Snapshots from Acura NSX prototype run at Mid-Ohio

Acura's achingly slow showing of the new, hybrid NSX saw yet another step yesterday, as we reported late last week. A powder-blue prototype ran ahead of the open-wheelers at the Honda Indy 200 at the Mid-Ohio Sports Car Course. Why show the NSX Prototype at Mid-Ohio? Honda's Ohio research and development center, which has taken the lead on NSX development, is just 60 miles from the track. And as race sponsor, Honda must have figured it would give the spectators a glimpse of the new supercar it's been teasing for the better part of a decade.
With a planned launch in 2015 (special emphasis on the "planned" part, considering the NSX's history), the NSX Prototype shown here sports graphics that "speak to Acura's intention to go racing with the new NSX." That's great news for fans of endurance racing, although it remains to be seen when a motorsports program for the new NSX will get off the ground.
Take a look at the fresh gallery of images, and be sure to head over to our original Mid-Ohio post for the video footage of the NSX Prototype on track.

Acura confirms more 2016 NSX details

Acura served up a slew of engineering details about the soon-to-launch 2016 NSX. Fittingly, they were explained at a dinner at the SAE International World Congress in Detroit, where morsels about the new Acura supercar were likely gobbled up quicker than the main course. Among the highlights: The NSX will mark Acura's first use of a multimaterial space frame, and it includes high-strength steel and aluminum. This will allow the NSX to hit its weight targets, while maintaining rigidity. The NSX uses a so-called "ablation" technology, which allows the ultra-rigid castings to be used within the car's crush zones. For more details on this, scroll through the press blast below. As expected, the NSX will pack a twin-turbo V6 engine, and Acura confirmed it will displace 3.5 liters. The unit will be mounted amidships and team with hybrid components to increase performance and efficiency. The supercar also features the most advanced evolution of Acura's Super Handling All-Wheel-Drive system, and it's capable of distributing more torque than any other setup the brand has used. The NSX has 10 air-cooled heat exchangers that will cool the powertrain, and the V6 alone will have three radiators. There are also twin intercoolers in the side air intakes that further cool the system. The next generation of the NSX was unveiled in January at the Detroit Auto Show, and production launches this fall in Ohio.

DETROIT, April 23, 2015 – In advance of the market launch of the highly anticipated next generation Acura NSX, the engineers leading the supercar's development shared new technical details and design strategies with the automotive engineering community at the April 22nd SAE Detroit Section dinner, held in conjunction with the SAE 2015 World Congress and Exhibition. Additional information about the team's efforts to achieve a true "New Sports Experience" included details of the NSX's world's first body construction process that helped create a multi-material space frame resulting in class-leading body rigidity, the advanced total airflow management system and an update on NSX's power unit specifications. Ted Klaus, chief engineer and global development leader of the new NSX, introduced key powertrain, body and dynamic performance engineers who shared new product and technical details in their related areas of the development.

2017 Acura NSX First Drive [w/video]

The 2017 Acura NSX is heavy. It outweighs the original 1990 car by more than 800 pounds and is over 300 heavier than a Chevrolet Corvette Z06. The NSX is insanely complicated, with an assist motor between the twin-turbo V6 and the nine-speed dual-clutch transmission, plus two torque-vectoring electric motors at the front axle. And the NSX is expensive. It will probably cost $170,000 when it goes on sale in Spring 2016. Commence trolling. If you hadn't guessed, the new NSX isn't much like the first generation built from 1990 to 2005. But the two cars share a common philosophy. Both are Acura's interpretation of what a modern, everyday supercar should be. Based on the new car, things have changed a lot in the last 25 years. For project leader Ted Klaus, the original NSX was one reason he started working at Honda. At the 1990 Detroit Auto Show, "I sat watching that car for a while. A really long while. Even just looking at that car I could see the deep, advanced, functional beauty." The most difficult thing with the new NSX, says Klaus, is to explain how a heavier and more complicated car can outperform other cars in a way that feels like traditional lightweighting. View 33 Photos This is not the way the NSX was supposed to be at first. The original plan was a transverse-mounted, naturally aspirated engine just like the first car. The NSX has a giant bag of neat tricks, but to understand them takes a lengthy explanation that starts with the Sport Hybrid SH-AWD powertrain. Behind the cockpit is a 75-degree, twin-turbocharged, 3.5-liter V6, made specifically for the NSX. On its own it puts out 500 horsepower and 406 pound-feet of torque. The rest of Honda's lineup uses a 60-degree layout, but the wider angle here lowers the center of gravity. Behind the engine is the rear assist motor, with 47 hp and 100 lb-ft. Hanging off the rear of that is the nine-speed dual-clutch, developed in-house. In between the front wheels is the Twin Motor Unit (TMU), a pair of 36-hp, 54-lb-ft electric motors that add or subtract forces to their respective sides. The Power Drive unit manages the electronics, and sits in the center spine of the car like a traditional prop shaft. A lithium-ion battery pack is behind the pair of seats, on the cold side of the firewall. Total system output is 573 hp and 476 lb-ft. This is not the way the NSX was supposed to be at first. The original plan was a transverse-mounted, naturally aspirated engine just like the first car.
