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.

Autoblog Minute: VW finds CO2 'irregularities', Takata dropped by automakers, SEMA recap

Volkswagen's diesel emissions scandal gets a new wrinkle, US regulators hit Takata Corporation with a substantial fine, and we head to Las Vegas for a look at tuner paradise at the 2015 SEMA show. Autoblog senior editor Greg Migliore reports on this edition of Autoblog Minute Weekly Recap. Show full video transcript text [00:00:00] Volkswagen's diesel emissions scandal gets a new wrinkle. US regulators issue a significant fine to Takata Corporation. And we take a peek inside tuner paradise at the 2015 SEMA show. I'm senior editor Greg Migliore and this is your Autoblog Minute Weekly Recap. The VW diesel emissions scandal, first brought to light in September, gets a new wrinkle, as an internal investigation by the German automaker revealed [00:00:30] irregularities in CO2 emissions that could affect approximately 800,000 vehicles. VW estimates the issue could pose a 2-billion euro economic risk. VW claims that most of the vehicles affected have diesel engines, but industry analysts say a 1.4-liter gas engine is also affected. VW says that fuel consumption figures were set too low during the CO2 certification process. During all of this, sales of some diesel-powered Volkswagen, Audi, and Porsche models [00:01:00] have been halted. Takata Corporation is back in the news in connection with its deadly airbag scandal. Federal regulators fined Takata $70 million. If the parts supplier does not comply, the fine could balloon to $200 million. Takata was also dropped this week by its biggest customer, Honda. And now, Toyota and Mazda will be following Honda's lead in dropping Takata. We're also hearing that Mitsubishi and Subaru are considering a switch in air-bag inflator suppliers. SEMA 2015 [00:01:30] came and went. We saw offerings from Mopar, like the AWD Challenger concept. Honda unveiled a Ridgeline that it will race at the Baja 1000, which gives us a hint at what future production model could look like. The celebrity presence was also felt in Vegas as it always is. Kid Rock brought a Duramax Diesel Chevy Silverado, and Acura restored and presented Ludacris with his now famous 1993 Acura Legend. Those are the highlights from the week that was. Be sure to come back on Saturday for my full recap, [00:02:00] where I'll have some added insight into Hyundai's foray into the luxury sector. For Autoblog, I'm Greg Migliore.

2024 Acura ZDX revealed with up to 500 horsepower

The 2024 Acura ZDX electric SUV has been revealed along with many of the basic specifications. It will be available in two basic trims, the A-Spec and the Type S, and both offer fairly impressive performance and range wrapped in a package that's very similar to the Precision EV concept. The basic shape of the ZDX is quite close to the Precision, but everything has been softened. The nose still leans forward with a solid main grille, it has a floating roof, silver lower trim and a cab-rearward shape. Concessions to practicality include the conventional door-pulls and larger lower grilles for powertrain cooling. The A-Spec and Type S look pretty similar, with the main difference being wheel size: 20 inches for the A-Spec and 22 for the Type S. The A-Spec's tires are also 265-mm wide while the Type S gets 275-mm tires. And that top-trim ZDX gets the option of the Double Apex Blue Pearl from the concept, or the Tiger Eye Pearl from other Type S models. Unlike the Precision, the ZDX actually has an interior, and it does a good job of hiding its GM roots, at least at first glance. It has a low dash with slim air vents and a pair of screens for instruments and infotainment; 11 inches and 11.5 respectively. The screens are split up, and sit low behind a wraparound cowl design. Looking closer, though, and you'll see that the steering wheel and climate controls are carryover from the related Blazer EV, though that's not necessarily a bad thing. Acura has another important difference from the GM products: It will feature wireless Android Auto and Apple CarPlay, in addition to all the Google Built-In apps. An 18-speaker Bang & Olufsen sound system is standard, too. Other fancy tech includes rear emergency braking with rear cross-traffic and pedestrian detection, blind-spot monitoring with steering assist, automatic parallel parking and, thanks to being based on a GM platform, hands-free highway driving assist (Super Cruise by any other name). Digging beneath the surface, we find that the A-Spec will come standard in rear-wheel-drive form, quite the departure from a company with decades of front-drive history and experience. It gets a single rear motor making 340 horsepower. It will be available with a dual-motor all-wheel-drive powertrain that we're presuming has the same total output, seeing as Acura didn't specify a different amount. Multi-link independent suspension with fixed shocks and springs are also standard for the A-Spec.
