Nissan Leaf sets another monthly sales record, Chevy Volt remains steady

Here we go again. Another month in the books and another month of record sales by the Nissan Leaf in the US. For October, the world's best-selling pure EV sold 2,589 units, which is 29.3 percent more than October 2013. That makes it 20 times in a row that Nissan can say that last month sales were better than the same month a year before. All told, Nissan has sold 24,411 Leafs in the US this year, a new record, reflecting an overall Leaf sales rate that is up 35 percent, year-to-date. Nissan isn't stopping, either. A new TV ad, one that, "encourages consumers to kick gas" by saving money on fuel will start airing today in major markets, according to Toby Perry, director of Nissan's EV marketing. You can watch it below. As for the Chevy Volt, things remained steady last month in the face of a new model that's coming in the second half of 2015. Chevy sold 1,439 Volts last month, which is about the same as September (1,394) but down 28.8 percent from the October 2013 despite GM having its best overall US October sales this year since 2007. So far, 2014 Volt year-to-date sales are down 14.9 percent through the end of October compared to 2013. And that wraps up the flash report on monthly sales for these two long-standing plug-in vehicles in the US market. As always, we'll have our in-depth write-up of US green car sales available soon.

Nissan teases Sao Paolo CUV concept, production future likely

Back in 2012 at Brazil's São Paulo Motor Show, Nissan showed off an angular subcompact crossover concept, Extrem, that seemed to to portend the future of the Nissan Juke. Now, the Japanese automaker is teasing an as-yet-unnamed CUV concept for this year's show. The new showcar, set for an October 28 unveiling, is expected to be a closer-to-production version of the Extrem ethos.
Why should we care? Autoblog has reason to believe that this vehicle is under consideration for global distribution. The production Extrem - or whatever it ends up being called - is likely to be positioned size-wise in between the Juke and the recently upsized Rogue, offering more space and still-adventuresome styling, yet at a less expensive price. If accurate, that sounds like the production model will be a fair bit larger than the conceptual Xtrem, which was built atop a modified version of Nissan's V-platform, a model that underpins its March supermini (and speaking of the March, Nissan has also teased what looks to be a sporty concept version of it for the Brazilian show, too).
It's important to note that Nissan already has a bustling small CUV portfolio globally, what with its popular Qashqai / X-Trail models in markets beyond ours. There continues to be persistent rumors that Nissan is considering bringing over the Qashqai, as well, a model seemingly already quite close in size and execution to the Rogue. Despite this, Nissan has shown no hesitation in exploring every niche of the burgeoning CUV market, and while not every derivative has been a success, models like the Juke have rewarded the company's bravery with handsome sales.

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.
