Porsche (finally) unleashes full, official details on 918 Spyder

Porsche has finally let released all of the details on the 918 Spyder, the German brand's challenger to the McLaren P1 and Ferrari LaFerrari, after months of leading our poor, performance-loving hearts on. The covers were lifted at the Volkswagen Group night, an enormous precursor to the Frankfurt Motor Show, and include a massive, 11,000-word press release that's attached at the bottom of this page.
The 918 Spyder features a mid-mounted, dry-sump-lubricated, 4.6-liter V8 engine that generates 608 horsepower when left to its own devices. Combined with a trio of electric motors, which produce 286 hp, the total system horsepower for the 918 Spyder rests at 887 ponies. That's less than the McLaren P1 (903 hp) and the LaFerrari (949 hp), but the Porsche is also likely to be a bit cheaper, starting at $845,000, while the McLaren will be in the seven-figure range for certain, and it will more than likely be joined by the LaFezza.
The 918 Spyder counters with a 2.8-second jog to 62, a 7.7-second run to 124 and it will hit 186 in 22 seconds.

Behold the glory of unobscured Porsche 911 Turbo bumpers

Porsche apparently sees absolutely no reason to hide the changes for the 911's upcoming refresh on any of the models. After releasing official photos of the standard version ahead of the debut, here are the Germans testing the revised 911 Turbo S at the Nurburgring with no camouflage at all. The exterior tweaks are tiny enough that maybe the company thinks no one would notice. The front bumper receives tiny adjustments, including the LED lights lengthened in the lower air intakes. The headlights are also slightly tweaked, and the taillights are the wider units from the rest of the updated range. The rear bumper receives some restyled vents at each corner, as well. The standard 911 is rumored to receive a new family of smaller displacement, turbocharged flat-six engines as soon as this year's Frankfurt Motor Show, and that leaves the Turbo in a weird place. Forced induction holds a special place in the model's lineup by denoting some of the most powerful versions. With that exclusivity possibly on the way out, Porsche might now have to find a way to keep the Turbo badge special. Related Video:

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.
