Nissan's Cummins tie-up bears first fruit with Frontier Diesel Runner concept

The 2014 Chicago Auto Show is proving to be a surprisingly big show for alternative fuels. The Chevrolet Silverado HD pickups are getting a compressed natural gas option and the refreshed BMW X3 is receiving a diesel engine, as is the German automaker's 7 Series. You can add one more oil burner to the mix, at least in concept form: Nissan has released its Frontier Diesel Runner Powered by Cummins with a 2.8-liter, four-cylinder turbodiesel engine and an eight-speed automatic transmission from ZF.
While Nissan calls the Cummins-powered Frontier a concept, it's really just a Frontier DesertRunner 4x2 with a diesel engine replacing the standard 4.0-liter V6, and it's meant to gauge consumer interest for a diesel option in the next-generation Frontier. Nissan has clearly noticed that Chevrolet will be offering a diesel in its new Colorado and wants to see how buyers will react to a mid-size alt-fuel pickup from a Japanese brand.
Exterior modifications to the concept are minor. To show off the engine, there is a transparent hood insert and the pickup has been painted in a two-tone finish of high-gloss red and matte silver edged in carbon fiber trim. The interior gets the same combo of red, silver and carbon fiber to match the outside.

Lebanon has 40 days to figure out what to do with Carlos Ghosn

BEIRUT — Lebanon and Japan have about 40 days to decide whether ousted Nissan boss Carlos Ghosn will be extradited to Japan or stand trial in Lebanon, a judicial source and a source close to Ghosn said on Thursday, following his escape from Japan. Ghosn fled to Lebanon, his childhood home, as he was awaiting trial on charges of under-reporting earnings, breach of trust and misappropriation of company funds, all of which he denies. Japan and Lebanon have no extradition agreement, and Lebanon does not typically hand over its nationals. Ghosn's legal team is hoping to hold the trial in Lebanon, where the former auto executive has deep ties and hopes to clear his name. Japan has in recent days asked Lebanon to clarify what files Tokyo needs to send as part of an official extradition request, the two sources said. "They came back and requested a clarification. Today, we sent that to the Japanese," the judicial source said. That communication is significant because, according to Lebanon's rules for dealing with Interpol notices, it triggers a roughly 40-day period by the end of which agreement must be reached between the countries on where and how Ghosn will stand trial, the sources said. Japan must now either send a formal extradition request to Lebanon or send Ghosn's file to Beirut and agree on a process for trying him there, the source close to Ghosn said. An Interpol spokesperson said on Friday the organization did not itself dictate a timeframe or require any action to be taken by countries and such a framework is set locally. Ghosn, who holds Lebanese, French, and Brazilian nationality, was questioned earlier this month by Lebanese prosecutors who confiscated his passport and imposed a travel ban as part of the Interpol arrest warrant process. The source close to Ghosn said the former executive can appeal to Lebanon's prosecutor to drop the ban and return his passport if Japan does not respond within the timeframe. Japanese prosecutors have said they are still pushing for Ghosn to be tried in Japan. Ghosn has struck out at what he has called Japan's unjust judicial system and said the alternative to fleeing would have been to spend the rest of his life languishing in Tokyo without a fair trial.

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.
