BMW M3 gets the video retrospective treatment

With BMW on the cusp of pulling back the sheets on its next-generation M3 (or should we say, M4?), the crew from Electric Federal has taken it upon themselves to give us a generation-by-generation look at the evolution of the most renowned of BMW's sports coupes. The video below features plenty of beautiful shots of each generation of M3, starting with the ever lust-worthy E30 before finishing up with the current iteration. BWS Motorsport's Mark Norris provides the narration, complete with a brief synopsis of what makes each generation so special.
As usual, the clip is fit for big-screen viewing. You can watch the action below for yourself. Meanwhile, we'll be busy figuring out which vital organs we can sell to get our hands on our own E30 M3.

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 8 Series coming in 2020

As good as the BMW 7 Series may be – and trust us when we say it is very good indeed – it just can't compete with the marketplace juggernaut that is the Mercedes-Benz S-Class, at least not where global sales are concerned. And with sales come profits, especially at the six-digit price point many of these high-end luxury cars sell for. Put simply, Mercedes is cashing in on the S-Class, and BMW wants a bigger piece of that pie. It comes as little surprise, then, that Autocar reports BMW is currently considering two proposals for a new 8 Series that would slot just above its current 7 Series. One option is the currently-en-vogue four-door coupe. The other option is a more traditional two-door coupe, likely with a cabriolet option. The last time we heard such rumors, BMW was dismissing them back in 2013. Whichever way BMW decides to take its 8 Series plans, Autocar suggests that a concept vehicle ought to hit the show circuit in sometime in 2018, with a production model following in 2020. The car would be based on the underpinnings of the latest 7 Series, with a price considerably less than the Rolls-Royce Ghost (which also falls under the BMW umbrella). Considering BMW's penchant for multiple model variants, we won't be surprised if all three options get the green light, with a Gran Coupe version standing as the flagship. With the 6 Series Gran Coupe currently priced just below the 7 Series (and at a hefty premium to a comparable 5 Series four-door), an 8 Series would likely brush up against $100,000 for a base price. That might not take much out of S-Class sales, but it would make some tidy profits for BMW. Related Video:
