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:

Volvo S60 Polestar concept plays in the snow with Mercedes C63 AMG

Chris Harris took to a snowy stretch of tarmac to get a fingertips-on-the-wheel feel of the Volvo S60 Polestar concept. Harris says the turbocharged sedan with 508 horsepower and 424 pound-feet of torque - and a manual transmission - is "a study to see if Volvo can get back into the fast-car market." The Polestar S60 concept, one of which was already purchased for $300,000 by a private buyer, is still making the publicity rounds because even Volvo's Chinese owners realize that, as Harris says, "Volvo sold more cars because it made fast cars" like the old 850 T5 Wagon that stormed the British Touring Car Championship in the 1990s.
For reference, Harris compares the blue wonder to the Mercedes-Benz C63 AMG and its 487 hp and 442 lb-ft. The question is, were Volvo to get the price of a production version of the S60 Polestar to climb way down from its 200,000-pound sticker, could it be worthy competition to the established giants?
You can watch Harris divine the answer via a lot of drifting through the snow and a drag race in the video below.

Recharge Wrap-up: 2015 Honda CR-Z now on sale, Daimler and Linde building hydrogen stations in Germany

The 2015 Honda CR-Z hybrid is now available at dealerships, for slightly more money. The CR-Z starts at an MSRP of $20,145 (plus $790 in destination charges), up from the $19,995 price of the 2014 model. For those who don't want to row their own gears with the six-speed manual transmission, the available CVT adds an extra $650 to the price, but also offers better fuel economy, especially in the city. The manual-equipped CR-Z gets 31 mpg city/38 highway/34 combined, while the CVT version is rated at 36/39/37 mpg. The 1.5-liter engine and electric motor provide a combined peak 130 horsepower. The manual CR-Z offers 140 pound-feet of torque, with the CVT version providing 127 pound-feet. Customers can also soup up their new CR-Z with upgrades (including a supercharger) from Honda Performance Development. Learn more in the press release below. Daimler and Linde are teaming up to build hydrogen fueling stations in Germany. The automaker and gases and engineering company, with the help of a few oil and gas companies, plan to install 13 new stations by the end of 2015. The installations precede a push by Daimler to get more fuel cell vehicles on the road. "From 2017, we are planning to bring competitively priced fuel-cell vehicles to market," says Daimler's Herbert Kohler. "So now is the time to build a nationwide fuelling infrastructure." Linde will supply the stations with fully renewable hydrogen. Read more in the press release below. In 1899, an EV set a world landspeed record, and Wired has revisited the story with a nice look back at the "La Jamais Contente" and its driver, Belgian engineer Camille Jenatzy. Jenatzy built an electric car to race in a hillclimb, which he won while clocking a top speed of 17 miles per hour (measured the old-timey way - without radar guns). Just a few weeks later, another man set a landspeed record of 32 miles per hour, beginning a back-and-forth series of setting new records. Then, on April 29, 1899, "The Red Devil," as Jenatzy became known as, surpassed 100 kph (62 mph) when his torpedo-shaped electric car set a record of 65.8 mph. It was powered by two 25-kilowatt electric motors. Read the whole story over at Wired.
