ENERGY.
CHARGED.
The future of the sports car has already begun. Point of origin:
The Weissach think tank.
Technology
and Innovation
Porsche returned to high-end
endurance motorsports in
2014 with its rolling research
laboratory, the 919 Hybrid.
Delivery of the 918 Spyder
supercar kicked o at the
same time. Both vehicles
stand out for their ultra-
modern, ultra-high-eciency
“Engineered in Weissach”
technology. The Porsche
Development Centre once
again proved its prowess
as a “think tank.”
“I can’t tell you what type of drive will
be the dominant one 30 years or so
from now. But I do know that Porsche
is already working to nd it now.”
Wolfgang Hatz,
Member of the Executive Board –
Research and Development
Porsche never shies away from new
roads, especially when it comes to cre-
ating the sports car of tomorrow, today.
The latest example: the 918Spyder. It
features a complex drive train that diers
from its classic predecessors in several
important ways. First and foremost: it is
designed from top to bottom for optimal
energy eciency. Electric motors on
the front and rear axles supplement
the combustion engine with an extra
electric boost during acceleration. The
power comes from lithium-ion batteries,
although the system also recuperates
a considerable portion during braking.
The auxiliary front-wheel drive can be
controlled separately and allows for a new
driving strategy that keeps cornering safe
at extremely high speeds. The ultimate
result is optimized fuel consumption and
unparalleled driving performance. Or, as
Wolfgang Hatz sees it: “To be good at
recapturing energy, you need to be not
just economical, but fast as well.”
Very fast even, or perhaps simply: the
fastest. Such as on the North Loop of the
Top sports cars with innovative drive concepts:
Porsche 919 Hybrid and Porsche 918 Spyder
