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.

Is a Nissan Leaf with a 250-mile range less than three years off?

Nissan CEO Carlos Ghosn has never shied away from bold proclamations. Most recently, he implied that an electric vehicle with a single-charge range comparable to that of a gas-powered vehicle on a full tank may be fewer than three years out. We'd love to see it. Indeed, Ghosn said that such a car may be around in the "near future," Hybrid Cars said, citing a presentation Nissan CEO Carlos Ghosn made to shareholders earlier this week. He also showed a video of a Nissan Leaf in Japan, which appears to start out on a trip with 417 km (259 miles) of range available. The 2015 Leaf's single-charge range is rated at 84 miles in the US. How to get another 120 miles or so? Ghosn's talking about a still-lighter vehicle as well as cheaper batteries and improved battery chemistry. He also alluded to shorter recharging times. Last month, word got out that Nissan was working on a top-of-the-line Leaf that, as soon as this fall, would include a 30-kilowatt-hour battery, up from the standard 24-kWh version. Such a variant, which would be launched ahead of the next-generation Leaf slated for as soon as 2017, could boost the Leaf's single-charge range to as far as 105 miles.

Nissan cooks up throwback livery for Le Mans

Nissan may not have won the overall 24 Hours of Le Mans before – Mazda remains the only Japanese automaker to have done so – but when it returns to Le Mans this year, it will be armed with other bragging rights. And it's that past accomplishment that Nissan is celebrating with this throwback livery. Twenty-five years ago, Mark Blundell set a blistering qualifying lap in the No. 24 Nissan R90CK, lapping La Sarthe in 3:27.020. That was enough to put the Datsun on pole for the race, and though it never made it to the finish line, it set a record that stands to this day when it hit 227 miles per hour on the Mulsanne straight – even with the chicanes in place. That car wore a blue livery with white and red that still holds a place of honor in the hearts of racing fans. So to mark its return to Le Mans a quarter century later, Nissan is decking out its new GT-R LM Nismo in a tribute livery that will be worn by the third entry the company will be fielding in the race. Nissan celebrates 1990 pole lap of Le Mans with retro livery for LM P1 car LE MANS, France – Nissan today revealed a very special livery that will feature on the No.21 Nissan GT-R LM NISMO at Le Mans. Exactly 25 years ago, at the peak of the Group C era, Mark Blundell put the Nissan R90CK on pole position with a stunning 3:27.020 lap of the Le Mans circuit. The No.21 Nissan GT-R LM NISMO is Nissan's third LM P1 car that will be raced by current Super GT Champion Tsugio Matsuda (JAP) and two winners of GT Academy, Lucas Ordonez (ESP) and Mark Shulzhitskiy (RUS). The No.24 Nissan R90CK will also appear at Le Mans in a special parade to mark the anniversary of the pole lap in the hands of the man who took it to the top of the tables 25 years ago, Mark Blundell. The 1100bhp car may not reach speeds of 366 km/h (227 mph) as it did in 1990, but it is certain to grab everyone's attention. "That lap of Le Mans is certainly a very fond memory for me," said Blundell. "It was one of those moments where time stood still and everything went perfectly. You remember those moments, as they don't happen all that often. It's great to see Nissan celebrating that time with the retro livery on the #21 Nissan GT-R LM NISMO. I can't wait to see it on track at Le Mans." "Our racing heritage is hugely important to us," said Darren Cox, Global Head of Brand, Marketing & Sales, NISMO.
