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 IDx Nismo and IDx Freeflow concepts are a bridge to the Datsun 510

We're not sure if someone from The Adjustment Bureau stopped by Nissan's PR department to explain the IDx Nismo and IDx Freeflow concepts, but the company's odd press release can't diminish our love for these two show favorites. We had been told to look out for an unnamed Datsun 510 BRE homage, and once we saw the brothers IDx, we knew we'd found them. But the press release doesn't mention anything about the Datsun 510 Brock Racing Enterprises, nor does it mention one Mr. Peter Brock, the man who won two Trans-Am championships in the Seventies for the nascent Japanese budget brand.
Instead, it declares that the cars were the result of a co-creation product development process with "digital natives," said natives being the whippersnappers born after 1990. Nissan says it worked with the young'uns to create two different expressions of "their desire for a basic, authentic configuration for a car." If that's true, it appears that what the kiddies really want are... two different homages to the Datsun 510 BRE that Peter Brock used to win two championships in the seventies for the nascent Japanese brand.
The IDx Freeflow - the "ID" is for "identification," the "x" is "the variable representing the new values and dreams born through communication" - takes the casual approach, with a light khaki exterior hue, a minimalist interior decked out in denim and a console shifter that works a continuously variable transmission. The IDx Nismo is out for blood, from its crimson interior to its five-point harness to its bolt-on flares and sidepipes. We aren't told what the digital natives requested for powerplants, but that's alright; if this is what "co-creation" looks like, we're not entirely against it except where that "CVT" is involved.

Renault keeps 15% stake in Nissan, transfers majority of shares to French trust

Renault and Nissan completed a landmark deal to rebalance their 24-year-long alliance, paving the way for a new relationship after years of acrimony between the two partners. The automakers on Wednesday announced the creation of a French trust to which Renault transferred 28.4% of Nissan shares. The companies first disclosed plans for the trust in January. Renault Group and Nissan now have a cross-shareholding of 15% with lock-up and standstill obligations, the companies and junior alliance partner Mitsubishi Motors Corp. said in a statement. Renault managers in recent weeks have reiterated that staff should no longer share information with their Nissan counterparts, according to people familiar with the situation, after the French carmaker announced in September that aspects of the alliance would be unwound by year-end.  Taken together with the deal to equalize their cross-shareholdings at 15%, the developments are the clearest indications yet that members of one of the world’s biggest automotive tie-ups are increasingly going their separate ways. Renault told employees in September it was moving away from common structures with Nissan in favor of a new, project-by-project approach to working together. The dissolution of the companiesÂ’ joint purchasing organization means the two will no longer pool information on a regular basis due to antitrust concerns. The sell-down of shares held by the trustee will be coordinated with Nissan, which will have the right of first offer to purchase the stock. The trust will have no obligation to sell the shares within a specific or pre-determined period of time. The new alliance deal presented to investors in London in February followed months of tense negotiations that nearly collapsed late last year due to sticking points on intellectual property and disagreement over the valuation of RenaultÂ’s electric-vehicle and software arm Ampere, in which Nissan has agreed to invest. The alliance dates back to 1999, when Renault rescued Nissan with a cash injection and the two formed one of the biggest auto partnerships in the industry. Rivalries and mutual suspicion mounted over the years and came to a head when former leader Carlos Ghosn openly contemplated merging the two companies, contributing to his downfall.
