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.

Infiniti installs Taisuke Nakamura as new design chief

The cubicles and corner offices at Infiniti HQ in Japan continue to change hands. Infiniti Global Design Chief Karim Habib, only in that position for about two years since leaving BMW in 2017, has left the Japanese luxury brand "to pursue other opportunities." In his place, Nissan has elevated Taisuke Nakamura, a 26-year company veteran who is currently Nissan's program design director responsible for global design strategy, and concept car and production vehicle design. Nakamura has a stout design resume in service to both Nissan and Infiniti, having worked on the Qs Inspiration sedan concept (above) shown at the Shanghai Motor Show in April, the QX Inspiration crossover concept shown at the Detroit Auto Show this year (below), and the Prototype 10 speedster concept revealed at Pebble Beach last year (bottom). All of those were electric concepts, making Nakamura the point man for Infiniti's push into electric vehicles and hybrids, and the carmaker's introduction of a new design language. Last year, Infiniti said it would have a new EV on the market in 2021, as well as "e-Power" series hybrids with small battery packs charged by gas-powered generators.   Those EVs should fully embody the brand's new design DNA, seen initially in the recent concepts. The automaker said around the Qs reveal that the new "aesthetics are underpinned by Infiniti's desire to challenge convention and design cars which are engaging, enriching, enabling and enchanting – what the company calls its ‘4ENÂ’ approach to design." At the QX reveal in January, Habib said that as engineers made a "shift towards smarter, more compact and less intrusive powertrains, we were able to create an alternative form with flowing gestures, more engaging in character and more enriching in experience. With its long cabin, balanced proportions and muscular stance, the concept heralds in a new era for Infiniti models.” Infiniti said Nakamura takes up his post next week, Sept. 1, and will report to the same boss he has now, Alfonso Albaisa, Nissan's global design head. Aside from Habib, other top non-Japanese Nissan executives such as Daniele Schillaci, Jose Munoz and Trevor Mann have left the Japanese automaker in the recent past, since the arrest of Carlos Ghosn. The former chairman, who faces charges of fraud and misconduct, is awaiting trial in Japan over charges including enriching himself at a cost of $5 million to Nissan, Japan's No. 2 automaker.

Carlos Ghosn re-arrested and thrown back in jail [UPDATE]

TOKYO — Tokyo prosecutors arrested Nissan's former chairman Carlos Ghosn on Thursday for a fourth time, on fresh allegations that cut short his brief time outside detention. Early in the morning, Ghosn was taken from his apartment in Tokyo to the prosecutors' office and then sent to the Tokyo Detention Center, the same facility where he spent more than three months following his arrest in November. He had been released on bail just a month earlier. It's unclear how long Ghosn may be detained under the latest arrest, which involves what prosecutors said was a new alleged crime. "My arrest this morning is outrageous and arbitrary," Ghosn said in a statement issued Thursday. "It is part of another attempt by some individuals at Nissan to silence me by misleading the prosecutors. Why arrest me except to try to break me? I will not be broken. I am innocent of the groundless charges and accusations against me." The prosecutors defended the move, saying the latest allegations are a new case requiring precautions to prevent Ghosn from destroying evidence. They allege $5 million in funds sent by a Nissan subsidiary to an overseas dealership were diverted to a company controlled by Ghosn. "We now have a totally different case, and we are only doing what we think is right," Shin Kukimoto, deputy chief prosecutor at the Tokyo District Prosecutor's Office, told reporters. "As a result of our investigation, we have a new case in which he must be detained, and we have appropriately obtained an arrest warrant from the court," he said. Ghosn, 65, was first arrested on Nov. 19 on charges of under-reporting his compensation. He was rearrested twice in December, including on breach of trust charges. The multiple arrests prolong detentions without trial and are an oft-criticized prosecution tactic in Japan's criminal justice system. The allegations in the most recent arrest cover three money transfers from 2015 through last year, according to the prosecutors. Kukimoto said the new allegation of breach of trust is different from an earlier charge made in January. The companies where the money was transferred to, the motives, and the alleged scheme are all different, he said. He refused to identify the three companies allegedly involved but said one company was in effect owned by Ghosn. Unlike an earlier case, in which Ghosn caused damage to Nissan to benefit himself and a business partner, this time it was merely "for his own personal benefit," Kukimoto said.
