Nissan shows off Le Mans Prototype, says it's world's fastest electric racer [w/video]

Nissan has announced plans and details around its upcoming all-electric racing car, the ZEOD RC. The Zero Emission On Demand Racing car is said to be capable of a top speed in excess of 300 kilometers per hour (186.4 miles per hour), is shaped a bit like the closed-cockpit version of the DeltaWing (albeit, to our eyes, better looking) and will make its debut in 2014 at the 24 Hours of Le Mans. This weekend, visitors to the race will have the opportunity to view the prototype near the Circuit de la Sarthe.
Nissan's ZEOD RC has been invited by Le Mans organizers to compete as the Garage 56 entry in next year's race; that's essentially a spot on the grid held for vehicles with new and/or cutting edge technology.
Short of announcing a partnership with Michelin to develop tires for the EV racecar, however, Nissan is mum on any kind of battery or motor specification for the ZEOD. The press release (below) offers a sense that the Nissan and Nismo teams have still got a lot of work to do before the 2014 race. Ben Bowlby, designer of the ZEOD RC, says "We have many options to consider and test. The test program is part of a longer term goal of developing a system and a set of rules for this type of technology in partnership with the ACO that would be best suited to competing at the highest level of this sport."

Nissan Juke Nismo RSnow is dashing through the snow

With much of the Northeastern US buried and shoveling out from under a think blanket of snow, the possibility of getting stuck is a concern for some drivers. However, Nissan is ready for the absolute worst winter can throw at it with the new Juke Nismo RSnow. This wild-looking off-roader is a nearly stock Juke Nismo RS with all-wheel drive and the Xtronic CVT. Of course, there are some very obvious changes – tracks replace all four wheels. According to Nissan spokesperson Josh Clifton to Autoblog, the Dominator Track Systems come from a company called American Track Truck. The only other alterations are tweaks to the fascias to fit the parts and reprogramming for the torque-vectoring all-wheel-drive system. The top speed is estimated at around 62 miles per hour. "It was built as a support vehicle for an ice-driving event in Lapland, Finland," said Clifton to Autoblog via email. The automaker is releasing more info about the RSnow soon, but in the meantime watch the brief clip of this all-weather Juke blasting through some powder, below.

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.
