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:

Why it's difficult to accurately test the efficiency of a plug-in car

When it comes to electric vehicles and plug-ins in general, the Environmental Protection Agency-certified range is a hugely important number. While actual range anxiety is largely psychological, the magic number does provide a point of comparison of buyers considering one EV over another. The driving distance is also often touted by automakers when marketing their models. Unfortunately, as Green Car Reports finds in a recent deep dive, the way the EPA calculates the figure is a convoluted mess, and discovering the reasons why is definitely worth the read. The issue isn't about bad science but instead comes down to vague wording. The EPA's accepted range test is sourced from an evaluation called J-1634 from the Society of Automotive Engineers, and it seems to provide balanced results for vehicles that automatically reach a single state of charge when plugged in. However for models with multiple charge settings, the situation gets complicated very quickly. Of course, these modes are often created in the software, meaning that a car's certified driving distance can change with just a few taps of the keyboard without the real world results owners might experience actually changing. By showing the test's effects on the certified range for the Tesla Model S, Nissan Leaf and Mercedes-Benz B-Class Electric Drive over the last few years, Green Car Reports makes a compelling argument that it's the evaluation that needs to change. Thankfully, it appears that the solution is a very simple one. Get the details here.

Here's today's round of auto plant closures in response to coronavirus

More automakers have shuttered factories, as businesses everywhere work to slow the spread of the Covid-19 coronavirus — and as the pandemic slows sales and disrupts parts supply chains. On Friday, the following closures were announced: • Volvo will close its factories in Sweden and the United States from March 26 to April 14. Volvo's U.S. facility, in Charleston, South Carolina, makes the S60 sedan. Its assembly plant in Torslanda, Sweden, turns out the XC90, SC60, and V90. Other Swedish facilities make engines and component parts. A Volvo factory in Ghent, Belgium, that builds the XC40 and V60 closed earlier this week and is expected to remain offline until April 6. Volvo's four factories in China have been reopened after a shutdown earlier this year. • Jaguar Land Rover announced that it will suspend production at its assembly plants in the UK over the coming week. The shutdown is expected to last until April 20. Elsewhere, production continues at the company's factories in India and Brazil, and JLR's joint-venture plant in China reopened at the end of February. • Bentley is closing its factory in Crewe, England, for four weeks, effective today. • Bugatti has put its atelier in Molsheim, France, on hiatus. No date was given for when assembly of its supercars might resume. • Mercedes-Benz on Monday will shut down its SUV factory in Alabama and its van assembly plant in South Carolina. Both will remain closed for a minimum of two weeks. Tesla yesterday revealed that it will suspend operations at its Fremont, California, vehicle assembly plant next week, on order from local officials there. Yesterday's factory closure announcements also included the U.S. assembly plants for Toyota (until April 6), Volkswagen (through March 29), Subaru (through March 29), and Hyundai (no time period specified). They join GM, Ford, Chrysler, Honda, Nissan, and Harley-Davidson, which earlier this week announced the suspension of production at their facilities.
