Chris Harris brings together the 918 Spyder, LaFerrari, and P1

The Porsche 918 Spyder, Ferrari LaFerrari, and McLaren P1 show that a hybrid powertrain can make for blistering performance despite its electric assist. This trio doesn't arrive on track together very often, but Chris Harris assembled these three stars at the Portimao circuit for a nearly hour-long demonstration of their amazing capabilities. So, which one is quickest around the track? Harris provides an answer with in-car video of all three contenders. His team also goes out of its way to even the playing field by sourcing tires independently from Pirelli for the P1 and LaFerrari. With the technical part out of the way, Harris can start having fun by doing his usual slides during the driving comparison. Tiff Needell and Marino Franchitti also eventually show up to provide the perfect recipe for a track battle in these hypercars. If you don't have the time, skip about 14:25 into the clip just to see the lap times. However, those numbers only tell a tiny part of the story. The whole video is definitely worth a watch.

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.

All Porsche 911s to get turbos in 2015?

Currently, Porsche builds two turbocharged 911s - the Turbo and the Turbo S (and their cabriolet counterparts). The rest of the 911 range, meanwhile, is motivated by either 3.4- or 3.8-liter flat-sixes of varying outputs. This clear separation could be set to change in the very near future, though, as rumors continue to swirl that Porsche's rear-engined range could switch exclusively to turbocharged power.
This time, it's Car projecting that the 911 range will go turbocharged as part of a mid-cycle refresh, with the base Carrera's 3.4-liter dropping to 2.9 liters and adding an iron lung, bumping the entry level 911 up to 400 horsepower. Yes, a 400-horsepower, entry level 911. The Carrera S, meanwhile, will retain its 3.8-liter engine, but will also benefit from turbocharging, increasing output to 530 horsepower and 520 pound-feet of torque. So basically, it sounds like the current, 520-hp 911 Turbo will become the next Carrera S.
What does that mean for Porsche's traditional high-performance models? Well, it's a safe bet that the Turbo, Turbo S and eventual GT2 will be producing seriously huge power figures. Based on pure speculation, we wouldn't be shocked to see a 600-hp Turbo, with the S and GT2 increasing output markedly from there.
