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.

Suspects in Ghosn's Japanese escape stand trial in Turkey

ISTANBUL - Seven suspects went on trial in Turkey on Friday over their alleged involvement in former Nissan boss Carlos Ghosn's dramatic escape from Japan to Lebanon via Istanbul at the end of last year. Ghosn, once a titan of the global auto industry, had been arrested in Japan in late 2018 and charged with underreporting his salary and using company funds for personal purposes, charges he denies. The ousted chairman of the alliance of Renault, Nissan Motor Co and Mitsubishi Motors Corp had been awaiting his trial under house arrest in Japan when he made a dramatic escape in December to Beirut, his childhood home. An executive from Turkish private jet operator MNG Jet and four pilots were detained in early January soon after Ghosn's escape and charged with migrant smuggling, a sentence carrying a maximum sentence of eight years in jail. They appeared in white protective overalls, masks and gloves as a measure against the coronavirus, as the court in Istanbul began hearing their defence. Two flight attendants, charged with failing to report a crime - a charge carrying a sentence of up to one year - were also there. The first defendant to speak was a pilot on the Osaka-Istanbul flight, Noyan Pasin, who denied the charge. Prosecutors, in their indictment, had said MNG Jet operations manager Okan Kosemen - who is one of the seven on trial - knew before the Osaka flight that Ghosn would be on board and would transfer to Beirut. Kosemen, who also pleaded not guilty, said in court on Friday he was only told via phone about Ghosn's presence mid-flight from Osaka and cooperated under duress. The prosecution said Kosemen used WhatsApp to communicate with pilots before, during and after the Osaka-Istanbul flight, using terms like "luggage" and "consignment" to refer to Ghosn. The five other suspects also deny the charges, according to the indictment. SAGA SHAKES AUTO WORLD According to the indictment, Kosemen told prosecutors a price of $175,000 was agreed for the flight with a Lebanese broker and paid into MNG Jet's bank account. At the time of the incident, MNG Jet said Kosemen acted without the knowledge of the company and it had filed a criminal complaint for the illegal use of its aircraft. Japan has formally asked the United States to extradite two Americans - a former Green Beret and his son - who also stand accused of helping Ghosn flee Japan. They were arrested in Massachusetts in May.

The Tesla Model S was the best-selling EV of 2015

According to numbers crunched over at Hybrid Cars, the Tesla Model S was the best selling pure electric vehicle last year with 50,366 deliveries. These numbers might not tell the whole story, since Tesla reports deliveries made in 2015 that might have been sold in a different calendar year, while other makers are tallying sales. However, it's inarguable that the Model S ended up in more worldwide driveways than the second-place Nissan Leaf, which did about 43,000 sales. In the US alone, Leaf sales were down 42.8 percent year-on-year, from 30,200 in 2014 to 17,269 last year, and that decline also increased throughout the year. That marks a great finish to a great start to 2015, when Tesla took the lead in EV sales in the US for the first quarter. On top of that, as of last year the Model S becomes the second-best selling EV ever, with 107,148 deliveries since the middle of 2012. It trails the Nissan Leaf, with well over 200,000 worldwide sales. The Chevrolet Volt/Opel Ampera combo takes a close third, with about 106,000 sales. The Nissan and Chevy rivals both launched at the end of 2010, a 16-month head start on the Tesla. Down the charts, the Mitsubishi Outlander PHEV which continues to be forbidden fruit for our market notched 39,000 sales. The BYD Qin PHEV sold 31,898 examples in China, and BYD would take the overall victory from Tesla with 58,728 deliveries if you counted all of its EV and PHEV production, such as its electric buses. The BMW i3 nabbed fourth place with 24,057 global sales. In 2011 the Munich automaker said it wanted to sell 30,000 i3s annually by 2014, but by the time the car launched the company considered 15,000 annual sales 'great for now,' so the 2015 number seems a fine place to wind up.
