2014 918 Spyder Prototype Picture


We arrive at Nardo at daybreak. We slept an hour last out of nervous anticipation for what today: a ride in a 2014 918 Spyder prototype, the only one in the It’s still winter in the of Italy, but the air is warm and there’s a sky overhead.

This is good because multimillion-dollar development and rain don’t mix.

A Multivan deposits us at the remote track where we find a of Porsche engineers at work, by all sorts of data-logging equipment. And in the middle of it all, is the 918.

The ever Porsche 918 Spyder to run its own means is nothing more a rolling chassis pieced so engineers can test its gasoline-electric drivetrain. Partly covered in Porsche 911 body panels and outrageous exhaust pipes sprout up from the engine bay at the (a feature we’re assured be retained for production), it is a long way the 918 Spyder concept that in the spotlight at the 2010 Geneva Show.

Will Look the Concept Eventually

The production will be very similar to the car in overall appearance, Frank chief engineer for the 918 program, us. There will be some like these tailpipes. is really just a systems that we’re using to the various gasoline-electric hybrid and its electronics package before we construction of road-going prototypes in Weissach (Porsche’s research and center in Germany).

You should the Porsche 918 Spyder by now. months after its unveiling, confirmed it would put the targa-roofed into production as a successor to the Carrera GT. starting on September 18, Just 918 examples are planned, running down a dedicated that is being established in a paint shop at the carmaker’s headquarters in Germany.

It is the same factory that the latest Boxster and 911 a holy to true Porsche fans, no

Waking Up the Engine

The Porsche make some adjustments to the electronics, which are housed in a aluminum box strapped to an area will eventually be occupied by the car’s rear spoiler. boss, Wolfgang Hatz, chief of research and development, down into the driver and twists a key in the left-hand-mounted ignition. Odd sounds rise up from before the gasoline engine and fills the garage with a pulsating blare of exhaust those prominent tailpipes.

The of the new Porsche is its mid-rear-mounted V8 gasoline seated on traditional rubber (rather than the hydraulic used on the 911) within a cradle that is attached to the of the main tub by six prominent mounting Similar to the 90-degree V8 used in the RS Spyder successfully campaigned in the Le Mans series between and 2008, the engine has gained 1.2 of displacement, going from 3.4 in race trim up to 4.6 liters in application.

Walliser describes the as entirely new, noting it features an all-new crankcase, head design and low-reciprocating-mass plus that radical system that sees two exit just behind the carbon-fiber roll hoops. The of this arrangement is to keep hot gases well away the car’s heat-sensitive battery mounted down low directly the tub.

Let’s Talk the Numbers

The revamped V8 has been to rev to a dizzying 9,200 rpm (though in its state of tune, it has a lower and owing to its racing gene, promises it will deliver the razor-sharp throttle response as the GT’s 5.7-liter V10. engineers tell us the V8 makes 562 horsepower.

But the 2014 Porsche 918 Spyder is a remember, so it also has a pair of electric motors one mounted up acting exclusively on the front with 107 hp, and a second, 121-hp attached to the rear of the gasoline providing drive to the rear We’re told total power will be in the neighborhood of 759 hp, 568 pound-feet of torque.

Barely his delight at finally getting to off the 918 Spyder to someone other an engineer, Hatz gingerly the prototype out of the garage. After the throttle a couple times to some heat into the and its peripheries, he speeds off into the We scramble back into the and catch up with the prototype at the end of an test track.

The engineering has spent the last 10 days methodically running through the systems test of the new car.

How It All

Like the Cayenne and Panamera the 918 is a parallel hybrid, but its electric are obviously a lot more powerful and its pack is bigger (Porsche released a kWh capacity rating, but we there are 312 lithium-ion cells at a maximum 202 kilowatts). The Spyder can be in either all-gasoline or all-electric or when added performance is for, a combination of both. In mode, it has a claimed range of 16 at speeds up to 93 mph.

Electric for the battery pack is collected on the and during braking via a recuperation claimed to operate up to three more efficiently than the on the Cayenne and Panamera. You’ll be able to plug this car in, an anticipated recharge time 2 and 6 hours, depending on the available

Depending on which engine motor combination is in use, the 918 is either rear-drive or all-wheel The front electric motor a direct-drive unit, and an electronic function apportions torque the front wheels to benefit The Porsche engineers tell us drive to the front wheels is at 146 mph to improve high-speed stability.

the gasoline V8 and rear electric are mated to Porsche’s seven-speed, automated manual PDK transmission, drives the rear wheels the help of a torque-vectoring system and locking differential.

Finally, Our Turn

Hatz folds in two and uneasily steps out of the precious wearing the biggest smile ever seen and, some data-logging equipment is to various VGA sockets, diminutive test driver Holger takes his place behind the We’re then asked if like to be the first of a small of media to ride in the 2014 918 Spyder. We’re halfway the cabin, tripping over the sill, before we remember to

It’s snug, dark, and a complete mess in the 918 prototype. the production car is set to receive a removable panel, the prototype sports a structure. There’s a three-spoke wheel from the 911, pack from the Boxster and a cast-aluminum gear selector, a sea of blue wires in front of our which is borrowed from the 911

There’s an 18.5-gallon gas tank behind our seat. Almost Bartels tells us this all change by the time the new car reaches For now, it’s one hell of an

Beside us, Bartels points the down a long straight. We beyond the 93-mph all-electric and the gasoline engine booms to There’s still a lot of tuning to be done, but the free-revving V8 instantly an added dimension to the performance in terms of outright pace and attributes.

Still, more to this latest supercar than straight-line Walliser also claims the version will be capable of 78 mpg combined on the European test It’s a headlining figure, of achieved primarily on electric

But even when driven for the 918 Spyder will be capable of more than 30 mpg, told.

With a deft flick of the shift paddle, Bartels down to 5th gear, then and then he just stands on the which include giant front carbon-ceramic discs and discs in back.

What About the

The 2014 Porsche 918 Spyder rides on a unique chassis almost entirely from components. The suspension is a combination of wishbones at the front and a multilink in back, but unlike the system on the GT, which used a racecarlike system attached to the unit-body, the 918 has springs and dampers sited near the center-lock-style wheels, measure 20 inches up front and 21 in the rear and are wrapped in 265/35R20 and Michelin Pilot Sport Cup

It is all attached to the car’s ultra-stiff structure manufactured by Austrian CarboTech via solid metal The dampers are adaptive, altering comfort and sport modes at the of a button on the center console in with the PASM (Porsche Suspension Management) already on each and every Porsche these days. To ease into suburban driveways and expensive underbody scrapes on lot ramps, the front end offers 1.2 of ride height adjustment.

As on the 911 and Boxster, the steering uses power assist and automatically steering lock to compensate for such as stiff side It also provides a small of steering angle to the rear reducing the turning circle at speeds.
