2017 Acura NSX: Hypercar technology at a supercar price

This has been a very long time coming, a long time waiting for some proper seat time in the successor to one of the most important sportscars of the '90s -- and of the early '00s, for that matter. It's the new 2017 NSX, thoroughly modernized and precision-engineered to an incredible degree. In fact, some might say over-engineered with its four-motor hybrid system, electronic all-wheel drive and nine-speed dual-clutch transmission. That's a lot of moving pieces, but only one thing matters: How does it feel to drive?

The answer to that question is: "Very well indeed." But, before we delve into the necessary driving impressions, let's take a moment to discuss just what it is that makes this thing go.

The details

Though the NSX is far from a traditional looking car, its powertrain is even less-so. The original NSX was powered by a mid-mounted V-6 that, at its peak, put 290 horsepower to the rear wheels through a six-speed manual transmission. The new NSX also has a V-6 somewhere in the middle, but that's about where the similarities end.

The new motor is 3.5 liters, twin-turbocharged to make an even 500 horsepower and 406 pound-feet of torque. That's a huge bump over the original -- but not enough for Honda's engineers. They've also grafted on a small electric motor onto that V-6, then paired that with two more electric motors up on the front axle. Yes, that's four total sources of oomph (one internal combustion, three electric) with a combined power output of 573 hp and 476 ft-lbs.

Do the math and you'll see that's basically twice the power of the original in a 3,800-pound package. Yes, it has all-wheel drive, but the vast majority of that drive is restricted to the rear wheels. So, too, the car has a strong rearward weight bias: 58 percent on the back axle.

Power gets to those rear wheels via a nine-speed, dual-clutch gearbox and is modulated across the axle with a proper, mechanical limited-slip differential. Suspension is adaptive, magnetorheological damping able to be toggled into one of two modes, one for comfort, the other for somewhat less comfort.

My first full day in the car would start out in the less-comfortable option.

On the track

Thermal Springs was the venue, situated just outside Palm Springs, California. It's a tight course, with a series of orderly turns that make the most of the available real estate. Thanks to a longish back straight I was quickly able to get a feel for the (optional) carbon ceramic brakes, which did not disappoint despite temperatures hovering in the mid-90s. Initial bite is strong and clean, unlike most hybrids I've driven, and brake pedal feel stayed firm -- although, given the car's brake-by-wire system, that feeling is largely synthetic in nature.

Steering, too, is firm and quick, so quick that you can do an entire lap without your hands leaving 9 and 3 on the wheel. Not a fan of shuffle-steering? This is the car for you. However, after a few sessions I couldn't help but feel like the steering was too firm, as if the car were resisting my inputs rather than assisting.

Steering weight is one of the many parameters the car modifies as you cycle through the four driving modes: Quiet, Sport, Sport+ and Track. On Track you get maximum power and the most liberal interpretation of stability control, as well as the stiffest suspension and the most firm steering. Unfortunately, unlike the simpler (and far less expensive) BMW M4, in the NSX you cannot select individual parameters to create a custom driving mode. So, there's no way to get maximum power and handling from the car without also selecting the firmest steering. That's a little disappointing.

Mercedes-AMG heaps on more performance frosting with GLC43



When it was called the GLK-Class, Mercedes chose not to give it a high-performance AMG trim. Now that this compact crossover has been redesigned and renamed the GLC-Class, that decision has been reversed, and the result is the 2017 Mercedes-AMG GLC43, debuting at the New York International Auto Show.

Meant to slot in above the base GLC300, the GLC43 follows the same formula that every other -43 has up to this point -- give it more power, slightly more aggressive looks and plenty of AMG badging. It's even got the same power output from its 3.0-liter, turbocharged six-cylinder engine as two other models -- 362 horsepower and 384 pound-feet of torque.

Whereas the GLC300 is available in both rear-wheel and all-wheel drive flavors, the GLC43 is AWD-only. Its 4Matic system even shares the same rear bias as the C43 Coupe -- 31 percent front, 69 percent rear (heh). Adjustable sport-tuned air suspension is also standard on the GLC43 -- just like it is on the E43.

