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 SUV concept headed for Beijing reveal in April

Mercedes-Benz has toyed with the idea of a Maybach SUV for at least 11 years. According to Autocar, we'll finally see a concept with production intent at the Beijing Motor Show next month, the luxury SUV slated for market release next year. As has been the rumor for at least six years, the Maybach people carrier will be based on a stretched version of the GLS, which moves to the company's new Modular High Architecture with the 2019 model. Back in 2007 when Maybach was its own brand and selling roughly 300 units per year, Car magazine reported that brand chiefs were interested in convertible versions of the Maybach 57 and 62 sedans, and an SUV. Maybach built a one-off concept based on the GL — the former GLS-Class — in 2009, but never took the idea further. The rumor popped up again in 2014, then in 2015, reaching not-if-but-when status early last year. A decade on, it's finally time to play the hand. Even though the super-luxe SUV would sit on a stretched version of what is already a three-row SUV, it's reasonable to expect the Maybach SUV will only get two rows. That would give designers plenty of extra room for seating luxury and amenities even beyond the S-Class Maybach. On the other hand, if Mercedes sticks to the rough Maybach playbook so far, a triple-row Maybach would be the only such SUV in the mid- to upper-six-figures. The S-Class 560 4Matic starts at $102,990, the S 560 4Matic Maybach starts at $168,600. Applying that spread to the $94,500 GLS 550, you'd land around $160,000 before adding the markup for a new generation. That kind of starter pricing might make a great tweener proposition. Mercedes could focus on a range of buyers who want to go upscale from the $125,300 AMG GLS 63, without needing to worry — yet — about challenging Bentley and Rolls-Royce. Power is said to come from some version of the company's oft-applied 4.0-liter twin-turbo V8 that puts out 462 horsepower in the S 560, but the 3.0-liter inline-six hybrid in the S 560e is under consideration. We'll know next month, when the lightly veiled concept takes the stand in China. The full-on production version should get an introduction at this year's L.A. Auto Show. Related Video:

Mercedes-Benz Vision Tokyo concept shows us our lazy future

The first autonomous vehicles to hit the road will likely look much the same as the ones we drive currently. But as self-driving technology evolves, so too will the shape of the vehicles themselves. And this is what Mercedes figures that future could look like. The Vision Tokyo concept, so named for the show now ongoing at which it's been unveiled this morning, is an odd yet forward-looking shape, rendered in Alubeam silver and glowing blue. Power comes from a hybrid hydrogen fuel cell and inductive electric charging system that give it a theoretical zero-emissions range of over 600 miles. One look at the lozenge-like shape should tell you that the design is all about the interior space. The driving station – should it be needed – offers a clean dashboard with HUD-only instruments and a central driving position with unobstructed view through the wraparound windscreen. The cabin is clearly focused, however, on the lounging occupants more than on the driver. Accessed via a single, giant gullwing hangar door, the approach is closer to that of a mobile lounge space than a traditional automotive interior, with a wraparound sofa, some manner of high-tech 3D game projected in the middle, and a wide infotainment screen on the inside of the door. The concept clearly foretells of a different future – one that demands less of the driver and offers more relaxed comfort. So while the driver within us grows concerned at his numbered days, the rest can't help but be strangely intrigued. Scope out the live images from the floor of the Tokyo Motor Show and share your thoughts on the concept in the Comments section below.
