cooled power control unit that includes the electronic control unit for the motor, as well as three inverters to convert direct current to alternating current for the three electric motors. It is worth noting that the hybrid system isn't something that is something of an afterthought. According to Todd Hemmert, who was the large project leader (a.k.a., "chief engineer") for the 2017 MDX, when the platform was developed for the third-generation MDX a sport hybrid configuration was taken into account, thereby facilitating the packaging of the hybrid powertrain and electrical components without major modifications to the structure nor attenuating the interior space of the vehicle. Hemmert points out that the power unit and the power control unit, which are positioned fairly centrally (the former below the front row of seats and the latter where the second-row passengers put their feet), require a few different stampings (e.g., cross members) compared with the non-hybrid MDX. Hemmert notes a variety of learnings/borrowings from the NSX for the MDX Sport Hybrid, including the twin motor unit (which he says is different primarily in the gear ratio setup), the algorithm used for the active dampers (there are three G sensors and four stroke sensors used for the MDX), and components used for the electric servo brake system. That said, unlike the NSX, which is about the sort of perfor- mance that one would associate with a track, Robinson notes that for the MDX the "performance is related to confidence and control: 'I've got to pass this semi' or 'I've got to take this corner and it's wet.'" Robinson notes, "A lot of people say they want performance, but what they mean by that is very different." He explains that the MDX is already one of the top-selling SUVs for those under 35. (Ikeda says the MDX is the all-time top-selling three row SUV in the U.S, period.) Robinson points out, "These younger buyers are the group most interested in hybrids. Older buyers are more traditional—interested in 0 to 60 times, handling limits and things like that. Younger buyers are looking for some combination of performance—all luxury buyers are interested in that—and technology itself." So there it is. A seven-passenger SUV that provides perfor- mance and fuel economy (it is rated at 26/27/27 mpg, city/ highway/combined) in a technologi- cally sophisticated package (it offers an enhanced version of Acura's Super Handling All-Wheel Drive thanks to the dynamic torque vectoring of the electric motors). And while vehicles like the MDX Sport Hybrid are generally family vehicles, and while the MDX Sport Hybrid is certainly that, there is something that the vehicle offers, something that goes closer to the NSX. There are four selectable drive modes that adjust steering, suspension, torque vectoring settings and powertrain performance, depending on the category selected. They are Comfort, Normal, Sport and Sport+. The last-named maximizes the powertrain performance by changing the transmission shift and throttle mapping and by providing maximum battery assist at launch. Maybe not full-on NSX, but certainly not grocery-getter. Younger buyers, the group most interested in hybrids, are looking for a combination of performance and technology. info@mvpind.com • mvpind.com The Key To excellenT MeTering Patriot 1:1 Adhesives / Sealants System Designed for the hardest, most critical application • Simplifies day-to-day use and maintenance by eliminating the need for gear and transfer pumps • Self-adjusting pneumatic cylinders • Safety shut off device Available in 10:1 and single component options 28 COVER STORY
