Renderings may show upcoming BMW 4 Series Gran Coupe

We've already shown you spy images of the latest member of the BMW Gran Coupe family, the 4 Series Gran Coupe. Following the trend of the larger 6 Series Gran Coupe, the 4 Series variant grafts a spare set of doors onto its two-door body.
Now, the f30post forum has come up with what it says are patent drawings of the new 4GC (originally from Chinese site Autohome.com), giving a glimpse of what the coupe-sedan-thingy looks like without its camo in the way. What we're seeing is seemingly a mix of the 3 Series GT (noticeable around the rear window) with the larger Gran Coupe styling, while retaining the current 4 Series front end.
We can't say it looks great, but as these are merely renderings, it's far too early for us to come to a final conclusion on the overall look of the 4 Series Gran Coupe. Have a look up top at the patent images. We've also included our spy photos of the new Gran Coupe below. Let us know what you think of the latest niche product from BMW down in Comments.

Watch the BMW M4 GTS lap the Nurburgring in under 7:28

When BMW unveiled the new M4 GTS back in October, it said it could lap the Nurburgring in 7 minutes and 28 seconds. That's all well and fine in terms of bragging rights, but what Bimmer enthusiasts have been waiting for is the proof. And here it is, in ultra-HD 4k glory. In the video above, you can see the new M4 GTS scything its way through the Green Hell of the Eifel mountains. Behind the wheel is M GmbH engineer and racing driver Joerg Weidinger, who helpfully narrates the video to show us exactly how he tackled each and every corner along the 14-mile circuit. Which may come in handy for those with a season pass to the Nordschleife, but the rest of us are more concerned with that lap time and how it holds up. To put it plainly, the 7:27.88 lap makes the new GTS not only the fastest in the M3/M4 line to date, but the fastest production Bimmer ever clocked around the 'Ring. It handily beats the previous M3 CSL (7:50) and the stock M4 (7:52), and even trounces more powerful Bavarian machinery like the Z8, M5, and M6. There've been a handful of BMW-powered racers, motorcycles, and prototypes (not to mention the McLaren F1) that have clocked faster times, but as far as four-wheeled, standard production Munich-mobiles go, the new M4 GTS is the new King of the Ring. It also just so happens to match or beat the best times clocked by the more exotic likes of the Ferrari 458 Italia, McLaren MP4-12C, and Porsche Carrera GT – putting the M4 GTS in rare company indeed.

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.
