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.

Honda finds new Green Path to reduce CO2 emissions

In the wake of the Volkswagen diesel scandal, it's impossible to hear an automaker talk about its overall environmental efforts and not think to yourself, "for real?" Still, we're willing to listen. And Honda representatives gave it their best shot yesterday in Marysville, OH as they introduced a small group of journalist to the company's expanded initiative aimed at cutting CO2 emissions and the total life-cycle environmental impact of Honda products. Called Green Path, the initiative now includes a $210-million expansion at Honda's Marysville, OH manufacturing plant to install a better, cleaner paint shop. Speaking at the facility yesterday, Honda representatives said that the plant room is not only better for the environment (it uses limestone dust instead of water to capture paint particles, for example, reducing water usage by about 2 million gallons annually. Overall, the new paint shop will have 60 percent less VOC emissions and reduce CO2 emissions by 18 percent), it also makes the cars look better. That's whey the two-step temperature curing process will initially only be used on Acuras to differentiate them from the competition. Honda will fire up trials in late 2017. There's more to Green Path than the new paint show, of course. The company wants to reduce - in some cases eliminate - what it calls substances of concern (SOCs), things like lead and mercury. There are also new wind turbines in Ohio to supply power to Honda plants, the Environmental Leadership Program for independent dealerships to make their own green moves, and swapping out fluorescent light bulbs for LEDs, among other efforts. In the Marysville Auto Plant, for example, the Assembly department has over 10,000 task light bulbs. The fluorescent ones used to need to be replaced every three years, but the new LEDs have a life span of 16 years. Honda says that calculating up the impact of all of these little changes will remove an average of 3.822 kilograms of CO2 from the production tally of each car it makes. The company's stated goal is to reduce its total greenhouse gas emissions by 50 percent (compared to 2000 levels) by 2050. You can find out more in Honda's press release and video, below.

The original Acura NSX: Development history and driving the icon

The original NSX, introduced in production form in 1990 by Honda and to the United States market under the Acura brand in 1991, is now officially 25 plus years old. Generations of car enthusiasts grew to love the original NSX over the 15 years it was in production and beyond, but as an fan and owner, I think it's important to fully realize just how monumental a shift the introduction of the NSX was in the art of making cars. So, retold 25 years later, this is the abridged story of the NSX, Honda's supercar. The Idea The NSX was an extremely risky project for Honda, a company that in the late 1980's was nowhere near the corporate juggernaut that it is today. Honda's eponymous founder, Soichiro Honda, was still involved in decision-making at the company during this time under the role of "Supreme Advisor," and it is debatable whether the NSX project in its infancy would have gone forward at all had he not still been pushing the company towards the spirit of technical achievement it had been known for in the prior decades. Mr. Honda was still so involved during this period, in fact, that when the first batch of 300 production NSXs were made with a version of the Acura badge he didn't like, he ordered all of the cars stopped at port in the USA, the new badges applied, and the offending incorrect badges sent back to Japan to be systematically destroyed. This was clearly a man who paid attention to the details, but I digress. Honda as a company devoted $140 million dollars to the NSX project ($250 million in today's money), half of which would go to developing the car, and the remainder of which would go to building a new state-of-the-art factory to assemble it. Honda's own goals for the NSX were actually exactly as most media stories portray the car today: to build a bona-fide exotic supercar, but one without the ergonomic and reliability penalties associated with that type of car. They didn't want to sacrifice the needs of the driver to the supposed demands of performance, demands that they felt didn't have to be there in making a truly top-level performance machine. The R&D team wanted a car that could hang with heavyweight exotics in a straight line, play with smaller and more lightweight sports cars in the curves, and cruise in serenity on the freeway. Essentially, they wanted it all, and the brief was to have a car that could do everything without compromise.
