Rinspeed Budii Concept is a rolling smorgasbord of future tech [w/video]

There's a strange dichotomy going on inside the Rinspeed Budii Concept. Actually, there's a slew of seemingly mismatched ideas, but that seems par for the course when it comes to the mind of Frank Rinderknecht, no? For instance, there's a manual-wind Manero PowerReserve watch embedded in the cabin, which seems quaint, considering the high-tech nature of the car's design and intent. A high-resolution camera apparently "recognizes" when the watch is getting low on power, and a robotic arm "uses ingenious motions to wind the movement" of the watch. Seriously. The aforementioned robotic arm is a seven-axis unit that can "reach out" to the driver or passenger so that they can take over driving duties from the autonomous car. In this way, the occupants can choose to put their lives under the control of the "cognitive and intuitive autopilot" provided by a telescoping laser scanner and a high-res camera that map the car's surroundings, or to make their own "ethical" driving decisions. We kind of assume that refers to the current autonomous-driving question of the times: whether or not to save the lives inside the car our outside of it in case of emergency. If all of that sounds suitably high-tech, you should also know that the "feel-good lounge atmosphere" of the interior features removable plexiglass work surfaces inside, folding blinds for privacy that are custom printed with user-selectable designs, air outlets with ambient lighting, a "wellness shower in the headliner" (whatever that means) and a center console with – you guessed it – cup holders. The platform on which all of this is based is the all-electric BMW i3 hatchback. If all of that sounds intriguing, we suggest you read all about it in the press release below and take it all in via the included image galleries. 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 i5 could be a new kind of i PHEV

Just this month BMW North America CEO Ludwig Willisch made a point of saying "Not any time soon" to AutoblogGreen's question about the arrival of a BMW i5 - and that came after he clarified, in case we didn't know it, that no such model exists. But the rumors of its eventual appearance were swelled again by a report in Autobild that sticks more details and numbers on what could be the next offering in for the i brand. In February, Car magazine laid the i5 out as having a 245-horsepower four-cylinder engine in front, assisted by a 204-hp e-motor in the bow and a 90-hp e-motor in the stern, for about 544 total horsepower. Autobild claims the gas engine will have 218 hp, the front e-motor will have 150 hp and the rear will have 272 hp, for roughly 640 total horsepower. Where the two reports agree is that it - maybe called i5, maybe i7 - will be based on the China-market long-wheelbase 5 Series platform, it will incorporate cues from both the 7 Series and 6 Series Gran Coupe, and it will not be cheap: 100,000 euros ($105,686 US) is the estimate. The i8 starts at 130,000 euros in Germany. Weight for the i5 is figured to be around 3,300 pounds. Green Car Reports says what's important about the i5's drivetrain is that it's being maximized for electric running. Its evolution of the company's eDrive mechanicals will crank the ICE over only above 36 miles per hour, and even then, only in cases of "maximum power demand." Electric-only driving would offer a range of 78 miles, company officials suggesting that it could remain in that mode for "fully two-thirds of its usage cycle." Whenever a vehicle like this arrives, that is, which Autobild says could be in 2019.
