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.

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."

Recharge Wrap-up: Child Tesla driver hits baby in Chinese mall, Ram adds new CNG offering

A five-year-old child in a China shopping mall started a Tesla Model S at a display and hit a baby in a stroller. The baby fell out of the stroller and was unhurt, according to the report. A reporter from a local newspaper arrived at the scene to find the other Model S on display still powered on, this one with another child in the driver's seat. The cars had wooden blocks under the brake pedals and stickers warning the public not to touch the touchscreen. Police have opened an investigation into the incident.

The new offering, which is smaller and less expensive than the current CNG pickup (pictured), will be available as a regular cab two-door with two-wheel drive and a long bed. Ram has sold 1,000 of the current 2500 CNG four-door 4x4 offering since going on sale in 2012. Ram believes the new offering will expand sales to fleet operators looking for a less-expensive truck.

By now we're all familiar with regenerative braking, but thermoelectric harvesting from the motor, range extender or possibly even the exhaust could come to cars soon. Energy harvesting shock absorbers and exhaust turbines are also viable. Wind turbines could generate electricity while the car is parked, and piezoelectric energy harvesting could run minor electrical systems while the car is in motion. Enough energy harvesting could allow cars to use much smaller engines, and could extend the range of electric vehicles. Read more at Energy Harvesting Journal.
