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 is launching an all-out assault on Pikes Peak

  Acura is gunning for multiple trophies at Pikes Peak later this month, sending no less than six vehicles to the famed hillclimb event. The fleet consists of two NSX race cars, two TLX Type S race cars, a TLX Type S pace car, and the 2022 MDX Type S making its first public debut. The all-volunteer team comprising Acura employees will be towing the more potent of the TLX race cars 1,300 miles from its base in Ohio to the Colorado venue with an MDX Type S. While a stock TLX Type S weighs 4,221 pounds, a mass that's pretty close to the 355-horsepower, 354 pound-foot flagship's towing capacity of 5,000, the race car is considerably lighter.  Honda put the TLX Type S on a 600-pound diet, gutting the interior and replacing parts with lightweight components like a carbon fiber hood. Naturally, aerodynamic aids like splitters, canards, and spoilers festoon the race car. On top of that, the 3.0-liter V6 it shares with the big brother MDX Type S has been modified with a with a larger turbo and additional cooling to account for the thin air approaching the 14,000-foot summit. Acura engineer Justin Lumbard will helm the TLX in the Pikes Peak Open Division, in which an Acura TLX GT race car holds the record of 9:24.433, set by Acura race veteran Peter Cunningham in 2019. Meanwhile, chassis engineer and cool-name-haver Jordan Guitar will be piloting the other TLX Type S, a more stock version with only a 300-pound diet. Both cars wear race-modified suspensions and HRE 19-inch 19 x 9.5-inch wheels wrapped in Pirelli slicks. Likewise, the NSX pairs comprise one hard-core racer and one mostly stock car each, allowing Acura to pursue wins in multiple classes. Drivers and brothers James and Nick Robinson are no strangers to Pikes Peak records. James helped Acura clinch the Hybrid Class record with a time of 10:01.913 in an NSX last year, and is now shooting for a Time Attack 1 Division championship. His NSX puts out around 625 horsepower thanks to larger turbos and reprogrammed engine software. A front splitter, large rear wing, 200-pound weight reduction are just some of the race-prep modifications. Meanwhile, Nick holds the front-wheel-drive record, set in 2018 with a first-generation Acura TLX and a time of 10:48.094. This year, Nick is behind the wheel of an NSX that's all stock — aside from safety equipment and race tires — in the hopes of achieving a Time Attack 2 production record attempt.

2019 Honda S2000 roadster rumors swell

Our friends over at Car and Driver have been speculating about a possible S2000 roadster from an unnamed insider source. While there's not much to go on, it certainly squares with a steady drumbeat of sporty car innuendo surrounding the company. Let's briefly connect the dots and see if a Honda S2000 might be on the way by 2018, as the rumor says. The little roadster pictured above? Definitely not what a new S2000 would look like. That's the S660, which is sold in Japan and shares some components with the N-Box and N-One microcars. As we told you last year, after some hints that it would come to the US, Honda's brass decided it was too small. That was disappointing, but probably the right call. On the other hand, Honda finally brought out the 2017 Acura NSX, which may have its flaws but still represents a unique platform that the company spent a great deal of yen building ( in Ohio, by the way). It's that bit that the rumor hinges on: Honda's willingness to develop unique platforms for its sporty models. It'd need that for an S2000 revival, because there's certainly no Honda model that could donate its underpinnings at this moment. Honda execs have been clear that the company is under pressure from dealers over the lack of verve in the company's lineup. American Honda Executive Vice President John Mendel told Automotive News last year that dealers "want anything in the sports car world. They're going, 'Gimme a sports car.' They want a retractable hardtop; they want a high-horsepower $20,000-sports car. Because that's the nature of what they do." Honda is allegedly going to utilize some sunk cost by employing the new Civic Type R's engine in this roadster. That 2.0-liter turbocharged four makes 306 hp in the Civic, and would make slightly less than that in the S2000, according to the rumor. At this stage, these rumors are mostly wishful thinking fanned by the flames of dealer pressure for sporty models. We hope Car and Driver's insider has it right, because the S2000 was a phenomenal car that deserves a follow-up – and Honda deserves more fun cars in its American showrooms.
