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.

2015 Nissan Versa Note adds sporty-ish SR trim

The funny, little Nissan Versa Note is getting a new trim level - two, actually - for the 2015 model year. And the one you see above is the sporty-ish Note SR, making its debut at the Chicago Auto Show this week.
Underneath, it's the same Versa Note we've already driven, complete with Nissan's 109-horsepower, 1.6-liter inline four-cylinder engine and up to 40 miles per gallon highway. The SR's changes are purely cosmetic, with a revised front fascia featuring smoked headlamps, standard foglamps and black chrome accents. Those are matched with new dark-finished 16-inch alloy wheels, revised mirrors and side sills, along with a new rear roof spoiler.
A few interior enhancements have been made, as well, with the addition of a "370Z-inspired" leather-wrapped steering wheel, suede-like fabric on the seats with orange accents and a piano-black center stack.

Nissan Sway displays the future of the compact hatch [w/videos]

Nissan is giving a glimpse at its future compact hatchback design with the Sway Concept at the 2015 Geneva Motor Show. The little, egg-shaped hatchback cribs styling elements from earlier show cars from the brand and mixes them together into an attractive five-door. Though, the company makes no mention of the model's powertrain. The Sway's most eye-arresting feature is its arching hood that leads to a deep, V-shaped grille similar to the Lannia Concept. The design element is flanked on both sides by boomerang-shaped LED headlights, and there's a splash of color from the orange accents under the air intakes. To draw the eye from front to rear, a crease flows over the fenders and then sweeps all the way back to the taillights. Nissan's floating roof motif also makes an appearance here, although it's not quite as obvious as on larger vehicles. As is common on show cars, the Sway has suicide doors with no B-pillar to let attendees in Switzerland have a good look inside. The interior appears to be an airy place to take a drive with a panoramic glass roof, and a windshield that rises up over the front occupants' heads. The driver gets a simple instrument cluster that's dominated by just two gauges, but there's a tablet at the center of the dashboard to provide extra info. According to Nissan, the whole point of the Sway's design is to take compact hatchback styling in a bolder direction. The first video below shows off even more angles, and the second has some of the brand's designers going in depth about the car's shape. This content is hosted by a third party.

Nissan rethinks the compact hatchback: Introducing the Sway Concept Bold design theme showcases new design language Edgy exterior matched by elegantly simple interior Created to bring fresh, high-end thinking to compact hatchback segment GENEVA – Innovative design and product planning gave birth to the Qashqai and Juke, two of the biggest automotive success stories in recent years. Now the company has applied the same radical thinking to one of the most important sectors of the market: the compact hatchback. Unveiled at the Geneva Show, the Sway is a glimpse at how a future generation of compact Nissan models might look if the company's striking new design language was applied to a European hatchback.
