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.

2022 Acura RDX First Drive | RDX redux gives us what we want

LOS ANGELES — AcuraÂ’s most recent totally new models — the TLX and MDX — thwacked us upside the head with authority to let us know that Acura as a luxury and performance brand is well and truly back in great form. The redesigned RDX tried to do the same back in 2019, and while it was an above-average overhaul effort, it didnÂ’t move us as strongly as the TLX and MDX have since. Now, the 2022 Acura RDX is here, and itÂ’s packing a bunch of improvements to try and both enhance the driving experience and ensure that it isnÂ’t playing second fiddle to other Acura products in tech or luxury. The one omission, and itÂ’s a big one, is the continued lack of a Type S variant. Both the TLX and MDX offer a high-performance Type S version with turbocharged V6 engines, and the RDX continues to go without such a model in 2022. ItÂ’s a shame, because the RDXÂ’s smaller size means it could serve as a quality platform for a performance crossover to compete against others like the BMW X3 M40i, Mercedes-AMG GLC 43 and Audi SQ5. ThatÂ’s not to say that Acura has neglected the driving experience for 2022. The one performance improvement comes in the form of re-tuned adaptive dampers on the Advance trim that are both stiffer in Sport mode and softer in Comfort mode. Plus, the cabin is much quieter than it was before thanks to additional sound deadening material and an enhanced Active Sound Control system. Acura says the standard car offers a 20% NVH improvement, while the Advance Package cars have even more sound deadening to deliver a 30% improvement over the 2021 model. YouÂ’ll be able to tell the updated RDX apart from the pre-refresh version by looking at the new grille pattern and thinner chrome grille surround. Look further downward, and youÂ’ll notice larger side intakes and a new fog light design. ItÂ’s harder to tell that anything is new from the back, but look closely, and youÂ’ll see a redone lower bumper and rectangular exhaust outlets on every model but the A-Spec — that hangs on to its round dual exhaust tips. A couple of new wheel designs round out the exterior updates, while the interior sees a new bronze-like finish for the aluminum trim in lower trims. Perhaps one of the most vital changes Acura made to the RDX this year is done on the equipment side, as it fixes one of the gripes weÂ’ve had with Acuras over the past couple years. You can finally equip the Advance Package onto A-Spec trim cars.

Honda, Acura recall Ridgeline, Accord, MDX, TLX for various fuel pump issues

Honda and Acura have issued two separate fuel pump-related recalls for Ridgeline pickups, as well as Accord and TLX sedans, and MDX SUVs. Affected Ridgelines could have an increased risk of fire, while the Accord, TLX, and MDX could potentially stall out while driving. According to NHTSA campaign No. 19V053000, Honda is recalling 106,683 2017-2019 Ridgelines because the fuel pump feed port could crack when exposed to certain acids, including car wash soaps. If it cracks, it could leak pressurized fuel, which could catch fire. Vehicles with this defect are subject to a free fuel pump replacement, as well as an extra fuel pump cover. The second recall, campaign No. 19V060000, affects 437,032 2016-2018 MDX, 2015-2019 TLX, and 2015-2017 Accord models equipped with 3.5-liter V6 engines. According to Honda, fuel particulates could stick to internal components of the fuel pump. This could potentially slow down the fuel pump and hinder performance, which could cause the engine to sputter and stall. Honda dealers will update the fuel injection engine control unit software and/or replace the fuel pump, if needed. If you want to know if your vehicle is included in one of these recalls, contact your Honda or Acura dealer, call the NHTSA hotline at 1-888-327-4236, or visit safecar.gov. Related Video:
