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.

Carlos Ghosn's new lawyer, 'the Razor,' starts slashing

TOKYO — Carlos Ghosn's new lawyer took aim at Nissan, prosecutors and courts on Wednesday, dismissing the charges against the ousted chairman as an internal company matter and saying Japan was out of step with international norms by keeping his client in jail. "This should have been dealt with as an internal matter," Junichiro Hironaka, nicknamed the Razor, said at his first press briefing. Ghosn, who was arrested in November over alleged financial misconduct and remains in detention in a Tokyo jail, picked a new team last week with long-time defense attorney Hironaka as a key member to replace Motonari Otsuru, a lawyer who once ran the prosecutor's office investigating him. Hironaka's combative style contrasts with the low-key approach adopted by media-shy Otsuru. Ghosn's switch to an aggressive legal strategy came after his attempts to win bail failed and just before lawyers were due to sit down with prosecutors and judges for the first time to hash out a schedule for pre-trial discovery meetings, where prosecutors will reveal evidence and submit a list of witnesses. Hironaka said he didn't know why Ghosn picked him, but added that Ghosn probably wanted an experienced criminal lawyer as the case moved toward trial. The 73-year-old defense attorney is reputed for winning high profile cases, including the acquittal of a senior lawmaker, Ichiro Ozawa, on financial misconduct charges. He also helped free a senior bureaucrat Atsuko Muraki who was jailed for four months on corruption charges fabricated by prosecutors. Yet, even with greater legal firepower the former Nissan Motor Co boss faces a criminal justice system where only three out of every 100 defendants pleading not guilty are acquitted. Neither does Japan have a plea-deal mechanism that would allow Ghosn to agree to lesser charges for a lighter sentence. "The change in lawyers means a change in style, but the legal strategy will still be the same. I don't think it increases Ghosn's chance of an acquittal," said Masashi Akita, a defense lawyer at Shin-Yu Law Office in Osaka, ahead of Wednesday's comments by Hironaka. Ghosn has lost his perch atop an automotive alliance trio of French carmaker Renault SA and Japanese automakers Nissan and Mitsubishi Motors Corp. Attempts to win bail, including an offer to wear a GPS ankle bracelet and hire security guards to stop him trying to tamper with evidence, failed.

Is Nissan's Le Mans LMP1 racer really going to be front engined?

Since debuting the Nissan GT-R LM Nismo under a sheet earlier this year, Nissan has kept a very tight wrap on details about the racer. The company simply promised that the model would be on the starting grid for the 2015 24 Hours of Le Mans. However, the automaker had an aggressive attitude about the new program and said that the vehicle would "win in a very different way." The brand also hinted the final result wouldn't look like its competitors. This rendering suggests just how divergent the GT-R LM might be. Posted by Jalopnik, the rendering was supposedly based on the descriptions of people who have actually seen the racer. They described a car with a very long nose, and a rear that was potentially narrower than the front. From those details the pictures of a reverse Deltawing is almost conceivable. Judging by the original teaser image, this description actually sounds somewhat plausible too. The draping of the sheet in that photo could suggest some empty space at the back. According to this rumor, underneath that long snout could be an even bigger revelation – the engine. These days putting the powerplant ahead of the driver in a top-class endurance racer – even if it's behind the front axle for a mid-engine layout – is almost unheard of. Nissan trying it would certainly fall under a different way of winning. Though, such a thing was done by Panoz in the 2000s. Nissan is clear about keeping the racecar and road version at least somewhat related, especially technologically. Jalopnik speculates that the engine could be a gasoline-fueled twin-turbocharged V6 powering the rear wheels and a hybrid spinning the front and rear with a total system output of 1,000 horsepower or more. That figure is right on the money for modern LMP1 cars since the 2014-championship winning Toyota TS040 packs about 986 hp total. In the past few years, Nissan has failed to finish Le Mans with both the Deltawing that it sponsored and the ZEOD RC project. If these rumors prove true, then even getting the GT-R LM to see the checkered flag could be quite an accomplishment no matter where it finishes. Rumor has it that Nissan might show at least a glimpse of the vehicle during the company's Super Bowl ad this year.
