Acura NSX GT3 data 'will inform future iterations' of the street car

Motorsports programs exist to drive innovation in road vehicles, and that's precisely what's happening at Honda. Acura NSX development boss Nick Robinson told Autocar that the company's work on the GT3 racing variant is directly informing future development on the road car. "In North America, we've just unveiled the GT3 version of the car, and the development team of the street car has had some involvement in its development," Robinson said. "What works well on the track will inform future iterations and updates of the street car and vice versa." But Honda is a big company that does more than build cars. Robinson paid tribute to the impact his employer's well-known motorcycle program had on the NSX. Apparently, building stuff like the CBR helped Honda with the NSX's complicated packaging. "For many years our motorcycle development teams have strived to ensure the optimum centralization of mass, ensuring the lowest possible center of gravity," Robinson told Autocar. "This leads to the best possible yaw response." Is this all a sign that a long-rumored lighter, faster NSX, potentially wearing the vaunted Type R badge, will be especially track-focused? Maybe. Robinson's comments indicate that the company is doing something with the mountains of data it collects running a GT3 program. While a pure road-focused NSX-R successor seems like it'd be a waste of that data, an NSX-based rival to the Porsche 911 GT3 RS might make a lot more sense.

Acura NSX will use Cosworth block, plus other neat tidbits

The blue NSX you see here was built just two weeks ago. Prototype number six, it rolled off Acura's newest assembly line in Ohio and was rushed out to the Monterey peninsula for various car week activities. We had a chance to sit down with several members of the NSX team to discuss the car, the long road from concept to production, and some interesting details. Below are some choice bits from our conversations. Acura is pretty proud of the fact that NSX version 2.0 was designed and is being built in the US. The new assembly line, called the Performance Manufacturing Center, is in Honda's hometown of Marysville, Ohio. While the line is brand new, the building has seen many uses over its lifetime, most recently as a warehouse facility. PMC staff numbers about 100, with 60 technical and 40 non-technical associates. The car uses parts sourced globally, and one of those sources is Cosworth. The engine blocks and heads come from the English firm and get assembled into twin-turbo powerhouses at Honda's nearby Anna, Ohio, engine plant. The Cosworth name is rarely associated with a bad engine, so we were geeked to hear the NSX's 550-plus-horsepower hybrid powertrain has good genes. Acura hasn't decided how many cars will come to the US each year, but supplies will be limited. We're told there is a total figure for global sales – basically anywhere Honda and Acura vehicles are sold – but they're not ready to divulge that number. Dealer allocation is also yet to be sorted out, although we're told that any dealer that has the necessary tools and equipment to service the new NSX will be able to sell them. Acura currently has 272 US dealers. The switch from the transverse engine originally planned to a longitudinal twin-turbo engine threw everyone involved for a loop. The designers had to lengthen their nearly finalized design, and the engineers working on the production process had to revise or redo much of their work. Though we've been waiting a while for the car since the concept first surfaced in 2012, it's pretty amazing to think that the car was engineered one and a half times and a new factory was built in about three years. But yeah, it's delayed, with series production now set to commence in the spring of 2016. One result of the switch to a longitudinal engine is a transmission hump in the cargo area aft of the engine. The hold is still sized to fit a bag of golf clubs, though it will be a tight fit.

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.
