Acura NSX prototype gets back on track

Developing a new vehicle is not without its complications, we're sure, but usually things follow a fairly predictable progression: you develop a prototype, you test it, test it and test it again, then you put it into production. What you don't expect is that your prototype will burn to the ground, but that's what famously happened to the NSX which Honda engineers were testing a few months ago.
Fortunately, the Acura NSX prototype is back on track, both literally and figuratively, as you can see from this latest batch of spy shots snapped at the Nürburgring. This camouflaged prototype looks pretty much the same as the last one, only, you know... less crispy. Which is to say, it looks pretty much ready to hit showrooms.
The naysayers may point out that Honda chose colder and damper weather to put the NSX back into testing - thereby mitigating the risk of another fire - but we're sure the Japanese automaker has been working hard to fix the flammability issues, whatever may have caused them, over the past few months. At least, we hope they have.

2017 Acura MDX Sport Hybrid goes on sale in April for $52,935

If you like the hybrid tech of the Acura NSX, but don't need a six-figure, 191-mph supercar as your daily driver, you might enjoy the extra room of the Acura MDX Sport Hybrid. It uses the same SH-AWD system with three electric motors as its racier stablemate – and puts a naturally aspirated 3.0-liter V6 up front – but seats up to seven people. It goes on sale in early April, and Acura has announced a starting MSRP of $52,935. The MDX Sport Hybrid starts at $7,910 higher than the base, front-wheel-drive MDX, but only $1,500 more than the comparably equipped, non-hybrid MDX SH-AWD. It offers 31 more ponies, for a total of 321 peak horsepower and of 289 pound-feet of torque. It's less expensive than the other Acura to use the Sport Hybrid system, the RLX sedan, which starts at $59,950. (That car incurs a price premium of $5,500 over its P-AWS-equipped FWD base model; there's no non-hybrid AWD RLX.) The MDX Sport Hybrid gets an EPA-rated 26 mpg city, 27 highway, and 27 combined. Compared to the conventional MDX SH-AWD's 18/26/21 mpg rating, its biggest fuel economy gains are to be found in city driving. The Sport Hybrid's figures are even slightly better than the 25/26/26 mpg Acura expected when the car debuted in New York last year. The MDX Sport Hybrid should be fairly entertaining to drive, too, at least for a utility vehicle. It's Acura's most powerful SUV to date, and it offers four driving modes: Comfort, Normal, Sport, and Sport+. A seven-speed dual-clutch transmission handles the gear changes, but the driver can take control via a pair of paddles on the back of the steering wheel. The SH-AWD system's torque vectoring feature promises to help make the MDX proficient in the twisty bits, too. Related Video:

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.
