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:

Nissan edges out Tesla for most ZEV credits sold in California

When it comes to California zero-emissions vehicle (ZEV) credits last year, Nissan was selling and Mercedes-Benz was buying. The California Air Resources Board (CARB) put out its ZEV-credits numbers for the year that ended September 30, which is why we now know that Nissan, maker of the battery-electric Leaf, transferred 663.6 ZEV credits out of its account last year. That just edged out the 650.195 credits that Tesla sold. Chrysler's Fiat affiliate was a distant third, but its limited-production Fiat 500E was still able to generate some ZEV credits and then transfer out 235.2 of them. We don't know how much the buyers paid for these credits, since those details are kept private. It's an ever-changing rulebook over at CARB, anyway. On the flip side, Mercedes-Benz had to buy 663.6 ZEV credits in order to comply with clean vehicle-sales mandates in the most populous US state, indicative of the German automaker's gas-guzzling tendencies. Honda has cars that get better fuel economy than your average Benz, but its plug-in vehicles represent just a fraction of total sales and so it had to shell out for 542.5 ZEV credits. Chrysler-Fiat basically tread water, since the 237.8 ZEV credits it required for compliance canceled out gains on the other side of the ledger. Those Dodge Ram pickup trucks don't exactly help matters. Last year, Tesla sold the most ZEV credits while GM purchased the most. Overall, Californians bought about 3.5 million vehicles for the year that ended September 30, including 38,000 battery-electric vehicles, 30,000 plug-in hybrids and 570,000 conventional hybrids. The longstanding ZEV program means that California now has more than 100,000 ZEVs on its roads. Read this for more details on ZEV credit transfers in California.

Mercedes fits new C-Class with AMG kit

It's only been a week and a half since Mercedes-Benz revealed the new C-Class, and it'll likely be a while yet before the replacement for the C63 AMG comes along. But if you want to see a preview of what it'll look like, look no further than the AMG aero kit that has just surfaced.
Expected to debut on the new C-Class at the fast-approaching Detroit Auto Show, the AMG Line Exterior Pack adds a new bumpers front and rear, side skirts, dual exhaust tips, mesh grille, aluminum window frames and - most importantly - 18-inch alloys packing upgraded brakes and fitted to a lowered sport suspension. All of which will help any C-Class look the part, even if the engine remains stock.
