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:

2016 Formula 1 Chinese Grand Prix recap: another wild show on and off track

Normally we use this space to provide a lengthy recap of the weekend's Formula 1 race, but we're going to try something different since most folks reading this know what happened at the Shanghai International Circuit on Sunday. Instead, we'll alight on what we saw as the big issues in and around the race. Let us know what you think in Comments. Proper qualifying is back. Thank goodness. It only took a month of embarrassment to fix it. And so is passing! For the third race in a row, big performance improvements at the ten teams behind Mercedes-AMG Petronas and a wider tire selection at this race graced us with opening stints filled with dicing cars. Seeing the McLarens on screen doesn't make us cringe. Manor doesn't only make the global feed when it's being lapped. We've been complaining about parade races for so long that we forgot excitement was possible without rain or wholesale regulation changes. Yes, Mercedes is still the king of the jungle, but there are some other proper midfield beasts on the hunt, too. Malfunctions up and down the grid did help the show in Shanghai, like Lewis Hamilton suffering perpetual troubles, Nico Hulkenberg's runaway front wheel which red-flagged Q2, and Sebastian Vettel's and Kimi Raikkonen's flubbed hot laps in Q3 that let Daniel Ricciardo slip by into second on the grid. Come race day things went all Grand Theft Auto at Turn 1 on the opening lap, sending some of the best cars to the pits. Then came Ricciardo's puncture while leading, then came the Safety Car – all by Lap 5. Nico Rosberg got 38 seconds of airtime on the way to victory – at the start and the finish, and that happened to be his margin of victory, too – otherwise he was a ghost. Everyone else was struggling and juggling. Rosberg's win at the Bahrain Grand Prix put the German at five consecutive victories going back to last year's Mexican Grand Prix. The history books show that any driver who's won five straight contests has gone on to win the championship. With his triumph in China, the German has won the season's first three races, the history books again show that the other nine drivers who've pulled that off have gone on to win the championship. Rosberg, 36 points ahead of his teammate in the standings, is having none of it. He said of the other victors, "But they didn't have Lewis Hamilton as their team-mate." Perhaps Mercedes was right not to make an engine deal with Red Bull last season.

Luxury car brands scrambling to avoid a blue Christmas

DETROIT — When financial markets surge to new records, sales of luxury cars usually rise, too. Instead, October U.S. auto sales reports on Wednesday showed that a collapse in sales of luxury sedans is accelerating. Consumers have gradually shifted over to luxury sport utility vehicles from sedans in the past decade, but the trend — which has occurred in both the non-luxury and luxury sedan segments of the auto market — was particularly pronounced in October. Sales of Daimler AG's Mercedes-Benz S-Class, long a global benchmark for large, premium sedans, plunged 49 percent in October, and are down 24.8 percent for the year to date. General Motors' Cadillac brand said it sold just 779 of its CTS sedans in October. Demand for that car, designed to compete with German luxury sedans, is down nearly 33 percent for the year. "There's still a significant portion of the market that wants a car, but I'm sure there were people who preferred a horse to a car at one point." Cadillac's best-selling model this year is the XT5 compact SUV, which has more than doubled sales from a year ago. The shift within the luxury vehicle market away from sedans toward SUVs of all sizes is forcing some of the most prestigious brands to scramble to add SUV models to their lineups or boost SUV production to meet demand. "In the short term, there will be pressure to add (consumer) incentives, cut production or both," said Cox Automotive analyst Michelle Krebs. "And we just don't see an end in sight to this trend." The Dow Jones Industrial Average has been trading at all-time highs, usually a good sign for luxury sedans, but as major automakers reported new U.S. vehicle sales for October on Wednesday, sales for passenger cars continued their slide while luxury SUV and crossover sales rose again. According to Kelley Blue Book data, in 2007 luxury sedans made up 7.6 percent of U.S. new vehicle sales, while luxury SUVs made up 4.2 percent. Through September this year, luxury SUVs made up just over 7 percent of the market, compared with 4.9 percent for luxury sedans. In the short term, luxury brands could use holiday season sales promotions to clear slow-selling sedans off dealer lots, analysts said. Toyota's Lexus brand said on Wednesday it will launch its "December to Remember" year-end sales promotion for the 18th straight year.
