Porsche completes production of 918 Spyder

Porsche is closing another chapter in its history as production of the 918 Spyder has officially come to an end. The only remaining question is: what comes next? The 918 was the latest in a long line of flagship supercars from the German automaker, starting with the 904 Carrera GTS, continuing on through the 959, 911 GT1, and Carrera GT. Each was a technological game-changer for Porsche, just as the 918 Spyder will surely be remembered. With the hybrid roadster now zipping off into the annals of history, all eyes will be fixed on Zuffenhausen to see what it does next. And though it may not be much to go on, we've already begun seeing some hints at what that could be. Last week Porsche released a solitary teaser image showing its next-generation sports car, covered and parked alongside the Le Mans-winning 919 Hybrid LMP1. Just what's under the cover, Porsche isn't saying, and didn't respond to our repeated inquiries for comment. However the signs point towards a mid-engined supercar – not unlikely to pack a hybrid powertain once again – positioned closer to the likes of McLaren 650S and Ferrari 488 GTB than the outgoing 918 Spyder, which faced off against the McLaren P1 and LaFerrari. If that turns out to be the direction Porsche takes with its upcoming new supercar, as has long been anticipated, it would hardly be unprovoked. McLaren recently launched the 570S as part of its new Sport Series to take on the Porsche 911 Turbo, and Ferrari is once again rumored to be pursuing the same with a new Dino. While the specifics may remain cloudy for the time being, what is crystal clear is that things are about to get very interesting in the battle between Porsche and its rivals.

Today, the chequered flag marked the finish: after 21 months of production time, the final Porsche 918 Spyder came off the line in Stuttgart-Zuffenhausen according to schedule. But the legacy of this technology pioneer will reach far beyond its production time. Future generations of sports cars will benefit directly from innovations of the 918 Spyder. The 918 Spyder was systematically developed to be a performance hybrid with plug-in technology. The hybrid super sports concept car made its debut at the 2010 Geneva International Motor Show where it met with overwhelming approval.

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.

2015 Porsche 918 Spyder: Touring the factory

Willy Wonka granted just five lucky Golden Ticket holders access to his incredible chocolate factory, yet we consider ourselves just as fortunate, as Porsche invited us to be among the first of just four American journalists to see behind the closed doors of its 918 Spyder assembly plant in Zuffenhausen, Germany. Of course, there were no Oompa Loompas or flowing chocolate rivers, but the vast white hall tasked with producing only 918 examples of the automaker's limited-production flagship revealed details that make Wonka's Golden Egg sorting room seem rather mundane in comparison. Unlike a traditional automobile manufacturing plant, which often encompass all processes of making a vehicle (e.g., stamping steel panels, welding components and painting), the 918 Spyder is built in an assembly plant. This means that hundreds of already manufactured parts, each crafted by Porsche offsite suppliers, are brought under one roof to be assembled into a perfectly finished product that is much sweeter – and far more expensive – than any candy delicacy. Our tour guide was Michael Drolshagen, Porsche's Director of Production, Logistics and Quality - a walking encyclopedia when it comes to the engineering and assembly of the 918 Spyder. Drolshagen generously offered us unrestricted access to walk among the factory's 110 workers – and a couple-dozen vehicles in process – to photograph everything. This is a story best told with pictures, so we've put together a raft of our best images in a high-resolution gallery and captioned each with a detailed description.
