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:

2019 BMW X7 vs luxury SUV rivals: Comparing specs and photos

Today we get our first-ever look at the first-ever 2019 BMW X7 crossover. We've actually already had our first-ever drive in an X7 Prototype. And so, we thought it appropriate to follow that up today with the first-ever X7 comparison of specs between BMW's first-ever three-row crossover with legitimate room for seven and its many high-dollar competitors. On paper, the 2019 X7 definitely seems to most closely align with the Mercedes-Benz GLS-Class. Their similar dimensions, interior space, engine choices and price would certainly imply where BMW placed the target when developing X7. We used those same elements to determine three-row vehicles likely to be cross-shopped or that should be cross-shopped. These include the Audi Q7, Land Rover Discovery, Volvo XC90 and Lincoln Navigator. Yes, the latter is a truck-based SUV as opposed to a crossover, but tell that to all the people lining out the door at the local Lincoln emporium. They do not care, and neither shall we. We also included the 2019 BMW X5, which was completely redesigned for this year and therefore not the first-ever. That makes it less appealing? Either way, lining the new X5 up with the SUV that leapfrogs it atop BMW's SUV hierarchy should provide a good idea of just how much more you get by going up a model number. Engines and model lineup Again, the X7 aligns closest with the GLS, offering a base six-cylinder in its xDrive40i model and an upgrade turbo V8 in the xDrive50i. The Mercedes engines have greater output, but the GLS still accelerates slower than the BMW. As the 2019 X5 offers the exact same engines, we would also expect the X7's fuel economy to be superior to the GLS once its estimates are announced. It should be noted, though, that the GLS offers a high-powered AMG model whereas we anticipate the X7 to offer a plug-in hybrid model comparable to the X5 upcoming xDrive45e model. The other luxury SUVs diverge in their engine choices and model lineup. The Audi Q7 offers a base turbocharged four-cylinder, as does the Volvo XC90 in its T5 model, which we left out of the above chart entirely for space reasons. That the Q7 3.0 TFSI supercharged V6 gets the same fuel economy estimates as the four-cylinder is proof positive that engine is purely around for its lower base price.

Rain prolongs the Championship battle | 2016 Brazilian Grand Prix recap

Rain and an old-school circuit are the antidotes to Formula 1's constricting technical regulations and Tilke tracks. At Brazil's Autodromo Jose Carlos Pace – otherwise known as Interlagos – rain Saturday night and on race day washed away everyone's careful plans, except for those of the man at the front of the pack. Lewis Hamilton put his Mercedes-AMG Petronas ahead of the field throughout the weekend. On Sunday, a storm-delayed start behind the Safety Car assured Hamilton of a clean path to the lead and a clear track. The Briton didn't waste it, pulling out a gap on teammate Nico Rosberg behind, and Rosberg appeared to have no interest in going hard after Hamilton. Safety Cars and red flags kept resetting the gap to zero, though. After the Mercedes-AMG GT S led the first seven laps, it emerged again on Lap 13 for another six laps when Marcus Ericsson crashed his Sauber. Seconds after racing resumed, Kimi Raikkonen aquaplaned his Ferrari into the wall on the front straight. That caused the first red flag, leading to another eight-lap Safety Car interval, then a second red flag stoppage due to conditions on Lap 28, then three more Safety Car laps, and then, finally, racing again. Hamilton never surrendered his lead. The Briton changed tires once during a stoppage, and drove fast enough to cover the full race distance despite the intermissions. Afterward, he said "it was a very easy race." Rosberg had it harder, defending against the preternatural Max Verstappen in third. Barring misfortune it's already clear the Red Bull pilot has at least one Driver's Championship in his career future. In Brazil the young Dutchman drove like he's worthy of the hardware right now. After Verstappen passed Rosberg for second on Lap 34, the Red Bull driver pitted for intermediate tires on Lap 44 – a huge gamble in the conditions – coming back out in fifth. That tire wager failed, giving Rosberg a safe position in second when Verstappen had to pit for extreme wets on Lap 54 of 71. The teenager re-emerged in 16th. Over the race's final 17 laps Verstappen passed 13 drivers at six different places on track. He ran it close-but-clean a couple of times, especially when getting around Sebastian Vettel and Sergio Perez, but he was simply untouchable. Not only did the Dutchman score an amazing third place, he put in what could be the drive of the season.
