Cadillac tops Tesla in Consumer Reports semi-automated driving test

General Motors' Cadillac outscored Tesla in a new ranking of partially automated driving systems tested by Consumer Reports and released on Thursday. The highly influential nonprofit organization, which tests and rates a variety of consumer products from appliances to vehicles, said it compared Cadillac's Super Cruise and Tesla's Autopilot with similar systems from Nissan and Volvo. Nissan's ProPilot Assist was ranked third and Volvo's Pilot Assist fourth. Consumer Reports said it has been testing partially automated driving systems for several years but elected to conduct a formal study intended for publication, because "we are at a tipping point where they are now going mainstream," according to Jake Fisher, director of auto testing. The organization said its tests, conducted on a private track and on public roads in Connecticut, were designed to measure the systems' ability to automatically control steering and speed in certain situations, while helping drivers pay attention and regain manual control of the vehicle when required. CR noted that any of these systems can increase driving risk if used in inappropriate situations, or if drivers become inattentive or over-reliant on them. While they can help relieve driver stress and fatigue, Consumer Reports said, the partially automated systems are "not intended to be self-driving features." The systems typically use cameras, radar and other sensors, as well as mapping data, to monitor location and traffic conditions and help keep a vehicle centered in the lane at a safe distance behind other cars. Each system has limitations. Cadillac's Super Cruise, for instance, only functions on divided highways that have been mapped by GM. In contrast, Tesla's Autopilot can be used even on small, curvy roads with poor lane markings, but "operates erratically in those situations," Consumer Reports said.The organization tested Super Cruise on the Cadillac CT6; Autopilot on the Tesla Model 3, Model X and Model S; ProPilot Assist on the Nissan Leaf and Infiniti QX50; and Pilot Assist on the Volvo XC40 and XC60. Consumer Reports said Cadillac's Super Cruise did "the best job of balancing high-tech capabilities with ensuring the car is operated safely and the driver is paying attention." Tesla's Autopilot was cited for its capability and ease of use, while Nissan's ProPilot Assist did a better job than Autopilot or Volvo's Pilot Assist in keeping drivers engaged.

Recharge Wrap-up: Tesla hiring new sales executives, A123 focuses on starter batteries

A123 Systems is shifting more of its focus to lithium-ion starter batteries for cars with stop-start systems. The company sees the smaller batteries as a safer, more viable way to bounce back from its recent bankruptcy than by providing battery packs to power EVs. A123 still provides EV batteries to China, and hopes to provide them to Fisker, which is now owned by a mutual parent company, Wanxiang. A123's Detroit facility is currently building starter batteries for Mercedes-Benz, with microhybrid battery production expected in within the next few years. Read more at Automotive News. Tesla Motors Vice President of Worldwide Sales and Service Jerome Guillen is being reassigned to a role in customer satisfaction. After struggling sales in California and China, Tesla is also seeking sales executives for its three major sales regions: North America, Europe and Asia. "Once they are on board, Jerome's focus will be on post- sales activity from delivery to long-term customer care, where he has done an incredible job," says Tesla. For 2014, North America made up about 55 percent of Tesla's sales, while Europe and Asia made up 30 and 15 percent, respectively. Tesla expects those numbers to eventually be distributed evenly, and aims to increase sales by 74 percent this year. Read more at Automotive News. David Noland of Green Car Reports wants Tesla to address a double-pedal problem in the Model S. Noland says that when both the accelerator and brake pedal are pressed at the same time, it can increase the stopping distance, creating unsafe situations. Noland, along with other drivers with large feet, are having problems with this due to the narrow spacing between the pedals. Elon Musk has stated that the Model S limits torque in a double-pedal situation, but Noland's own tests find some inconsistencies. Noland would like to see a change to the firmware to address this problem. Read more at Green Car Reports.

NHTSA denies Tesla asked for Model S fire probe

The Tesla Model S is being investigated by the National Highway Traffic Safety Administration after three of the models caught fire; two of the electric cars impacted debris on the road, and one was involved in a single-car accident. This much we know for sure. Just exactly how the investigation came to be, though, is up for debate.
According to Tesla CEO Elon Musk, the California-based automaker requested that the government safety agency open the investigation, saying in a blog post, "We have requested that the National Highway Traffic Safety Administration conduct a full investigation as soon as possible into the fire incidents. While we think it is highly unlikely, if something is discovered that would result in a material improvement in occupant fire safety, we will immediately apply that change to new cars and offer it as a free retrofit to all existing cars."
Not so fast, counters NHTSA head David Strickland. Speaking to The Detroit News, Strickland had this to say: "Investigations are independent... We have never ... actually had an automaker ask for a formal investigation, but it causes a couple of implications: If a manufacturer asks me or asks the agency for a formal investigation, you've already made a determination that you may have a defect that imposes an unreasonable risk to safety. ... I don't think that would ever happen."
