Next-gen Chevy Camaro ZL1 teases big changes under its camo

With work complete on the lighter, stiffer 2016 Camaro, it's time for Chevrolet's engineers to really start having fun by developing the next, ZL1 version. Here it is for the first time. Unfortunately, the muscle car is still wearing quite a bit of camouflage, but the concealment isn't enough to hide some of the meaner model's more obvious performance tweaks. Starting from the front, this Camaro now wears a much more aggressive front fascia with bigger air inlets. Managing the airflow around the engine bay is clearly a big deal because another photo reveals a fairly large extractor in the hood, as well. Moving down the profile, the lower side sills and orientation of the camo suggest some blistered fenders in the back to cover wider rubber, and at the very rear a much larger wing further suggests the need to keep things planted to the road. Check out the comparison images in the gallery for a better look at the tweaks. What will power the next ZL1 is still entirely a mystery, although sticking with a supercharged 6.2-liter V8 could be a possibility, especially if you take the big extractor in the hood as a hint. Whereas the current ZL1 makes 580 horsepower and 556 pound-feet of torque, the LT4 in the latest Cadillac CTS-V pumps out 640 hp and 630 lb-ft. Combined with the Camaro's other improvements, we're thinking that this new ZL1 will be quite a hot ticket, and based on these spy shots, we can't wait to find out.

Callaway, Lingenfelter boost Corvette Z06 way beyond 700 hp

With 650 horsepower and just as much torque on tap, few would accuse the latest Corvette Z06 of being down on power. But for those who'll always demand more, two leading Corvette tuners have just announced new tuning packages for the Z06 to boost Chevy's flagship well beyond 700 horsepower. The more powerful of the two comes from Callaway Cars, which has added a larger supercharger, a triple-action intercooler, and more to increase output to a massive 757 horsepower and 777 pound-feet of torque. The result, according to Callaway, is a 0-60 time quoted at 2.8 seconds and a quarter-mile run in 10.5. The package also includes a reshaped hood, all manner of trim upgrades, and a three-year warranty, and will set you back nearly $17k on top of the cost of donor vehicle that currently lists for $79,000. In what could only come second relative to Callaway's kit, Lingenfelter Performance Engineering has also released a Stage 1 package for the Z06. The kit includes a new dry sump damper, upgraded supercharger pulley and drive belt, and more – all of which Lingenfelter says will boost the Vette's output up to 720 hp and 730 lb-ft. Revised performance figures weren't released, but despite the 37-horse, 47 lb-ft deficit, we doubt it'd trail Callaway's by much. But both would likely leave the stock Z06 in their dust, and you can read more about them in the press releases below.

Equipped with Callaway's GenThree Supercharger, the Corvette Z06 now produces 757 bhp @ 6,200 rpm and 777 lb-ft @ 4,500 rpm (SAE). A launch to 60 mph is now achieved in 2.8 seconds, and a quarter-mile in 10.5 seconds at 131 mph. Why Go Big, When You Can Go Bigger? - Size Matters. To reach that power (which is up from 650 bhp / 650 lb-ft) the supercharger itself needed to be bigger since the output of a positive displacement supercharger is proportionate to its size. The Callaway GenThree supercharger is 32% larger in displacement (2300cc vs 1740cc). Cooling - Callaway engineers recognize that a key contributor to maximizing power is reduction of inlet air temperature associated with forced induction.

Chevy confirms Corvette Stingray Convertible for Geneva

Want proof that General Motors has increased global ambitions for its 2014 Chevrolet Corvette Stingray? It's staging the world premiere of the model's convertible variant at the Geneva Motor Show early next month.
As previously rumored, the droptop rendered above will debut at the Swiss show, making its first appearance anywhere on March 5. According to Susan Docherty, president and managing director of Chevrolet, the location makes sense because Corvette "...is an icon that has long been recognized and admired even in countries where it's never officially been offered."
While neither Chevrolet nor the Corvette has a major sales presence in Switzerland, the Bowtie's European headquarters is located in Zurich (about three hours to the northeast of Geneva) and GM has made it clear that it wants to build the Chevrolet brand up across Europe.