AMG-specific bits abound, inside and out. It's got larger inlets and a "diamond" style grille up front, quad tailpipes out back, AMG-specific wheels, larger brakes, a sportier steering wheel and other AMG-specific interior elements. Just like -- you guessed it -- every other -43.

Mercedes' decision to shoehorn this motor into anything with a three-pointed star is commendable, but it's all starting to melt together into one congealed mass. It's almost like I've written damn near the same story already. Oh, wait, I have. Thrice. Over the course of a single winter. At least the E43 had a different horsepower figure.

Toyota teases glowing new Prius ahead of New York Auto Show



One of the bigger announcements at the New York International Auto Show won't be a trillion-horsepower hypercar -- it'll be a sedate, environmentally friendly Prius of some sort. Not every piece of big news has to involve going 200 mph, after all.

We're about a fortnight away from New York, and Toyota released a teaser to build some hype around "the next mechanical marvel in the Prius lineup," or so sayeth the three lines of text accompanying said teaser image.

Details are incredibly scant, but from the teaser's silhouette, we can see a set of wraparound LED taillights that look just a bit different than those on the current Prius hatchback. Automotive News believes it's a new plug-in hybrid variant, but anything is possible.

Except, of course, a trillion-horsepower Prius hypercar.

Uber tests secret safety hotline for passengers in trouble

There's a secret way to get in touch with Uber in an emergency.

Since late last fall, Uber has been testing a critical response hotline in the 22 cities across the US for passengers or drivers to call in an emergency.

Riders or drivers who dial 800-353-8237 (UBER) will be put directly in touch with a customer support representative on the phone. If it's a true emergency, the call will be transferred to 911.

The secret safety hotline comes to light after an Uber driver allegedly shot eight people, six fatally.

In the case of the Kalamazoo, Michigan, shooting, an Uber passenger called 911 to alert them to the driver and filed a written complaint in Uber’s system.

While the written complaint wasn’t immediately classified as violent or urgent, the option of a hotline could have theoretically led the passenger to place a call to Uber, much like they had already done to 911.

The hotline gives the passenger the power to determine what is critical and not just rely on Uber’s system as it stands today.

Uber believes that 911 is the best option for passengers or drivers to call in an emergency.

"In the United States, 911 is the panic button and it's the panic button that we want people to use," Uber's Chief Security Officer Joe Sullivan said in a press conference following the shootings. "It's the panic button that law enforcement wants people to use. And we don't want to try and replace that."

The pilot program debuted in these 22 cities simply added an option in the Help menu. When looking to report an incident, riders or drivers would click report an issue before seeing an option for the Critical Safety Response Line.

For those not in the pilot zone, including Kalamazoo, the number to contact Uber isn't shown in the app at all.

In the aftermath of the shooting, Uber did not acknowledge the 4-month-old safety hotline, despite news site Quartz reporting that they had tried to get in touch. On Wednesday, Uber told Inc that it didn't have a national driver hotline, although later clarified its statement to acknowledge this one that's been in testing.

While it's still considered a "pilot", the number can be dialed by anyone in trouble — whether it's readily available in your app or not. During this trial period, Uber has trained staff in Chicago and Phoenix to handle the influx. The hotline, though, is only to be used for emergency safety situations, like someone leaving behind an insulin pump in the car, versus someone forgetting a jacket or complaining about a long route.

"We are always looking for ways to improve communication with riders and drivers," Uber told Business Insider. "In select U.S. cities, we have a pilot program where riders and drivers can call an Uber support representative directly for assistance with an urgent situation after a trip."

General Motors buys self-driving-car software company



General Motors (GM) said Friday it has turbocharged its efforts to win the self-driving-car race with an acquisition.

The automaker — which is competing against tech giants Google and Apple in the race, not to mention other car companies — said it had purchased San Francisco-based Cruise Automation, a software company dedicated entirely to self-driving car technology.

The Detroit-based manufacturer declined to say how much it paid for the startup, which has backing from Silicon Valley venture investors Y Combinator and Signia Venture Partners.

