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: Volvo buys Polestar, makes performance a priority

Volvo is taking its performance business in-house, and the Swedish carmaker announced Tuesday that it bought tuning company Polestar, which has long been known for producing sporty Volvos. The move allows Volvo to ramp up its performance business, and it plans to increase Polestar-branded vehicle sales to 1,000 to 1,500 annually, up from the 750 total projected for this year. The companies have been working together on motorsports projects since 1996. Financial terms of the sale were not released, and Polestar workers will move over to Volvo. Former Polestar owner Christian Dahl will keep control of the Polestar racing team and operate it under a new name. In addition to sales volume, Volvo has ambitious plans for other parts of Polestar, including its aftermarket business. Volvo also said it will use its twin-engine hybrid technology for Polestar models in the future, though specifics and timing were not revealed. Meanwhile, Volvo announced it will offer a run of 265 total Polestars in the United States for the 2016 model year, with S60 and V60s available. "Driving a Volvo Polestar is a special experience. We have decided to bring this experience to more Volvo drivers, placing the full resources of Volvo behind the development of Polestar as the model name for our high performance cars," Volvo CEO Hakan Samuelsson said in a statement. OTHER NEWS & NOTES 2016 Chevy Silverado, GMC Sierra, get nose jobs Automakers tend to refer to light updates as 'facelifts,' and that's exactly what Chevy gave the 2016 Silverado and GMC Sierra. Chevy slightly changed the front end of the truck. Using the one photo released of the new Z71 model as a guide, we can see that the headlights went from a stacked vertical design to single bulbs, and they are set on top of LED running lights. The grille has more body-colored elements instead of shiny metal, and the hood has a new line running down the middle (look really closely). The design theme will be similar across the portfolio, though materials and details will vary, a spokesman said. Some models, like the High Country and LTZ will have more chrome, and the LEDs are only for the upper trims. Chevy also said it will use the eight-speed automatic transmission on more versions of the Silverado, and it updated the MyLink feature to support Android Auto and Apple CarPlay.
