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.

Tesla spies something that begins with the letter D

Lest there be any doubt to the contrary, Tesla is a company on the move. Following the sensational Tesla Roadster, the Model S is now humming down roads across the country and around the world. And there's more to come: the entry-level Model 3, the upcoming Model X crossover... and something else. Two somethings, to be precise, going by this latest, cryptic tweet from Tesla chief Elon Musk.
The image enclosed appears to show the front of a Model S peering out from under a partially open garage door emblazoned with the letter D. Just what that letter stands for, we don't know. Usually we'd guess it stood for "diesel," but given that Teslas are powered purely by electricity, that'd probably be viewed as a backwards step. Drive? Possibly, if Tesla has an all-wheel-drive sedan in the works (which is does).
Whatever it is, we'll have to wait until October 9 before Tesla reveals the full thing. At that point it will also reveal "something else," though it's given even less indication as to what that might be. The Model 3? Production-ready Model X? A new Roadster? We'll find out in a week's time.

Recharge Wrap-up: Renault Zoe driving video, BYD Buses in Campinas

A new video shows drivers how to get the most range out of the Renault Zoe. By managing one's driving style, as we all know, one can minimize energy consumption. The Zoe's Econometer and R-Link screen give feedback about the rate of consumption, which helps let the driver know that they should hold back in the throttle. The R-Link system shows the distribution of energy in real time. It also analyzes the driving route and gives feedback at the end of the session. The Zoe also has an Eco button that automatically limits consumption regardless of driving style. Pre-programming climate control can also help improve range. These are all features we're more or less familiar with, but see how they work in the Renault Zoe in the video above. Tesla has announced it will release its second quarter results on August 5. After the automaker releases its financial information on that day, it will hold a live question and answer conference call webcast to discuss those results and outlook at 5:30 Eastern. The second quarter ended June 30. Read more at MarketWatch. Campinas, Brazil will add 10 BYD electric buses to its fleet. It is the first city in Brazil to have a zero-emissions bus fleet. Campinas will be using BYD's 39-foot, four-door K9 battery electric bus, but the K11 articulated electric bus will also begin testing in the city soon. Campinas Mayor Jonas Donizete likes the electric buses because "they are very comfortable, almost noise-free, and great for the environment," and they will help reduce the city's air and noise pollution. BYD plans to open factories for electric buses and solar panels in Campinas over the next year, investing about $108.5 million from 2014 to 2017. Read more in the press release below. BYD to Deliver 10 Electric Buses to Campinas Public Transport Fleet 07/22/2015 (Campinas, Brazil): BYD do Brasil and Campinas City Administration announced this month, the addition of 10 battery-electric buses to the city's public transportation bus fleet. Campinas is a city in the interior of the state of Sao Paulo, Brazil, and will be the first in the country to have a fleet of fully electric, zero emission buses operating in its streets. The model chosen to integrate the fleet in Campinas is the BYD K9, a 12-meter, 4-door, low-floor urban bus, with universal accessibility for passengers with limited mobility.
