2016 Chevy Volt will not need premium gas

Buried in the new technical details of the 2016 Chevy Volt released yesterday was a throwaway line about a small but important change that's due to the new 1.5-liter, four-cylinder engine. The first-gen Volt has always required premium gas but the new powerplant will be happy burning plain old regular. The Volt's chief engineer, Andrew Farah, told AutoblogGreen that the change was due to today's Volt owners explaining they were not happy paying for top-shelf petroleum. "The ability to use regular unleaded was based directly on customer feedback," he said. "Since the range extender is an all-new engine, it was optimized to use regular unleaded at the outset. Using regular fuel will not have effect on vehicle acceleration or other performance factors." As Larry Nitz, GM's executive director of vehicle electrification, told AutoblogGreen yesterday, the new engine is more powerful and quieter than the outgoing 1.4-liter engine that's used in the current Volt. Fuel economy and EV range specs for the next-gen Volt are not expected until the full car is revealed at the Detroit Auto Show in January.

NHTSA approves hybrid rearview mirror display in Cadillac CT6, Bolt EV

The Chevy Bolt EV prototype doesn't just have a fancy new all-electric powertrain. Just outside the driver's line of sight is a newfangled rearview mirror, one that can turn into a screen that shows a moving image from the rear-facing camera. Speaking to NPR's Robert Siegel yesterday, Department of Transportation secretary Anthony Foxx said that NHTSA has now approved this type of mirror/screen for use in vehicles. According to a letter from NHTSA to General Motors, GM will likely use this Full Display Mirror first in the 2016 Cadillac CT6 before coming to the Bolt. In its letter to GM, NHTSA said that the Full Display Mirror will only qualify as a standard rearview mirror as long as there are normal side mirrors in place. In other words, don't expect to see cameras and screens replacing all the mirrors in a motor vehicle just yet. @AutoblogGreen @NPR - #NHTSA has OK'd GM rear-view system that can switch between mirror & camera views. pic.twitter.com/6CBeIit10v — Anthony Foxx (@SecretaryFoxx) February 22, 2016 The Full Display Mirror was developed by Gentex, which has long worked with GM. The FDM debuted in 2014 and some people hoped it would also make its way into the Tesla Model X. Gentex, which also makes auto-dimming mirrors, says that it has "set out to develop the technologies and core competencies necessary to manage this evolution of the rearview mirror." The Chevy Bolt EV will start at $37,500, before incentives. The 200-mile EV will go into production late this year for likely sale in early 2017. Related Video:

Conquest and controversy conclude the 2014 Rolex 24 at Daytona [spoilers]

If you don't wish to know who won the 2014 Rolex 24 at Daytona, you should avert your eyes right now. We'll even give you a double-space to skedaddle...
For those of you still with us, the first race in the United SportsCar Championship (USCC) is done, but the discussions about it certainly won't end for a while. Daytona Prototypes claimed the first four overall places, the top spot taken by the No. 5 Action Express Coyote-Chevrolet Corvette DP driven by Joao Barbosa, Christian Fittipaldi, Sebastien Bourdain and Burt Friselle. The 16th and final caution of the race bunched the field up for an eight-minute sprint to the flag, so the first place getter finished just 1.4 seconds ahead of the No. 10 Wayne Taylor Racing Dallara-Chevrolet Corvette DP driven by Max Angelelli. Third place went to Brian Friselle in the No. 9 Action Express Chevrolet Corvette DP, 20 seconds down. Chevrolet power hasn't taken the overall win since 2003, eleven years later it scores a one-two-three-four. The No. 6 Muscle Milk/Pickett Racing ORECA-Nissan 03 scored fifth place, the top LMP2 finisher.
The Prototype Challenge class win went to the No. 54 CORE Autosport team of Colin Braun, Jon Bennett, Mark Wilkins and James Gue.
