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.

Singer Porsche, Koenigsegg, NSX: Leno's life doesn't suck

Jay Leno had quite a productive trip this year during Monterey Car Week. Not only did he get to pal around with Ian Callum and check out the Pebble Beach Concours d'Elegance, but the denim-clad comedian also headed to The Quail to talk to some prominent figures in the modern sports car scene. Capping off the fun, he got to take a drive in a Mercedes-AMG GT S, too Perhaps the highlight of this show is a nearly 10-minute interview with Christian von Koenigsegg. The founder of the Swedish hypercar company digs deep into the Agera One:1's engineering details, relating interesting facts about the aerodynamics and transmission. In addition, Leno chats with Rob Dickenson of Singer about its newly reimagined Porsche 911 Targa, and he gets the latest scoop on the Acura NSX's progress from newly promoted Acura Vice President and General Manager Jon Ikeda. If you like hearing about the nuts and bolts of sports car development, then this video can't be missed. Of course, we were there at Monterey, too, and we pointed our own cameras at some of the amazing machinery, both vintage and modern, at all the various car-focused events of the week. Take a look back at some of our own cool footage in the videos below. Related Video:

2021 Acura TLX to revive Type S, get turbocharged V6

The 2021 Acura TLX will revive the sporty Type S model after a 10-year moratorium, and this time around, it's getting a turbocharged V6, further setting it apart from other sedans in the Honda corporate family.  Acura says the new TLX will draw heavily upon the styling shown on two of its recent concepts: the Precision, which was shown in 2016, and the Type S, which was shown last year. The evolution of the styling is obvious even from Acura's darkened teaser image, which depicts a slightly more curvaceous take on 2019's Type S while retaining most of the same key design elements, including the quad-outlet exhaust and pronounced underbody diffuser. Acura's announcement was otherwise very light on details, saying only that the 2021 TLX will be "...the quickest, best-handling and most well-appointed sport sedan in Acura history, with the Type S being the model’s performance pinnacle." Apart from the displacement (3.0 liters), we don't yet know anything about the turbocharged V6 that will be utilized in the Type S. It will be unique to this model at launch, however Acura's announcement describes this as the "first" implementation of this engine, implying that it will likely make its way under the hood of other Acura models down the line.  Autoblog reached out to inquire as to whether a manual transmission is under consideration for the Type S model; an Acura representative said only that the company is not yet ready to get into specifics on the 2021 TLX's features.  Acura will debut the new TLX online at its dedicated microsite on May 28 at 10 a.m. PDT (1 p.m. EDT).
