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 expands, shrinks Leaf recall for missing weld points

Chalk this one up to the quirks of the English language. The other day, we had a post on the recall of a small number of 2014 Nissan Leaf EVs that were missing weld spots. The official bulletin from the National Highway Traffic Safety Administration said that "any vehicle missing welds will be replaced, free of charge." We read that as saying that the welds would be replaced, but in fact it's the cars themselves that will be swapped out. NHTSA said that 211 Leafs were potentially involved in this recall, but we heard from Brian Brockman, Nissan's senior manager of corporate communications, that Nissan is actually looking at, "approximately 276" vehicles. More importantly, Brockman clarified that, "If a vehicle is found to be missing the welds, the entire vehicle will be replaced." NHTSA documents on Inside EVs show that Nissan expects just 0.65 percent of those Leafs will need to be replaced. Brockman wouldn't say exactly how many cars Nissan thinks are affected, but 0.65 percent of 276 is just 1.8 vehicles. Brockman did say that, "you'd be correct to say that we expect the number to be very low." Read Nissan's full statement below. Nissan is conducting a Voluntary Recall Campaign on approximately 276 MY2014 LEAF vehicles to inspect the front member assembly welds. Due to an isolated supplier process error that has been corrected, a small number of vehicles within a subset of MY2014 LEAF vehicles manufactured during a two-week period may have front frame member assembly components that were not welded to proper specification. This can affect crash performance. Within the next few weeks, affected LEAF owners will be asked to bring their vehicle to a certified Nissan LEAF dealer for an inspection. If the vehicle is determined to be affected, Nissan will provide owners with a brand new replacement vehicle at no additional cost. A loaner vehicle will be provided during the vehicle exchange process. It is anticipated that only a handful of retailed vehicles are affected by the weld issue and require vehicle replacement. Nissan is committed to a high level of customer service and satisfaction and is working with its dealers to provide an outstanding ownership experience to Nissan LEAF owners.

2015 Nissan Versa Sedan continues to prioritize space and price over looks

Nissan's refresh of its cavernous Versa Sedan is on hand today at the 2014 New York Auto Show. While we continue to appreciate the Versa for its space and low price, this slight restyling of the four-door sedan hasn't done much for its uninspiring appearance.
Newly enlarged headlights and a reworked, more Altima-like grille are the biggest changes to the front of this Versa, although Nissan has also added some brightwork around the revised foglight housings. Integrated turn signals liven up the mirrors, while the rear of the car wears a new and almost strangely sporty bumper.
Perhaps more importantly for prospective owners, Nissan has also made a few interior tweaks, with a new steering wheel and a revised center stack leading the change. There's some new available tech on the top-end SL model, as well.
