Rinspeed issues its Budii call for Geneva [w/video]

Of all the concepts prepared every year for the Geneva Motor Show, those made by Rinspeed are typically the most outlandish and forward-thinking. And this is the latest from Frank Rinderknecht and company. Though Rinspeed's been known to build entirely original vehicles from the ground up, it tends to base its creations on production models: Following the Tesla-based XchangE from last year, the Smart-based Dock+Go of 2012, the Fiat-based E2 from 2009 and the Lotus-based sQuba in 2007, the new Budii concept is based on the BMW i3. That means, of course, that it's powered by electricity, but the technology demonstrator is focused more on autonomous driving tech. The Budii incorporates a periscopic camera and laser scanner to map the terrain and the road ahead from above, and a drive-by-wire steering system that allows the steering wheel on an articulated column to be passed between driver and passenger or tucked out of the way to let the electronics take over. Once unburdened of the task of driving, the occupants can enjoy the proliferation of touchscreens, the "wellness shower" (whatever that is) installed in the headliner, the automatic watch-winder on the steering column and the interior accoutrements furnished by Mansory. The whole thing rides on a lowered suspension with 19-inch Borbet alloys, with a rainbow Knight Rider-style grille in the nose. But to appreciate the full scope of the consortium of suppliers that collaborated with Rinspeed to bring the Budii to life, you'll want to delve into the press release after the video below and scope out the dozens of high-resolution images in the slideshow above. 2015 Geneva Motor Show: Rinspeed "Budii" redefines human-machine interaction Reach out to robots The vision of autonomous driving will soon become reality and will fundamentally change the interaction of man and automobiles. While the research centers of the automotive industry are still feverishly working on the technical solutions, progressive thinkers such as the Swiss idea factory Rinspeed are already giving concrete thought to how automated private transport will transform the car and the man-machine system. Besides fundamental conceptual changes, this will also have to involve issues of ethics and society. In the past, the robots in the factories of this world merely assembled cars for people.

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.

BMW 2 Series Active Tourer pulls its way onto the stage

We know what you might be thinking: here comes another BMW with yet another kind of roofline. Only this isn't just another BMW. It's the first front-drive BMW, and the first time we've ever seen it in person.
That model, of course, is the new 2 Series Active Tourer, debuting here in Geneva as the production version of the Concept Active Tourer and the beefier Concept Active Tourer Outdoor that followed. It shares about as much with the 2 Series Coupe as a jelly donut, but takes BMW into a new market segment - that of the high-roofed hatchback (or micro-minivan, depending on your perspective) occupied by the likes of the Mercedes-Benz B-Class and Volkswagen Golf Sportsvan.
Power comes from a choice of 1.5-liter turbo three, 2.0-liter turbo four or 2.0-liter turbodiesel - but aside from the forced-induction engines what they all the versions have in common is what makes the 2 Series Active Tourer newsworthy: they all sit up front, driving the front wheels. It's an idea BMW purists might not appreciate, but one we'd all better get used to just the same.
