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.

Coronavirus shakes up America's truck market: GM outselling Ford and Ram

FCA, Ford and General Motors joined the rest of the U.S. auto industry in taking heavy volume hits due to coronavirus-related shortages of both cars and customers. The saying goes that a rising tide lifts all boats; it stands to reason, then, that a falling one would have the opposite effect.  However, as we learned Thursday, the automotive market can behave in unpredictable ways. While the F-Series remained the best-selling nameplate in Q1, GM's full-size trucks are now outselling Ford's again for the first time in years, and with this upward thrust from the General, FCA's Ram was unceremoniously booted out of a hard-earned second place.  While late-March sales declines hit just about every major automaker in one way or another, the model-by-model results weren't nearly so uniform. And because the market tends to be a zero-sum game, for every winner, there generally has to be a loser.  In this case, that winner was GM, and its rise had to come at the expense of another automaker, in this case, Ford. F-Series sales dropped 13.1 percent in the first quarter of 2020, while sales of GM's full-sized Silverado and Sierra surged nearly 28% in the same period. FCA's Ram lineup managed a steady-as-she-goes 7% increase. All-in, GM finished the quarter with 197,743 full-size trucks sold to Ford's 186,562. Here's the full breakdown: Ford F-Series: 186,562  Chevrolet Silverado*: 144,734 Ram P/U: 128,805 GMC Sierra: 53,009 *includes 1,036 Medium Duty sales Things are a but murkier in the midsize segment, where the Chevy Colorado slipped 36% to just 21,430 units sold — just a few hundred better than the slow-selling Ford Ranger's Q1 numbers. The GMC Canyon experienced an almost identical slide, finishing the quarter with just 4,483 units sold. For perspective, Jeep sold more than 15,000 Gladiators and Toyota's midsize Tacoma slipped less than 8%, finishing the quarter with nearly 54,000 sales.  We suspect this discrepancy in full- and mid-size truck sales comes from shifting incentives. Ford, GM and FCA would like to keep selling bigger trucks because there's far more profit margin built into their list prices. Even with tens of thousands of dollars in manufacturer money on the hood, big trucks still make money.  Since these automakers report quarterly, we won't get another good look at these numbers until July, but if you thought that 2019 represented the new normal for U.S. auto sales, well, think again.

GM forced to cut truck production amid semiconductor shortage

WASHINGTON — General Motors said Wednesday it will cut some truck production in North America because of the ongoing global semiconductor shortage. The largest U.S. automaker said its Flint Assembly plant that builds the Chevrolet Silverado HD and GMC Sierra HD trucks will operate on one production shift the week of July 26. GM said its Ft. Wayne Assembly plant in Indiana that builds the Chevrolet Silverado 1500 and GMC Sierra 1500 model trucks will be idled next week. GM's Silao Assembly plant in Mexico that also builds the Chevrolet Silverado 1500, Cheyenne (for the Mexico market) and GMC Sierra 1500 will also suspend production next week. All three plants are expected to resume regular production the week of August 2. Related video:
