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.

2014 Acura RLX gets trick hybrid all-wheel drive system for LA

Acura has endured a year of mixed reviews and middling sales for its new RLX flagship. Meanwhile, the Japanese automaker has been readying what may be the very best version of the car for its debut. Now the wait is almost over, as Acura will show its 2014 RLX Sport Hybrid SH-AWD at this year's LA Auto Show.
When it comes to dealerships in the spring of 2014, the RLX Hybrid will be the most powerful production car Acura has ever sold. The combination of a 3.5-liter V6 and three electric motors - a 35-kilowatt motor pushing torque to the front wheels and two 27-kW units feeding the rears - creates a total system output of 377 horsepower.
Those rear-end electric motors do more than just add power, they also drive the rear wheels without a traditional rear drive shaft and differential. This newest iteration of the Super Handling-All Wheel Drive calls upon the two rear motors to both drive and brake the rear wheels, vectoring torque in cornering situations for additional grip. All three electric motors make use of regenerative braking to feed electricity back into the system's 260-volt lithium-ion battery pack.
