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-AMG GT pressed into service as DTM safety car

DTM is one of the most competitive, fast-paced touring car series in the world. So to set the pace, the marshals need a pretty fast car as well. And that's just what they got with the new Mercedes-AMG GT pictured here. Marking its debut at the Lausitzring speedway this weekend, the AMG GT S safety car is based closely on the road-going model, but like the version that's already in use in Formula One, it's been modified for safety-car duty. That means a low-profile light bar mounted to a carbon-fiber air scoop on the roof – both tested in a wind tunnel – as well as the front splitter and rear wing from the optional Aerodynamics package, and the optional upgraded rolling stock. Inside it's got racing buckets, six-point harnesses, a flat-bottom steering wheel, and special radio equipment. Otherwise it's essentially the same as the road-going model, right down to the 4.0-liter twin-turbo V8 and seven-speed dual clutch transmission. After all, with 510 horsepower on tap, it ought to be able to stay out ahead of the 490-hp touring cars currently competing in DTM. The new safety car replaces the C63 AMG Black Series coupe that Mercedes previously contributed to the effort, and will alternate with the vehicles furnished by rivals Audi and BMW from race to race.

A new Safety Car celebrates its DTM premiere: at the second DTM race at the EuroSpeedway Lausitz (29 to 31 May 2015), the Mercedes-AMG GT S is set to be deployed for the very first time. The new sports car will help to ensure maximum safety on the race track in the world's most popular touring car series. In technical terms, the 375 kW (510 hp) eight-cylinder sports car is for the most part the same as the series production vehicle – just like its counterpart from the FIA Formula 1 World Championship™, the Official Safety Car. In its road-going guise the Mercedes-AMG GT S has turned heads since its market launch in March 2015 and now the sports car is also taking to the DTM stage. The new season of the German Touring Car Masters (DTM) got under way during the first weekend of May in Hockenheim. The second DTM race taking place at the EuroSpeedway Lausitz at the end of May will see the Mercedes-AMG GT S make its first appearance as the official Safety Car.

Mercedes-Maybach Ultimate Luxury SUV concept shown in leaked images

Just days ago, we posted the interior teaser image Mercedes-Maybach released of its Ultimate Luxury concept due to be presented at the Beijing Motor Show. Now photos of the entire vehicle, inside and out, have leaked online courtesy of the manufacturer. Thanks to the concept's own microsite being live for a short while, we've gotten a good look of the concept. And it's not just a dressed-up GLS by any means, even if there might be a GLS platform underneath it all: It's a high-riding four door sedan with a clearly formed trunk instead of a traditional SUV shape. There's a big waterfall grille flanked by low, aggressive three-unit headlights, and the detailing is a combination of SUV cues and something a lot more luxurious. It's not easy to design a three-box sedan that's still recognizably an SUV. Inside, there's white leather and rose-gold detailing everywhere. But the big deal is the powertrain, which in the concept is all-electric. The all wheel drive is propelled with four electric motors, with a combined power output of 750 horsepower. The battery, said to be a flat underfloor design, is good for 80 kWh and an EPA range of over 200 miles, and the vehicle's top speed is limited to 250 km/h, or 155 mph. There's DC fast charging at up to 350kW, meaning that the range can be boosted by 60 miles in just five minutes, and induction charging is also available. All in all, the vehicle reminds us of the 2009 Lagonda Luxury Utility Vehicle concept, which was also created around a three-box sedan shape and also based on a Mercedes platform, GL-Class in that case. It did not yield a production version, but maybe the Vision Ultimate Luxury will.
