Supercharged 2015 Chevy Corvette Z06 takes the C7 beyond the ZR1

The Z06 is just about everything we got in the last ZR1, but better.
After a bright-yellow false start, here is the real thing: the fourth-generation, 2015 Corvette Z06. If Chevrolet makes a ZR1 version of the C7 Corvette, it's going to be absolutely mega, because the Z06 is just about everything we got in the last ZR1, but better.

Leak reveals GM's 2017 heavy duty diesel trucks to get 910 lb-ft of torque [UPDATE]

UPDATE: Chevrolet officially announced specs for the 2017 Silverado HD and the rumors were true. The truck's new Duramax 6.6-liter turbo-diesel V8 puts out 445 horsepower and 910 pound-feet of torque. Chevrolet says the new motor produces 19 percent more torque and 12 percent more horsepower, while producing 35 percent fewer emissions. Overall, the new engine is a big improvement over the current motor, which generates 397 horsepower and 765 pound-feet of torque. According to Truck Trend, GM's newest heavy duty pickup trucks will pick up quite a bit more power and torque. The publication spotted a recent GM Powertrain ordering catalog that had the engine specs for the 2017 model year and managed to get some screenshots before the catalog was taken down, and they can be viewed here. The screenshots revealed that the 6.6-liter turbodiesel V8 powering the Silverado and Sierra heavy duty models will boast 445 horsepower and 910 lb-ft of torque. This is a substantial gain over the current models' 397 horsepower and 765 lb-ft of torque, and as Truck Trend points out, it exceeds the Ford Super Duty line's horsepower output of 440, but comes short of the 925 lb-ft rating. Truck Trend credits part of this output gain to the new intake system GM will introduce on the 2017 heavy duties. The intake gets 60 percent of its air from a scoop on the hood, with the other 40 percent coming from behind one of the front fenders. GM doesn't reveal horsepower figures in the press release about the scoop, but it does say the cooler air helps with maintaining the engine's output, and that the scoop does produce a ram-air affect, providing more air at speed. As we know, more air plus more fuel equals more power, but there's likely more to the power increase in this engine than only the intake.

Race Recap: 2013 Twelve Hours of Sebring, cakewalk up front, grindfest out back [w/spoilers]

This year's 12 Hours of Sebring wasn't exactly a foregone conclusion because we're still talking about racing, and anything can happen when the speeds are as high as the adrenaline and the desire. But we're still talking about Audi bringing it's two top-spec racers - and its huge budget and its nearly neurotic attention to detail - to a race that it uses as a test bed for The 24 Hours of Le Mans and as a way to open the endurance racing season with a victory.
Besides, 12 hours is a long time, especially at Sebring, and things didn't go all Audi's way. On top of that, although it was a pretty quiet race, behind the Audis things got even grimier, with plenty of battles, plenty of mechanical issues, and the new BMW Z4 GTE and Viper GTS-R being race tested. Oh, and that brand new chromed-out DeltaWing...
