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.

Nissan, Kia under investigation over occupant detection systems

Kia and Nissan are facing separate investigations by the National Highway Traffic Safety Administration because of alleged problems with the occupant detection systems in their vehicles' airbags. The larger investigation is NHTSA's new engineering analysis into 986,826 Nissan and Infiniti vehicles. They include the 2013 Nissan NV200 and 2013-2014 Altima, Leaf, Pathfinder, and Sentra. Among the Infinitis, there are the 2013 JX35 and 2014 Q50 and QX60. Owners allege the occupant classification system can misidentify passengers and turn off the airbag if they don't weigh enough. Nissan recalled over a million vehicles worldwide last year to fix the same problem with a software update, but NHTSA kept getting complaints about the issue after the repair. The agency opened a preliminary evaluation in March, and after 1,271 complaints it has now been updated to an engineering analysis. The Feds intend to evaluate the effectiveness of Nissan's solution. NHTSA is also opening a preliminary evaluation into the 2007-2009 Kia Spectra for the occupant classification not working properly, and it could affect an estimated 186,000 of these vehicles. The government agency has 43 complaints from people allegedly reporting the failures. According to NHTSA, the issue could result in the airbag not deploying with enough force or not activating at all in an accident. This investigation is meant to assess the scope of the potential flaw, and there's no recall yet. INVESTIGATION Subject : Occupant Classification System Fault Date Investigation Opened: SEP 01, 2015 Date Investigation Closed: Open NHTSA Action Number: PE15031 Component(s): AIR BAGS All Products Associated with this Investigation Vehicle Make Model Model Year(s) KIA SPECTRA 2007-2009 Details Manufacturer: Kia Motors America SUMMARY: The Office of Defects Investigation (ODI) has received 43 complaints alleging a malfunction of the front passenger seat occupant classification system (OCS) in 2007-2009 Kia Spectra vehicles. The complaints report illumination of the SRS (air bag) warning light. All of the complaints allege the cause of the light illumination to be a malfunction of the OCS sensor mat imbedded in the passenger seat cushion, and/or report the presence of diagnostic trouble code B1448 which relates to the OCS sensor mat also. Many of the complaints note the malfunction occurred after the warranty period expired and mention high repair costs as a major deterrent to repairing the vehicle.

Nissan ZEOD RC completes 24 laps at Le Mans

Well, that's a nice start. Nissan says a test version of its ZEOD RC racecar has completed its first 24 laps at Le Mans in France. And, aside from two "small technical issues," things went swimmingly. The ZEOD (which stands for "zero emissions on demand") RC pairs a 1.5-liter, three-cylinder engine with a couple of electric motors and includes regenerative braking. The Japanese automaker first started testing the vehicle last fall. The first ZEOD prototype was unveiled at Le Mans last summer. Driven by Wolfgang Reip and Tommy Erdos, the test-version ZEOD suffered from a broken fuel pump and faulty exhaust, but still completed "large sections" of the circuit on electric power alone, so Nissan is gonna call the test run a success. The goal, of course, is to complete a single, 8.5-mile lap at Le Mans purely on electric power. Nissan will test the real version of the ZEOD this week in the UK. Satoshi Motoyama and Lucas Ordonez will drive with Reip at the actual Le Mans race. Check out Nissan's press release below, and take a look (you can cringe a bit if you want) at a really cool crash-test video of the car from last month here. Nissan ZEOD RC on track at Le Mans for the first time SILVERSTONE, UK & LE MANS, FRANCE – The Nissan ZEOD RC completed its first 24 laps of Circuit de la Sarthe with GT Academy winner Wolfgang Reip and two-time Le Mans P2 winner Tommy Erdos at the wheel. While the car was delayed with two small technical issues – a broken fuel pump issue and a broken exhaust – today's test was an important step in the development of the car that aims to complete an entire lap of Le Mans on pure electric power. "Today has been a very important step in the development of the car and what we have achieved is actually quite remarkable," said NISMO's Global Head of Brand, Marketing & Sales, Darren Cox. "We knew we were tackling a huge challenge with the goal of building a car that could complete an entire 8.5 mile lap of Le Mans on nothing but electric power. We have certainly discovered why nobody has tackled it previously. "We completed large sections of the circuit today on EV power and learned a great deal," Cox continued. "Today was about testing the systems and ensuring the transition from electric to internal combustion power was seamless. Testing at other venues is extremely valuable but there is no substitute to running here at Le Mans.
