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.

A look inside Honda’s “Safety For Everyone” research and development operation

RAYMOND, Ohio—As part of its long-running “Safety for Everyone” campaign, Honda has established the audacious goal of what it calls a “zero-collision society.” But rather than making big claims about developing a fully-autonomous vehicle, which Honda hasnÂ’t done, the company is trying to chip away at the more than 37,000 vehicle-related fatalities that occurred in the U.S. in 2017 with a multi-pronged approach. Here in central Ohio, engineers are working with state-of-the-art facilities and equipment to boost active safety systems like its HondaSensing suite of safety technology with old fashioned passive systems like structural steel frames or new airbag designs that protect passengers in a crash. Honda provided members of the press with a rare tour inside its Honda R&D Americas headquarters this week. Honda officials say that increasingly, safety — and specifically, third-party ratings from the likes of the National Highway Safety Traffic Administration and the Insurance Institute for Highway Safety — figure into the top three factors consumers weigh when purchasing a vehicle. Honda and Acura have 10, 2019 models that have earned IIHSÂ’s Top Safety Pick or Top Safety Pick+ ratings, and all 15, 2019 model-year Honda and Acura vehicles that have undergone NHTSA crash testing have earned a 5-star overall rating. And Honda prides itself on its growing list of safety firsts, including the first upward-deploying front passenger airbag, in 1990 in the Acura Legend; first omni-directional crash-test facility, in 2000; and the first autonomous braking system, in the 2006 Acura RL. It hopes its new three-chamber airbag goes industry-wide and joins that list. “ItÂ’s part of our companyÂ’s culture,” said Art St. Cyr, business head unit and vice president of auto operations for American Honda Motor Co. “We have a philosophy at Honda that we want to be a company that society wants to exist. That means we have to protect our customers. ThatÂ’s part of the whole mantra of doing this.” Opened in 1984, the 1.6 million square-foot Honda R&D Americas facility, located in the countryside about 45 miles northwest of Columbus, employs around 1,600 people and is HondaÂ’s largest research-and-development facility outside of Japan. Its Advanced Safety Research facility opened in 2003.

2019 Infiniti QX50 vs. compact luxury SUV rivals: How they compare

With apologies to the EX35, or whatever it was eventually renamed, Infiniti has been without a proper, competitive entry in the compact luxury SUV segment. You know, the segment that's growing faster in sales and entries than any other? To say the 2019 Infiniti QX50 is long awaited would therefore be an understatement. At first glance and drive, the new QX50 would indeed seem to be wildly more competitive than its predecessor, which come to think of it, was eventually called the QX50 as well. This one is based on an all-new front-wheel-drive platform, and although it lacks the inherent verve of the old, rear-drive- and 370Z-based one, the resulting increase in cabin space should be a welcome tradeoff. In fact, as you'll see below, the QX50 has gone from one of the smallest compact SUVs to the most spacious. How does it stack up in every other way? Say, against the segment's four best-selling entries last year: the 2018 Lexus NX 300, 2018 Acura RDX, 2018 Audi Q5 and 2018 BMW X3. On paper at least, really well as it turns out. Let's go to the spreadsheet! Discover and compare other luxury crossovers with our Car Finder and Compare tools. Comparing engines, drivetrains and transmissions With the exception of the Acura, all of the contenders come with 2.0-liter turbocharged four-cylinder engines. As you can see, the Infiniti is the heavyweight amongst the four-bangers, boasting the most horsepower and torque. The Acura V6 nips it by 11 hp, but the QX50 is still the overall torque champ. Plus, as we documented in the QX50 first drive, the Infiniti's new VC-Turbo engine is also the most technologically advanced. The Lexus is the wimp of the group and is also the second-heaviest, which isn't exactly the ideal scenario. The Infiniti is the only one in the group to feature a continuously variable transmission. That's not going to generate much applause around here. The BMW tops the gear count with eight, while the Audi is the only entry with a dual-clutch automated manual. The Acura and Lexus have only six gears, but they're good transmissions and it's not like their fuel economy is off the pace. The Audi and BMW come standard with all-wheel drive, while the others offer a choice of front- or all-wheel drive. Comparing cargo and interior space The new front-wheel-drive platform is paying dividends inside for the 2019 QX50, as it now boasts the most maximum cargo space at 65.1 cubic feet.
