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.

2017 Acura NSX | 2017 Autoblog Technology of the Year Finalist

Like its iconic predecessor, the second-generation Acura NSX blazes trails. The old NSX proved that you could get reliability and daily use from an exotic car, and subsequently changed the automotive world. Acura's engineers pushed in a new direction for the prodigal successor: technology. And so the new NSX sets a new bar in the way technology is used to achieve speed. The highlight here is the Sport Hybrid SH-AWD system, which supplements the 500-horsepower twin-turbo V6 with three electric motors, making 573 peak ponies. The two front motors each act on a front wheel, doing all kinds of tricks to help the car corner faster, brake harder, and accelerate like the proverbial cannon shot. They help make the NSX more stable at high speed, and let you sneak up on unsuspecting video producers at low speed. Then there's the third motor sandwiched between the engine and nine-speed transmission, which never lets a shift go by without filling in the milliseconds with velvety torque. If the all-wheel-drive hybrid supercar sounds familiar, yes, Porsche did something similar with the 918 Spyder. But even when you load the options on the NSX (try not to, we dare you), it's never more than a fifth the price of the Porsche. Then there are the little details, like a new form of casting Honda engineers developed for the NSX's crash structure. Or the three-dimensional bend to the A-pillar and roof rail that makes it less obstructive to the driver and also stronger. Even the Marysville, Ohio factory gets some credit here, with 12 patents filed relating to the assembly process. There's only so much a driver can do with two hands and two feet. The NSX takes your inputs and figures out how to maximize the contribution from each individual wheel. This is a car that harnesses all the greatness of technology to change what's possible in a sports car.Related Video: 2017 Acura NSX | First Drive

Next-gen Acura TLX spied out testing in heavy camouflage

We’re sure you all remember that stunning Acura Type S Concept from yesterday. Acura said itÂ’s meant to influence the next-gen TLXÂ’s design, and lo and behold, here is the next-gen TLX. Of course, Acura has no intentions of letting us see the production car anytime soon, so weÂ’re treated to a heavily cladded prototype in the photos here. Looking at it in profile, the camouflaged car looks a whole lot like the Type S Concept we saw yesterday. The short rear overhang is similar, but the front of the production car looks like it hangs out over the front wheels a little further – it still shares the concept's overall long-hood/short-deck proportions, though. The roof tapers down into the decklid at a shallow angle, similar to the concept car. WeÂ’re sad to see the same quad exhaust isnÂ’t protruding from the rear bumper of this tester. Instead, it gets a dual exhaust with wide, rectangular outlets on both sides. We think the car weÂ’re looking at here is likely a regular TLX, and not the spicy Type S variant most likely seen last year. ThereÂ’s one interior photo our shooter was able to snag, showing a similar infotainment screen as that used in the new RDX, something we fully expect for the production car. That touchpad system is far superior to Acura infotainment systems of the past, but it still isnÂ’t perfect. An analog tachometer is visible off to the left, indicating that the regular TLX trims probably won't introduce a fully digital instrument cluster. Not that we'd expect that; even the new RDX maintains analog gauges in its top spec. However the TLX story plays out, it wonÂ’t hurt if the production car looks just like the well-received Type S Concept. ItÂ’s unclear how long weÂ’ll have to wait to see the car in full, but we'll keep you posted.
