Nissan VP suggests next Z will offer multiple engines

Roel de Vries, the corporate vice president and global head of marketing and brand strategy for Nissan, told Australia's CarAdvice that as far as he's concerned, any engine in the 370Z "[needs] to deliver on what the car stands for and if the 370Z stands for real performance and real driving I think it doesn't need a V6 to do that." At first read, it could look like de Vries is softening us up for a next-generation Z that doesn't come with a V6, a move that would disappoint a lot of the coupe's fans. Or, what if de Vries was actually getting us ready for a Z with multiple engine options, instead of only a V6, in order to expand its global appeal? That appeared to be the gist of his comments, the exec saying that they couldn't sell a V6-engined Z in Europe, but even if they offer a four-cylinder there, the V6 could live on because, "why should we give it up?" With the coupe's current name a factor of the 3.7-liter displacement of it's V6, though, what is the future for a car with several engine options? Said de Vries, "We [will] definitely keep the Z name, but when we did 350 to 370 it was because of the capacity, but who says the next-generation doesn't have three engines and its not just called Z?" This kind of talk has been going on all year, the real question being how many engines will the car get and what's the endgame. At the beginning of the year, ex product chief Andy Palmer said the car codenamed Z35 would use a "downsized four-cylinder turbocharged engine." In August, Motor Trend reported that the next Z would offer "a mixture of smaller but powerful engines," including a hybrid, but that a V6 would remain the headliner. Two weeks later, MT said that Nissan wanted to transition customers from the naturally aspirated V6 to a turbocharged four-cylinder with the same power, eventually, but would begin with both on the menu. Parallel to that are Shiro Nakamura's out-loud musings about how to merge the next Z and the IDx concepts into "a more affordable, more approachable sports car." The answers, whatever they are, will be a big deal for the brand.

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.

Recharge Wrap-up: Renault EV movie, H2 fueling in Paris

Renault has debuted a new documentary called Le Peuple Electrique, or The Electric People. The film features two drivers touring France over the course of three weeks in a Renault Zoe electric vehicle. Along the way, the duo meet and come to rely upon other members of the EV driving community. Renault is showcasing the film at the COP21 summit in Paris to give an insight into the culture of electric vehicles. See the film above (it's in French), and read more in the press release from Renault.Nissan and Renault have joined forces for an ad campaign for their electric vehicles. The campaign, which focuses on the Nissan Leaf and Renault Zoe, coincides with the COP21 environmental summit, for which the automakers have supplied 200 electric cars as shuttles for attendees. The ad campaign consists of press, posters, and a series of six videos, each 15 seconds in length, to be shown on social media networks in France, the UK, Germany, Spain and Italy.

Electric taxi company STEP plans to launch a fleet of at least 70 Hyundai ix35 (Tucson) Fuel Cell taxis in the next five years. The fueling station will be located at Cours Albert 1er near the Eiffel Tower, so this is truly in the heart of the city. "This first station will allow us to promote the benefits of hydrogen as a clean energy for vehicles with consumers," says Air Liquide's Francois Darchis. "Hydrogen offers a concrete solution to the challenges posed by the issue of sustainable mobility, reducing greenhouse gas emissions as well as local pollution in urban areas."
