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.

Major automakers post mixed US June sales figures

General Motors, Ford and Fiat Chrysler Automobiles NV posted declines in US new vehicle sales for June on Monday, while major Japanese automakers reported stronger figures. Once again, demand for pickup trucks and crossovers offset a decline in sedan sales. Automakers' shares rose as overall industry sales still came in above Wall Street expectations. The US auto industry is bracing for a downturn after hitting a record 17.55 million new vehicles sold in 2016. Analysts had predicted that overall, US vehicle sales would fall in June for the fourth consecutive month. As the market has shown signs of cooling, automakers have hiked discounts and loosened lending terms. Car shopping website Edmunds said on Monday the average length of a car loan reached an all-time high of 69.3 months in June. "It's financially risky, leaving borrowers exposed to being upside down on their vehicles for a large chunk of their loans," said Jessica Caldwell, Edmunds' executive director of industry analysis. GM said its sales fell about 5 percent versus June 2016, but that the industry would see stronger sales in the second half of 2017 versus the first half. "Under the current economic conditions, we anticipate US retail vehicle sales will remain strong for the foreseeable future." GM shares were up 2.4 percent in morning trading, while Ford rose 3.3 percent and FCA shares jumped 6 percent. "US total sales are moderating due to an industry-wide pullback in daily rental sales, but key US economic fundamentals clearly remain positive," said GM chief economist Mustafa Mohatarem. "Under the current economic conditions, we anticipate US retail vehicle sales will remain strong for the foreseeable future." Ford said its sales for June were hit by lower fleet sales to rental agencies, businesses, and government entities, which fell 13.9 percent, while sales to consumers were flat. But it sold a record 406,464 SUVs in the first half of the year, with Explorer sales increasing 23 percent in June. And sales of the F-150 had their strongest June since 2001. On a media call, Ford executives said an initial read of automakers' sales figures indicated a seasonally adjusted annualized rate of around 17 million new vehicles for the month, which would be better than 16.6 million units analysts had predicted. FCA said June sales decreased 7 percent versus the same month a year earlier.

Nissan-Dongfeng JV reveals Venucia VOW concept in Shanghai

Among the dozens of automakers pouring in to the Shanghai Motor Show this week to showcase their latest wares, this one comes from a brand you may never have heard of. It's called Venucia, and it's the product of a joint venture between Nissan and Chinese automaker Dongfeng. Today Venucia has unveiled the VOW Concept, a sporty-looking crossover designed to appeal to young Chinese buyers and previewed in a teaser rendering last week. The design is said to have been inspired by the Salar de Uyuni plateau in the Bolivian Andes, but reminds us a bit of the Lamborghini Urus and Mitsubishi XR-PHEV concepts. And that's no bad thing. Technical details are few and far between, but the name VOW apparently stands for "Venucia Over Wonder," that brand name itself having been derived from the Roman diety Venus. Beyond that we couldn't tell you any more, but even if the VOW concept gets put into production, the chances are slim to none that any version would ever reach a showroom on our side of the pond in the foreseeable future. Venucia debuts VOW Concept at Auto Shanghai 2015 SHANGHAI, China – Venucia, a local brand by Dongfeng Nissan Passenger Vehicle Company (DFL-PV), the passenger vehicle business unit of Nissan's joint venture in China, unveiled the VOW Concept at Auto Shanghai 2015. VOW Concept, a brand new trendy sport crossover concept by Venucia, was developed for the young generations. VOW is the abbreviation of "Venucia Over Wonder," meaning a complete breakthrough in excellence. The forward thinking and bold design is paired with a bright blue body inspired by Bolivia's Salar de Uyuni, a high plateau near the crest of the Andes Mountains with captive fresh and saltwater lakes and the world's largest salt flat. VOW Concept conjures up a new balance of dynamic excellence and elegance. "With the VOW Concept, Venucia is going directly to the young generations and listening to what they have to say about their futures, their hopes and what inspires them. We are determined to bring forward a young and fresh brand that continues to challenge the status quo," said Zhou Xianpeng, DFL-PV deputy managing director. "We believe Venucia will lead future trends as an influencer, and enhance its place in the automotive market in China."
