Porsche purists, look away: This 911 is powered by Hyundai

Bisimoto appears to be putting together a Hyundai V6-powered Porsche 911. While the experiment reminds us of a project from earlier this year, in which Ryan Tuerck dropped a Ferrari V8 into Toyota GT86, this one's a bit different. Bisimoto has a history of creating some truly insane automobiles, usually with Veyron-menacing power levels. In fact, the tuning company built multiple 1,000 horsepower machines, including a 1976 Porsche 911 and a 2013 Hyundai Genesis Coupe, not to mention a few other Hyundais with oodles of power. So it seems Bisimoto has decided to combine the company's experience with both marque's into one machine with this 1977 Porsche 911. This content is hosted by a third party.

No specific details about the engine were given, but a "hyundaiusa" tag, some helpful hints from Instagram commenters and some diligent Google image searching by Autoblog staff members seem to show that this is a Hyundai Lambda series V6. It also appears to be a version from a car with a transverse layout, which would make it easier to fit in the 911's traditional engine location. What we do know is that the build will be completed in time for the SEMA show, and we look forward to seeing the finished Franken-Porsche. The same probably can't be said for Porsche purists though.

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.

Porsche Cayenne shows a bit more face, plug-in spotted

Porsche was first rumored to be working on a plug-in hybrid (PHEV) version of the Cayenne over a year ago. However, we had never seen it, until now. The new model was caught almost completely undisguised while testing. In another stroke of luck, we got a glimpse of the upcoming facelift for Porsche's SUV (pictured above) as well.
According to the spy shooter, it was windy during the cars' cold weather testing. The cover blew off of the facelifted Cayenne, and there was enough time to snap these pictures before it could be hidden again. The changes are all quite minor but jive with what we saw the last time it was spied. The rear still wears some cladding but is expected to be hiding lights similar to the Macan.
The second gallery shows off the upcoming Cayenne PHEV. It looks nearly identical to the standard model, except for the extra panel on the driver's side of the car that hides the electric port. One image even shows the car plugged in. The new version is expected to use the same supercharged 3.0-liter V6 and 9.4-kilowatt-hour lithium-ion battery pack with a combined 416 horsepower and 435 pound-feet of torque from the Panamera S E-Hybrid. We enjoyed the system when we tested it last year. It's rumored to debut on the SUV sometime this year.
