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 to run two GT-R GT3 cars in 2015 Pirelli World Challenge series

Nissan will be lining up two FIA GT3-spec GT-Rs on the start line of the 2015 Pirelli World Challenge at the Circuit of the Americas March 6-8. Sponsored by Always Evolving, Replay XD cameras, and Nismo, the two entrants will be driven by American GT Academy winner Bryan Heitkotter and Australian racer James Davison. AIM Motorsport, the Canadian race shop founded by Roger Rodas and Erik Davis, will handle preparation of the car. It will be the first time the GT3 GT-R has come to race in America. It will race in a highly varied field, with Audi, Ferrari, Dodge, and Aston Martin among the series runners. Check out the press release below for more details. NISSAN ANNOUNCES PARTNERSHIP WITH ALWAYS EVOLVING TO CAMPAIGN TWO NISSAN GT-R GT3 CARS FOR 2015 PIRELLI WORLD CHALLENGE - 2011 Nissan GT Academy Champion Bryan Heitkotter to pilot #05 GT-R GT3 - IndyCar, Prototype and GT racer James Davison to Campaign #33 GT-R GT3 - First U.S. Appearance of Nissan GT-R Built to FIA GT3 Specifications - Debuts in Pirelli World Challenge at Circuit of the Americas March 6-8 NASHVILLE, Tenn. 19/02/15 – Nissan Motorsports announced today a partnership with Always Evolving (AE) to campaign two GT Academy-NISMO Nissan GT-R GT3 racing cars for the 2015 Pirelli World Challenge season. Nissan GT Academy North America 2011 winner Bryan Heitkotter will drive one of the team cars, while Australian open wheel and GT star James Davison will pilot the second car. Featuring logos from the GT Academy program, the two cars will be co-sponsored by Replay XD and NISMO. AE will utilize AIM Autosport for much of the car preparation and on-track support during the season. Based in Los Angeles, the team was founded in March 2013 by friends Roger Rodas and Erik Davis as a platform combine their passion for cars and their desire to support their favorite charitable organizations. Following Rodas' tragic passing in November 2013, the team has established "Racing in Honor" as their internal mission for the 2014 season in his memory. AIM won the 2012 IMSA GTD team, driver and manufacturer championships, as well as the 2013 manufacturer title while campaigning a Ferrari. "Nissan couldn't be happier to have Always Evolving and AIM as Nissan's partners to campaign the first GT3 spec GT-Rs in the U.S. in Pirelli World Challenge," said Rick Kulach, Nissan North America Motorsports Manager.

Carlos Ghosn changes to hotshot attorney and a new defense strategy

TOKYO — Carlos Ghosn's chief defense attorney Motonari Otsuru resigned and was replaced by a team that includes hotshot lawyer Junichiro Hironaka, in a change of strategy from the ousted Nissan Motor chairman three months after his arrest. Ghosn, Nissan's one-time savior, has been held in detention since his Nov. 19 arrest. He's been indicted and accused of under-reporting his salary and breach of trust. He has denied the charges. The once-feted auto executive hired Hiroshi Kawatsu as head of a new defense team, his office said on Wednesday. Hironaka, 73, has won several high profile cases, helping acquit senior lawmaker Ichiro Ozawa and senior bureaucrat Atsuko Muraki. Hiring Hironaka would mean a more aggressive legal strategy, said Nobuo Gohara, a former prosecutor. Otsuru previously led the special prosecutors' office that is now handling Ghosn's case. "Otsuru was miscast. He worked at the heart of the special prosecutors office so he was not someone who was going to go after them aggressively," Gohara said. "Hironaka is an experienced defense lawyer who has won a number of cases. He will mount a more thorough and aggressive defense." Otsuru's office confirmed his resignation in a statement, but gave no reason for the move. A second member of Ghosn's defense team, Masato Oshikubo, had quit, it said. Go Kondo, Ghosn's third defense lawyer, was unavailable for comment. Ghosn released a short statement thanking Otsuru for his team's "tireless and diligent work," and called him a "very capable and intelligent man and lawyer." The sudden change in attorneys comes ahead of the expected start of informal meetings with prosecutors and judges to discuss pretrial preparations, an indication that there will be no new charges against Ghosn. "As we begin the trial phase, I have decided to engage Hironaka-sensei as my legal counsel," Ghosn said, using an honorific suffix. "I look forward to defending myself vigorously, and this represents the beginning of the process of not only establishing my innocence but also shedding light on the circumstances that led to my unjust detention." Ghosn, 64, told the Nikkei newspaper last month that Nissan executives opposed to his plans for closer ties with automaking partner Renault SA had plotted to remove him. Ghosn was widely credited with rescuing Nissan from near-bankruptcy after he was brought over to Japan in 1999 by Renault after the French automaker bought a chunk of Nissan.
