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.

Refreshed 2014 Camaro confirmed for New York debut

We've already seen leaked specs and potential spy shots, but the refreshed 2014 Chevrolet Camaro will make its official debut at the New York Auto Show in a few weeks.
Besides a tweaked exterior and the possibility of a high-output LS7 under the hood, we really don't know much else about the 2014 Camaro, but here's hoping for an improved interior, too.
In addition to the refreshed Camaro, Chevrolet will also be showing off the recently introduced Chevrolet SS, making its debut on the auto show circuit, and we'll also get our first look at the C7 Corvette coupe and convertible side-by-side.

GM and Ford quarterly sales continue to slump in China

BEIJING — General Motors and Ford announced their quarterly sales in China fell, albeit at a slower pace sequentially, as the U.S. automakers were hit by a slowing economy amid the Sino-U.S. trade war. GM's vehicle sales in China for the quarter ended June 30 dropped 12.2%, while Ford's sales slumped by 21.7%. While GM also suffered from heightened competition in its key mid-priced SUV segment, Ford was hurt by the limited new models for customers to choose from. For the first quarter of this year, Ford's sales in China tumbled 35.8 percent while GM's skid 17.5 percent. Still, the numbers from GM, the second biggest international automaker in China by sales, and Ford portend more uncertainty for the industry which is trying to rebound from a downward spiral that led to its first annual sales decline last year in more than two decades. GM delivered 1.57 million vehicles in China in the January-June period this year, while Ford delivered 290,321 vehicles. China's factory activity shrank more than expected in June, highlighting the need for more economic stimulus amid higher U.S. tariffs and weaker domestic demand. Annual car sales in China fell last year for the first time since the 1990s, and they are expected to fall this year too. Sales tumbled 16.4% in May from the same month a year prior, the China Association of Automobile Manufacturers (CAAM) said. That marked the 11th consecutive month of decline and followed falls of 14.6% in April and 5.2% in March. U.S. car companies' share of total China passenger vehicles sales fell to 9.6% in the first five months of this year from 10.9% in the year-ago period, according to CAAM. Over the same period, German car makers' share has risen to 23.3% from 20.9% and Japanese auto makers' to 21.3% from 17.3%. CAAM is set to announce June sales next week, which industry analysts forecast will be negative.   New models In China, GM has a joint venture with SAIC Motor Corp, in which the Buick, Chevrolet and Cadillac are made. It also has another venture, with SAIC and GuangxiAutomobile Group, in which they make no-frills minivans and have started to make higher-end cars. Sales of GM's affordable brand Baojun dropped 31.8% for the latest quarter. But luxury brand Cadillac's sales jumped 36.6%. GM sold 3.64 million units in China last year, down from 4.04 units in 2017. Ford makes cars in China through its joint venture with Chongqing Changan Automobile Co and Jiangling Motors Corp (JMC).
