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 to phase out 5.5-liter V8 after next year [UPDATE]

UPDATE: A previous version of this story indicated that AMG's 6.0-liter twin-turbo V12 was still mated to a five-speed automatic transmission, however the latest models (including the S65 AMG sedan and coupe, SL65 roadster and G65 sport-ute are equipped with the newer seven-speed unit. Mercedes also reached out to point out that the 5.5-liter engine will be phased out gradually, not overnight. There's a lot to love about AMG's 5.5-liter twin-turbo V8. It produces as much as 577 horsepower and 590 pound-feet of torque, and delivers blistering performance to even the heaviest of vehicles. But try not to get too attached, because like its 6.2-liter, naturally aspirated predecessor, it's not long for this world. The latest word comes from Autocar, which reports that Mercedes will release the last applications for the 5.5 biturbo within these next two calendar years in the new GLE63 AMG and upcoming S63 AMG convertible. After that, even though it was only introduced in 2011, it will be phased out. Fortunately Affalterbach has a worthwhile successor already in place in the 4.0-liter twin-turbo V8 from the Mercedes-AMG GT. The smaller powerplant, already in store for the new C63, is already producing 503 hp and 479 lb-ft in S spec. That's still shy of the larger unit's output, but where the 5.5 is nearing the end of its production cycle, the 4.0 is just starting out. Of course the 4.0-liter biturbo isn't the only engine AMG is making these days. Smaller models (based on the front-drive platform) employ the 45-designation, high-output 2.0-liter turbo four. Models at the very top of the lineup, however, use a 6.0-liter twin-turbo V12 that may be a dinosaur, but with 621 hp and 738 lb-ft of torque on tap, still can't be beat.

2021 Mercedes-Maybach GLS 600 First Drive | Fat cat money

ANN ARBOR, Mich. — Do you like the Mercedes-Benz GLS-Class, but just donÂ’t think itÂ’s fancy or expensive enough as it is? Maybe the AMG version is too audaciously sporty or you'd prefer a completely different flavor of garish. Maybe you donÂ’t want to be seen driving the GLS at all. If youÂ’re looking for the perfect GLS to be driven in, but need to make sure you look more like the type of fat cat to blow money on lavish, boozy dinners and decorative fountains than the pro baller who splurges on a home gym and tennis courts, Mercedes finally has the giant SUV just for you: the Mercedes-Maybach GLS 600. Is this tongue-in-cheek straw man in any way indicative of an actual Maybach owner? Who knows. We can barely comprehend how rich someone might be who can afford this $161,525 ultra-luxury SUV (before any options) let alone actually know someone of such largesse. Nevertheless, the GLS upon which it's based is certainly no stranger to us. We first drove the GLS 470 in Austria's Tyrolean Alps, sampled the AMG GLS 63 in the Columbia River Gorge, and nominated its bouncy E-Active Body Control suspension for AutoblogÂ’s 2020 Technology of the Year Award. Most of the same ingredients are present in the Maybach 600, but just one look at this two-tone luxury liner requires you to rethink the scope of what the GLS can do. While the overall body style looks more or less the same, there was no mistaking our tester for an ordinary GLS, or even an extraordinary AMG model. The two-tone paint — Lunar Blue Metallic below, and Iridium Silver Metallic from the beltline up — shouts to passersby (in an aristocratic German accent, presumably) that thereÂ’s something different going on here. The optional wheels, which get their own Maybach design, measure an absolutely massive 23 inches. Perched on the nose is the nearly extinct Mercedes hood ornament. The final giveaway comes when you move in a little closer and see the Maybach badging on the grille, tailgate and D-pillars. But seriously, that paint job is something else. The exterior doesnÂ’t quite do justice to what awaits within. The driverÂ’s door opens to a rich, inviting and clearly technologically advanced cockpit. The dual screen dash housing the instrument panel and infotainment touchscreen is becoming familiar from GLS down to GLA, as are the multitude of controls on the wheel and center console with which one can easily interact with them.
