From The Age

"Porsche has announced an official Nurburgring lap time of 7 minutes 14 seconds for its upcoming 918 Spyder following a series of tests with prototypes of the advanced new petrol-electric hybrid supercar at the famed German circuit this week.

Although Porsche isn’t prepared to confirm who was driving the early version of the 918 Spyder at the time, it does say the lap time was achieved with a prototype boasting what it describes as an optional Weissach package that brings a six-point racing harness, upgraded brakes and various weight trimming measures and on standard Michelin road tyres.

“With a time of 7 minutes 14 seconds the 918 Spyder has confirmed the potential of its future orientated driveline concept after just a few months of testing,” beamed Frank Walliser, head of the 918 Spyder development, who was on hand to witness the new car's hot lap.

The official lap time for the 918 Spyder is among the fastest for a road legal car at the Nurburgring’s northern circuit, undercutting the fastest time of its predecessor, the Carrera GT, achieved back in 2004 by some 18 seconds.

As well as confirming the 918 Spyder’s testing pace at the Nurburgring, Porsche has also revealed its new range topping model’s hybrid driveline boasts an official 585kW.

Power for the carbon fibre bodied two-seater hails from a mid-mounted 4.6-litre V8 petrol engine based on the unit originally used by the Porsche RS Spyder race car as well as a pair of electric motors mounted within the front axle assembly, with drive going to either the front wheels in pure electric mode, the rear wheels (when powered by the petrol engine) or a combination of all four (when accelerating hard).

By comparison, the Carrera GT’s naturally aspirated 5.7-litre V10 petrol engine kicked out 450kW."

And for those interested, you can start deciding on colours and wraps/graphics...

The GT2 RS did a 7:18 and the GTC did a 7:28.

For those interested, the fastest time ever was 6mins 11sec by Stefan Bellof in a 956 in 1983. :)

Anyhow, its a great car.

Darn right, JJ.

To give you an idea of just how fast the 956 race car was.

At Silverstone in 83 he was on pole with 1m 13.5sec, would have put him 12th on the grid for the F1 race at the same track that year.

As far as great race cars of all time, the 956 is hard to beat. :)

And here she is.

Porsche said (regarding the 918) the time was "one of the best ever recorded for a street-legal vehicle with standard tires," and was "particularly impressive as it was achieved from a standing start."

Porsche 918 Spyder plug-in hybrid hits the track


Posted on September 24, 2012 - 18:28 by Pete Danko, EarthTechling

For those of you saving up the $845,000 you'll need to purchase a Porsche 918 Spyder plug-in hybrid, we have good news. No, the price hasn't come down - but it is as fast as originally advertised.

Porsche, in one of those whetting-the-appetite news releases, said the supercar prototype zipped around the 12.8-mile Nürburgring Nordschleife (a twisting and turning and rising and falling track in the Eifel mountains) in 7 minutes and 14 seconds.

That's an average speed of 106 mph.

[the fastest F1 lap ever on the old Nordschleife, Niki Lauda’s pole position for the 1975 German Grand Prix: at 6:59 and an average speed of 121.96 mph - http://jalopnik.com/5599675/what-the-pagani-zonda-rs-insane-nurburgring-record-really-means]

That was enough for Porsche to shout "success!"

"With the time of 7:14 minutes, the 918 Spyder prototype is already proving to be a fully sustainable concept after just a few months on the road," Frank Walliser, head of the 918 Spyder project, said in a statement.

Porsche said the time was "one of the best ever recorded for a street-legal vehicle with standard tires," and was "particularly impressive as it was achieved from a standing start."

Standing starts should be no problem: Porsche said earlier this year that in electric only mode it could go from zero to 60 in three seconds. The all-electric range is said to be 15 miles, which means the car could have completed the Nordschleife using no gas. 



However, since the top electric-only speed is 90 mph and the PEHV averaged over that, clearly it took advantage of the 570-hp, 4.6 litre V8 engine, which helps give it a top speed of 200 mph. 

Limited production (duh) of the vehicle is expected to kick off in fall 2013.

Riding Shotgun in the Porsche 918 Spyder

Don't let the Porsche 918 Spyder's princely $845,000 price tag or its 795-hp output distract you. This plug-in hybrid's most telling number resides in its model name.

That 918 badge implies that this two-seat plug-in hybrid is a spiritual successor to the legendary 917, an incredibly successful race car whose later iterations boasted in excess of 1100 horsepower and a notorious appetite for victory. If that doesn't speak volumes to the 918's stratospheric ambitions, consider the other figures surrounding this low-slung sled: a Nürburgring lap time of 7:14 (20 seconds faster than its V-10-powered ancestor, the Carrera GT), an electric motor that produces a 442 lb-ft plateau of torque between 1000 and 9000 rpm, and an improbably high 78.4-mpg fuel-economy estimate that defies those outrageous performance specs.

We went for a ride in a Porsche 918 Spyder prototype a year in advance of its build date—which, you guessed it, is Sept. 18, 2013. Here's what we learned.

The Tech: One High-Strung Hybrid

There's a point to this bonanza of incomprehensibly complex technology: The 918 Spyder serves as a bleeding-edge testbed for future Porsche hybrids and a dramatic statement about the company's engineering prowess. Built around a carbon-fiber-reinforced plastic tub, this amalgam of internal combustion and electric power constitutes a wish list of ultra-high-performance components.

