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 recalls 120k examples of ATS for fire risk

Cadillac is recalling a total of 119,339 units (96,145 in the US alone) of the 2013-2016 ATS sedan, because the coil antenna module that powers the rear defogger can overheat. The problem has been linked to four fires, but there have been no injuries, fatalities, or crashes, according to the automaker. During manufacturing, the antenna might have been produced with "critically weak terminal connectivity." If being cycled on and off often or used continuously, these faulty examples can overheat, leading to a fire in the driver's side rear pillar. According to the company, "less than 1 percent of the recalled vehicles are expected to have the condition." According to the National Highway Traffic Safety Administration (in a PDF), the fix is a reflash for the ATS' Electronic Climate Control module that automatically turns on the rear defogger when the engine starts. In addition, 2013 models keep the system on continuously at low temperatures at highway speeds and this is also being disabled in the update. The changes are meant to cycle the coil less often, but owners can still turn it on manually.

If the module has the condition and is subjected to excessive cycling or continuous operation, it may overheat and a fire may develop inside the rear pillar on the driver's side of the vehicle. Less than 1 percent of the recalled vehicles are expected to have the condition. GM is aware of four fires but no injuries, fatalities or crashes. Including Canada, Mexico and exports, the total population of the recall is approximately 119,339. RECALL Subject : Rear Defogger Coil Antenna Module may Overheat Report Receipt Date: SEP 03, 2015 NHTSA Campaign Number: 15V558000 Component(s): VISIBILITY Potential Number of Units Affected: 96,145 All Products Associated with this Recall Vehicle Make Model Model Year(s) CADILLAC ATS 2013-2016 Details Manufacturer: General Motors LLC SUMMARY: General Motors LLC (GM) is recalling certain model year 2013-2016 Cadillac ATS sedan vehicles manufactured April 23, 2012, to September 2, 2015. In the affected vehicles, the coil antenna module that powers the rear defogger system may generate excessive heat due to excessive cycling or continuous operation.

Super Cruise’s failsafes

Even though Super Cruise is not a fully autonomous system, it incorporates redundancies like those used in aircraft to ensure failsafe operation. Before taking off on a 700-mile, 11-hour test drive of the system — and putting my life in its hands without my hands on the wheel — I sat down with Daryl Wilson, lead development engineer for Super Cruise, to get a deep dive into the system and its critical safety backups. Autoblog: First, what makes Super Cruise different from similar systems? Wilson: The key differentiator for Super Cruise is hand-free driving. It's an industry first in that respect. Our competitors require the driver at minimum to place their hands on the wheel with some frequency to ensure that the car knows that the driver is there. We don't. Two key technologies allow us to do this. One is our Driver Attention System, which is our methodology for making sure the driver is engaged with the vehicle and engaged with the road. This is a driver assist system, not a fully autonomous system. So it requires driver engagement. We use an infrared camera that constantly monitors the driver's face to determine the direction they're looking. We're looking for the driver to be what we call on-road — not on the center stack, not to left or right or down. That's all done by the tracking of the face. We also track that the eyes are open. It's infrared because at night you need to illuminate the face and you can't be shining a light into the driver's face. Then we have our lidar mapping that provides a foundation for control and redundancy to ensure safe performance. Autoblog: How does the mapping act as a redundant feature? Wilson: This system is only for use on divided, controlled access highways. What I mean by a divided highway is something more than a painted line between you and oncoming traffic. Whether that's a grassy area in between the lanes or a concrete barrier, anything that separates you from oncoming traffic. That's the divided highway part. The controlled access part is entrance ramps and exit ramps. Not with roads that cross at grade, with traffic crossing at the same level. To do that we geofenced these roads to ensure that operation is only allowed in these conditions. We don't just recommend you use it there; we ensure that you only use it there.
