General Motors Recalls Nearly 780,000 Cars To Fix Deadly Problem

General Motors is recalling nearly 780,000 compact cars in North America because the engines can shut down unexpectedly and cause crashes. The company says six people have been killed in crashes related to the problem. The recall affects Chevrolet Cobalts and Pontiac G5s from the 2005 through 2007 model years. U.S. safety regulators say the weight of the key ring and rough roads can move the ignition switch out of the run position, cutting the engine and electricity. If that happens, air bags may not work. GM says there have been 22 crashes from the problem. All happened at high speeds. Dealers will replace the ignition switch for free. GM says owners should remove nonessential items from key rings until the problem is fixed.

Chevy Bolt officially keeping name, says marketing boss

There might be just a little confusion at first, but the Bolt name is sticking around. After conducting two consumer studies into the name, Chevrolet isn't worried about the similarity of the monikers for the upcoming EV and existing Volt plug-in hybrid. In fact, the brand thinks the resemblance might be for the best. "The decision is made. The name won't be changed." Chevy head of marketing Tim Mahoney said to The Detroit Free Press. The research shows that the compatibility between the two names actually works quite well. With the Volt well established, people apparently already connect the Bolt to the Bowtie, which is just what a brand wants. Both studies indicated the ""same result, it did well," according to Mahoney. Just a few months ago, the future of the Bolt's name wasn't so clear. GM North America President Alan Batey said the company knew there might be confusion, and it was still mulling its options. The Bolt could be a breakthrough in the EV market with a 200-mile range and a possible price of around $30,000 after incentives. Production is set for the Orion Assembly plant in Michigan following a $200 million upgrade there, and the model could be in dealers as soon as 2017. That's just in time to take on the Tesla Model 3 with its claimed $35,000 price and similar driving distance as the Chevy. Related Video:

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.
