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-Benz CLA45 AMG coming to the New York Auto Show

Mercedes-Benz showed off the CLA45 AMG at a private event on the eve of the Geneva Motor Show, but was determined not to let it be photographed. We can talk about it, though - after all, a teaser image was released to promote the new Sony game Drive Club. The CLA45 AMG will use the same powertrain as the A45 AMG, which means a 2.0-liter turbocharged four-cylinder with 360 horsepower and 332 pound-feet of torque. And that means a small four-door coupe sedan with the highest horsepower-per-liter in the segment. It will shift through the same seven-speed dual-clutch transmission, should also run out of speed at 155 miles per hour and have that three-stage stability control system.
As with its hatch sibling, the CLA is already so aggressive on the outside - and the parent company so anxious not to demolish the sedan's 0.22 coefficient of drag - that not much has been done to the cranked-up CLA. Even the rather thin tires on the standard only get a little less thin on the hotter variant. Inside will be the telltale AMG signs, with lots of red detailing and that flat-bottomed wheel among the giveaways. We'll know more later this month when the wraps come off at the New York International Auto Show.

Mercedes G500 4x4 rumbles into view

Mercedes keeps raising the bar with the G-Class: just when you think the legendary Gelandewagen couldn't get any more hardcore, it mashes the throttle and does exactly that, plowing through a bank of snow, sand, hell or high water in the process. What you see here is the latest. It's called the G500 4x42. Aside from the various engine specs, the G-Class has been offered in a number of body-styles. Right around the same time that the two-door convertible was discontinued, Benz rolled out the indomitable G63 AMG 6x6 – a half-million-dollar, six-wheeled monster truck powered by Affalterbach's 5.5-liter twin-turbo V8. Evidently enough people liked the idea but didn't see the point in that extra set of wheels, so Mercedes has toned it down – just a little – but kept the high-riding suspension. The result is the truck we've seen testing a couple of times now in a bright shade of Hulk green, and which is now just about ready for its debut. On the scale of extreme G-Wagens, it slots in between the standard model and the 6x6, keeping the jacked-up suspension and giant wheels, but losing the extra axle. The G500 moniker also indicates that it'll at least be available with the 382-horsepower, naturally aspirated, non-AMG version of the 5.5-liter V8 that we'd know as the G550. Just how much of a premium Benz will charge for the beefed-up version, we don't know, as further details are set to be released next week ahead of a likely debut in Geneva. But hopefully it'll be closer to the $115k it gets for the standard version than the $500+k the 6x6 goes for.
