. One thing's for sure: It's not a pure-EV variant. In other things recent about the NSX, we learned last month that an NSX GT3 non-hybrid race car version will go on sale soon. And here's our first drive of the US Acura-badged NSX from back in 2015. And here's another video from inside the cockpit during an open track day back in June.
