Acura RLX Sport Hybrid SH-AWD set for LA debut

Acura has announced that it will be showing the production version of the RLX Sport Hybrid SH-AWD at the 2013 Los Angeles Auto Show. You'll recall that the standard 3.5-liter V6-powered RLX has been on sale for some time, and that our review of Acura's flagship sedan was mixed. On paper, at least, the RLX Sport Hybrid SH-AWD should fare better.
Sporting a similar hybrid powertrain to the one expected to motivate the NSX supercar, the RLX uses a 3.5-liter V6 paired with a seven-speed dual-clutch transmission and a trio of electric motors to generate 377 horsepower, net a combined fuel economy of 30 miles per gallon and offer the security and performance of torque-vectoring all-wheel drive.
The RLX will hit the LA stand on November 20. Scroll down for the full press release from Acura.

2019 Acura MDX refresh brings some sharp enhancements

The outgoing Acura MDX has nothing to be ashamed of, but the thing about refreshes is that the engineers and product teams always have something to fine tune. Some of it is planned in advance — the cosmetic upgrades and the A-Spec trim were probably always part of the product roadmap. But there are also some tweaks that seem to be a response to customer feedback. Let's take a closer look. Most important, some of the goodies reserved only for the old Sport Hybrid will now be available on all MDXs. Notably, the Active Damper System — a continuously adjustable valve that controls the flow of hydraulic fluid within the damper — is available on non-hybrid MDXs for the first time. The system has several settings, from plush to firm. We found this system worked very well on the Sport Hybrid during our first drive, so it's a useful upgrade that buyers will be able to readily appreciate. Next up is an A-Spec appearance trim, which looks sportier but doesn't offer any additional performance or comfort features, just like the rest of Acura's A-Spec models at this point. For the MDX, wider 20-inch wheels and a combination of gloss black and "dark chrome" trim compliment a revised front fascia and grille. Inside, the seats get a mix of Alcantara and leather with contrasting stitching, there are unique gauges, sport pedals, and a thicker steering wheel. It looks decent enough, particularly inside, and there's enough there to make the trim stand apart from the more pedestrian trims. Oh, and there's an exclusive color: Apex Blue Pearl. A quick aside on prices: The base MDX without SH-AWD runs an MSRP of $45,295, and the A-Spec (only available with SH-AWD) is $55,795. Normal MDXs get a few more color options, although they'll cost extra: Majestic Black Pearl, Performance Red, and Canyon Bronze Metallic. One no-cost color option that's new is Gunmetal Metallic. Inside, there are some additional interior options, like Desert Olive Ash wood trim, contrasting seat stitching, and standard 4-way power lumbar adjustment on the front seats. Advance Package MDXs get wider 20-inch wheels, too. And now on to those tweaks and enhancements that might not have been planned a long time ago in a product meeting far away. The engine stop/start function has been tweaked to be smoother and quicker, thanks to an upgraded brake sensor and some software tweaks.

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.
