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's Nismo celebrates 30th year with video retrospective

Nismo, the motorsports and high-performance arm of Nissan, has a lot of racing success to celebrate in its history and possibly even bigger accomplishments to look forward to. The company is commemorating its 30th anniversary with a video looking back at its most important milestones from each year of its past.
Nismo's job first and foremost at its genesis was to excel at motorsports. It wasn't too long after the division was founded in 1984 that the company made its first of many attempts to take an overall victory in the 24 Hours of Le Mans. It never quite succeeded in that goal, but still managed to do well in long-distance competition elsewhere. At the same time, Nismo was racking up wins in touring car races in Japan.
Eventually, the division's engineers started dipping their toes into tuning road cars, in addition to going racing. What began as something sporadic has become a growing part of the Nissan lineup with Nismo-branded models of the 370Z, Juke, Note in Europe and the GT-R.

Nissan's London Black Cab postponed because it can't meet emissions targets

Emissions concerns in London are causing headaches for Nissan, as the company continues its efforts to bring its Black Cab to the city's streets. A proposed ultra-low emissions zone could lead to standards in the city center that are so strict the gas-powered taxi can't meet them, AutoExpress reports. It's unclear just how low the new emissions standards may be, although AE references London's mayor, Boris Johnson, and his drive to make every London taxi emissions-free by 2018 as a particular thorn for the Japanese automaker. It's worth noting that the NV200 taxi is both cleaner and more fuel efficient than London's current fleet of iconic black cabs. That alone makes it seem like reason enough to get the new cabs on the streets. But it's the strictness of the proposed standards and the apparently set-in-stone nature of the NV200's current engineering that is holding up the cab's future. While Nissan offers an emissions-free e-NV200, it would reportedly need to completely reengineer the NV200-based cab to meet the future standards if they're approved. Whether that will happen, though, remains an open question.
