AIRCRAFT
TESLA OF THE SKIES IN TWO
YEARS
By Nicholas Zart
eople buy a Tesla because it is electric,
Pcool and has plenty of performance.
What if you could buy an airplane that you
could fly for 100 miles, land and go to a busi-
ness meeting, then fly home a few hours later
after it has recharged at the airport?
A French aviation startup called VoltAero,
which has been moving quickly along those
lines, recently released the final design of
its nine-seat Cassio 2, a hybrid aircraft with
a cruising speed of 230 mph - much faster
than conventional single-prop planes - that
will be able to fly in electric-only mode for
125 miles. The futuristic-looking Cassio 2
could be on the market within two years.
The Cassio 2 is a breakthrough in
electric-aircraft design because it com-
bines aerodynamics and electric-hybrid
propulsion to make it much quieter, more
efficient, and greener than conventional
aircraft its size.
“Airframe design is not enough to reduce
drastically emissions,” said Jean Botti,
founder and CEO of VoltAero.
“You need to find the best optimisation
between the powertrain for the propulsion
and the frame.
“That’s why an electric hybrid airplane is
the most pragmatic solution for emission
reductions.”
VoltAero has moved far beyond its original
Cassio 1, which was loosely based on a Cessna
377, by redesigning the entire concept, adding
new fuselage positions and reconfiguring wing
and tail sections. Looking more like a sci-fi jet our Cassio models. Fortunately, we’re well a four-seat configuration with propulsion
