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.

How long will the 'golden age' of performance last?

High-powered sports and luxury cars were everywhere at the New York Auto Show, prompting the obvious question for enthusiasts: How long will this golden age of performance last? Industry leaders have some time before regulations elevate the Corporate Average Fuel Economy level in 2025. Even then, they expect cars rippling with power to survive in some form. "Is it the end of an era," I don't think so," said Ola Kallenius, Daimler AG board member for Mercedes-Benz cars marketing and sales. "That performance element of individual mobility I don't think will ever go away." Kallenius, who oversaw the company's AMG division from 2010-2013, expects it to continue to grow. Last year, AMG sold a record 68,875 units around the world, an increase of 44.6 percent over 2014, with strong growth in the US, China, and Germany. Still, there's always the potential for gas to spike, and pending fuel economy regulations are looming. That could lead AMG to add electrification to its products, Kallenius said, pointing to the electric SLS as a test case. Chevy is also thinking ahead, said Al Oppenheiser, chief engineer of the Camaro. He wouldn't bite when asked about electrification for the Camaro (he did say "never say never"), but admitted in 2025 "it's going to be pretty tough to sell V8s." For now, things are rosy for muscle cars, and Chevy confidently showcased the 640-hp Camaro ZL1 in coupe and convertible form in New York. "I think that this is truly the golden age of performance," Oppenheiser said. It's hard to disagree. News & Analysis News: The 2017 Mazda MX-5 Miata RF was a show-stopper in New York. Analysis: There was a palpable energy when this RF — for Retractable Fastback — was revealed the night before the show at a trendy off-site venue near the Hudson River. Even as a parade of SUVs and flashy luxury cars rolled out the rest of the week, the Miata remained a hot topic. The Retractable Fastback is really a clever targa top, with part of the roof stowing behind the seats, adding about 100 pounds compared to the standard convertible. It makes the car more practical and arguably more attractive. The RF continues Mazda's tradition of selling the Miata with a hardtop variant. The first and second generations offered a detachable one, and a power retractable hardtop (a $1,700 option) was available on third-gen models. Judging by its reception in New York, the RF could prove to be even more popular than its predecessors.

Next-gen Chevy Silverado and GMC Sierra may use carbon fiber

It's been generally accepted that the next generation of full-size GM trucks will use some sort of strong, lightweight material for the beds while retaining steel for the cab. While aluminum seems like the most obvious choice, according to Automotive News, the Chevy Silverado and GMC Sierra will incorporate both aluminum and carbon fiber in their beds. The publication cites sources from within GM, though it seems the introduction of this comparatively exotic material mix is still a few years off. While carbon fiber is both stronger and lighter than steel and aluminum, it takes significantly more time and money to produce, essentially relegating the material to small-volume cars. The main benefit for trucks is the resulting reduction in weight to improve fuel economy without sacrificing the tough, rugged capabilities truck buyers expect. The Ford F-150 made the switch to aluminum for the 2015 model year and it's proved highly successful. It seemed like it was only a matter of time before the competition followed suit. Automotive News says that the next-gen trucks will launch with aluminum beds and that it will take a couple of years before we'll see any carbon fiber incorporated into the design. Even then, only look for the composite material on higher-trim models, with a trickle down to lower-spec trucks possible further in the future. In 2011, GM announced it was working with Japan-based Teijin Limited on a carbon fiber reinforced thermoplastic. There's a good chance that material's introduction will be on trucks.
