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 NSX Type S Track Drive | One lap of Daytona

DAYTONA BEACH, Fla. — Stadium lights shine their bright white glow on the tarmac as I power out of the infield and up to the banking of NASCAR 1 at Daytona International Speedway in the 2022 Acura NSX Type S. The force of gravity quickly changes from normal to feeling like IÂ’m being shoved down by a compactor. I gingerly arc down from the top of DaytonaÂ’s steep 31-degree incline and settle into the middle, right pedal down and holding the wheel steady. That last part, I quickly learn, is unnecessary, as the banking holds the car in place without needing to exert much steering force. An immersive and sonorous note trumpets through the cabin as I stay in the throttle out of NASCAR 2. The Bus Stop Chicane (just renamed the Le Mans Chicane for this yearÂ’s Rolex 24) arrives quickly and with little warning when you have 600 horsepower hustling you there, and itÂ’s perhaps the worst-lit corner on the track — ironic, considering youÂ’re going as fast as anywhere at Daytona before having to apply the brakes. A loud, brap, brap, brap accompanies the slowdown. I smash over the rumble strips while exiting the chicane, and head back onto the oval for another go in the compactor for NASCAR 3 and 4. And then that's it, my one flying lap in the one-year-only NSX Type S is over. Rolling back into pit lane, IÂ’m attempting to process what just happened, but am reduced to one-word exclamations from the adrenaline rush. Piloting anything on-track at the Daytona road course at night is a bucket list, dream-come-true moment for a racing enthusiast, and I had just done it in AcuraÂ’s mid-engine supercar. Turns out, those hundreds of hours playing Gran Turismo and dreaming finally came in handy. This brief and high-speed track drive is our first go at the new-for-2022 NSX Type S. Acura says that more seat time is coming in the future, but weÂ’re to make do with this quick taste for the time being. That said, even if you wanted to at this point, the chances of buying a new NSX Type S are next to zero. The NSX swan song — yes, this is the NSXÂ’s last model year — sold out in mere minutes, and all thatÂ’s left is a waiting list. Acura is building 350 total, and 300 are allocated for the United States. There will be no “standard” NSXs for 2022 either, so itÂ’s either the $171,495 Type S or nothing. Despite the rarity and short life, it's surprising how much effort Acura put into enhancing the NSX's complex engine and three-motor hybrid system.

Honda insiders push for Acura NSX Type R sans hybrid tech

With 500 horsepower on tap from a sophisticated hybrid powertrain, there's plenty to love about the new Acura NSX. If the more performance-oriented elements within the Japanese automaker get their way, it could get even better. Speaking with one of the NSX project's chief engineers Nick Robinson at the launch of the new supercar, Autocar reports that there's an effort underway to develop an NSX Type R. Following a much-loved formula, the more extreme variant would pack even more power than the existing version, unburdened by excess weight. A big part of the targeted weight savings would come from ditching some of the heavier components from the hybrid system. The electric motor at the rear could stay to serve as alternator, starter motor, and flywheel. But the electric motors at the front would go, helping to shed a few hundred pounds. Throw in some lightweight materials and we'd be looking at a considerable weight reduction. It could even integrate some active aerodynamic elements that were excluded from the NSX on the road to production. Though the project may still be a ways off from getting the green light, but Robinson and some of his colleagues are working on prototypes ostensibly to make the case. He and his brother James (a powertrain engineer at Honda) will be driving a pair of NSXs at Pikes Peak this year – one that's as close to showroom stock as the regulations will allow, but the other will be closer to what they have in mind for a Type R. It'll ditch the hybrid system and put an electric compressor in its place to eliminate any turbo lag and produce even more power than the existing model. Now if they can only get the go-ahead from the higher-ups at Honda.
