ACURA Sport Car | Acura MDX Sport Hybrid 2017



   Acura's biggest hitting gains a hybrid halo
The hope of hybrid technology scientific discipline is that it tin lav construct vehicles better—more efficient, superior inward performance, in addition to to a greater extent than satisfying to drive. But that hybrid halo oftentimes is held on yesteryear bobby pins in addition to duct tape. In many luxury hybrids, off-the-rack gasoline-electric technology scientific discipline tin lav construct for an underwhelming, slow-witted driving experience, fifty-fifty if they sometimes are objectively quicker than their less expensive nonhybrid counterparts.
The 2017 Acura MDX Sport Hybrid SH-AWD is a rare exception, every bit it lives upward to its potential, at to the lowest degree upon our kickoff exposure. Part of the argue probable is the years of intense evolution behind its primal hybrid components. Core items from the NSX supercar (and the forgotten—and forgettable—RLX Sport Hybrid sedan) have got been transplanted into what is the brand’s best-selling vehicle. The technology scientific discipline that makes the NSX then ferocious inward the corners in addition to then drama-free inward full general adds confidence, a sharper driving experience, in addition to to a greater extent than miles per gallon to this high-riding, seven-passenger menage unit of measurement wagon.


   Better Reaction Times All Around

The nonhybrid MDX SH-AWD is a tough deed to follow; it’s amid the best-handling three-row crossovers, amongst quick, well-weighted steering in addition to well-controlled trunk motions. Both MDX models characteristic an all-wheel-drive system—optional inward the regular one, measure inward the hybrid—that sends to a greater extent than torque to the exterior raise bicycle during difficult cornering, but the Sport Hybrid goes a mensuration farther amongst the powerfulness to apply resistance (and recover energy) at 1 raise bicycle spell it’s delivering forrard momentum to the other. It therefore achieves a sophisticated in addition to to a greater extent than nuanced shape of torque vectoring. The hybrid arrangement also does away amongst a mechanical connection betwixt the engine in addition to the raise axle. Instead, a Twin Motor Unit (TMU) packages 2 36-hp motors together at the rear. They fill upward gaps inward the engine’s torque bend to sharpen accelerator answer inward the hybrid compared amongst the conventional model, in addition to Acura engineers boast that the arrangement takes precisely ninety milliseconds to fully adjust the torque distribution amid the wheels versus nigh 0.2 2nd inward the regular MDX. In front, a third, 47-hp electrical motor spins amongst the input shaft of the seven-speed dual-clutch automatic transmission in addition to has 3 roles: delivering supplemental torque, helping shine out shifts, in addition to acting every bit a generator.
As for the transmission, it’s a partner inward this system’s quick reaction times. By losing the ZF nine-speed automatic, which tin lav bumble over its bounty of ratio choices (and sometimes fumbles the shifts themselves amongst a shudder), the seven-speed in addition to hybrid motor arrangement are all business, ripping through the gears amongst quickness in addition to grace. You listen them travel to a greater extent than than experience them, and, because of the hybrid system, the rush of passing powerfulness starts fifty-fifty earlier the transmission has downshifted.
The gasoline engine steps aside every bit the headliner of the show, fifty-fifty though it remains the essential piece. In house of the direct-injected 3.5-liter V-6 inward other MDX models, the hybrid has a 3.0-liter V-6 amongst port injection, the smaller displacement enabling it to skirt a China-market taxation on larger engines. The entire arrangement makes 321 horsepower in addition to 289 lb-ft, or 31 hp in addition to 22 lb-ft to a greater extent than than the nonhybrid models.


Moving along amongst metropolis traffic, it’s clear that Acura’s hybrid know-how extends to to a greater extent than than carving upward mountain-road esses. The hybrid arrangement brings the V-6 seamlessly into the mix amongst a moisture multiplate clutch, finessing the low-speed drivability issues that tin lav plague such a setup. Accelerate gently in addition to the MDX hybrid launches silently, every bit a rear-wheel-drive electrical vehicle. The V-6 comes on presently thereafter, although it oftentimes switches off when coasting (at speeds upward to 56 mph). We also saw it cycle off inward steady 40-mph cruising.
The fine MDX driving experience hasn’t been adulterated inward whatever other way. It includes well-blended brakes in addition to precise, nicely weighted steering. There’s a fair amount of trunk lean, every bit expected inward an SUV similar this, but the adaptive dampers do a bully project filtering out route harshness. Push difficult into tight corners in addition to yous powerfulness honour yourself dialing inward every bit good much steering input, every bit the exterior raise motor nudges the vehicle’s rotation, preempting understeer. H5N1 quick loop inward a Lexus RX450h—the top seller amid the MDX hybrid’s U.S.-market rivals—showed a abrupt contrast amongst the agency Acura’s hybrid arrangement doesn’t alter accelerator answer every bit the powerfulness sources swap inward in addition to out, therefore reinforcing the thought that the arrangement works every bit 1 cohesive unit.

