GM plans new car family for global markets, $5B investment

Globalization remains all the rage in the auto industry, as manufacturers scramble to develop single vehicles that can easily be adapted to the world's disparate market places. Ford has been a champion of this movement, with its One Ford mandate, but now, its cross-town rival is getting in on the action, albeit on a smaller scale. General Motors has announced a $5-billion investment to develop a new Chevrolet-badged family vehicle for global growth markets, including Brazil, Mexico, India, and importantly, China. With the PRC listed as a target market for the new vehicle, it's no surprise that GM is teaming with its Chinese joint-venture partner, SAIC Motor, to develop the vehicle's architecture and engines. The first vehicles should be hitting dealers by 2019, with GM expecting to eventually move some two million units per year. "With a significant majority of anticipated automotive industry growth in 2015 to 2030 outside of mature markets, Chevrolet is taking steps to capitalize on that growth," GM President Dan Ammann said in the attached statement. "Strengthening Chevrolet's position through this major investment is consistent with our global strategy to ensure long-term profitable growth in the markets where we operate." GM is quite focused on developing markets for a new vehicle, going as far as to say that "mature markets" like the US aren't currently being considered for the new family vehicle. As for where it will be built, the press release specifically says it won't be exported to the US, meaning it will very likely be built abroad using parts from local suppliers. Read on for the official press release from General Motors.

GM starting to talk seriously about 200-mile EV

We've been hearing word of a 200-mile EV from Chevrolet for a while now. First, there was General Motors then-CEO Dan Akerson hinting at a $30,000, 200-mile EV that would take the competition by surprise. Then Akerson confirmed that GM is working on a 200-mile EV in a speech in March. LG Chem, which supplies batteries to GM and other automakers, recently said it was working on batteries for EVs with a range of 200 miles. GM's head of global product development Mark Reuss just re-confirmed that there are plans for an EV with a 200-mile range, and sources have told Automotive News what that car will be. While Reuss didn't mention anything about a specific model or platform, two undisclosed sources with knowledge of GM's plans have said that an EV with a range of about 200 miles is indeed in the works, and that it will be based on the Chevrolet Sonic. The sources also gave a timeline for the car, saying it is slated for sometime in 2017. According to Reuss, the plan is for Chevy to offer a lineup of electric cars, with the 200-mile EV joining ranks of the Chevrolet Volt and the Spark EV. He didn't hint at a timeline, but if the sources are correct, we could see a Sonic EV being built within a few years. Reuss sees demand for it, too. When speaking of the Spark EV, currently only available in California and Oregon, he says that "people wish we would sell it all around the country." If he's right about that, it's not difficult to imagine people taking interest in Chevrolet's 200-mile electric car, whether or not it's a Sonic.

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.
