Acura MDX Prototype reveals slick new looks, with Type S close behind

The next-generation Acura MDX is here, almost. This three-row crossover you’re looking at is technically being called the MDX Prototype by Acura, but itÂ’s about as close to production as any prototype can get. And what a looker it is. Acura has followed up the slick TLX sedan with another attractive design. With the MDX now the best-selling Acura nameplate of all time, this one was even more important for Acura to get right. Just like the TLX, it benefits from a much longer dash-to-axle dimension, measuring in six inches longer than the outgoing MDX. The pentagon grille, and Chicane-shaped DRLs in the headlights now grace a much wider car. Acura gave this MDX a wider track and a three-inch longer wheelbase, both aiding in making it appear far more graceful and sporty. Acura clearly isnÂ’t holding much of anything back with this MDX Prototype versus the final production car, and weÂ’re liking what we can see so far. Many of the design elements we liked so much on the TLX are transferred over to this crossover body style, and Acura has done so with class. The MDXs you see here are riding on new 21-inch wheels that are bolted up to a new light truck platform and chassis specifically tailored for the MDX. Acura says it provides for more athletic handling, greater ride comfort and a quieter cabin versus the outgoing MDX. ItÂ’s even more rigid than the RDXÂ’s body. Just like the new TLX, Acura has gone with a double wishbone front suspension design to make the MDX an even sportier driver. ThereÂ’s more excitement in the powertrain options for the new MDX, too. Acura promises a Type S version of the MDX is coming with the same 3.0-liter turbocharged V6 youÂ’ll find under the hood of the TLX Type S. It will make 355 horsepower and 354 pound-feet of torque (same as the TLX) in this application. The standard engine will continue to be AcuraÂ’s 3.5-liter V6 that makes 290 horsepower and 267 pound-feet of torque. Both engines will be mated to AcuraÂ’s 10-speed automatic transmission and send power to all four wheels using the latest fourth-generation SH-AWD system. Not all of the performance details are available yet, but Acura says the MDX can be had with four-piston Brembo brake calipers and comes with a drive mode selector that allows you to adjust ride, handling, steering, suspension and powertrain characteristics. More Type S-specific details will need to wait. The interior matches the exterior for flair and elegance.

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.

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.
