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.

Epic Electric American Road Trip goes 12,000 miles on EV power

Twenty-seven states. 12,000 miles. Zero gasoline. Those are the headline numbers for the "Epic Electric American Road Trip" that ended in Venica, CA today, just in time for Earth Day. Norman Hajjar, the managing director of Recargo's driver research division, PlugInsights, made the journey in a stock Tesla Model S both as a way to draw attention to electric vehicles (he's trying to get Guinness World Record to verify that this was the longest vehicle journey ever taken using 100 percent electric power) and to show that long-distance road trips are possible even with today's charging infrastructure. This was certainly a trip for an EV diehard, since it was made up of 109 hours of charging and 213 hours of driving. That leads to the second part of Hajjar's reason for driving criss-cross across the US: to "draw attention to needs for further improvement." You can relive the journey over at Plugshare or on Twitter. World Record-Breaking Electric Vehicle Journey Crosses Finish Line "Epic Electric American Road Trip" marks the longest ever journey made with zero fuel costs VENICE, Calif., April 21, 2014 /PRNewswire/ -- Today marks the completion of the record-setting Epic Electric American Road Trip, a 24-day, 12,183-mile battery-powered journey sponsored by electric vehicle (EV) software and information services company Recargo Inc. The trip is seeking Guinness World Record verification for longest vehicle journey ever taken using 100% electric power, and served to emphasize the possibilities of the nation's current electric vehicle charging infrastructure. Norman Hajjar, Managing Director of Recargo's driver research division, PlugInsights, crossed the finish line in a stock Tesla Model S sedan. At the trip's end, Norman has ventured across a 27-state route spanning the four corners of the lower 48 states: Washington, Maine, Florida, and California, ending at Recargo's offices in Venice, California. Hajjar took advantage of Tesla's newly built, proprietary string of cross-country "Supercharger" stations, in order to make the coast-to-coast electric venture. "We wanted to illustrate what's possible with the nation's charging infrastructure, and draw attention to needs for further improvement," said Norman Hajjar. "The plausibility of a mass switch to EV usage in America simply can't be separated from the need for a robust fast-charging network. I've traveled over 12,000 miles in under 3.5 weeks.

Rinspeed details Tesla-based autonomous XchangE concept for Geneva [w/video]

Like it or not, the age of the self-driving autonomous automobile is just around the corner. But what form will a car's cabin take when the emphasis is taken off of human operation? That's the question that Rinspeed aims to answer with the XchangE concept. Previewed two months ago, Rinspeed has now revealed details, photos and even video footage of the self-driving electric vehicle. This year's concept car from the self-styled "Swiss idea factory" takes a Tesla Model S and modifies it for autonomous operation, freeing up the driver to sit back and enjoy the ride.
The redesigned cockpit includes a pair of highly adjustable front seats that can tilt, swivel and recline to make for a business class-like cabin space for driver and passenger. The drive-by-wire steering wheel slides out of the way when not in use. The dashboard displays all manner of data on four screens through a scalable infotainment package controlled by gestures, based on HTML5 and developed by Harman. The vehicle is fully networked with car-to-car communications and integrated LTE connectivity furnished by Deutsche Telekom. Access to the calming cabin space is granted by RFID technology, there's an LED plexiglass roof panel and a Carl F. Bucherer timepiece mounted in a watch winder on the dashboard.
It all comes across as a rather innovative take on the automobile from a design firm known for doing exactly that with its annual Geneva show cars. There's plenty more to digest in the press release, so check it out along with the video footage below and scope out the hundred-plus high-resolution images in the gallery above.
