Top-10 fastest cars made in USA

Tesla.jpg10. Tesla P90D (155 miles per hour)

Yes, the P90D is limited to a top speed of “just”155 miles per hour, just like a full-size SUV from Mercedes. But unlike other cars in the 155 club (a common top speed for limited cars), the P90D has 762 horsepower and can sprint from zero to 60 in an eye-watering 2.8 seconds. Top speed be damned, the P90D is just plain quick.

GM Content to Take Slow Lane toward “Super Cruise” Autonomous Features


2016 Cadillac CT6It will be difficult—if not impossible—for motorists to relinquish an active role in driving cars equipped with the semi-autonomous Super Cruise feature now being developed by General Motors, the company’s two top leaders said at a Detroit conference. When the feature arrives, sometime in 2017, it will contain components that ensure drivers remain alert and ready to control their cars.

For example, Super Cruise will contain sensors that track drivers’ eye movements. “If we don’t get those signals and feedbacks, we don’t engage,” said Mark Reuss, GM’s executive vice-president. “We take the car and slow it down and call OnStar, for instance.”
In the wake of a fatal crash involving a similar semi-autonomous feature made by Tesla Motors, General Motors executives found themselves in the awkward position of highlighting the limitations of the upcoming feature rather than its functions. But given the widespread concern over Tesla’s implementation of its Autopilot, GM’s cautious decision to delay the arrival of Super Cruise has gained favor. Speaking at the Billington Global Automotive Cybersecurity Summit in Detroit last week, CEO Mary Barra and Reuss both emphasized they consider Super Cruise an advanced driver-assistance feature, not a driver replacement.
“The fundamental premise of the system is not unlike that of an autopilot system in an airplane, where you’re reducing fatigue and you’re increasing the awareness of the driver over a longer period of time,” Reuss said.
Reuss and Barra made it clear that Super Cruise differs from that other Autopilot—the semi-autonomous feature that Tesla Motors added to many of its Model S vehicles via over-the-air updates last fall. While Tesla’s system uses a camera and radar for operation, GM’s Super Cruise also will rely on lidar sensors to map its road environment. That map data will be compared with previous maps of the road to understand discrepancies, according to Reuss. Super Cruise operations will be limited to roads where that mapping has taken place. But what will Super Cruise add?

Clearly, there’s going to be development, and it’s not a technology that eliminates all incidents, but we’re definitely going to be in a safer place. — Mary Barra

GM says it will be capable of following lanes, braking, and controlling speed under certain conditions. A light on the steering wheel will indicate to drivers when the system can be engaged or when a motorist needs to retake control of the vehicle.
Both Super Cruise and Autopilot are semi-autonomous features that are seen in the industry and elsewhere as building blocks on the path toward fully autonomous vehicles, which Reuss said could be ready to hit the road in five to seven years.
Any problems with these interim features could hinder consumer acceptance of self-driving cars. In January, General Motors postponed the debut of Super Cruise on the Cadillac CT6 to continue refining the feature. A spokesperson said the company still intends for Super Cruise to make its debut on the CT6, and Barra said it will launch “next year.” She said Super Cruise is a technology the company has invested “thousands of thousands of man-hours developing and validating.”
Tesla Motors markets Autopilot as a beta technology and requires drivers to agree that they maintain responsibility for the operations of their vehicles. As seen on recent YouTube videos, some drivers have instead treated Autopilot as a fully autonomous technology. Now federal investigators are probing the feature’s role in a fatal crash in Florida that killed Joshua Brown.

As that investigation continues, federal safety regulators are formulating new guidelines for autonomous deployment that might affect the future of Super Cruise, Autopilot, and any number of similar systems other competitors are developing. Transportation Secretary Anthony Foxx said last week that framework should be released by the end of the summer.

“I’m very anxious for the guidelines that are going to be coming out,” Barra said.
Mark Rosekind, administrator of the National Highway Traffic Safety Administration, offered a small glimpse at those guidelines last week, saying the government would not expect autonomous technology to function perfectly and that delaying the deployment of new technology, such as Super Cruise, that improves safety could result in further road fatalities. Barra agreed.

Cadillac has announced full details of its new Carbon Black appearance packages, arriving for the 2017 ATS and CTS lineup.

The upgrade list includes the first-ever Black Chrome grille for V-Series models, along with standard Recaro front seats for the ATS Sedan and Coupe.

The ATS will also receive Black Chrome elements on the rear fascia, with matching side window moldings. After Midnight dark finish wheels and a V-Series spoiler complete the exterior look, while low-gloss carbon trim adorns the Jet Black or Light Platinum interior.

The enhanced CTS features many of the same upgrades brought to its smaller sibling, however the Recaro front seats are available as an upgrade rather than listed among the standard features.

The Carbon Black ATS-V and CTS-V boasts even more carbon-fiber gear including a more aggressive front splitter, hood vent trim, rear diffuser, rocker extension panels and a taller rear spoiler.

Norway council: Tesla owes fines for misstated horsepower numbers


Tesla’s second-biggest market could cost it a lot of money

Tesla owners in Norway — the EV maker’s second-largest market — filed a complaint over the power output of the Model S P85D, and it looks like they may be in line for a $6,000 payday.
The problem stems from Tesla marketing the car as producing 691 hp (467 hp from the rear motor and 224 hp from the front). In dynamometer testing it doesn’t quite match that number, because Tesla came up with their horsepower figure by just adding the output of the front and rear together. Tesla has since changed the way they market their power, reducing the quoted number from 691 hp in the P85D, to 532 hp in the P90D with Ludicrous mode.
However, over 150 P85D owners felt cheated by this horsepower deception and took it up with Norway’s Consumer Council. The council sided with Tesla here, but when the same group took the problem to the Consumer Disputes Commission, they decided in favor of Model S owners. This penalty won’t be cheap for Tesla, since the Model S is actually the best-selling car in Norway. Tax deductions and various other benefits you receive for driving an electric make a Model S half the price of a BMW 7-Series or Porsche Panamera. Tesla could end up being on the hook for well over a million dollars if all the Model S P85D owners collect their payments.

The fight doesn’t appear to be over yet, though: Tesla is still reviewing the decision, and an appeal might be forthcoming.

2017 Cadillac ATS Loses Base Engine, Gains More Feature Content


The 2017 Cadillac ATS sedan will enter U.S. showrooms this summer with one less engine option for consumers to choose from, as the former base 2.5-liter four-cylinder engine is going the way of the dodo. In its stead, the brand’s 272-hp 2.0-liter turbocharged four-cylinder engine will now serve as the the entry-level powertrain, as it currently does in the ATS coupe. A 300-plus-horsepower V-6 remains optional.

With a base price of $35,590, the 2017 Cadillac ATS sedan’s starting price rises by $1380 but also includes such features as Cadillac’s CUE infotainment with an 8.0-inch touchscreen, Apple CarPlay and Android Auto, a Bose surround-sound audio system, and a rearview camera. These features appear on the base Cadillac ATS coupe as well.
Despite the entry-level car’s higher price, Cadillac promises all other ATS trim levels—Luxury, Premium Luxury, and Premium Performance—will offer more feature content at less cost, with Automotive News reporting that 2017 models will be priced between $650 and $1100 lower than their equivalent 2016 counterparts.
It’s no secret that ATS sales have failed to catch fire, and with year-over-year sales of the model down by more than 23 percent through May, clearly something needed to be done to spur interest in Cadillac’s entry-level sports sedan and coupe. Here’s hoping the updates inspire more people to consider a car we really enjoy driving.
