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.

New V6 engines are only the start at Cadillac

Cadillac debuted its new family of V6 engines Friday, but that's not all General Motors' luxury brand has in store for the coming years. The six-cylinder powerplants will certainly help Cadillac in the near term, but they're just two of the many parts of the company's future strategy. GM has invested $12 billion in Cadillac to help the brand grow over the next five years, and the company will launch eight new products between now and 2020. That all starts with the launch of the CT6 flagship later this year – a fullsize luxury sedan we'll see for the first time in New York on March 31. The CT6 will introduce several new features and technologies to the Cadillac range, and with its launch also begins the slow restructuring of Cadillac's model-naming system. The new nomenclature means CT and XT badges for cars and utilities, respectively. Cadillac says that of the eight new vehicles it plans to launch by 2020, five of them will be first-time offerings in market segments where the brand currently does not play. But it's not just about new products – new powertrains are an important part of the Cadillac story, too. After the new V6 engines – a naturally aspirated 3.6-liter and a twin-turbocharged 3.0-liter engine – launch later this year in the 2016 ATS, CTS and CT6, the company says it has a strategy for V8 power – possibly a twin-turbo application – as well as future electrification. Cadillac also says it's working on adding four- and six-cylinder diesel powertrains, though it's unclear which vehicles will make use of those engines. This new six-cylinder engine family is indeed important, with Cadillac's chief engineer, David Leone, calling it the "most advanced V6 in the industry." With 335 horsepower, the 3.6-liter engine is the highest output, naturally aspirated V6 powerplant Cadillac has done – and that's SAE-certified, and on regular fuel. Beyond that, the 3.0-liter mill (pictured at right) marks the first application of GM's active fuel management system on a twin-turbocharged engine. This means that when full power isn't necessary, the TTV6 can run as a 2.0-liter V4 in order to save fuel. New transmissions are also part of the V6 engine story. GM's all-new eight-speed Hydra-Matic 8L45 gearbox will be paired to the 3.6-liter V6, and the 3.0-liter TTV6 will use the company's existing 8L90 transmission that is already found in the Chevrolet Silverado and GMC Sierra pickups (with the 6.2-liter engine).

Expect the Cadillac XT3 small crossover in late 2018

Cadillac's sedan-heavy lineup can't complete in this crossover-crazy market, it seems. The Detroit News spoke to Cadillac boss Johan de Nysschen and found out some more details about the brand's plan to alter its lineup to cater more to current consumer tastes. It's no surprise that these plans would include a small crossover, because de Nysschen has been talking about a vehicle smaller than the XT5 like this since at least 2015. The report also pins the Fairfax Assembly Plant, where GM builds the Buick LaCrosse and the Chevrolet Malibu, as the site for what could be called the XT3's production. That's not an immediately obvious choice, since the LaCrosse and Malibu are based on the latest evolution of the Epsilon platform, known as E2XX. And the XT5 is based on a crossover version of that same platform (known as C2XX), while XT3 is expected to be smaller than the XT5. So perhaps there's a different assembly line going into Fairfax, or the C2XX platform can be significantly shortened. We assume that the XT3 would be built on a smaller platform, perhaps the Gamma II that underpins the Chevrolet Trax and Buick Encore – which are built in either South Korea or Mexico, depending on which market they are to be exported to. The Encore is selling very well for Buick, with sales figures increasing through late last year. Another possibility is the D2XX platform that underpins the Chinese-built Buick Envision and the GMC Terrain and Chevrolet Equinox, perhaps with assembly happening at the CAMI plant in Ontario. At this early stage, without confirmation of GM as to what platform the XT3 will use or where it will really be built, it's too early to say what the Fairfax rumor means. This isn't the first time we've heard about a small Cadillac crossover. Back in 2015, de Nysschen told us to expect it sometime in 2018. But later that year, speaking to Reuters, he posited that it'd be closer to 2019. The Detroit News says de Nysschen told them it'll launch in the second half of 2018, splitting the difference between what we'd heard previously. Remember, Cadillac's only two vehicles in the segment are the XT5 and Escalade. We know that the brand is almost certainly scrambling to fill the holes in that side of the lineup. We think a three-row crossover will slot between the two, probably called the XT7.
