Prepare for Ludicrous Speed! Porsche 918 Spyder Featuring Our Exclusive Test Final results




Hi-Po Silver! Porsche’;s 918 Spyder is the quickest production vehicle however. Here’;s how it makes the numbers.






Flush as we are with nutty overall performance automobiles at the moment, we should keep in mind that automobiles as swift as the Porsche 918 do not come along also frequently. In 2008, the quickest (and quickest) production automobile we had ever tested was the Bugatti Veyron 16.4. It could hit 60 mph in 2.5 seconds and burn the quarter-mile in 10.1 ticks. The Porsche 918 crushes the original million-dollar car with a 2.2-second sprint to 60 mph and a 9.8-second quarter-mile time. To place that in perspective, .3 second is about how extended it takes you to blink. As acceleration instances shrink, their deltas grow to be increasingly larger percentage gains, so the 918’s third-of-a-second edge over the Veyron represents an astounding achievement. To wit:


Virtually any automobile sold in America can hit 100 mph. Plenty can even hit a prime speed of 150. So if all you wanted were speed in this planet, you could get it cheaply. But what you actually want is to minimize the time it takes to go from zero to 60. You want the capability to alter path at high speeds whilst keeping control of the automobile. You want the capability to brake speedily. You want to drift the vehicle sideways at higher speeds, as advertisements of sporty autos are compelled to show on tv. These functionality features garner premium rates in any automobile line.


And they are all exhibitions of acceleration—legal in most locations across the universe.


Algebra issue of the day: 2 918s accelerate from rest in a one-mile-long tunnel from opposite ends. What is their closing speed at the center of the tunnel?


Answer: Greater than 350 mph.






Launch handle requires the guesswork out of testing the 918. 2 electric motors with a combined 285 horsepower operate in concert with the flat- crank, 608-hp 4.6-liter V-8. By routing torque— as much as 830 pound-feet—to all 4 wheels, the 918 maximizes traction.


If we had a small much more testing space, we may have been able to hit 200 mph and dethrone the Veyron’s 25.5- second zero-to-200- mph time. (It is also the only auto for which we have that stat.) But even Porsche admits that the Veyron accelerates tougher at higher speed.






Glancing at the speed show for half a second although going 187 mph— the fastest speed we achieved—makes 137 feet of road disappear. That’s 5 feet much less than it requires the 918 to quit from 70 mph in a full panic circumstance.






There is very little wheelspin throughout the 918 launch. But assuming for a moment that there is no at-launch wheelspin whatsoever, the 918 jumps to 16 mph after just one particular wheel rotation, or in about 6 feet. Its massive 325/30ZR-21 Michelin Pilot Sport Cup 2 rear tires ($ 729 apiece) stand almost 29 inches tall, practically 2 inches taller than a 911 Turbo S’s rear rubber. Escalating the general diameter of a tire increases the location of the get in touch with patch. That is why Leading Fuel dragsters’ tires are engineered to expand in response to inertial forces at launch. Widening the tires assists to increase the lateral limit.
