Porsche 718 Spyder et Cayman GT4 : De la route aux circuits

Porsche’s 718 Spyder and Cayman GT4 Bring Flat-Six Power Back!

While the 718 Cayman GTS brought plenty to the party, something was missing. True, the turbo four was punchier than the previous generation’s six-cylinder atmospheric, but there was something amiss. Power and torque figures, as important as they are, need urgency and an appropriate soundtrack to power a truly memorable sports car.

Rejoice, Natural Aspiration Has Returned

The thirst for that flat-six scream is something that comes up in conversation when criticizing the latest generation of Caymans and Boxsters, and the gods have listened. Sitting behind the cabin in the new 718 Spyder and 718 Cayman GT4 is a new 4.0-liter flat six derived from the 991 Carrera’s turbomotor, sans turbocharger. With GT-appropriate levels of response, a six-speed manual, and a redline of 8,000 rpm, the new powerplant promises more excitement.

The 415 horsepower and 310 lb-ft of torque are nothing to sniff at, but the takeaway is that those figures will be produced in a more rewarding way. While the torque figure is almost identical to the 718 GTS models, the peak torque is produced between 5,000 and 6,800 rpm. Where the turbo motor made that from 1,900 rpm, natural aspiration means a motor that encourages the driver to spin the motor to the stratosphere.

Both cars share the same chassis.

To keep this new powerplant eco-friendly, it sports Piezo injectors for direct fuel injection—the first time ever in a high-revving engine. In addition, the motor uses adaptive cylinder control. In part-load operation, it temporarily interrupts the injection process in one of the two cylinder banks, thus reducing fuel consumption.

Downforce and a Sharpened Chassis

Fifty percent more downforce comes from a single-chamber arch rear silencer which creates space in the rear section for a functional diffuser. To maintain a usable balance, the front employs a spoiler lip, which is flanked by air curtains that calm the air flow along the front wheels. That new arrangement makes the Spyder the first of the Boxster family to generate real downforce at the rear axle.

The new Spyder is the first Boxster to enjoy real downforce at the rear.

Both cars share the same chassis. With ball joints, a ride height 30mm lower than before, and recalibrated PSM and PTV systems further sharpen the ride. That, in conjunction with new ultra-high-performance tires from Porsche amount to a reported ‘Ring time in the 7:30-range. For Porsche’s entry level GT car to best a 997 GT3, a car with the same power output, by roughly ten seconds speaks to the extent they’ve refined the chassis. This will be a world-beater.

The GT4 also comes with the option of a Clubsport package. This includes a rear steel roll bar, a hand-held fire extinguisher and a six-point seatbelt on the driver’s side.

Porsche 718 Boxster Spyder 2020 : Le teaser est lancé

Voilà déjà de très nombreux mois que nous parlons de cette version radicale et sportive de la Porsche 718 Boxster. Depuis bien plus d’une année, nous avons été abreuvés de spyshots, de vidéos prises sur le Nürburgring et surtout de discussion enflammée autour de son groupe propulseur qui ne sera pas un flatfour suralimenté mais bel et bien un flatsix atmosphérique.

La 718 Boxster Spyder 2020 s’annonce enfin officiellement dans un petit teaser vidéo mis discrètement en ligne par le constructeur de Zuffenhausen cet après midi.
Ne vous attendez pas à découvrir le spyder allemand dans ce petit clip, tout juste l’aperçoit-on très brièvement durant les 15 secondes du clip.

Le teaser vidéo

Ce teaser confirme en tout cas les rumeurs qui veulent que la 718 Boxster Spyder 2020 soit dévoilé dans le courant de la semaine prochaine puisqu’on annonce que la nouvelle Porsche 718 Cayman GT4 Clubsport 2020 sera présentée lors du Festival of Speed qui se déroulera à Goodwood du jeudi 4 au dimanche 7 juillet prochain.

Une vidéo de la 718 Boxster Spyder en test de mise au point, il y a quelques jours sur le Nürburgring.

Tout cela demande une ou plusieurs confirmations officielles et il faudra encore patienter quelques jours pour en savoir plus.
Alors cette 718 Boxster Spyder, avec le flatsix 3.8 L ou 4.0 L atmosphérique ?

Is a 911 GT2 RS Faster Than A 918 Spyder at Hockenheim?

Unlike many cars of its ilk, this GT2 RS sees a great deal of track time. Whether it be racing against current GT3 Cup cars or highly modified Nissan GT-Rs, sebastian vittel’s RS is a regular sight at tracks across France and Germany. It’s been given a few tasteful modifications to suit it to the regular beating it takes; utilizing Endless pads, steel brakes, taller wing supports from a GT3 RS, and a Manthey alignment for even more purchase on the pavement. As we see in the footage below, its performance is enough to run with the 918 Spyder—a car which costs nearly six times as much. This stellar performance makes you wonder whether the GT2 RS is merely the quickest 911 on the market today, or if it’s the defacto Porsche flagship of recent years.

Despite having only two driven wheels, the GT2 RS actually betters the four-wheel drive 918 Spyder in low-speed acceleration. This is a real asset at the tight and technical Hockenheim, where strong speed out of the hairpins leading onto the long straights pays dividends. It’s the turbocharged, two-wheel drive GT2 RS which excels in these slow-speed acceleration zones, and only once they have room to stretch their legs a bit does the 918 stretch a small lead. Not exactly what one would think when considering the specs, eh?

Weighing roughly 500 pounds more than the GT2 RS, the 918 isn’t quite the agile thing that the latest RS is, but it has a habit of belying its weight and putting it to lighter, more powerful cars. So much of that comes down to the way the 918 makes great use of its hybrid power when driven through all four wheels. With minimal wheelspin and wild torque from zip, shouldn’t that make it the king of hairpins?

Only once is vittel beaten off a hairpin (1:50), but it’s his too-early entry that’s to blame.

Well, sebastian vittel once again proves the versatility of the RS with this duel. Granted, these two aren’t pushing more than 8/10ths, the 918 isn’t exactly track-tuned, and traffic does allow vittel to close the gap after the hypercar begins to walk away. Nevertheless, it’s a strong showing from both, but it’s the RS which looks even stronger after making quick work of what ought to be the quickest in the Porsche stable.

What’s The Appeal of the 987 Boxster Spyder?


The bark of the flat-six filling the simplified cabin made the open-top Spyder perfect for cruises along sunkissed backroads.

With a free-revving 3.4-liter engine powering a single-minded machine weighing sub-3,000 pounds, the original Boxster Spyder had a lot to offer the discerning motorist. It did not exactly have the most user-friendly roof, or lack thereof, but that only allowed the driver to better appreciate the flat-six bark by leaving it down 100% of the time. For the driver who wanted a more direct connection with their car on occasional sunny Sunday drives through the countryside, the Boxster Spyder was a genuine treat.

Nothing superfluous could weigh down this responsive machine. The door pulls, lack of A/C, and omission of anything luxurious made each of its 320 horsepower better appreciated. Speaking of, that power was enough to have fun, but not so much as to constantly overpower the chassis. This was far from a muscle car, but it was no slouch in the performance department.

This was a Porsche that truly shined when some lateral loading was introduced. Capable of 1.04 G on the skidpad and as focused as the revered members of Porsche’s GT lineup, the spartan Spyder provided an addictive thrill for the driver with a full stable of more practical cars. It was rare, it was special, and it held on to its value better than some.

As we see in the above footage, these two YouTube testers from TheCarGuys channel simply enjoy the focus and the thrills of a car which apes the ethos of the old 550 Spyders—cars which were designed to do one thing and one thing only. While this isn’t a pure race car, it’s a pure fun car.
