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.

Volvo studying test of electric roads in Sweden

Volvo already announced the results of a study of wireless charging using a stationary C30, and now it's embarking on a more ambitious study of wireless charging involving moving city buses. Next year, in conjunction with the Swedish Transport Association, Volvo will build a section of electric road up to 500 meters long that would use inductive charging to refill the batteries while the bus drives over it.
Right now, the company's Hyper Bus diesel hybrid has to stop to plug in and charge at the end of its route. The company is looking for a way to keep buses in service while being able to run on electric power for greater lengths of time. The new line used for the study will be called ElectriCity, and will come online in central Gothenburg sometime in 2015. There's a press release below with more information.

Top 10 small cars with the longest total driving range

Editor's Note: Since this article was originally posted in the spring of 2015, much has changed in the automotive landscape, especially among those shopping for small car economy. With thanks to Volkswagen for their blatant cheating – and subsequent cover-up – on diesel emissions, the largest player in the diesel passenger car segment isn't playing – they're paying; billions are going for both car buybacks and federally-imposed penalties. And for a few VW execs there exists the very real possibility of jail. With the absence of a big player and the abrupt entrance – via Chevy's new Bolt – of an affordable EV with 200+ miles of range, we've limited the diesel listings to Jaguar's new XE. And for those wanting an updated look at efficiency and range, Autoblog has it – or the EPA has it. Long before electric vehicles were part of the mainstream conversation, car lovers and skinflints alike would boast about the total range of their vehicles. There's something about getting farther down the road on one tank of gas that inflames the competitive spirit, almost as much as horsepower output or top speed. Of course, the vehicles with the very best range on today's market are almost all big trucks and SUVs; virtually all have the ability to carry massive reserves of fuel. Top up a standard Chevy Suburban and you can expect to travel almost 700 miles (you'll need to stop before the Suburban stops...), while a diesel-fed Jeep Grand Cherokee manages almost as many. But what about vehicles that are smaller? The EPA has, essentially, three classifications for 'small' vehicles: Minicompact, Subcompact and Compact. All three are measured based on interior volume, meaning that some cars with rather large exterior dimensions and engines slot in next to traditional small cars. But even though impressive GT coupes from Porsche, Bentley and Mercedes-Benz may have much larger gas tanks to feed their powerful engines, that capacity is offset by higher rates of consumption... in most cases. We used the EPA's Fuel Economy Guide for model year 2017 cars as a start, calculating the official highway miles per gallon rating with each vehicle's tank capacity. The resulting numbers aren't necessarily real world, but they do offer a spectrum for total theoretical range. The eventual top ten surprised me on a few occasions, and comprised quite a varied list of vehicles. 10.
