Nissan GT-R LM Nismo pulls its way to Chi-town

We generally take it as a given that, as far as performance goes, rear-wheel drive is better than front. All-wheel drive can be better than either, in some cases, but you need power going to the wheels that aren't also handling the steering while leaving the others just tagging along for the ride. Right? Well Nissan is here to upend that notion with the new GT-R LM Nismo, presented here at the 2015 Chicago Auto Show. After supporting the DeltaWing project a couple of years ago and fielding its own ZEOD RC prototype last year, Nissan is returning to Le Mans this year with another oddball endurance racer. Only this time, it's going for gold, competing against the likes of Porsche, Audi and Toyota for the overall win in the top-tier LMP1 class. Tying this front-drive, 1,250-horsepower hybrid racing prototype to the all-wheel-drive GT-R may be tenuous, but we have to hand it to Nissan for shaking things up. In the process, Nissan has also confirmed the hot shoes who'll be tasked with manhandling this beast around the Circuit de la Sarthe (and the rest of the tracks on the 2015 FIA WEC calendar). Joining former Le Mans winner and longtime Ferrari test driver Marc Gene will be Super GT champion Tsuigio Matsuda as well as Harry Tincknell and Olivier Pla (both experienced from the largely Nissan-powered LMP2 field), Nissan factory driver Michael Krumm and GT Academy graduates Lucas Ordonez and Jann Mardenborough, both of whom have made their way into professional racing on the merit of their video gaming abilities. We'll be looking forward to watching them try to get the best out of this most innovative Datsun.

Carlos Ghosn was on verge of release — so prosecutors file new allegation

TOKYO — Japanese prosecutors added a new allegation of breach of trust against Nissan's former chairman Carlos Ghosn on Friday, dashing his hopes for posting bail quickly. Ghosn and another former Nissan executive, Greg Kelly, were arrested Nov. 19 and charged with underreporting Ghosn's income by about 5 billion yen ($44 million) in 2011-2015. They also face the prospect of more charges of underreporting Ghosn's income for other years by nearly 10 billion ($80 million) in total. The breach of trust allegations were filed a day after a court rejected prosecutors' request for a longer detention of both men. The new allegation only applies to Ghosn, and Kelly could still be bailed out. A request for bail by Kelly's lawyer is pending court approval, according to the Tokyo District Court, but his release will have to wait until next week since the request was still in process after office hours Friday. Prosecutors in a statement Friday alleged that Ghosn in 2008 transferred a private investment loss worth more than 1.8 billion yen ($16 million) to Nissan by manipulating an unspecified "swap" contract. Ghosn also profited by having the company transfer a total of $14.7 million to another company to benefit himself and that company's owner, who helped in the contract manipulation, prosecutors said. Shin Kukimoto, deputy chief prosecutor at the Tokyo District Prosecutors Office, refuse to say if the two transactions were related or how Ghosn illegally profited. He also declined to identify the collaborator or whether the transactions were made overseas. Ghosn and Kelly are only charged with underreporting Ghosn's pay over five years, in violation of the Financial Instruments and Exchange Act. They have not been formally charged with an additional allegation of underreporting another 4 billion yen ($36 million) for 2016-2018, for which their first 10-day detention was to expire Thursday. Prosecutors have been criticized for separating the allegations as a tactic to detain Ghosn and Kelly longer. They say Ghosn and Kelly are flight risks. The maximum penalty for violating the financial act is up to 10 years in prison, a 10 million yen ($89,000) fine, or both. Breach of trust also carries a similar maximum penalty. The conviction rate in Japan is more than 99 percent for any crime. Ghosn was sent by Renault in 1999 to turn around Nissan, then on the verge of bankruptcy, and he led its rise to become the world's second-largest automaker.

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.
