2016 Chevrolet Camaro: Notes from the reveal

The 2016 Chevrolet Camaro debuted Saturday evening in Detroit at an enthusiast-oriented event near the city's IndyCar course. While the big news was the Camaro's 200-pound weight loss, tighter chassis, and a snorting new V8, plenty of other morsels of Camaro info came out. Here's some of the more interesting stuff we heard. • The 2.0-liter inline four-cylinder is the first turbocharged engine in a Camaro. • The LT1 borrowed from the Corvette Stingray marks the third time a Camaro has used an engine with that badge. It was previously used in 1970-72 (Z/28), 1993-97 (Z/28), and 1996-97 (SS). • The Camaro was revealed in a tent before nearly 1,000 enthusiasts, General Motors executives (including CEO Mary Barra) and mere feet from the Grand Prix course where IndyCars will run in two weeks. • Chevy hopes to continue to attract new customers with the Camaro and said 63 percent of the fifth-generation buyers were new to the brand. • GM product boss Mark Reuss neatly summed up the Camaro's handling character. "It's wicked fast and extremely nimble." • Reuss on the design goal: make it "look like a car for tomorrow instead of a car from yesterday." • Reuss' first car was a 1967 Camaro, and he's reiterated his passion for the car. "People want to be seen in a Camaro, and that never goes away." • Chevy North America president Alan Batey said he plans to line up a red Camaro as soon as the order bank opens. We assume he'll have early access to that. • Though the appearance is similar, the sixth generation of the Camaro appears a little sleeker and is more aerodynamic thanks to 350 hours in the wind tunnel. Only two parts, the SS badge and the rear bow-tie emblem, are carryover. • Al Oppenheiser, the Camaro's chief engineer, said most of the options (except Magnetic Ride Control, which is SS exclusive), will be offered on the inline four. The engine will be capable of propelling the Camaro to a sprint to 60 miles per hour in well under six seconds. "We don't want to ... make it feel like an excuse car," he said. • Without revealing specifics, Oppenheiser said every Camaro variant will be faster than the model it replaces. •The interior is vastly improved. We got an up-close look in the cabin of one of the cars revealed with a red and white layout, and the materials are much better. The setting is more colorful, and 24 different ambient lighting shades are available. Related Video:

Conquest and controversy conclude the 2014 Rolex 24 at Daytona [spoilers]

If you don't wish to know who won the 2014 Rolex 24 at Daytona, you should avert your eyes right now. We'll even give you a double-space to skedaddle...
For those of you still with us, the first race in the United SportsCar Championship (USCC) is done, but the discussions about it certainly won't end for a while. Daytona Prototypes claimed the first four overall places, the top spot taken by the No. 5 Action Express Coyote-Chevrolet Corvette DP driven by Joao Barbosa, Christian Fittipaldi, Sebastien Bourdain and Burt Friselle. The 16th and final caution of the race bunched the field up for an eight-minute sprint to the flag, so the first place getter finished just 1.4 seconds ahead of the No. 10 Wayne Taylor Racing Dallara-Chevrolet Corvette DP driven by Max Angelelli. Third place went to Brian Friselle in the No. 9 Action Express Chevrolet Corvette DP, 20 seconds down. Chevrolet power hasn't taken the overall win since 2003, eleven years later it scores a one-two-three-four. The No. 6 Muscle Milk/Pickett Racing ORECA-Nissan 03 scored fifth place, the top LMP2 finisher.
The Prototype Challenge class win went to the No. 54 CORE Autosport team of Colin Braun, Jon Bennett, Mark Wilkins and James Gue.

'Killing a Duramax' Gale Banks YouTube series methodically tunes a diesel to death

Learning or perfecting a skill by watching YouTube videos is known as attending YouTube University. GM Authority picked up on one of the video site's more fascinating courses, hosted by Gale Banks; in a fair world, he should be referred to as Professor Banks when it comes to diesel engines and truck tuning. A few months after GM introduced the updated L5P 6.6-liter Duramax diesel V8 in the 2020 Chevrolet Silverado HD and GMC Sierra HD that ships with 454 horsepower and 910 pound-feet of torque, Banks decided he wanted to methodically tune the engine to death. The purpose of the resulting series, called "Killing a Duramax," is to push more power out of the engine in order to discover which parts break and when — or, as Banks puts it, force-feed the Duramax "until the crank hits the street and the heads hit the hood." With that knowledge, Banks can figure out all the weak points on his way to building what he calls a "Superturbo," that being a supercharged, twin-turbo race engine with more than 1,000 hp. What makes the series fascinating is Banks' knowledge, paired with the company's comprehensive iDash engine monitoring system that keeps tabs on a glut of parameters every step of the way. So for instance, you get Banks explaining the differences between inches of mercury and barometric pressure, how those are different from the water content of the air measured in grains, then showing those readouts on the iDash, then explaining in detail how they affect the air density in the Duramax system. The stock Borg-Warner variable turbo gets a lot of airtime — Banks accuses it of being "out to lunch" because he feels it's the weakest link on the engine. That turns into a turbo teardown and a deep explanation of performance pitfalls, such as when air pressure on the turbine begins to diverge from the boost pressure coming from the compressor. Banks says he can keep close tabs on where power's coming from, because the iDash monitors the horsepower contribution provided by the ambient air, the turbo, and the intercooler separately. The major changes so far are a stouter Precision 7675 turbo and TurboSmart wastegate (episode 5), a twin intake (episode 6), a custom liquid-cooled intercooler from a marine engine, a new GM oil cooler and synthetic oil (episode 10), and new injectors (episode 11).
