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 iPerformance plug-in hybrids coming in July

BMW obviously has a long-term plug-in vehicle plan. Like megacity long. First hinted at in 2008 and finally announced in 2009, the Bavarian's EV march has gone through the MINI E, the ActiveE, and then the i3 and i8. There's got to be a detailed timeline chart taped to an office wall in Munich somewhere that we would love to get a glimpse of, but instead we just get bits and pieces of where BMW's going next. At least now know the next phase: iPerformance. The new iPerformance models will be vehicles from the core BMW line-up that have plug-in hybrid technology that was first used in the i3 or i8. This technology includes the, "electric motors, battery cells and electronic control systems" and the first models to use some of the i Brand guts will be the plug-in hybrid versions of the 7 Series, like the new BMW 740e iPerformance. BMW is also going to throw in some of the now-standard blue accents that you might be familiar with form the i3 and i8, in case you don't recognize the outlet panel. As for the continuation of the i vehicles (currently just that two-model line-up), we still don't know anything other than the rumors of an i5 or i6 or who knows what. You can read the full release about iPerformance below.

The first ever M Performance TwinPower Turbo 12-cylinder petrol engine generates 441 kW/600 hp* and sprints from 0 to 100 km/h / 62 mph in 3.9 seconds* (fuel consumption combined: 12.6 l/100 km [22.4 mpg imp]; CO2 emissions combined: 294 g/km)**. The new iPerformance model designation, which will be given to all BMW plug-in hybrid vehicles from July 2016, provides a visible indicator of the transfer of technology from BMW i to the BMW core brand. It will be seen first on the plug-in hybrid variants of the new BMW 7 Series, e.g. the BMW 740e iPerformance. The iPerformance models will benefit from the transfer of technical expertise regarding electric motors, battery cells and electronic control systems. Visible indicators, meanwhile, are a BMW i logo on the front side panel, BMW i-style blue elements in the kidney grille and wheel hubs, and an eDrive logo on the C-pillar. Customers can also make use of the BMW i 360° ELECTRIC range of products and services, including the BMW i Wallbox.
