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.

2014 Toyota Prius crash test rating drops to four stars

If nothing has changed, then how come something changed? That's the question behind the recent drop from five to four stars in the crash test rating for the Toyota Prius. As you can see on the National Highway Traffic Safety Administration (NHTSA) website, the 2014 Prius gets four stars overall while the 2013 got five. The two cars are basically identical, so what gives? Toyota says it is not sure why NHTSA rated the Prius a four this time. Starting with the 2011 model year, NHTSA updated its rating system and says in a FAQ that vehicles that had four- or five-star ratings could get lower ratings "even if no changes have been made to the vehicle." Green Car Reports says that the issue is a new set of frontal barrier tests that were conducted on the 2014 Prius last month and that resulted in the first new bits of crash test data for the car in years. The 2012 and 2013 Prius models were rated based on tests done in February 2011 on a 2011 Prius. All of these are variants of the third-generation model. The next-gen Prius is expected in 2015. Jana Hartline, environmental communication manager at Toyota Motor Sales, USA, told AutoblogGreen that the company doesn't quite know what's going on with the drop in crash test scores: There have been no changes in the test standards and no changes in the car, other than minor reinforcement for small overlap crash test which we believe did not compromise integrity. We are not sure why it rated a 4 this time. We are looking at the test results and we are confident the new generation will move back to 5 stars. 2014 Prius still has a five-star rating for the side crash test and four in the rollover test.

2015 Toyota Auris freshens up in Geneva, prepares for New York debut

Toyota is preparing to bring its Auris hatchback to the US market as a Scion. That makes news of this refreshed Auris, debuting at the 2015 Geneva Motor Show, a fairly noteworthy piece of news. Changes are decidedly light, befitting of a refresh. Toyota has tweaked the headlights, taillights and both bumpers for 2015, featuring a wider grille up front. In the cabin, changes are similarly limited, with updated connectivity equipment, particularly the area around the infotainment system, being the biggest change. A new instrument cluster looks to have been installed, as well. Aside from those changes, though, Toyota didn't do too much to the Auris. You can check out our full gallery of live images for Geneva, and you'll want to be sure to check back here next month, for the official coverage of the Auris-based Scion iM when it debuts at the 2015 New York Auto Show. NEW TOYOTA AURIS TO JOIN NEW AVENSIS ON STAGE AT GENEVA Motor show debut for British-built Auris hatchback and wagon Toyota will reveal its new Auris at the Geneva motor show (3 – 15 March), the British-built hatchback and Touring Sports wagon versions making their debut alongside new Avensis. New Auris enjoys a refreshed design that adds presence and prestige, together with an upgraded cabin and new comfort and safety equipment features. The hybrid remains at the heart of the range, having established itself as the leading powertrain in the line-up, accounting for around half of all Auris sales in Europe in 2014. Nonetheless, the new model heralds the arrival of new and improved petrol and diesel engines, developed with a focus on efficiency and performance. The simultaneous reveal of new Auris and Avensis follows on from last year's introduction of Aygo and Yaris to complete a full rejuvenation of Toyota's core European model range. Both Auris and Avensis will continue to be built side by side at Toyota Manufacturing UK's car plant at Burnaston, near Derby. Toyota will host its Geneva motor show press conference on its stand in Hall 4 at Palexpo, at 12.15pm on 3 March. Related Video:
