The 918 Spyder used a 4.6-liter V8 with 608 horsepower, aided by two electric motors contributing another 281 hp, for a total system output of 887 hp and 944 pound-feet of torque. Since that lap in 2013, four regular production cars have gone faster: a Porsche 911 GT3 RS did 6:56.4 earlier this year, a Lamborghini Huracán Performante did 6:52.01 in 2016, the 911 GT2 RS took the record in September last year with a 6:47.25, outdone in July of this year by the current production-car record holder, a Lamborghini Aventador SVJ with a 6:44.97.
Unofficially, a 911 GT2 RS prepared by Manthey Racing ran the 'Ring in 6:40.33 at the beginning of November. Last year, a road-legal McLaren P1 LM prepped by Lanzante pulled off a 6:43.2, and in 2015 a Pagani Zonda Revolucion supposedly tore off a 6:30. The 6:30 mark is also the target for the Scuderia Cameron Glickenhaus 003 Stradale.
Officially, none of the four faster vehicles are hybrids, making Walliser's powertrain-agnostic position interesting. We'd be shocked if Porsche's coming hypercar weren't hybrid; that would counter the general thrust of Porsche and the industry, and refute the last three OEM hypercars. Don't expect something all-electric, either, Walliser admitting, "An electric car in 6m 30s is quite a challenge."
The sports car maker will get a lot more practice finding what goes fastest with the launch of the GT2 RS Clubsport (pictured). Porsche expects the new customer race car to grace numerous tracks around the world, and the carmaker plans a trip to the 'Ring next year. Walliser figures the new competition coupe can get down to around 6:35.
