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.

2019 Acura RDX named a Top Safety Pick+ by IIHS

To the accolades being heaped on the all-new 2019 Acura RDX, the automaker can now add another: a Top Safety Pick+ designation from the Insurance Institute for Highway Safety, the organization's coveted top rating. IIHS cites the SUV's good crashworthiness ratings, standard front crash prevention technology and even the availability of "good"-rated headlights, which has become perhaps the group's most daunting hurdle. To qualify for IIHS's top award, a vehicle must earn "good" ratings in the driver-side small overlap front crash test, moderate overlap front, side, roof strength and head restraint tests and an "acceptable" or "good" rating in passenger-side small overlap test. The RDX earns "good" ratings across the board. IIHS also rated the standard AcuraWatch safety technology as "superior," saying it avoided collisions at 12 and 25 mph, and it rated the base LED headlights as "good" and the curve-adapted headlights on the top-of-the-line Advance trim as "acceptable." Autoblog recently learned that 40 vehicle models earned good enough crash ratings to qualify for IIHS' Top Safety Pick rating but fall short because they don't meet the organization's criteria for good headlights. Acura says the 2019 RDX features the newest generation of its Advanced Compatibility Engineering body structure, plus new high-strength steel door stiffener rings and eight airbags. The AcuraWatch suite of safety technologies includes collision mitigation braking, adaptive cruise control and road departure mitigation, all standard. The RDX is powered by a 2.0-liter turbo-four engine that makes 272 horsepower and 280 pound-feet of torque and comes with a 10-speed automatic. The compact luxury crossover went on sale June 1 and set monthly sales records in both June and July. You can find Autoblog's driving review of the 2019 RDX here. Related Video:

2020 Acura NSX leads this month's list of discounts

With its 573-horsepower hybrid powertrain and 0-60 time of 2.9 seconds, there's no doubt that the Acura NSX is an impressive machine. As its production numbers and pricing adjustments attest, however, it's not a big seller. And this month, Acura's high-end coupe has a larger monetary discount than any other vehicle in America. Buyers of the 2020 Acura NSX are scoring an average cut of $19,659 off the car's $159,530 sticker price. That equals a 12.3% savings for an average transaction price of $139,871. That's still a hefty chunk of change, but it's a reasonable sum for a vehicle with the NSX's performance chops. The next two vehicles in order of largest discounts follow the same luxury performance coupe trend. The Audi R8 is a much pricier vehicle than the NSX, which means its $16,146 discount only represents 8% off its average $200,086 sticker, but we doubt buyers are complaining. Next up is the BMW M8, a vehicle that has been at or near the top of this list more than once. The M8's average discount of $15,403 represents a 10.4% savings off its $148,880 retail price. Interestingly, that puts the M8 and NSX within a few thousand dollars of each other.
