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.

New Corvette Feature Keeps An Eye On Valets

Face it. If you own a luxury or sports car, whenever you hand the keys to a valet, you imagine the car going on a high-speed joyride like the Ferrari in the 1980s cult movie "Ferris Bueller's Day Off." Now, General Motors has an option on the 2015 Chevrolet Corvette that takes those worries away. The latest version of the sports car, due out in September, has a feature that records where the car goes with a camera mounted in the windshield trim. It also captures audio in the cabin as well as speed, engine revolutions per minute, gear position and G-force. That all helps the car tattle on any valet who doesn't take a slow, direct route to a parking space. GM says it's the most extensive attempt by an automaker to thwart valet joyriders, although it's not the first. The automotive website Edmunds.com says Hyundai and Mercedes offer "geofencing," a feature that sets a perimeter and then notifies the owner's smart phone if a car goes beyond it. Chrysler has a valet mode that caps engine speed and horsepower, while Audi lets owners limit engine speed for valets. With the Corvette, once the owner activates the feature with a four-digit code, the touch screen tells the driver it's in Valet Mode. But it doesn't warn the valet that he's being recorded. The feature also locks the glove box and a storage compartment in the dashboard and shuts down the infotainment system. Valet Mode started off as a performance data recorder for those who take their Corvettes on the racetrack. GM engineers quickly figured out that it had more uses. "Think of it as a baby monitor for your car," Corvette Product Manager Harlan Charles said in a statement. "Anyone who has felt apprehension about handing over their keys will appreciate the peace of mind of knowing exactly what happened while their baby was out of sight." Data and video from the valet mode can be viewed instantly by the owner on the car's 8-inch color screen when the car is parked, or it can be downloaded to a computer. The system could go into more mainstream models if feedback is good on the Corvette, GM spokesman Monte Doran said. The feature is paired with a navigation system and costs $1,795. A 2015 Corvette starts at just under $54,000. Chevrolet Technology Gadgets

Race Recap: Rolex 24 at Daytona was fast and feisty

Let the record show that victory at the 2015 Rolex 24 at Daytona went to the No. 02 Chip Ganassi Racing with Felix Sabates Target/Ford EcoBoost Riley DP driven by Verizon IndyCar drivers Scott Dixon and Tony Kanaan and NASCAR drivers Jamie McMurray and Kyle Larson. The winner did 740 laps to cover 2,634.3 miles in 24 hours and 57.667 seconds. That's a statement to this year's pace in spite of 18 cautions, two more than last year: the Michael Shank Racing Ligier got pole with a time of 1:39.194, slower than last year's pole time of 1:38.270; however, the winning car last year only did 695 laps. The fight for top honors was shaved to a four-car battle over the first third of the event. The No. 02 Ganassi car took the lead on the first lap, swapping it well into the night with the No. 01 Ganassi car, the No. 10 Wayne Taylor Racing Corvette DP, and the defending champion No. 5 Action Express Corvette DP, all of them staying within about 20 seconds of one another. The Action Express car had a fuel connector come loose and lost three laps getting towed back to the pits to have it reattached, but was back in the lead 18 hours in. The No. 01 Ganassi car dropped out with recurring clutch problems 22 hours in, retiring not long after. A race-within-the-race is where the concluding action happened, a seven minute, 30-second dash from the end of the last caution to the checkered flag. During the penultimate pit stops with an hour to go, Dixon was in second place followed Jordan Taylor in the Wayne Taylor Racing DP into the pits but beat him out, taking the lead. The Action Express car was in third. In the last pit stops of the race, Dixon gained even more time, getting a four-second advantage over Taylor. Then a full-course caution came out twenty minutes before the finish when a Prototype Challenge car hit the wall and caught fire, bunching up the field. That closed the pits, but the Wayne Taylor Racing car had to pit during that yellow because of a miscalculation of driver time. No driver can be behind the wheel for more than four hours in a six-hour period but Jordan Taylor was going to go over, so he came in to swap out for brother Ricky. That cost the team any chance of second place, since they took an additional drive-through penalty for entering closed pits. When the track went green again, Sebastien Bourdais in the Action Express car stayed all over Dixon for the final five laps but couldn't get around him.
