Watch the Porsche 911 GT3 RS become Lego reality

Lego might be a child's toy, but it enjoys a large following among adults. This has bred highly advanced, detailed creations, some of which take hours to build. Like the Porsche 911 GT3 RS Technic kit. The 2,704-piece kit's detail is remarkable. But the sheer array of parts doesn't really explain how long it takes to put together. For one, Brick Builder's 25-minute video, embedded above, is a time lapse. Yes, a 25-minute time lapse. It shows an assembly guide with 856 individual steps that looks like it's about two inches thick. There are less detailed owner's manuals. The video itself is mesmerizing. Watching each individual part come together into recognizable components is just like watching an actual car being assembled, only it's plastic instead of metal. In fact, guessing what the components will become is a big part of the fun. If you just want to see the body come together, you'll want to fast forward to segment three, around the 16-minute mark.

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.
