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:

The most or nothing: Mercedes-Maybach S650 Cabriolet pushes the luxury limits

After the introduction of the Mercedes-AMG GT Roadster at the Paris Motor Show this fall, we informed you that Mercedes-Benz has a convertible conundrum, a surplus of drop-tops that seemingly threatens to self-cannibalize within the brand's ever-proliferating lineup. Benz's head of design, Gorden Wagener, who spends much of his time in Southern California, argues it's not a problem: Each convertible, in its ideal construction, would intrinsically vanquish any issues. "The bad is the enemy of the good," he said, not exactly quoting Nietzsche. Now, the three-pointed star brand has upped the top-down ante, with the unveiling this week at the Los Angeles auto show of the Mercedes-Maybach S650 Cabriolet, a vehicle so opulent, it sits in price and position atop the uber-luxury brand's current top-of-the-line offering, the $247,900 Mercedes-AMG S65 Cabriolet. View 24 Photos "Mercedes-AMG is our performance brand so it's all about performance stuff," says Wagener in a one-on-one interview on the roof of a Beverly Hills mansion just before the new car is unveiled. "Of course, Maybach has power, too, but it's the ultimate in luxury. So it's more on that side. And for me in the interior, it's the haute couture of the automobile, so we tried to up that a little more with details. And on the exterior, it's a more superb appearance up front, more chrome, more rich, and of course we tried to up that branding even more. The S-Class is the best car in the world, we consider, I always thought we could raise the Mercedes brand. And it's the same with the S convertible." Why does Mercedes-Benz need a flagship atop its flagship? Because, when climbing the mountain of automotive luxury there is always the customer who, when he or she reaches the pinnacle, wants more. A car brand, especially one with deep pockets and luxurious heritage like Mercedes, can always further gild the automotive lilies, creating a step up for those for whom the brand's motto, The Best or Nothing, is a literal life credo. "It's always our job to make it better," Wagener says. "Each little detail, the wood, the wood under cover of the cabriolet, the leathers. All the super luxury details that make a luxury car into a super luxury car. The key is to make a modern luxury design and not a traditional luxury design. There is definitely a market for traditional luxury, but we always wanted to have Mercedes, Maybach in particular, as a modern luxury car.

Mercedes out to defend its F1 crown with new W06 Hybrid Silver Arrow

They say there's only one way to go when you're on top, and that's down. That's the direction in which every other team on the Formula One grid will be trying to push Mercedes this season, but the defending champions will be doing their best to stay on top. What you see here is the embodiment of that effort. After taking pole position at all but one race last season, the checkered flag at all but three and an impressive dozen one-two finishes, the new Mercedes AMG F1 W06 Hybrid will have one heck of an act to follow. In accordance with the only major change to the sporting regulations for 2015, the most obvious difference over last year's W05 is the revised front end, but the team insists it worked hard over the winter to optimize everything underneath that silver and teal bodywork, from the suspension to the turbocharged hybrid power unit and everything in between. One of only two teams (alongside Ferrari) on the grid this season to develop its own engine in-house, the Mercedes PU106A proved practically unbeatable last season. And with engine development all but completely frozen in the off-season, its innovations are likely to prove just as insurmountable this year. But as team principal Toto Wolff puts it, in quoting Babe Ruth, "Yesterday's home runs don't win today's games." While nothing's for certain in one of the world's the most competitive arenas, chances are still high that Mercedes will continue to dominate this season just as it did the last. The most gripping battle, then, may very well be waged once again between Lewis Hamilton and Nico Rosberg, whose rivalry started long before either got their start in F1, from karting and up through the ranks of the lower formulae. Though Lewis was just crowned world champion for the second time, Nico has been with the Mercedes team for longer, has been in F1 for longer and didn't give up on chasing Lewis all of last season – so don't expect him to this year, either.
