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.

Kayaba, Sumitomo to pay millions for price-fixing in US

Kayaba Industry Co, which does business in the US as suspension parts maker KYB, and Sumitomo Electric Industries are facing payments in the millions to settle price-fixing cases about the components that they make. As part of the Department of Justice's ongoing crackdown of price fixing in the auto industry, KYB agreed to pay $62 million and pleaded guilty to conspiracy to set the cost of shock absorbers from the mid '90s through 2012. The company allegedly worked with co-conspirators to keep the cost of the parts high, and those components then made it into vehicles from Honda, Kawasaki, Nissan, Subaru, Suzuki, and Toyota. "Any collusive agreement among competitors to restrict price competition undercuts our free enterprise system and violates the law," said Carter M. Stewart, US Attorney of the Southern District of Ohio, in the DoJ's announcement. Over the past few years, the DoJ has brought cases against 37 parts suppliers and 55 executives, leading to over $2.6 billion in fines. The investigations haven't always been so successful – some of the Japanese execs fled from the US to avoid prosecution. Critics allege that price fixing is simply how business is done. According to Automotive News, Sumitomo Electric Industries is also facing a $50 million settlement in a civil lawsuit that's related to price fixing of parts like wiring harnesses and heater control panels. The plaintiffs include owners and dealers that purchased vehicles with these parts. The company asserts that the violations are from before 2010, and it now has different process in place to avoid further violations. KYB Agrees to Plead Guilty and Pay $62 Million Criminal Fine for Fixing Price of Shock Absorbers Kayaba Industry Co. Ltd., dba KYB Corporation (KYB) has agreed to plead guilty and to pay a $62 million criminal fine for its role in a conspiracy to fix the price of shock absorbers installed in cars and motorcycles sold to U.S. consumers. According to charges filed today, KYB conspired from the mid-1990s until 2012 to fix the prices of shock absorbers sold to Fuji Heavy Industries Ltd. (manufacturer of Subaru vehicles), Honda Motor Co. Ltd., Kawasaki Heavy Industries Ltd., Nissan Motor Company Ltd., Suzuki Motor Corporation and Toyota Motor Company, including their subsidiaries in the United States.

Nissan Sentra gets mean with 240-hp Nismo concept

Nissan's Sentra Nismo Concept made its world debut at the LA Auto Show today as part of the Japanese automaker's intitiative to expand its performance line of factory performance models, and it's packing a turbocharged inline four-cylinder engine with 240 horsepower and 240 pound-feet of torque - that's 110 hp more than the regular Sentra.
Of course, no high-performance version of any car would be complete without the suspension upgrades to handle the power, and Nissan has fitted Nismo-tuned suspension and a limited-slip differential to the little front-wheel-drive sedan. With such an increase in power, Nissan wisely chose to swap out the stock brakes for the Brembo calipers and discs from the 370Z. Larger 225-millimeter-wide tires are wrapped around 19-inch Rays wheels and contained within wider fender flares. The steering and six-speed manual transmission also were tuned by Nismo.
The exterior gets new aerodynamic bits, such as a revised front fascia, a chin spoiler and a new rear spoiler, while the interior gets a nice set of Recaro seats and a leather-and-Alcantara steering wheel.
