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.

2016 Chevy SS gets new face, clears throat

Chevy is tweaking the SS once again for the 2016 model year. While the changes might be minor, muscle sedan enthusiasts shouldn't need any more excuse to love the Bowtie brand's performance sedan. The 2016 Chevy SS benefits from revised front-end styling that incorporates new vertical ducts designed to direct airflow over the front wheel wells. It also gets new LED lighting and new functional hood vents to make it look even more aggressive than the current model. Although the 6.2-liter V8 carries over unchanged from the existing version – churning out 415 horsepower and an equal amount of torque – a new dual-mode exhaust promises to be both quieter at lower speeds and angrier-sounding at higher revs. And of course you can still get it with a six-speed manual or automatic transmission. In any event, it should also look the business with its new 19-inch alloys as well. Related Video: 2016 Chevrolet SS Designed for Performance DETROIT – Building on the performance-oriented updates made to the Chevrolet SS last year, the 2016 model features several exterior enhancements that reinforce its presence on the road. A revised front fascia features new, vertical ducts at the outer edges to direct airflow over the front wheel openings to improve aerodynamic efficiency. The fascia also incorporates new LED signature lighting, while new, functional hood vents and new-design 19-inch cast-aluminum wheels contribute to a stronger appearance for the rear-drive sports sedan. "The 2016 SS design changes more fully express the true driving character of the sedan while further enhancing the car's overall performance," said Todd Christensen, Chevrolet Performance Car marketing manager. What hasn't changed is the SS's unique blend of performance, comfort and spaciousness. It features a 6.2L V-8 engine under the hood and turns out an SAE-certified 415 horsepower (310 kW) and 415 lb-ft of torque (563 Nm), and offers a six-speed manual transmission or a paddle-shift six-speed automatic transmission. A new, dual-mode exhaust system for 2016 complements the V-8 engine with quieter performance at low engine speeds and a more muscular engine note at wide-open throttle.

What we know, and think we know, about the 2016 Chevy Volt

With the next-gen Chevy Volt due to make an appearance at the Detroit Auto Show early next year, bits and pieces about the new car are making their way into the press. Perhaps most importantly, the new Volt is going to have better "fuel economy and efficiency," according to GM executive vice president Mark Reuss. The current Volt gets 98 MPGe and 37 miles per gallon on premium fuel. It also has a 38-mile electric-only range. We don't know how GM will improve the efficiency or to what degree, but the logical options include making the car lighter, giving it better aerodynamics and/or improving the powertrain. To that end, one of the big things we don't know for sure includes information on the new gas-powered engine. Forbes says it will be a downsized 1.0-liter, three-cylinder mill instead of the 1.4-liter, four-cylinder used in the current model, which could certainly help the car be more efficient. The new Volt is also going to have more technology, which shouldn't surprise anyone. GM is now openly talking about how it will change the way it markets the Volt, shifting away from the mass-market mentality to focus on the regions where the car is already popular. "There's a Northeast and West Coast market for Volt, and there's nothing wrong with that," Chevy chief marketing officer Tim Mahoney told Forbes. There are rumors that the new Volt will have seating for five by adding a seat in the back. This is something a lot of current Volt owners would love, but we've heard nothing official hinting that this would be the case. We expect the battery to be the new 17.1-kWh version, or maybe even have a capacity increase, so GM would have to seriously repackage the pack to eliminate the ridge that runs from between the front seats and then back to the rear two seats. If you've heard anything official, do let us know.
