2019 Autoblog Technology of the Year finalists revealed

Every fall, we line up a range of new models with the latest and most compelling automotive technology from the past year. We test everything from semi-autonomous systems like Tesla's Autopilot to trick suspension setups like the Multimatic spool-valve shocks on the Chevy Colorado ZR2. We spend months paring down the list to a small group of contenders. After testing, dinner and healthy debate, we tally up the votes and name our winner. For Autoblog's 2019 Technology of the Year Award, our three finalists are the Cadillac CT6 with Super Cruise, the Infiniti QX50 with Variable Compression Turbo and the Mercedes-AMG E 53 with EQ Boost. Super Cruise is an advanced SAE Level 2 semi-autonomous system, though Cadillac (unlike some of its rivals) is reluctant to push that point. Cadillac would like you to think of this as an advanced driver assistance feature rather than a semi-autonomous system. Super Cruise allows completely hands-free highway driving. Thanks to a driver-facing camera, the system forces the driver to keep his or her eyes on the road even if hands are off the wheel. Although the CT6 is being discontinued, look for Super Cruise to make its way to other Cadillacs soon. VC Turbo is a little more complicated. Basically, Infiniti's 2.0-liter turbocharged inline-four can vary the compression ratio on the fly. In general, turbocharged engines are more efficient than naturally-aspirated engines when on boost, but can perform worse at low revs. VC Turbo allows for a best-of-both-worlds situation, increasing the compression at low revs and backing it off once the turbo spools up. The best part is that it does so seamlessly, with only a dash readout letting you know what's going on under the hood. Our third finalist is the EQ Boost 48-volt system in the Mercedes-AMG E 53. Like VC Turbo, EQ Boost does a lot just beneath the surface. Mercedes has developed a new turbocharged 3.0-liter inline-six and paired it with a small electric motor. While the car can't run on electricity alone, the motor helps improve both efficiency and performance, smoothing shifts and filling in low-end torque before the turbos spool up. Think torque fill, similar to a McLaren P1. Who can complain about better fuel economy and more torque? Look for the 48-volt system to make its way into most of the Mercedes-Benz lineup. The winner will be revealed next week on Autoblog, and we'll present the award Jan. 15 at the Detroit Auto Show. Related Video:

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.

Cadillac Escala Concept shows off a softer side of American luxury

When Cadillac announced that it would be appearing at Monterey Car Week with a stunning, new concept, the news sent a rush of blood to the head. Would it be a CT6 Coupe? A new V-series model? A follow-up to the show-stopping Elmiraj? Tonight, at the beginning of a weekend of festivities to tantalize automotive enthusiasts and aficionados, Cadillac instead showed off a glimpse of reality: the Escala four-door coupe concept. It wasn't behind a flat-white background, but at a futuristic yet modern home nestled in the hills that Cadillac president Johan De Nysschen introduced the Escala as a "point of inflection" for the brand. Keen observers will note that "Escala" is nearly "Escalade," but any similarity between the two vehicles ends there. De Nysschen noted that the four-door is meant to "relentlessly drive this brand back to its place at the pinnacle of premium." "Nothing less will do," de Nysschen said. The Escala is neither as bold as some recent Cadillacs to take the stage, nor as brash. From a distance, it has a wide, muscular stance wrapped in a tailored suit. Up close, it almost resembles a four-door Camaro — perhaps a nod to the work of former Holden design chief and incoming General Motors director of design, Michael Simcoe. De Nysschen described the Escala project as an "opportunity for designers to flex their creative muscle." The Escala seems to have a footprint mirroring that of a Mercedes-Benz CLS-Class, but it feels wider and smaller at the same time. Is the shape derivative? Perhaps, but the Escala's design is less a reflection of a future, incognito Cadillac, and more of a chance for the brand to show off the details that might soon become icons. The Escala's shape may not be earth-shatteringly different, but the truth is in its details. The mirrors are as thin as designer spectacles. The C-pillar offers an opportunity to show off Cadillac's latest take on the Hoffmeister kink. A glass roof adds visual airiness. And a simple "GM DESIGN" badge sits below the side doors, in deference to the stylists who labored to make the Escala different. The most defining element of the concept is the way it utilizes light. There isn't anything blinding about its lighting, but that means you can focus on the shape and appreciate the ambience. The depth of the LED tail lights adds visual length to the Escala and shows where Cadillac's designers placed the most importance. It's contrast and beauty at once.
