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 Cruze is lighter, loaded [UPDATE]

UPDATE: Live photos and video of the reveal have been added at the end of the story. Chevrolet revealed the second-generation Cruze Wednesday, promising a larger, more efficient car that drives better than the sedan it replaces. We're particularly excited about the new turbocharged, 1.4-liter four-cylinder engine, which makes 153 horsepower, an upgrade from the outgoing 1.8-liter naturally aspirated engine's 138 hp. Torque climbs even more significantly, from 148 pound-feet to 177 in the new mill. Peak twist can be called up between 2,000 and 4,000 rpm, which should make performance easy to access. Combined with a lighter architecture that slashes the Cruze's curb weight by 250 pounds (although the actual curb weight hasn't been released), the new four-door can hit 60 miles per hour in a respectable eight seconds. That's not hot hatchback territory, but it should be more than suitable for the average consumer. That same consumer should also appreciate the new engine's economy. The Cruze now returns an even 40 miles per gallon on the highway and will cover 530 miles on a single tank, all the while running on plain old 87-octane fuel. There's also a diesel-powered Cruze model, although Chevy didn't release specific details, aside from saying that it will arrive in dealers in 2017, over a year after the gas-powered model's early 2016 on-sale date. Despite the 250-pound drop in weight, the new Cruze has grown significantly. Its wheelbase is now the longest in the segment, with 106.3 inches of sheetmetal between the front and rear axles compared to 105.7 in last year's model, while the sleek new body cuts the coefficient of drag to just 0.29. The overall length increases from 181 inches to 183.7, though the new model is nearly an inch lower overall. That's both good news and bad news for interior space. Rear legroom is up from 35.4 to 36.1, but headroom is down in both the front and backseats by over half an inch. Tech fans, meanwhile, will appreciate the new standard MyLink display. The seven-inch touchscreen is compatible with both Android Auto and Apple CarPlay, while an optional eight-inch display will be offered, as well. 4G LTE wi-fi, heated rear seats, a heated steering wheel, and wireless phone charging will also be offered as an optional extras. New safety features include blind-spot monitoring with cross-traffic alert, lane keeping assist, and forward collision warning.

2023 GM full-size SUVs get Super Cruise expansion pack first

In August, GM announced it had doubled the size of the network of roads available to its Super Cruise hands-free driving feature. Joining the options list in 2017, Super Cruise had been limited to divided interstate highways in the U.S. and Canada. The expansion opened 200,000 miles of additional divided interstate highway as well as major, undivided highways. Both coasts benefit, but there will be a lot more relaxing motoring on the East Coast especially. North of the border, six of the 10 Canadian provinces add enabled roads. Problem is, no GM vehicles have been able to take advantage of the boon. That changes this month, the automaker saying four of its full-size SUVs in specific trims are first in line to make use of the expansion. The SUVs are: 2023 Chevrolet Tahoe Premier and High Country 2023 Chevrolet Suburban Premier and High Country 2023 Cadillac Escalade, Escalade ESV, and Escalade-V 2023 GMC Yukon Denali Ultimate  The vehicles need to have been built on or after October 3, 2022, a production timeline GM says should put the first examples in customer hands this month. The least expensive way to get into Super Cruise is with the two-wheel drive, $77,625 Chevrolet Tahoe Premier with the 3.0-liter inline-six Duramax diesel and the Advanced Technology Package. Vehicles that use the GM's Vehicle Intelligence Platform electrical architecture and already have Super Cruise will receive an over-the-air update "in the coming months" to access the new roads, at no cost to owners. Since other products like the Cadillac CT4 and CT5, Chevrolet Silverado, and GMC Sierra work with the VIP platform as well, they probably aren't far away from the extra capability and they'll bring a lower financial bar to entry.  Related video:
