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 370Z Nismo Roadster Concept looks ready to roll

Honestly, we're kind of surprised this hasn't happened already. The Nissan 370Z Nismo is a pretty cool little package, better than ever in its 2015 model year iteration. So why not apply that same, go-faster, look-cooler formula to the topless Z Roadster? That's exactly what Nissan's done here in Chicago, showing the 370Z Nismo Roadster you see here. Aesthetically, it's pretty much the same as the coupe – except, of course, for the folding cloth roof that neatly stows behind the front seats. It's mechanically the same, too, with Nissan's 3.7-liter naturally aspirated V6 underhood, making 350 horsepower. Oddly, the concept car uses the company's seven-speed automatic transmission, but as Nissan explains, the majority of Z Roadster buyers spec their cars with the slushbox. "While it is only a design study at this point, we think the 370Z Nismo Roaster Concept would be a tremendous addition to the long and distinguished history of Z sports cars," Pierre Loing, Nissan's vice president of product planning in North America, said in a press release. It sure looks production-ready to us. Nissan 370Z NISMO Roadster Concept makes world debut at 2015 Chicago Auto Show - Combines legendary NISMO performance, style and technology with Nissan 370Z Roadster open-air motoring excitement - One-off design study created to gauge market interest in an ultimate factory Z® Roadster - Offers unique engine, suspension, exterior and interior features versus standard Nissan 370Z Roadster models – including 350-horsepower 3.7-liter V6 and NISMO-tuned suspension - Would join current Nissan 370Z NISMO coupe model, expanding NISMO lineup to five models As the heart and soul of Nissan performance for both the track and on the street, NISMO continues to set the standard for straight-from-the-factory enthusiast vehicles. The lineup of NISMO production models for 2015 includes the GT-R NISMO, 370Z NISMO, JUKE NISMO and JUKE NISMO RS. Yet as the popularity of NISMO models continues to grow – the 2015 GT-R NISMO is sold out, the 370Z NISMO accounts for 20 percent of total sales and JUKE NISMO models for about 15 percent – one group of performance enthusiast remains left out: Open-air sports car lovers. Enter the Nissan 370Z NISMO Roadster Concept, which makes its world debut at the 2015 Chicago Auto Show. The custom vehicle combines the long list of 370Z NISMO Coupe performance equipment with a modified 370Z Roadster body and interior.
