Acura NSX GT3 to make public debut this week at Mid-Ohio

The new Acura NSX had a very long and very public gestation period. The car went through a number of redesigns and revisions, all while enthusiasts watched and waited. With the production version just now ramping up for customer deliveries, Acura revealed that it was working on a race car for FIA GT3 homologation. While the car was shown in New York, no one outside of Honda has seen it testing on track. This week, the NSX GT3 will make its public testing debut at Mid-Ohio Sports Car Course ahead of the Pirelli World Challenge and IndyCar races. View 13 Photos While the car will be on track during testing and practice sessions, it won't actually be competing with the rest of the field. The car is still in the testing phase and won't be fully FIA approved until at least September. Acura is confident that the car will make its racing debut in 2017. The company also made it clear that this is not the final version of the car and that things like aero and engine tuning are still being worked out. Until now, the NSX GT3 has only tested at private events in Europe, Japan and the US. This week, the NSX GT3 will be piloted by Dutch racing driver Peter Kox. Kox drives for RealTime Racing, a team that currently campaigns an Acura TLX GT. This week's car will be the primary tester, though if something goes sideways there are multiple backup cars. The NSX GT3 differs in a number of ways from the road car, most notably its lack of hybrid all-wheel drive system. The NSX GT3 uses the same twin-turbocharged V6 as the road car, but sends all the power through the rear wheels. It also uses the same space frame as the road car. While the road going version receives final assembly in Honda's Ohio factory, final touches to the GT3 car are done elsewhere. Although the car will only be testing on Thursday and Friday, it will be on display all weekend in the paddock.

2017 Acura NSX | 2017 Autoblog Technology of the Year Finalist

Like its iconic predecessor, the second-generation Acura NSX blazes trails. The old NSX proved that you could get reliability and daily use from an exotic car, and subsequently changed the automotive world. Acura's engineers pushed in a new direction for the prodigal successor: technology. And so the new NSX sets a new bar in the way technology is used to achieve speed. The highlight here is the Sport Hybrid SH-AWD system, which supplements the 500-horsepower twin-turbo V6 with three electric motors, making 573 peak ponies. The two front motors each act on a front wheel, doing all kinds of tricks to help the car corner faster, brake harder, and accelerate like the proverbial cannon shot. They help make the NSX more stable at high speed, and let you sneak up on unsuspecting video producers at low speed. Then there's the third motor sandwiched between the engine and nine-speed transmission, which never lets a shift go by without filling in the milliseconds with velvety torque. If the all-wheel-drive hybrid supercar sounds familiar, yes, Porsche did something similar with the 918 Spyder. But even when you load the options on the NSX (try not to, we dare you), it's never more than a fifth the price of the Porsche. Then there are the little details, like a new form of casting Honda engineers developed for the NSX's crash structure. Or the three-dimensional bend to the A-pillar and roof rail that makes it less obstructive to the driver and also stronger. Even the Marysville, Ohio factory gets some credit here, with 12 patents filed relating to the assembly process. There's only so much a driver can do with two hands and two feet. The NSX takes your inputs and figures out how to maximize the contribution from each individual wheel. This is a car that harnesses all the greatness of technology to change what's possible in a sports car.Related Video: 2017 Acura NSX | First Drive

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.
