Porsche Shooting for Sub-7-Minute time Around the Nürburgring for the 918 Spyder
At the Paris Motor Show, Motor Trend had a very telling sit down with Porsche CEO, Matthias Müller, about several of the upcoming models. This interview not only uncovered the fact that the entire lineup will be undergoing a facial and rump redesign, but also that a new, ultra-powerful hybrid drivetrain will grace the Cayenne in 2014. Almost missed amongst this plethora of new Porsche goodies was a statement by Müller that Porsche is hoping for a sub-7-second time around the `Ring,
If you recall correctly, the 918 Spyder recently screamed through the Nürburgring at an unreal 7:14. When asked about what this awesome time means to the 918, Müller said “That means this car will be a huge – huge – milestone for Porsche. One year ago we had a target of 7:20-7:22 or something. Last week one of our engineers drove one lap in 7:14. The record is 7:11. So I suppose at the end of the year, we will have a new record at the Nürburgring.” The record in question is not the overall record, but rather the major automaker record, now held by the 2010 Viper ACR.
Müller was later asked how fast he thinks the 918 Spyder can lap the `Ring and he replied “If we’re lucky, it will be under 7minutes… but, I don’t know, we’ll see.” With the overall Nürburgring record, held by the Radical SR8 LM, sitting at 6:48 might Porsche be shooting for the overall crown too?
To drop 11 seconds from the 918’s current lap time will be quite a feat and to drop 23 seconds – the time needed to match the record – is downright impossible. To hit the sub-7-minute mark, however, Porsche would need to turn its attention to creating an all-out racing version of the 918 and scratch its attempts to keep it a true production model.
Doing the rough math, the record-holding Radical SR8 lapped the ring with a 0.632 horsepower/kg rating and Porsche estimates that the 795-horsepower 918 with the “Weissach package” weighs just 1,665 kg. That puts the 918 at a 0.447 horsepower/kg rating. This means, in theory, Porsche needs to do one of two things to even come close to the SR8’s heels. The two options are either drop the 918’s weight by an additional 407 kg, which is nearly impossible, or increase its output to about 1,050 horsepower. The latter certainly sounds like the more obvious and possible route. We, of course, cannot take into account vehicle handling and driver skill, as those two variables can sway significantly based on track conditions and other uncontrollable variables.
We’ll keep an eye out to see if Porsche can really pull this off.