   Aiming to Blend In


Compared amongst the NSX or fifty-fifty the RLX, at that spot was a greater attempt to construct the hybrid technologies invisible inward the MDX, according to production planning managing director Gary Robinson. The priorities hither were but strong acceleration in addition to balanced performance, in addition to exterior of knowing when the engine switches off in addition to on, it’s difficult to discern what the hybrid arrangement is doing in addition to where torque is existence delivered.


There nevertheless are 4 driving modes inward the Sport Hybrid, upward from 3 inward other versions of the MDX. They vary restrain response, steering effort, in addition to damper behavior. The 1 that’s hybrid-exclusive in addition to takes wages of this model’s added functioning is Sport+, which keeps the engine running all the time, freeing upward the front end motor to maximize acceleration in addition to to deal amongst shift quickness.
Acura says the hybrid kit adds 227 pounds to the curb weight of the MDX versus the measure AWD model—which is already roughly 200 pounds heavier than an equivalent front-drive version. But because much of the hybrid hardware is mounted depression inward the chassis, the Sport Hybrid has a centre of bulk that’s nigh an inch lower. The fitment of all this extra hardware has no lawsuit on packaging. Ground clearance is the same every bit that of the measure MDX. Seating is still comfortable for 5 inward the kickoff 2 rows (or four, if yous instruct the Advance model in addition to its second-row captain’s chairs) in addition to practiced plenty for kids inward the 3rd row; the seats plication neat in addition to flat; in addition to cargo infinite is uncompromised.
If the motor systems precisely about the axles are the musculus of the hybrid system, the Intelligent Power Unit (IPU) in addition to Power Control Unit (PCU) are its encephalon in addition to nervus center. Both have got benefited from NSX development, in addition to they’re mounted on additional structures (with crossmembers to assist protect them) that bridge the width of the MDX’s underbody—essentially where the driveshaft otherwise would go. The PCU is liquid cooled, spell the IPU, where the 72-cell, 1.3-kWh lithium-ion battery pack lives, is located nether the centre console in addition to cooled amongst air from the cabin.


   Why Not Go Hybrid?

There are 2 ways to instruct the Sport Hybrid. The Technology packet versions include 20-inch wheels, remote start, blind-spot monitoring, in addition to navigation. The Advance packet adds features such every bit heated in addition to ventilated front end seats, upgraded Milano leather amongst contrast piping, open-pore woods trim, heated second-row captain’s chairs amongst a centre console, sunshades for the 2nd row, in addition to LED fog lamps. All MDXs right away come upward amongst crash-mitigation braking, lane-keeping assist, adaptive cruise control, in addition to other active-safety features.
Given the hybrid’s boost of 8 mpg inward the metropolis in addition to 1 mpg on the highway versus the measure all-wheel-drive MDX at an extra damage of precisely $1500, it’s difficult to conceive of a reason not to instruct the Sport Hybrid over the measure MDX—even for those who tend to do to a greater extent than highway driving.
There are a span of drawbacks, however. For all the NSX-derived wizardry, the arrangement inward the MDX Sport Hybrid isn’t actually meant for high-speed driving. At 84 mph, precisely curt of the raise motors’ 11,000-rpm redline, a one-way clutch decouples them from drive duty. Beyond that speed, the nonhybrid models, amongst their larger 3.5-liter V-6 in addition to less weight, probable would start pulling away from the hybrid. The to a greater extent than meaning number is towing. Whereas the measure all-wheel-drive MDX is rated to tow upward to 5000 pounds, pulling a trailer is non recommended at all for the hybrid, according to powertrain evolution leader Ken Lantz, who claims that the bulk of MDX owners don’t tow anyway.


Other than badging, there’s non much to visibly distinguish the hybrid from other versions. All MDXs received a low-cal refresh for 2017, 1 that’s most noteworthy inward front, where Acura shed the final remnants of the old model’s awkward metallic element beak, subbing inward a to a greater extent than conventionally styled grille. The hood gets some corresponding novel graphic symbol lines, at that spot are novel wheels, in addition to the provide of dual exhausts amount the exterior changes for the 2017 MDX lineup. Inside Acura has introduced second-row captain’s chairs in addition to revamped some of the cut back in addition to surfaces. The companionship expects the MDX hybrid’s target buyer to survive both significantly younger in addition to to a greater extent than affluent than those who instruct for the nonhybrid models. Considering that, the hybrid’s interior feels conservative—if a chip drab—for the mission. And years later its introduction, Acura’s dual-screen infotainment arrangement still confounds in addition to infuriates.
Acura expects to sell solely 5 pct of all MDXs inward hybrid form, but mayhap that volition assay to survive an underestimate. For all the complexity, the hybrid gear makes the MDX improve to drive and less thirsty. Here, the halo seems real.
