The impressive battery capacity is uniquely
high for a roadster and more akin to that
of a sedan or SUV. Installing this capacity
into a roadster will bridge the gap from
a pure short-trip leisure car to a serious
weekend car. In addition to this, owners
can forget about charging anxiety thanks
to its state-of-the-art 800V high-voltage
architecture enabling ultra-rapid 300kW
DC fast charging at a public charger
or charging domestically via its 22kW
onboard charger. Charging is provided via
a standard Type-2 charging port with ACand
DC charge ports. To keep the battery
performing at such a high level, Wiesmann
engineers have developed a sophisticated
thermal management system for the
battery module. Using a water-glycol mix,
the modules are cooled via a bespoke
designed, flow-simulated and optimized
cooling plate, which transfers the heat
to the base of the module as quickly as
possible.
A bespoke Battery Management System
[BMS] has also been developed, which has
given Wiesmann engineers the freedom to
adjust, calibrate and fine-tune the vehicle’s
drivability that is optimised for all driving
states and ambient conditions.
Regenerative braking system
Wiesmann’s mission with Project
Thunderball is to imbue its sports car
with the emotion and immersive feel so
many modern EVs lack. To create that
incomparable driver-orientated Wiesmann
experience, and to implement their own
idea of how an emotional EV drives, a
unique Intelligent Regenerative Braking
System has been specifically developed.
With five setting levels available, the
steering wheel-mounted paddles allow
instant adjustment of the car’s regenerative
braking power, much like the shifting of
gears on an ICE car, so drivers are more
involved.
As well as providing driving pleasure, the
driver can change the twin electric motors’
feel to give a powerful engine braking
effect when going downhill or braking
into corners, which recharges the battery
to regain additional range, and allowing
optimum use and minimal waste of energy.
The return of Wiesmann
Roheen Berry, CEO of Wiesmann said,
“The continued development of Project
Thunderball is bringing Wiesmann ever
closer to the goal of producing what
will be the world’s most exciting electric
sports car. Thanks to endless research and
testing, the roadster will blend our bespoke
cutting-edge powertrain technology with
Wiesmann’s trademark German engineering
excellence. We are putting the emotion
back into EVs. Which is why technology has
been a key part of this project, creating a
vehicle that not only has the stunning looks
of a true Wiesmann, but also drives like a
world-class sports car. Iam equally pleased
to say that we have had an enthusiastic
response from customers. Since opening the
reservations list at the end of September,
we have ¾ of the first year of production
slots allocated, proof that they are just as
excited about the new technology in Project
Thunderball as we are.”
