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.

Nissan reportedly rejecting Renault proposal for closer ties

TOKYO — Nissan Motor Co Ltd will reject a management integration proposal from French partner Renault SA and will call for an equal capital relationship, the Nikkei newspaper said on Monday, citing sources. Nissan's management feels the Japanese company has not been treated as an equal of Renault under existing capital ties, and a merger would make this inequality permanent, the Nikkei reported. The outlook for the alliance — one of the world's top automaking partnerships — has been in focus since the arrest in November of its main architect, Carlos Ghosn, on charges of financial misconduct. The former Nissan and Renault chairman has denied the charges against him and has said he was the victim of a boardroom coup by Nissan executives opposed to closer ties. To which, Bloomberg reported that it has seen emails in which Nissan executives were working with Japanese government officials to defend the company's independence, as Ghosn was pushing for a full merger. The emails indicate growing concern at high levels of the Japanese government, in the months before Ghosn's arrest, that his merger efforts would boost Renault and its largest shareholder, the French government, and harm Nissan, in a relationship the Japanese already saw as lopsided. The emails indicated a desire to keep the existing structure of the alliance with a "re-balancing of the shareholding" to reduce Renault's 43 percent stake in Nissan, and stated that Nissan's independence "should be respected." Nissan declined to comment directly on the emails, while reiterating that misconduct by Ghosn and his former aide, Greg Kelly, is "the sole cause of the chain of events." Renault saved Nissan from the brink of bankruptcy two decades ago and under their current capital alliance, the French company holds greater control over its much larger partner. Nissan Chief Executive Hiroto Saikawa declined to say whether the company had received a merger proposal from Renault. "Now is not the time to think of such things," he told a group of reporters outside of his house in Tokyo. "At the moment we are focused on improving Nissan's earnings performance. Please give us time to do that." Renault declined to comment on the report. Renault has argued in its proposal that an integration would maximize synergies within the French-Japanese alliance, according to the Nikkei. The Financial Times reported last month of Renault's intention to restart merger talks with Nissan within 12 months.

Evatran, Bosch will sell wireless home charger for as low as $1,998*

At the Consumer Electronics Show in Las Vegas today, the big news for plug in vehicles is that they can now start to ditch the plug. As expected, the system costs around $3,000 and is available for both the Nissan Leaf and the Chevrolet Volt. For the first 250 customers, though, Evatran is offering $1,000 off the standard price, a 30 percent discount. Deliveries start next month and Evatran says it expects the discounted units to all be snatched up in the first half of the year. The wireless charger charges as quickly as conventional corded systems. Called the Plugless Wireless EV charger, the 240-volt station will be installed by Bosch and needs a specific adapter to be used with the Volt or the Leaf (the Leaf version costs $100 more). So, any two-EV families out there will need to pony up double if there's a Chevy and a Nissan in the garage. Of course, since the Plugless system only works with older Leafs (2010-2012 model years - but with any Volt), any late adopters will not be able to take advantage of the new technology, for now. Evatran says the wireless charger "charges the Volt and Leaf as quickly as conventional corded systems and all vehicle features, such as charge-timers and phone applications, can be used seamlessly with the Plugless system." After the first 250 units, standard prices for the wireless chargers take effect again: $2,998 (Volt) and $3,098 (Leaf). Evatran says it will announce wireless chargers for additional vehicles and model years later this year. Evatran and Bosch offer Promotional Pricing as low as $1,998 to first 250 PLUGLESS™ Wireless EV Charging Customers LAS VEGAS, Jan. 6, 2014 /PRNewswire/ -- Evatran Group, Inc. ("Evatran"), in partnership with Bosch Automotive Service Solutions, announced today at the 2014 Consumer Electronics Show that it is offering reduced promotional pricing to the first 250 customers who opt to Go PLUGLESS with their electric vehicle ("EV") experience. The PLUGLESS system offers a convenient, wireless charging alternative to the repetitive process of unplugging and plugging-in electric vehicles. The reduced pricing includes all charging hardware and is as much as a 30% discount off the system's standard MSRP. The discount is available only to the first 250 customers. Initial shipments of the PLUGLESS system, the first wireless EV charging product in the world available to individual EV drivers, will begin in February 2014.
