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 ZDX getting the axe after 2013 despite new updates [w/poll]

The Acura ZDX hasn't exactly lived a conventional existence, so perhaps we shouldn't be surprised that its death announcement isn't going according to standard industry protocol, either. Parent company Honda has taken the unusual step of trumpeting a refreshed-for-2013 model while simultaneously announcing that this will be the model's last year. According to Acura, the model's cancellation comes as the brand "sharpens its focus on new models and core products" like the forthcoming RLX sedan.
The audaciously styled crossover has been, to be charitable, a very reluctant seller since its 2009 introduction, but for 2013, Acura is jazzing up its concept car for the street with new kit. The changes include a lightly reworked front shield grille along with new power folding side mirrors and new tech features including lane departure and forward collision warning systems.
We'd say that announcing the model's discontinuation at the same time one is presenting a freshened model could hurt sales, but we're not sure there's anyone paying attention. Last year, Acura managed to shift just 1,564 units of the ZDX, giving it the No. 4 spot on our Worst Sellers of 2011 list. Through September, Automotive News reports that only 642 examples have been sold in 2012, making it one of the rarest new cars on the market.

Honda CEO says we shouldn't expect any new sports cars

It wasn't so long ago that Honda was known for its sporty two-door models, with models ranging from the Civic del Sol to the Prelude and from the Acura Integra and RSX to the Honda S2000. But look at its range today and all you'll see are the Civic and Accord coupes. Honda has essentially let competitors like the Scion FR-S/Subaru BRZ and Nissan 370Z take the place it once claimed as its own. But if you were hoping Honda would fight back with a new coupe or convertible of its own, we're afraid you're going to have to downgrade those hopes to pipe dreams.
While in Japan ahead of the Tokyo Motor Show, Autoblog had a chance to sit down with American Honda CEO Tetsuo Iwamura (pictured at right). When we asked about the potential for a new sports coupe or convertible in the Honda or Acura lineup, he pointed to the current Civic and Accord coupes - not to mention the upcoming new NSX - but said that Honda has no replacement for any of the aforementioned models (or a rival for the FR-S or 370Z) in the pipeline, saying only that the company is monitoring potential demand.
What Iwamura-san did note was that he's a personal fan of the new S660 roadster (pictured above) set to be unveiled tomorrow, and he is pushing (or at least hoping) that it will come to North America. Given that he's head of both Honda's American office and its global automobile operations, one might think that the only person he would have to persuade is himself (well... himself, and potential buyers), but the sporty droptop looks to be about kei-sized, which sadly suggests that it may be too small for American tastes and perhaps not designed with US crash-test standards in mind anyway.