The fossil-fuel-burning part of the equation consists of a dry-sump-equipped 4.6-liter V-8 that spins 580 hp at a screaming 8500 rpm. That's 50 more hp than the LMP2 race car from which the mill is derived. Rear power is driven through a seven-speed Doppelkupplungsgetriebe (PDK) transmission adapted from the 911 Turbo S.

Assisting the internal combustion effort are a 95-kilowatt hybrid module at the rear axle and an 85-kw electric motor driving the front. Together they can pump out 795 hp. A separate gearbox diverts electric power to the front wheels, decoupling above 146 mph. Power is stored (and regenerated into) a liquid-cooled lithium-ion battery with 312 individual cells, which can also be charged using a household 110-volt plug. And 55 control units manage the interplay between fuel and electric power. Because efficient performance is the name of the game, there was no consideration given for a hydraulic steering system; the 918 Spyder uses an electromechanical setup with a rear steer feature, which can countersteer to offer quicker turns at low speeds or turn in the same direction of the fronts at higher speeds to prevent the tail from kicking out.

A small red steering wheel button lets you select from five options for the hybrid powertrain: E-Power (all-electric, which can run for up to 16 miles), Hybrid (which uses gas and electric power for maximum efficiency), Sport Hybrid (a more aggressive version of Hybrid), Race Hybrid (in which the electric motors offer short bursts of high output), and Hot Lap (which drains the batteries in an all-out attempt for maximum speed.)

Active aerodynamic features include air inlets below the headlights, a rear wing that deploys and alters the angle of attack, and underfloor air flaps positioned ahead of the front axle to direct air into diffuser channels. The 918 Spyder is expected to tip the scales at 3747 pounds, or 3670 pounds with the stripped-down Weissach package.

The Ride: From Silent to Speeding

We conducted our shotgun ride in a Porsche 918 Spyder on the roads surrounding Germany's famed Nürburgring, where the car later turned in its previously mentioned astounding lap time. Our tester, which was one of 20 or so preproduction vehicles in existence, wore an exterior that's about 80 percent complete, according to one Porsche engineer, and mechanical components that are roughly 70 percent finished.

At idle in the Nürburgring pits, you might never guess that this waist-high prototype is capable of neck-snapping performance. Yes, heat rises with menace from the rear decklids (during development the exhaust pipes migrated to an upward position because that was the only way to manage the intense thermal interplay between battery and internal combustion). However, the sound coming from the V-8 is raw and unrefined.

Still, there's plenty of acoustic tuning that will help make the 918 sound expensive once it actually hits the market. The roadster's seat-of-the-pants impressions reveal far more about how this complicated beast operates.

As we pull out of the pits in EV mode, the nearly silent whir of the electric motor replaces the din of the V-8. This Porsche tester being a work in progress, there are still some driveline noises and high-pitched frequencies making their way into the cabin. But, apart from the bulky diagnostic equipment and cobbled-together interior parts, the 918 scoots along with potent authority.

As the driver selects Hybrid mode, the V-8 comes to life, acceleration gets noticeably huskier, and all four wheels do their part to pull the 918 ahead with alacrity. The engine shuts down and fires up intermittently in this mode, and while the transition feels somewhat (but not entirely) seamless, the underlying grunt feels satisfyingly robust.

That is, until we experience a brief but intoxicating stretch in Race Hybrid mode, which reveals the 918's ability to dart forward with long-legged insistence, digging into tarmac with Michelin tires that seem to accelerate, brake, and corner with more g-forces than should be possible from efficiency-minded rubber. That momentary dalliance with thrust is a tasty tease into what promises to be a full repertoire of relentless, jaw-clenching performance.

The Bottom Line: The Trickledown Effect

The Porsche 918 Spyder's personality might be defined by numbers: 0-to-60 mph in under 3 seconds, 78.4 mpg (which will likely drop when the EPA offers it own rating), and that outrageous Nürburgring lap time. Yet the true magic of this car lies in how its traditional internal combustion marries to the techy world of hybrid powertrains.

Only 918 paying customers will be able to pony up the near-seven-figure price tag to have their own 918. But this most technologically ambitious Porsche will eventually be known as the car that enabled exotic hybrid drivetrain components to trickle down into more accessible cars. And for that, the 918 Spyder is a perfectly justifiable exercise in excess.

So just as we saw alot of the mechanicals from the 959 trickle down to volume models, notably the twin turbocharging and all wheel drive systems and recently 'torque vectoring', can we expect to see more hybridization between IC and electric motors?

Is the move to electrically assisted steering a precursor to an expanding repertoire of electrics?

Will the next boxster be a low boost 4 cyl 2lt T engine coupled with an electric motor?

http://www.motorauthority.com/news/1056922_more-talk-of-porsches-four-cylinder-boxster-cayman-plans

Are we going to see a Turbo 911 with batteries?

Is taxing carbon a pre-emotive move to secure revenue as we replace fossil fuels with electrics to power vehicles?

I feel the weaning coming...

Math doesn't make sense....................

When Lauder did the Ring in under 7 it was 2 miles longer than it is today!!!!!!!!!!!!!!!!

Now that is quick!!!!!!!!!!
