Before next-gen arrives, Nissan Leaf may get 120-mile battery

As Nissan prepares to unveil its next-generation Leaf electric vehicle, the Japanese automaker may come out with an "interim" version of sorts that could spur lagging sales of the model in the US. So says Automotive News, which reports from a person familiar with the process who wasn't identified that Nissan soon may start selling a Leaf with a 30-kilowatt-hour battery, up from the current 24 kWh version. It could arrive as soon as next month. Indeed, Nissan's temporary solution may be to provide range-hungry drivers with a single-charge range of 100 to 120 miles. Sure, that doesn't quite match up with the distance a gas-powered vehicle can go on a full tank, but it would be an notable upgrade from the current single-charge range of 84 miles for the Leaf. Word first got out about the Leaf possibly adding a 30-kWh battery in late May. Nissan's contending with falling Leaf sales in the US that may be caused by both the expiration of some plug-in vehicle credits as well as the prospect of a glut of used Leafs back on the market as three-year leases run out. Through the first half of the year, Nissan sold 9,816 Leaf vehicles in the US, a 23-percent drop from a year ago. Nissan CEO Carlos Ghosn said in a June 23 shareholders meeting that the company can improve battery technology enough to put an electric vehicle's single-charge range on par with the distance a conventional car can go on a full tank of gas.

Nissan Qashai gets the Juke R treatment

It would appear that we're a little behind the times on this one, but a UK-based tuner of the Nissan GT-R is creating its own take on the lustworthy Juke-R starting with the Nissan Qashqai crossover. Severnvalley Motorsport claims to be the leading authority for tuning of the current GT-R in Europe. The outfit is now turning its attention to stuffing the drivetrain of a GT-R under the body of a Qashqai+2 - a seven-passenger compact crossover similar in size to our Nissan Rogue - resulting in the Qashqai-R.
The project started back in March when Severnvalley took delivery of a new Qashqai. After stripping the crossover down to its bare essentials and building a custom jig to support the body shell, it was then transferred onto an awaiting GT-R chassis. The crew aimed to keep Qashqai's appearance as stock as possible, but fender extensions and hood vents were required to accommodate the sports car underpinnings.
The white Qashqai-R seen above will be tuned to produce 900 horsepower, while a black version will get bumped up to 1,000 hp. And, looking at the build photos, we surmise that this project will take nothing less than a herculean feat of supercar determination before it's through.

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.