“Fully autonomous vehicles can bring our customers enormous benefits in terms of greater convenience, lower cost and improved safety for their daily mobility needs,” GM President Dan Ammann said in a statement.

The deal carves out a new lane GM in California's burgeoning self-driving technology sector, where rivals Ford Motor, Tesla, Toyota and others are also operating.

GM CEO Mary Barra has vowed to keep the automaker ahead in the self-driving car race, acknowledging that the company must be agile and willing to adapt its business model to survive the coming revolution in the auto industry.

The company recently invested $500 million in ride-sharing firm Lyft with plans to eventually introduce a fleet of autonomous vehicles. GM is already testing self-driving versions of the Chevrolet Volt semi-electric vehicle on its sprawling Tech Center campus in Warren, Mich. The company also plans to introduce automated technology that allows a new Cadillac to steer itself on the highway later this year.

Cruise Automation will operate as an independent, San Francisco-based unit within GM's recently formed Autonomous Vehicle Development Team, led by Doug Parks, one of Barra's long-time confidants.

GM expects to close the deal in the second quarter.

“GM's commitment to autonomous vehicles is inspiring, deliberate, and completely in line with our vision to make transportation safer and more accessible,” said Kyle Vogt, founder of Cruise Automation. “We are excited to be partnering with GM and believe this is a ground-breaking and necessary step toward rapidly commercializing autonomous vehicle technology.”

Of course, the race is far from over. GM global product chief Mark Reuss said the company plans "to invest significantly" in Cruise's team.

China's electric cars sales to double in 2016



China's production and sale of electric cars will more than double this year, the industry minister said on Sunday.

More than 300,000 electric cars were sold in China last year, Miao Wei, the head of the Ministry of Industry and Information Technology told reporters on the sidelines of the annual meeting of parliament on Sunday.

The reliability, mileage and lifespan of electric batteries needs improvement and China needs to speed up the installation of electric car charging stations, Miao said.

Google to urge Congress to help get self-driving cars on roads



The head of Alphabet Inc's (GOOGL.O) Google self-driving car program will urge the U.S. Congress on Tuesday to grant national auto safety regulators new authority to speed the introduction of self-driving cars on American roads.

Chris Urmson, director of Google's self-driving cars program, will tell the Senate Commerce Committee that legislators should grant new authority to the U.S. Transportation Department to help get fully autonomous vehicles on the road, according to his prepared testimony, which was reviewed by Reuters.

"We propose that Congress move swiftly to provide the secretary of transportation with new authority to approve life­saving safety innovations. This new authority would permit the deployment of innovative safety technologies that meet or exceed the level of safety required by existing federal standards, while ensuring a prompt and transparent process," according to the prepared testimony.

Major automakers and technology companies are racing to develop and sell vehicles that can drive themselves, but have complained that state and federal safety rules are impeding testing and ultimate deployment of such vehicles. California in December proposed draft rules that would bar autonomous vehicles without human controls and a licensed driver.

Google was disappointed by California's action. "If every state is left to go its own way without a unified approach, operating self-driving cars across state boundaries would be an unworkable situation and one that will significantly hinder... the eventual deployment of autonomous vehicles," Urmson's testimony says.

Urmson's testimony says many federal safety rules would not be needed with fully autonomous vehicles, like a rear-view mirror requirement.

In January, the U.S. National Highway Traffic Safety Administration (NHTSA) said it may waive some vehicle safety rules to allow more driverless cars to operate on U.S. roads as part of a broader effort to speed up development of self-driving vehicles.

NHTSA said Friday in a report there are significant legal hurdles to allowing fully autonomous vehicles without steering wheels.

NHTSA will write guidelines for self-driving cars within six months, Transportation Secretary Anthony Foxx said in January. The agency last month said the artificial intelligence system piloting a self-driving Google car could be considered the driver under federal law.

Google wants to offer fully autonomous vehicles for use on U.S. roads "soon."

But it had a recent setback. One of its self-driving cars struck a municipal bus in California on Feb. 14. Google said it made changes to its software after the crash to avoid future incidents.
