Infiniti parts ways with Red Bull Racing

The partnership between Infiniti and Red Bull Racing is done. The team announced that it will no longer run under branding from the luxury automaker and will drop the Infiniti name from its own. The shift is effective at the end of this year. Infiniti signed on as a sponsor of the Formula One team back in 2011 when Red Bull was at the height of its dominance and on the path to the second of four consecutive world championships. Two seasons later it stepped up to naming rights, with the team officially rebranded as Infiniti Red Bull Racing. But while the cars ran under motivation from the automaker's ally Renault, they stopped short of rebranding the engines as Infiniti's, leaving it in the unusual situation of being a title sponsor of (but not directly involved in) an F1 racing team. For next season, Red Bull will continue running the Renault power unit, albeit rebranded under the TAG Heuer name. In the process, the team will no longer have any branding from the French automaker or any of its associated brands. Meanwhile sister-team Toro Rosso is switching from Renault to Ferrari power for next season, while Lotus is prone to switch back to Renault engines and ownership. The French automaker also recently canceled its support of the feeder series known until now as Formula Renault 3.5. Infiniti has carried out only limited racing programs in its quarter-century history. Aside from the Red Bull partnership, it directly sponsored Sebastian Vettel up until his departure for Ferrari. The company also supplied IndyCar engines in the late 1990s, then sponsored the Indy Lights series for a few years. It recently helped a privateer team prepare a Q50 for the British Touring Car Championship, but otherwise hasn't had any top-tier factory racing programs to speak of. That makes it one of the few Renault Nissan Alliance brands (and Japanese automakers) not to actively participate in motorsports. Related Video:

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:

At long last, Infiniti plans a production EV

After years of false starts, it appears that Nissan's Infiniti division will finally launch a production electric car in 2019 and debut it as a concept in January at the North American International Auto Show in Detroit. Details at this point are scant, but Infiniti Executive Design Director Alfonsa Albaisa told Autocar the EV would be an all-new electric-only vehicle based on a new platform. Citing the company's grand prix-inspired Prototype 9 racecar concept that was shown a few weeks ago at Pebble Beach, Albaisa said consumers would see "parts of the car in a different context" on the concept EV. The Prototype 9's all-electric powertrain was developed by parent company Nissan's Advanced Powertrain Department. The last we saw of any electric offering from Infiniti was way back in 2012 with the LE Concept sedan, which was supposed to show up in dealerships two years later. Those plans were initially postponed in 2013 and then again in 2015 amid doubts over EV sales projections and larger concerns over boosting overall Infiniti sales. The LE had a 24 kWh lithium-ion battery pack paired with a 100 kilowatt electric motor delivering 134 horsepower and 240 pound-feet of torque.
