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:

Rumors abound over Honda's mid-engined 'Small NSX'

The "baby NSX" lately in the news has been in Honda's idea cloud since before the 2008 global financial rift. The company called it the "Small NSX" and reports said it "will really be a scaled-back version" of Acura's exotic, including the mid-engine layout and a variation of the hybrid SH-AWD. It even had a price: $50,000 to $60,000. So more than seven years on, when a series of patent images materialize for what looks like an NSX-inspired Honda sports car, it doesn't prove anything, but it fits. Motoring reports that the Small NSX will sit at the top of a lineup of three mid-engined sports cars intended for the Honda brand - but note that Motoring is based in Australia, where our Acura NSX is sold as a Honda. This Small NSX would be a "radical replacement" for the Honda S2000 that ended production in 2009. Beneath it will be a global version of the S660 roadster that could come here as an S1000 with 125 horsepower. The Civic Type R and a much sportier, reimagined CR-Z will put some long forgotten handling chops at other price points in the model mix. Motoring's sources say the Small NSX design work is, "for all intents and purposes, completed." The consistent rumor regarding engine is the 306-hp 2.0-liter turbo VTEC used in the Civic Type R. One electric motor will be in back to help move the rear wheels, two electric motors will hang on the front axle. Overall power output is put at around 400 hp, with 330 hp of that coming from the ICE, working through a nine-speed dual-clutch transmission. An aluminum frame with aluminum and carbon fiber parts will discourage heft, the final product at aiming at a weight under 3,100 pounds. Its price should be competitive with its intended target, the Porsche Cayman. The 2018 Detroit Auto Show is where we might see it, before it goes into production later that year at Honda's Performance Manufacturing Center in Marysville, OH.
