A smoother operator | 2017 Acura MDX Sport Hybrid First Drive

Tue, Apr 4 2017

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.

2019 Acura ILX first drive | New looks, same lackluster performance

Mon, Oct 29 2018

Acura knows what it takes to make a fun, compact car that enthusiasts desire. It did so for three decades with the Integra, which eventually morphed into the still fun RSX. Then the ILX came around for the 2013 model year, and the world collectively yawned. It's actually still yawning, and the 2019 redesign isn't doing a whole lot to change that. One might expect more wholesale changes from a car entering its seventh year on the market, but we're still staring down the barrel of the same 201 horsepower 2.4-liter naturally aspirated four-cylinder and trick dual-clutch automatic transmission (which also features a torque converter for low-speed smoothness) from before. These pieces aren't necessarily the problem though. It's enjoyable to thrash the engine out to 7,000 rpm, and the dual-clutch snaps off surprisingly quick shifts when using the paddles in manual mode. It's a bit of a throwback to before all of Honda's performance engines switched to turbocharging for power. It pulls harder the more you wring it out, and begs to be paired with a slick-shifting six-speed manual like it was in the ninth-gen Civic Si. Sadly, everything else outside the powertrain (still) just misses the mark. The greatest part of Acura's old performance compacts was how they made you feel when you were driving them. There was an intimate connection between the driver and road at all times that is sorely lacking from the ILX. Turn in feel is soft and doesn't offer satisfying quick changes of direction. The old chassis feels its age in controlling body movements too. It all culminates in making the ILX feel like a larger car than it actually is. That's not to say the ILX handles poorly, though; it simply does so without any eagerness or feel — just like it has from the beginning. This is unfortunate because the ILX looks better than it ever has. Acura re-did the whole front nose from the A-pillar forward, and it attacked the rear fascia too. We got to check out and drive A-Spec trimmed cars, which add even more aggression to the styling but no performance upgrades. Sure there's three-too-many fake air vents, but the car finally grew some teeth compared to the ultra-bland looks from before. Props for not following the terrible industry trend of totally unreasonably-sized fake exhaust outlets too. The interior isn't as exciting.

2016 Acura NSX: Everything there is to know [w/video]

Mon, Jan 12 2015

The road to supercar stardom is littered with missteps. For every slam-dunk like the McLaren F1 and Ferrari F40, there are contenders that never quite reach their full potential – think Mercedes-Benz SLR McLaren and Jaguar XJ220. Fear of building a mediocre halo car is why automakers take costly detours like reverse-engineering a carbon fiber chassis when aluminum just won't do (we're looking at you, Lexus LFA), and it's often those second, third, and even fourth major redirects that can make the difference between has-been and hero. History has been kind to the late, great Acura NSX. Though its final years saw it lagging in power, ballooning in price and burdened by unsightly bubble headlamps, the NSX went to pasture in 2005 with a reputation for being an innovative, driver-focused ride that also happened to be practical enough for daily use. Despite its lofty aspirations and attainable price point, fifteen years of production saw just under 9,000 NSXs on the road, which begs the inevitable question: was Acura's mid-engine top dog too tame to be great, yet too ubiquitous to be exotic? Considering how the NSX redux has been worked (and re-worked as a stillborn front-engine V10 GT, only to return to a mid-engine layout), it's safe to say Acura is intent on securing supercar greatness. While the essential spirit of the original NSX program targeted the "New Sports Experimental" idea, Large Project Leader Ted Klaus says that Shigeru Uehara, the man responsible for the original NSX (and Honda S2000, among others) advised the US-based development team that they ought to be "... open-minded to doing things for the emotional benefit of the customer," and not come from a place that was "hyper rational." In other words, build a car that makes the heart skip a beat. View 8 Photos As such, the next-generation NSX has departed from the 2013 concept and assumed a more emotional, expressive design language that hides a more engineering-intensive drivetrain. Gone is the naturally aspirated, transverse-mounted V6, replaced with a longitudinally mounted, turbocharged, dry-sump V6 that produces "north of 550 horsepower," according to Acura brass. As before, the internal combustion mill works with three electric motors to deliver power to all four wheels. Super Handling All-Wheel Drive, indeed – or, as Acura refers to it in this application, Sport Hybrid Super Handling All-Wheel Drive. Why the shift?
