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.

2020 Cadillac CT4-V, CT5-V revealed, less powerful than predecessors

Expectations have reached stratospheric heights for the 2020 Cadillac CT4-V and 2020 Cadillac CT5-V, and for good reason: Their ATS-V and CTS-V predecessors were potent sports sedans with gobs of power and handling and braking to match. Now the new sedans have been revealed, and they're not what we expected. They each lose two cylinders compared with the other vehicles, and on paper, they don't look as capable. But we do have hope that these won't be the end-all, be-all performance Cadillacs. First, let's look at the cars. The CT4-V will be the base of the V brand, and it's our first look at the small luxury sedan. It has a roofline and window treatment more like past Cadillacs, eschewing the C-pillar garnish of the CT5. It also naturally gets dark trim and headlights, a unique spoiler and quad tailpipes to distinguish it as a V. Under the hood is a turbocharged 2.7-liter four-cylinder that is based on the engine in the new Chevy Silverado. It makes 320 horsepower and 369 pound-feet of torque, a far cry from the ATS-V's 464 horsepower and 445 pound-feet of torque. Cadillac CT4-V View 12 Photos Power goes through a 10-speed automatic transmission only. Both rear-wheel drive and all-wheel drive are available. It gets a mechanical limited-slip differential whereas the ATS-V had an electronically controlled limited-slip differential a la Camaro ZL1. The brakes have four-piston calipers at each corner versus six-piston front units and four-piston rear units on the ATS-V, and the rotors are smaller. Magnetic Ride Control remains standard on the rear-drive version, but the all-wheel-driver version sticks with conventional shocks. The new CT4-V is about 200 pounds lighter than the ATS-V, though, and it has 50/50 weight distribution. Additionally, both the CT4-V and the CT5-V have Super Cruise available as an option. Moving on to the CT5-V, it looks like a regular CT5 but with dark trim and lights, quad tailpipes and a unique rear diffuser. Instead of the CTS-V's 640-horsepower supercharged V8, the CT5-V uses a twin-turbo 3.0-liter V6 making 355 horsepower and 400 pound-feet of torque. Changes made to the 3.0 for the CT5-V include a new intake system and new exhaust, and it revs higher too. Like the CT4-V, it comes with a 10-speed automatic and either rear-wheel drive or all-wheel drive. It does get the electronically controlled limited-slip differential.

Here are all the cars GM is axing as part of its restructuring

GM plans to kill off a couple of great and a few meh cars as part of its restructuring. Here's a rundown of all the cars being phased out of production. None of the vehicles GM axed were SUVs or crossovers. Instead, it was an action reminiscent of what Ford recently decided to do by discontinuing U.S. sales every Blue Oval sedan. GM just didn't explicitly say, "We're killing our cars," like Ford did — probably a smart move by GM. Keep scrolling down to see the full list of deceased GM models. Chevrolet Volt This one was the most surprising of all the cars GM decided to can, primarily because cars with plugs are supposed to be our future. However, maybe consumer demand just isn't quite there yet for a plug-in like the Volt. We came up with all sorts of ideas for what was to blame for the untimely demise of the Volt, so go check that out for a full breakdown of the situation. Cadillac CT6 Here's another car we'll be sad to see go. Cadillac's flagship sedan was such a joy to drive, and it served as the conduit to deliver GM's semi-autonomous Super Cruise system, which still hasn't been surpassed by any other company's technology in our books, even Tesla's Autopilot. That being said, GM does plan to produce the CT6 until March, with the last cars coming off the line set to be twin-turbo V8 V-Series models. If it's going to go, this seems like a pretty great way to make an exit. We'll be patiently awaiting the next flagship Cadillac once this one finally fades away. Chevrolet Impala The Impala is actually a pretty good car. It doesn't sell terribly, and we think it's a completely satisfactory car to drive. However, people would rather have a Traverse or Equinox these days, making the Impala one of the vehicles to find itself on this list. Chevrolet is keeping its smaller brother, the Malibu, but a big, full-size sedan just isn't what people are ordering up these days. It's unfortunate to see it go, but we won't be broken up over it. Chevrolet Cruze We wouldn't rank the Cruze at the top of the compact car class, but if you were looking for a small, cheap American car, it was either this or the Focus. The Cruze had the potential to be a true small performance car if Chevy had ever wanted to make it into one. But sadly, we're seeing it bow out before Chevy ever tried to slot a hot engine and suspension in there to make it competitive with other hot hatches. A Cruze SS would have made enthusiasts take notice.
