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.

Acura recalls some 2022 TLXs for potential slashed tires

Acura has issued a recall that applies to less than 20 units of the 2022 TLX sedan. The cars included in the campaign were manufactured with tires that may have been damaged by part of a robotic arm while being sorted and stored at a Bridgestone facility in Tennessee. Assigned recall number 22V-950 by the National Highway Traffic Safety Administration (NHTSA), the campaign includes 19 units of the TLX built on September 1, 2022, and Acura estimates that 95% of them may have been built with damaged tires. The company explains that the tires fitted to these vehicles could have sustained cuts and/or tears because a protective plastic shoe located at the base of a robotic arm used to unstack tires exposed a sharp edge by rotating out of position. Damaging a tire's bead area can cause it to gradually lose air; the problem can also manifest itself through unusual noises or vibrations. The tire pressure monitoring system could warn the driver of an issue. The tires in question are Bridgestone's 235/50R18 Turanza EL440. Acura states that it's not aware of warranty claims, field reports, injuries or crashes related to the issue, and Bridgestone says that human workers are now tasked with loading and unloading tires in its facility. Owners of affected cars will receive details about the recall campaign by mail starting on January 30, 2023. They'll be asked to take their TLX to a dealership to get the tires inspected; new tires will be installed free of charge if the ones on the car fall within the affected date range. Drivers who experienced a problem related to this recall and paid to get new tires installed will be eligible to ask Acura for a refund. Related video:

2020 Acura MDX PMC Edition coming to L.A. Auto Show

The Acura TLX PMC Edition debuted at the New York Auto Show earlier this year, the 2020 Acura MDX PMC Edition takes its turn in Los Angeles on November 20. The MDX PMC, hand-built at the Performance Manufacturing Center like the Acura NSX and TLX before it, will be limited to 330 units. The 300 examples destined for the U.S. and 30 for Canada represent 30 fewer units than the quota for the TLX PMC. That could translate into tighter demand for the MDX PMC, since the standard crossover does about 70 percent more business in the U.S. than the standard sedan. The doted-on MDX PMC follows the formula of combining Valencia Red Pearl paint with the normally-exclusive Advanced and A-Spec packages. Dark contrasts come from the body color grille surrounding gloss-black mesh, black chrome exhaust finishers, gloss-black decorating the roof, antenna, exterior mirrors, window molding, rear license plate garnish, and door handles, and gloss black 20-inch wheels. Inside is found an A-Spec steering wheel backed by metal-finished paddle shifters, black Milano leather seats with Alcantara inserts, red stitching throughout, and an individually numbered plaque identifying the build number. Extra luxury kit includes GPS-linked climate control, climate-controlled front- and second-row seats with second-row captain's chairs, and 10-speaker ELS Studio audio. The engine specs don't change, those being a 3.5-liter V6 with 290 horsepower and 267 pound-feet of torque shifting through a nine-speed automatic. Super-Handling All-Wheel Drive keeps the power in shape. When the automaker laid down a marker for the TLX PMC price, it said to expect something around $50,000, the final figure after destination coming in at $50,945. Acura says to expect the MDX PMC to figure in the "mid-$60,000 range," so don't be surprised at $66K minus some change.
