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 NSX hybrid wins Time Attack 2 division at Pikes Peak

Acura sent three NSX supercars up the PIkes Peak Hill Climb and one of them - the TA2 that was a standard NSX with some additional safety equipment - beat out its competition in the Time Attack 2 class by over 11 seconds with a time of 10:28.820. Nick Robinson was the driver. This was not his first time atop the podium, as he won the PP250 motorcycle class last year. The EV concept NSX came in second in the Electric Modified class with a time of 9:06.015. That's good enough for third place overall. Acura says that the TA1 NSX - which had a lighter chassis and a modified racing exhaust – "also campaigned." Both the TA1 and TA2 NSX vehicles used the car's standard three-motor hybrid powertrain.

The production-based Acura NSX is powered by Acura's revolutionary three-motor Sport Hybrid Super-Handling All-Wheel Drive™ powertrain (Sport Hybrid SH-AWD®), the first electrified torque vectoring powertrain in the world of exotic sports cars. With added required safety equipment for competition, the NSX negotiated the 12.42-mile course in a time of 10:28.820 to win the Time Attack 2 class of the Broadmoor Pikes Peak International Hill Climb. Nick Robinson, North American R&D team member and engineer in charge of the next-generation supercar's dynamic performance, drove the production-based Acura NSX to victory. Nick is also the reigning PP250 winner from the 2015 Pikes Peak International Hill Climb. "I'm incredibly happy to have won the Production Class with the new NSX!" Robinson reported.

2014 Acura MDX Prototype is exactly what we expected

Yep, it's the new MDX. And despite being totally redone, it looks exactly like we expected. That is, it's an up-sized version of the RDX crossover with fancy LED lights stolen from the RLX sedan. And while that might not sound too exciting, we have to say, it is handsome - certainly a more cohesive, refined design than the angular, beak-tastic model that's currently on sale.
Acura is calling this 2014 MDX a prototype, but that's only because it isn't 100-percent finished. Everything you see here will likely carry over to production, maybe with a couple small tweaks. Under the hood is the same 3.5-liter V6 that we know and love from the Honda group, and while we don't have power figures just yet, Acura says it will deliver more torque while improving efficiency. In redesigning the MDX, the Japanese automaker has managed to lighten and stiffen the chassis, improving driving dynamics. More interestingly, for the first time Acura will offer a front-wheel-drive version of the MDX, but don't worry, the automaker's SH-AWD all-wheel drive will be available.
Inside, the usual smattering of tech goodies will be on hand, including the next-generation AcuraLink system, satellite radio, tons of comfort amenities and every single alphabetic safety device known to man (okay, maybe not all of them).
