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 confirms more 2016 NSX details

Acura served up a slew of engineering details about the soon-to-launch 2016 NSX. Fittingly, they were explained at a dinner at the SAE International World Congress in Detroit, where morsels about the new Acura supercar were likely gobbled up quicker than the main course. Among the highlights: The NSX will mark Acura's first use of a multimaterial space frame, and it includes high-strength steel and aluminum. This will allow the NSX to hit its weight targets, while maintaining rigidity. The NSX uses a so-called "ablation" technology, which allows the ultra-rigid castings to be used within the car's crush zones. For more details on this, scroll through the press blast below. As expected, the NSX will pack a twin-turbo V6 engine, and Acura confirmed it will displace 3.5 liters. The unit will be mounted amidships and team with hybrid components to increase performance and efficiency. The supercar also features the most advanced evolution of Acura's Super Handling All-Wheel-Drive system, and it's capable of distributing more torque than any other setup the brand has used. The NSX has 10 air-cooled heat exchangers that will cool the powertrain, and the V6 alone will have three radiators. There are also twin intercoolers in the side air intakes that further cool the system. The next generation of the NSX was unveiled in January at the Detroit Auto Show, and production launches this fall in Ohio.

DETROIT, April 23, 2015 – In advance of the market launch of the highly anticipated next generation Acura NSX, the engineers leading the supercar's development shared new technical details and design strategies with the automotive engineering community at the April 22nd SAE Detroit Section dinner, held in conjunction with the SAE 2015 World Congress and Exhibition. Additional information about the team's efforts to achieve a true "New Sports Experience" included details of the NSX's world's first body construction process that helped create a multi-material space frame resulting in class-leading body rigidity, the advanced total airflow management system and an update on NSX's power unit specifications. Ted Klaus, chief engineer and global development leader of the new NSX, introduced key powertrain, body and dynamic performance engineers who shared new product and technical details in their related areas of the development.

Acura replaces chief Accavitti with designer Ikeda

Acura is shaking up its senior leadership, as Honda ushers the current chief of its luxury division out the door and replaces him with a new one. Exiting stage left is Mike Accavitti, who held the reins at the premium automaker as its senior vice president and general manager of the Acura division. Taking his place will be Jon Ikeda, one of the Japanese automaker's most senior designers. Accavitti (pictured above at left) had been promoted to the job from his previous position as senior vice president of auto operations after Honda separated the Acura brand into its own division. He had previously served as a senior executive at Chrysler, rising up the ranks to run the Dodge brand, and joined Honda in 2011 as its chief marketing officer. At this point it remains unclear why Accavitti is leaving and where he might land, but Honda says he's leaving the company altogether. To replace Accavitti, Honda has named Jon Ikeda (pictured above at right), a veteran designer with the company. A graduate of the Art Center College of Design in Pasadena, CA, Ikeda has worked for Honda on both sides of the Pacific since 1989. He previous headed up the design and product planning divisions at Honda's American R&D operations, and was instrumental in creating an independent design office for the Acura brand, separate from Honda's. This isn't the first time we've seen Accavitti replaced in his role as a senior executive by a design veteran. After only four months at CEO of the Dodge brand, he was replaced by Ralph Gilles, who retained his role as senior vice president of design for the entire Chrysler group in parallel. Gilles was ultimately replaced as head of Dodge as well, but was recently promoted to serve as head of design for Fiat Chrysler Automobiles.

July 27, 2015 – Acura today announced that Jon Ikeda has been promoted to Vice President and General Manager of the Acura Division of American Honda Motor Co., Inc. In this role, Ikeda will oversee all Acura brand activities including sales, marketing and parts and service. Ikeda was formerly Division Director of Auto Design at Honda R&D Americas, Inc. (HRA). He began his career at Honda in Japan in 1989, joining the advanced design studio in Tokyo, where he worked on the award-winning Honda FSX show car. After six years in Japan, he returned to Los Angeles in 1995, to continue his career at Honda R&D in Torrance, California.
