Acura teases new performance EV for Monterey

Acura is headed to Monterey Car Week with what it's calling a "next generation" performance concept. While Honda's premium subsidiary offered up no details about the car itself, we were offered the above teaser photo. Acura says it will be a "segment defying" sport utility vehicle, but what we're seeing here looks awfully trunk-like. From this perspective, it's really anybody's guess, but one thing is obvious: Whatever this thing is, it's no mere ZDX offshoot. Here's Acura's announcement in its entirety, should you be interested in parsing it yourself: "Acura will once again take center stage during Monterey Car Week for the world debut of an exciting new concept vehicle. A segment defying sport utility vehicle, the dynamically styled concept previews the performance brand's next generation all-electric model – the first to be built in Ohio on the company's new dedicated EV platform." The most significant takeaway here is that last bit. Being on a new dedicated platform means that this car has nothing to do with the current Honda-Acura EV offerings, both of which are based on architecture shared with General Motors. Honda has already announced that it will migrate its mainstream EVs to a new, in-house "0 Series" platform in the coming years, with an initial focus on passenger vehicles followed by expansion into people-mover territory. We've yet to hear anything concrete about a parallel program at Acura, so this could very well be the first breadcrumbs to that effect.  For now, that's all Acura has to offer. Keep your ears to the ground during Car Week for more. 

Honda S2000, Acura RSX recalled over brake boosters

Honda has announced a recall that affects two of our favorite, dearly departed cars from the brand's portfolio: the S2000 roadster and Acura RSX coupe. A total of 5,239 S2000 models from the 2006 and 2007 model years are affected by this problem, as are 13,113 2006 Acura RSX models.
"A production error may have allowed brake booster components to be produced outside of the original specifications, potentially causing decreased brake assistance over time, which could increase the risk of a crash," American Honda said in a press release. Thus, dealerships will inspect and, if necessary, replace the brake booster setups in these vehicles, free of charge.
No crashes or injuries have been reported in relation to this brake problem. Honda says the problem was discovered during warranty claim analysis.

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.
