Motor Trend puts Chevy Camaro Z28 and Porsche 911 GT3 Head 2 Head

Motor Trend admits, "This is an unfair comparison." But that doesn't make it any less fun to watch when they pit a Camaro Z/28 against the Porsche 911 GT3. The former has a 7.0-liter V8 with 505 horsepower and 481 pound-feet of torque shifted through a six-speed manual. The latter has a 3.8-liter flat-six with 475 hp and 324 lb-ft shifted through a seven-speed dual-clutch transmission. Yet those are only the little disparities – the big disparities are mass and money: the Camaro weighs 3,882 pounds and costs $76,150 as-tested, the Porsche weighs 3,267 pounds and costs $145,785. But they're both about hardcore performance, so MT takes them out on the street, to the drag strip, to the parking lot for figure eights and a skidpad test, and finally to Big Willow for Randy Pobst to give his professional assessment. Remember when a lotta people spent a lotta time debating Pirates vs. Ninjas? This is like that, only it's the "haul-ass good-time car" vs. the "track surgeon." Enjoy the debate in the video.

GM applies for LT5, LTX trademarks... are new small block variants coming?

Recently discovered General Motors trademark applications for LT4, LT5, LT88 and LTX have observers wondering what kind of high-performance offerings could be on their way. A new LT4 would mark a return of the engine designation first used on the Corvette Grand Sport, SLP Pontiac Firehawk and SLP Chevrolet Camaro SS from 1996 and 1997. Supposition at Corvette Forum - which provided advance intel on the C7 like these leaked images - believes a new LT4 could go into the high-performance trim of the next-gen, 2015 Camaro that would be more powerful than the 580-horsepower Camaro ZL1.
Seeing an LT5 again would also be déjà vu - in its former life it was a 5.7-liter V8 for the C4 Corvette ZR-1 from 1990-1994 designed by Lotus, producing from 370 hp to 405 hp. A mix of rumor and hope is that the new LT5 will be a supercharged evolution of the 6.2-liter LT1 (pictured) placed in the new C7 Corvette, and that it will go into the C7 version of the ZR1 pumping out something like 700 hp.
The LTX trademark is, as with that last letter, a complete mystery. If the "X" isn't a generic way to denote the whole LT family, it's wondered if it LTX could refer to a crate motor offering like the LSX.

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.
