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 to climb Pikes Peak with Integra Type S and wildly modified NSX

This year marks the 101st anniversary of the Pikes Peak International Hill Climb, one of the oldest motorsports events in the world. As has been the custom for the past 13 years, Acura will head to the Colorado summit with a fleet of specially prepped cars based on production models. This year, their team consists of two new Integras in regular and Type S flavor, a modified NSX Type S, and a TLX Type S pace car. Of the Integras, the HPD-prepped Type S will be the most eye-catching, as it's wrapped in an anime-style livery. It's an extension of the company's "Chiaki's Journey" web series whose second chapter was released to coincide with the Integra Type S's launch. The second installment features the Pikes Peak race as part of its story line.  The real-world Chiaki is Lori Unser, a fourth-generation driver in the Unser racing dynasty. Her father Johnny raced at the Indianapolis 500, and if you count her extended family of Al, Bobby, and Al Jr., the clan has nine Indy championships under its collective belt. The family also has a history of racing at Pikes Peak, with Louis and Joe Unser competing in the hillclimb way back in 1926. In the Time Attack I division Acura is fielding a wild-looking NSX Type S called the Active Aero Study. We prefer its nickname, Yamabiko, which means "echo" in Japanese but is also the name of a spirit from Japanese folklore that lives in the mountains.  The NSX wears an enormous carbon fiber front splitter and rear diffuser, which by the looks of them extend the length of the car by two to three feet. The one-off aero bits include an active aero rear wing that can be electronically moved to reduce drag on high-speed sections of the course, or deployed as an air brake. At the same time, enough has been stripped out to reduce weight by 200 pounds. More powerful turbos have been fitted to the twin-turbo V6 and the engine software re-written, but Acura did not reveal how much over the stock Type S's 600 horsepower Yamabiko's output might be. The NSX was built specifically to tackle the hillclimb by Crazy New, the skunkworks team of Honda employees that brought us the 800-horsepower CR-V Hybrid. It'll be driven by Honda engineer James Robinson, who holds the current Hybrid class record of 10:01.913, which he set with an NSX in 2020. With Yokohama Tires' trademark Advan black and red livery and lightweight HRE forged wheels wrapped in Advan A005s, it certainly looks the part of a purpose-built Pikes Peak racer.
