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:

Super Cruise will make 2018 Cadillac CT6 semi-autonomous

General Motors has been working on its semi-autonomous driving system for years. Called Super Cruise, it had initially been slated for a fall 2016 debut. Of course, something as critical to safety as a self-driving system should ideally have the bugs worked out before putting it in the hands of customers, and the launch date had to be pushed back. It appears that Super Cruise is road-ready now, as Cadillac has announced the system will be available in the 2018 CT6 sedan when it goes on sale this fall. Super Cruise offers hands-free driving on the highway, taking control of steering and speed under the supervision of the driver. An attention detection system – a camera and infrared lights that track head position – ensures that the driver is paying attention and is available to take over driving responsibilities. If needed, Super Cruise will initiate a series of nags, including a flashing light bar on the steering wheel, to regain the driver's attention. If the driver is unresponsive, the system can bring the car to a safe stop and use OnStar to call first responders. The system employs a suite of sensors, cameras, and GPS, as well as precision lidar-scanned map database, to place the car where it needs to be on the road and in the center of its lane. It only works if the sensors detect appropriate road conditions, and is limited to the more predictable terrain of divided highways with on- and off-ramps. Yes, it's limited, but safety is paramount, and drivers who spend a lot of time on the highway will appreciate the convenience nonetheless. Related Video:

Cadillac CT6 loses the entry-level 2.0-liter turbo four-cylinder

General Motors continues its engine rationalization among product lines. A few days after Chevrolet dropped the old-generation LTG 2.0-liter turbocharged four-cylinder from the Traverse, Cadillac has jettisoned the new-gen LSY 2.0-liter turbo four from the CT6 range. Given a look at the dealer ordering system, Cadillac Society said the 2.0-liter option shows "built out" or "no longer available," and the online configurator at the Cadillac site confirms the omission. The retired engine can be had in the XT4 crossover, rated at the same 237 horsepower and 258 pound-feet of torque. This means a couple of things for the big sedan. The CT6 entry price was $50,495 before destination, but fitted with the now-base 3.6-liter six-cylinder, the entry price has gone up to $55,495. The other change is that rear-wheel drive is no longer available; the three remaining engine choices come with all-wheel drive. Those engines are the NA 3.6-liter V6 with 335 hp and 284 lb-ft of torque, a 3.0-liter twin-turbo V6 with 404 hp and 400 lb-ft, and coming in a few months, the detuned 4.2-liter Blackwing twin-turbo V8 with 500 hp and 574 lb-ft, down from 550 hp and 627 lb-ft. Cadillac Society thinks one of the possibilities for making the move could be that GM is having a hard time meeting demand for the 2.0-liter. That might be, but we think no matter the reason, the result puts more logical pricing between the midsize CTS/CT5 and the full-size luxury flagship. We don't know how Cadillac will price the coming CT5, but there's now an $8,005 difference between the CTS and the CT6, instead of the $4,000 gap when the 2.0-liter was a CT6 option. Mercedes-Benz, for instance, puts a $12,000 gap between the C-Class and the E-Class, a $38,000 gulf between the E-Class and the S-Class. There's a $19,000 difference between an Audi A4 and A6, a $25,000 difference between an A6 and an A8. It isn't clear if this will affect every other market where the CT6 is sold. The Canadian, Mexican, and French Cadillac site configurators don't list the 2.0-liter turbo, but the Chinese Cadillac site does.
