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 NSX GT3 racecar bares all in raw carbon

Acura slowly and dramatically revealed the NSX over a period of years. There were previews, concepts, and lots of teases before Acura finally showed us the whole thing. It's a different story for the racecar. And today, the wraps come off the FIA GT3-spec NSX to show all of its bare-carbon glory. The NSX GT3 strips away more than just the paint from the standard road car. The racecar comes sans hybrid system, meaning all the power from the twin-turbocharged 3.5-liter V6 is sent solely to the rear wheels. Modifications to the body include a large rear wing, underbody diffuser, and bigger hood vents for engine cooling. While the hybrid system may be gone, the NSX GT3 uses the same block, heads, valvetrain, crankshaft, pistons, and dry sump lubrication system as the road car. Power is sent through a six-speed sequential gearbox instead of the road car's nine-speed. The NSX GT3 will be built alongside the street version in Ohio. Honda engineers in Japan and North America shared in the development. Final GT3 homologation will be completed by the company's Honda Performance Division in Santa Clarita, CA. Related video:

The new Acura Integra was never meant to be a retro car

The new Acura Integra Prototype was never supposed to be a retro or nostalgic design process. It would be easy to assume it was, as Acura’s messaging leading up to the big reveal leaned heavily on the Integra nameplate's heritage. From the model name embossed in the bumpers, to videos of shifting the older modelÂ’s manual transmissions, Acura yanked fairly hard on our heartstrings. And then the cover came off last week, and while there are very subtle cues hinting at old Integras here and there, the new car doesnÂ’t look much like the old ones at all. Unlike designers of the new retro-tastic Nissan Z and Ford Bronco, Acura decided to create something altogether new and different. “So, admittedly, when we started planning this car, it was never to create a retro Integra,” Acura product planner, Jonathan Rivers, told Autoblog. “We actually looked at it from the viewpoint of say, if the Integra had never left the lineup, how would it have evolved? How would it have changed over the years? We think this is the result of that.” There was never going to be a two-door coupe model, because as Rivers points out to us, coupes just don't sell these days. However, sportbacks are popular — just look at the sheer number of them coming from Germany these days — and it suits the customers Acura is trying to capture with the Integra. “The target customer is a millennial with an active lifestyle, so they need space for their gear but they also want to have a great car to hit the canyon roads with every now and then,” Rivers says. “Once again, over the generations, the Integra is just that.” For any naysayers throwing their hands up about the Integra seemingly being a fancy Civic, we possess two points of refutation. One, thatÂ’s exactly what the Integra has always been. It was literally badged and sold as a Honda in many other countries, and its bones have always been Civic-based. ThatÂ’s the IntegraÂ’s history, and while Acura doesnÂ’t officially come out and say so, itÂ’s most certainly the same today. On the design front, maybe you think the photos make it look a little too close to the new 11th-gen Civic Hatchback? Well, pictures on the internet donÂ’t always tell the full story of a car design. “None of the sheetmetal is shared with either the four-door or the five-door Civic,” Rivers explains.
