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:

Mercedes-Maybach GLS prototype caught testing with its big new grille

The new Mercedes-Benz GLS is a massive tech fortress on wheels, so the Maybach GLS is bound to be a massive tech castle. Last we heard from the gigantic Benz SUV was that it was going to be built at Mercedes’ Alabama plant. With a starting price expected to be around $200,000, itÂ’ll probably be the most expensive vehicle produced in the U.S. These spy shots give us an idea of what weÂ’re going to be looking at when the production SUV is finally revealed. Our first hint that this prototype is a Maybach is the grille. It looks suspiciously similar to the grille on the Vision Mercedes-Maybach Concept with all the vertical slats running down the big maw. Minimal camouflage is disguising the exterior for the most part, but we imagine Mercedes is hiding any of the gaudier parts of the car itÂ’d like to save for a big reveal. The exhaust outlets sure do look a bit different than the regular GLS, but the outside is generally the same as what we see today. As for the interior, thatÂ’s where most of the magic is expected to happen. A significantly overhauled look is inevitable, with the focus on even more luxurious materials than the most expensive norm-core GLS. A rear seat that's fit for a king or two is likely, along with Maybach-exclusive tech to boot. For now, we canÂ’t see in the heavily camouflaged and taped-off windows, leaving us to wonder about the luxury within. This Mercedes-Maybach is expected to compete with other massively expensive SUVs like the Bentley Bentayga or a fully decked-out Range Rover.  Everything thatÂ’s optional on the GLS should come as standard here, including the trick E-Active Body Control suspension. Look for a reveal coming in the not-so-distant future, as this prototype doesnÂ’t look terribly far from production to us.

Ford and Mercedes join Renault in French emissions investigation

The French government is investigating certain models from Ford, Mercedes-Benz, and Renault because they allegedly produce more nitrogen oxide than the country's pollution rules allow, according to Automotive News, citing a French newspaper. After VW's emissions scandal, French regulators began checking more vehicles for evidence of defeat devices and excessive real-world pollution. According to Automotive News, the Mercedes S350 allegedly showed inconsistent results across these tests, and a Ford C-Max had NOx levels five times over the limit. The Renault Captur crossover, Espace, and an unnamed utility vehicle also had results that were too high. The French testing for this investigation includes an on-road emissions check that's not part of the EU's normal evaluations, which some automakers claim is unfair. "Unofficial on-road testing has varying conditions and can produce significantly different results," a Ford of Europe spokesman told Automotive News. Renault representatives met with French officials on January 18 to explain the situation. The company later submitted a plan to recall 15,800 examples of the diesel Captur, and said it would offer a voluntary software upgrade for about 700,000 other vehicles, according to Automotive News. Representatives from Ford and Mercedes will meet with the government soon, too. Renault's stock price plunged last week after investors heard that French regulators searched three of the automaker's sites as part of the emissions investigation. The stockholders feared an environmental scandal like the one currently embroiling Volkswagen. There's one major difference – as of now, there's no evidence Renault equipped any of the polluting models with defeat devices. Related Video:
