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 Sentra gets mean with 240-hp Nismo concept

Nissan's Sentra Nismo Concept made its world debut at the LA Auto Show today as part of the Japanese automaker's intitiative to expand its performance line of factory performance models, and it's packing a turbocharged inline four-cylinder engine with 240 horsepower and 240 pound-feet of torque - that's 110 hp more than the regular Sentra.
Of course, no high-performance version of any car would be complete without the suspension upgrades to handle the power, and Nissan has fitted Nismo-tuned suspension and a limited-slip differential to the little front-wheel-drive sedan. With such an increase in power, Nissan wisely chose to swap out the stock brakes for the Brembo calipers and discs from the 370Z. Larger 225-millimeter-wide tires are wrapped around 19-inch Rays wheels and contained within wider fender flares. The steering and six-speed manual transmission also were tuned by Nismo.
The exterior gets new aerodynamic bits, such as a revised front fascia, a chin spoiler and a new rear spoiler, while the interior gets a nice set of Recaro seats and a leather-and-Alcantara steering wheel. For more information on the Sentra Nismo Concept, check out the press release below, and feel free to head over to the auto show photo gallery to see the car up close.

Daimler consulting with Ford about 3-cylinder engines

Soon enough, Ford will offer its 1.0-liter EcoBoost three-cylinder engine under the hood of the Fiesta here in the United States, building on the success of the small powerplant overseas. In fact, this success has caused other automakers to take notice, and according to Automotive News Europe, Daimler is now talking to Ford about this engine for use in its own products.
In other markets, Ford offers the 1.0-liter mill under the hood of the Focus (we had the chance to sample this package on our home turf), as well as the B-Max MPV. For this new collaboration, Daimler would use the turbo-three in the next-generation Smart ForTwo, as well as the Renault Twingo, which the German automaker will be collaborating on as part of its alliance with Renault-Nissan. Speaking to AN, a Mercedes-Benz engineer called the 1.0-liter mill an "interesting and impressive engine."
In exchange for details about the EcoBoost inline-three, Daimler will supply Ford with information regarding its Euro6 stratified lean-burn gasoline engine, which is found in the new E-Class sedan.
