A Chevy Camaro hybrid? That's what EcoCAR3 could bring

Figuring out a way for a hybrid powertrain to co-exist with the performance expectations of a classic American muscle car is a challenge that could vex that most experienced of automotive engineers. It's a challenge, in fact, being handed to a bunch of college students. Over the next four years, students from 16 North American colleges and universities will attempt to wring fuel efficiency from a 2016 Chevy Camaro as part of EcoCAR3, an advanced-vehicle technology competition sponsored by the Department of Energy, General Motors and others. They'll be attempting to use hybrid or plug-in hybrid technology while not sacrificing the performance of the Camaro, which was selected in part because the current model achieves just 17 miles per gallon in city driving and 28 MPGs on the highway, per EPA numbers. Students will get the latest version of the vehicle to work on, one that is expected to be unveiled next month on Belle Isle in Detroit. "If we still want to produce V8 Camaros, we're going to have to look at alternative methods of propulsion," said Al Oppenheiser, the chief engineer on the Camaro. "So the ideas that these college teams come up with could very easily be adapted to a car like the Camaro." Unlike similar competitions that reward fuel efficiency in vehicles, EcoCAR seeks those gains while emphasizing cost and consumer acceptance of these vehicles. The cars shouldn't look like experiments; they should look like everyday vehicles on the road. Previous competitions have allowed the teams to use whatever powertrain they desired. This time, EcoCAR officials designed the competition to concentrate on hybrid, hybrid-electric and diesel options. Competitors won't have the option of using hydrogen fuel cells as they have in the past. Last year, a team from Colorado State built a vehicle that contained both hydrogen and electric power sources. This year's limit is a curious choice, as some automakers such as Toyota have placed heavy bets on fuel cells in recent years. General Motors also runs a fuel-cell program. With the focus on cost and practicality, however, the program officials wanted to narrow the framework of the contest. "We always have some good decisions on what to make within the scope or out of scope," said Jim Kolhoff, global director of software engineering for General Motors.

Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.

Chevy Silverado Special Ops will go into limited production

Remember the Special Ops edition Silverado? Chevy showcased it as a show truck at SEMA last month. And now it's going into limited production, and proceeds will support the National Navy SEAL Museum. The special pickup was based on a Silverado 1500 in Z71 spec and done up with a special three-tone paint job inspired by the camouflage used on 20th-century warships. Known as Razzle Dazzle, the camo was designed to disguise a ship's form and movements from enemy vessels. Chevy also fitted the show truck with a sport bar, off-road LEDs, lower- and under-body reinforcement, and flared wheel arches packing special 20-inch wheels. Following its debut at SEMA, former GM chairman Dan Akerson (a US Naval Academy alum) and retired Navy SEAL Master Chief Rick Kaiser presented the concept truck at the 116th Army-Navy football game this past weekend. Chevy hasn't said just how many it will build and at what price, but production is slated to be "limited," going on sale in the spring.

Everest Team to raise Post Traumatic Stress Disorder awareness - GM Military Discount expands to include all veterans PHILADELPHIA – For the sixth consecutive year, Chevrolet is the official vehicle sponsor of Saturday's Army-Navy Game. During the game, Chevrolet will honor military service men and women, particularly its special forces. Former General Motors Chairman and CEO Dan Akerson, a U.S. Naval Academy graduate, will join retired U.S. Navy SEAL Master Chief Rick Kaiser, executive director of the National Navy SEAL Museum, to salute the special forces during the presentation of a Chevy Silverado Special Ops Concept vehicle at the game. The limited production version is expected to go on sale next spring. Chevrolet will donate a portion of the proceeds from each Special Operations Silverado sold to benefit the Navy SEAL Museum. "The partnership will also help us aid the families of fallen, injured and active duty Navy SEALs through the efforts of our Trident House and scholarship programs," said Kaiser. Founded in 1985, the museum honors the service and legacy of the U.S. Navy SEALs. Located in Ft. Pierce, Fla., the museum and memorial are recognized as the birthplace of the Navy SEALs.
