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.

The Corvette Museum sinkhole has been filled

After swallowing eight of the most prized pieces of the collection from the National Corvette Museum, the massive sinkhole from a year ago is rapidly becoming nothing but a bad memory. Based on the museum's weekly construction update, you can barely see the remnants of the 25-foot deep hole once in the floor. The Corvette Museum's Skydome was not always going to look like this. The original hope was to keep the sinkhole there as a tourist attraction. That plan eventually fell through, though, and instead it was decided five of the less-damaged Corvettes would remain unrestored. Progress has been moving fast to get the repairs done. Even a month ago, the hole was still very visible, and the construction company used remote-controlled Bobcat loaders to fill it in. Now, the museum has launched a contest to guess how many tons of stone it took to fill in the massive crater. The winner gets a print of the 2009 Corvette ZR1 Blue Devil being lifted out.

Weekly Recap: Racing legend Jim Hall explains Chevy's futuristic Chaparral concept

"I said our cars are built to be winners." – Jim Hall Racing legend Jim Hall never thought he'd be a video game consultant, but when Chevrolet asked for his advice to create a futuristic Chaparral for the Vision Gran Turismo series, he was eager to help. He reviewed early sketches and suggested some changes that made it onto the concept, including the addition of a camera that's mounted onto a mast over the cabin to aid the driver. The Chevy Chaparral 2X Vision Gran Turismo concept was revealed this week at the Los Angeles Auto Show and will be part of a downloadable update for PlayStation 3's Gran Turismo 6 in December. Theoretically, at least, it uses a laser-beam propulsion system and an air-powered generator to produce 900 horsepower in the video game. It's capable of sprinting to 60 miles per hour in 1.5 seconds en route to a top speed of 240 mph. Those gaudy performance specs – even in the virtual world – came at Hall's urging. "I said our cars are built to be winners," Hall told Autoblog on the floor of the Los Angeles show. The 79-year-old drove Lotus racecars in Formula One before launching the successful Chaparral Cars in the 1960s. Like his innovative Can-Am racers, the Vision Gran Turismo project has an eye toward the future. It also introduces the iconic Chaparral name to a new generation of fans, and hopefully, Hall says, gets them excited about engineering and design. "It emulates what we did in the '60s," he said. And what they did back then still resonates. Chaparral Racing and Chevy partnered more than 45 years ago for development work on the composite monocoque chassis, lightweight alloy powertrains, automatic gearboxes and active aerodynamics. "He [Hall] walked right back into this and was able to apply thinkings and learnings," said Clay Dean, General Motors executive director of advanced design. The Chevy Chaparral 2X Vision Gran Turismo concept was created at GM's North Hollywood advanced design studio, and it will be on display at the show through November.
