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 doesn't have plans for a new MDX hybrid

Besides an entirely new platform, suspension, and a turbocharged Type S model coming soon, the 2022 Acura MDX is new in another way: it seems to be losing its hybrid trim level. During a media roundtable, Acura's global development lead confirmed that there are no plans for a hybrid version of the new MDX. Part of the reason for the lack of a hybrid for the new MDX is the aforementioned Type S model. The Acura development lead noted that the outgoing MDX Sport Hybrid is the current sporty, high-output version of the crossover. That mantle is now being taken over by the Type S with its turbocharged 3.0-liter V6. The new Type S makes 355 horsepower and 355 pound-feet of torque, which also represents a large power increase over the Sport Hybrid's 321 horsepower and 289 pound-feet. The Type S won't be able to do everything the Sport Hybrid could do, though. While official fuel economy numbers haven't been revealed, we're confident the Type S won't be able to hit the 27 mpg combined of the hybrid. The Sport Hybrid's powertrain was also quite interesting, as it combined its 3.0-liter naturally aspirated V6 with a trio of electric motors. A single motor worked in conjunction with the engine to power the front wheels, and one motor each powered the rear wheels and provided torque vectoring. It was sort of like a backwards NSX. While Acura doesn't have plans for a hybrid right now, it is possible the brand could change its mind. And in an ever electrifying world, it would be surprising if we never saw a hybrid MDX return.

Mid-engine Honda sports car surfaces in EU patent drawings

Based on new patent drawings, Honda clearly isn't done with sports cars. The design you see above was registered and published by the European Union Intellectual Property Office (EUIPO) and was first reported by AutoGuide. The drawings show a rakish, angular sports car design that is very clearly mid-engine. It could almost pass for a Lamborghini. But the name on the design is Honda Motor Company, and aside from the name, it bares a strikingly similar appearance to a mid-engine design found in a Honda patent two years ago. In fact, the only major difference between this car and the older one (seen below) is the lack of a windshield and top. The shape of the lights and the grille, as well as the front fender vent and character lines running from it, are reminiscent of the S660 kei roadster for Japan. The large, angular intakes look more related to the Acura NSX, though. View 6 Photos Unlike the previous patent renderings of the car, this one has an interior, and the inclusion of it may be why the top and windshield are absent. The interior also leads us to believe that this design is for an upcoming concept. The steering wheel is a small, rectangular piece similar to what you would find in an F1 car or Indy car. The seats also look like thin buckets designed to be as sporty and light as possible. A production version would probably have a bit more cushioning and a round wheel. It does look like there is a pushbutton transmission setup in the center console like current Acuras, though. So what does this mean? Honda is clearly still working on this design, and based on some of the more radical design choices for the interior, we're likely looking at a concept car that will show up in the next couple of years. Whether a concept will lead to a production car is tough to say. There's definitely room in Honda's global sports car roster between the S660 and NSX for something in between, and Honda has reported that it's getting pressure from dealers for sporty cars. The exterior design isn't so extreme it couldn't be tweaked for production, either. There have also been rumors that Honda is preparing a mid-engine hybrid sports car with the Type R's turbocharged four-cylinder. Honda also holds a trademark for the name "ZSX," which fits the naming scheme of the NSX and old RSX, but at least in Europe, Honda has held the trademark since 2009. We'll just have to wait and see what Honda does.
