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.

2022 Chevy Silverado ZR2 vs Ford F-150 Raptor and Ram 1500 TRX Spec Comparison

The 2022 Chevy Silverado refresh brings a new top dog off-road Chevy, the Silverado ZR2. It has the biggest V8 available, flashy looks, trick suspension and other off-road goodies. And naturally, that means people will be comparing it with the other top-rung off-road trucks, the Ford F-150 Raptor and the Ram 1500 TRX. As such, we've assembled the specifications available so far to see how the three super trucks compare. Having just been revealed, there are a few things we don't know about the ZR2, such as fuel economy and some other suspension details, but we know quite a lot. And from what we know, the ZR2 has some interesting positives and negatives compared to the other trucks. First, it's pretty clear that the ZR2 isn't as extreme as the Raptor and TRX. We wouldn't be surprised if Chevrolet insists they aren't direct competitors. Specifically it has the least power and torque by a fair margin, the smallest tires and the least ground clearance. Still, it's not completely fighting with an arm tied behind its back. It's the narrowest by a significant margin, which is good for tighter trails. It also has the best towing and payload capacity, and the approach, break-over and departure angles are quite competitive despite the "little" tires. It's also the only one to boast a locking front differential in addition to a rear locker. The Raptor can be had with a limited-slip front differential, and the TRX only gets an open front differential. Check out all the specific numbers in the chart below, as well as additional stories on the trucks featured below.

GM to cut production at 5 plants in North America, kill several models

DETROIT/WASHINGTON — General Motors Co said on Monday it will cut production of slow-selling models and slash its North American workforce in the face of a stagnant market for traditional gas-powered sedans, shifting more investment to electric and autonomous vehicles. The announcement is the biggest restructuring in North America for the U.S. No. 1 carmaker since its bankruptcy a decade ago. GM said it will take pre-tax charges of $3 billion to $3.8 billion to pay for the cutbacks, but expects the actions to improve annual free cash flow by $6 billion by the end of 2020. GM plans to halt production next year at three assembly plants: Lordstown, Ohio, Hamtramck, Michigan, and Oshawa, Ontario. The company also plans to stop building several models now assembled at those plants, including the Chevrolet Cruze, the Cadillac CT6 and the Buick LaCrosse, the sources said. Sources said the Chevrolet Volt, Impala and Cadillac XTS would also be discontinued. Signs of the demise of six passenger-car models have been swirling since July. Plants in Baltimore, Maryland, and Warren, Michigan, that assemble powertrain components have no products assigned to them after 2019 and thus are at risk of closure, the company said. It will also close two factories outside North America, but did not identify those plants. The AP reported that 14,700 jobs would be affected. Some 8,100 of those would be white-collar jobs reduced through buyouts or layoffs. The No. 1 U.S. automaker signaled the latest belt-tightening in late October when it offered buyouts to 50,000 salaried employees in North America. The company also said it will cut executive ranks by 25 per cent to "streamline decision making." Some 6,000 factory workers could lose their jobs or be transferred to other plants. Its shares were last up 6.2 percent at $38.16. Tariff 'headwinds' and cost-cutting GM Chief Executive Officer Mary Barra told reporters on Monday the company can reduce annual capital spending by $1.5 billion and increase investment in electric and autonomous vehicles and connected vehicle technology because it has largely completed investing in new generations of trucks and sport utility vehicles. Some 75 percent of its global sales will come from just five vehicle architectures by early in the 2020s. It plans to reduce annual capital spending to $7 billion by 2020 from an average of $8.5 billion a year during the 2017-2019 period.
