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 will show all-new MDX Prototype in Detroit

Acura says it will show a prototype of its 2014 MDX crossover at the 2013 Detroit Auto Show, and we'll admit that the announcement has left us in a bit of confusion. See, the Acura press release says that the MDX proto will present "Aero Sculpture" design language, "alluring proportions" and "arching body lines." It has been accompanied by a sketch (above, click to enlarge) that, indeed, shows off a swoopy, alluring CUV.
Yet we have spy shots from two months ago of what is supposed to be the 2014 MDX, and unless the camouflage is actually some sort of vehicular moo moo, there isn't really a swoopy line on it. It is stout and substantial, but not in a way that makes us think of "Aero Sculpture." We'll know in a few weeks where the truth resides. It would appear that Acura's rendering artist has done a masterful fade on the rear glass/D-pillar area of the vehicle.
If you want to see the answer in real time, the reveal will be broadcast as it happens on Acura's webcast site. There's a press release below with the details.

2021 Acura TLX Type-S to be powered by 355-horsepower V6

The 2021 Acura TLX Type-S is on track to deliver 355 horsepower, Honda's luxury subsidiary said Thursday, floating the power figure in an announcement that a prototype of its new sport sedan will serve as the pace car for the 2020 Pikes Peak International Hill Climb on August 30. The 3.0-liter V6 will also boast 354 pound-feet of torque, Acura said. These figures put it in the heart of the midsize performance sedan category, alongside the likes of the Cadillac CT5-V (360 horsepower) and Audi S4 (349 horsepower); BMW, Mercedes-Benz and Infiniti all offer more. The 2021 TLX sits on a new, stiffer platform and marks the return of a double-wishbone front suspension.  2021 Acura TLX to Make Racing Debut at Pikes Peak International Hill Climb "Racing is a key expression of Acura’s Precision Crafted Performance DNA. For the past nine years, Acura has utilized the grueling Pikes Peak hill climb as an opportunity to grow the skills of the companyÂ’s young engineers and as a test bed for future performance technologies in Acura production vehicles. The Acura Pikes Peak race team is comprised of a group of volunteer R&D engineers and is responsible for all aspects of the competition, including the development of vehicles, race prep, crew support and navigating race cars to the finish line," Acura's announcement said.  Acura will field two TLX race cars in the Exhibition class at Pikes Peak. Both will be powered by the base, 2.0-liter turbocharged four-cylinder. Based on the company's announcement, it appears that one will be front-wheel drive and the other equipped with Acura's Super Handling All-Wheel Drive (SH-AWD), which is standard on the Type S. This engine makes 272 hp in street tune, but the race cars have received upgrades. The SH-AWD model boasts a larger turbocharger and intercooler for additional power, while the front-wheel-drive model received a milder tune and some suspension tweaks. A Time Attack NSX piloted by James Robinson will accompany the sedans. The Type-S will serve only as a pace vehicle, not a competitive entry.  Related Video:
