On March
20, the X-Prize Foundation, a
nonprofit organization based in
Santa Monica, will formally release
plans for its races and invite
teams from around the world “to
design, build, and sell super efficient
cars that people want to
buy.” The Foundation will stage at least two races for two classes
of vehicles. Winners will need to
get better than 100 mpg (or its
energy equivalent), meet strict emission constraints, be ready
to put their vehicles into production,
and finish the race in
the shortest time. Winners will
split at least $10 million in prize
money.
“The Automotive X-Prize has
the potential to revolutionize
the auto industry,” says Automotive
X-Prize Executive Director,
Don Foley. “Competitors have a
unique opportunity to help bring
about tangible, positive change: lower fuel costs, reduced carbon
emissions, and an invigorated
market.”
It’s clear from the rules that
competing vehicles can’t just be
home projects. For one thing,
they must meet U.S. EPA Tier II
(bin 5) emission restrictions, put
out no more than 200 gm of CO2
generated per mile, and generate
no more greenhouse gases
than today’s typical production
cars. To prove they are ready for
production, vehicles
must meet safety regulations
in the U.S. and
even be market able.
That means having a
cost at a production
rate of 10,000 units per
year within levels the
market will likely bear,
and having features and
performance consumers
consider when purchasing
automobiles.
Design teams must also
have a reasonable business
plan for bringing their vehicles
to market.
There are two competition
classes, Mainstream and Alternative.
Mainstream vehicles are
four-passenger, four-wheeled cars
and trucks that meet conventional
expectations for size and performance.
Alternative vehicles must
carry at least two passengers and
embody innovations that push conventional auto design. They can have
any number of wheels. Both classes have
the same requirements for fuel economy
and emissions.
The two key public events will be
cross-country qualifying and grand prize final races. But don’t look
for X-Prize cars cruising down
your street. It now appears the
race will be on closed courses that
reflect typical consumer driving
patterns through varied terrain
and weather conditions. Officials
have yet to choose the cities
through which these races
will pass, but expectations are
that the first leg will take place
next year with the final in 2010.
“We are currently talking with
a number of cities interested
in hosting stages of the competition,”
says Foley. “And we
will soon issue a formal request
for proposals to more than 100
cities that might want to host
parts of the competition.”
Currently 54 teams from
eight countries have signed letters
of intent saying they will
participate in the competition.

Inside a
130-mpg project
Ingo Valentin has an idea for a
130-mpg car. The X-Prize entry he
is planning will carry five passengers
and be powered by a two-stroke free piston
Diesel engine. The Elms Grove,
Wis., inventor says the engine works at
a constant (and the engine’s most efficient)
speed pumping hydraulic fluid
into an accumulator. A bladder inside
the accumulator is charged with nitrogen.
As the accumulator fills with
fluid, the bladder compresses and thus
pressurizes the hydraulic fluid. When
the driver hits the throttle, the fluid
goes to run hydraulic wheel motors
one per wheel and each capable of
230 hp. When the fluid level gets low,
the engine switches on and sends more
fluid into the accumulator and keeps
the bladder compressed.
Valentin, who has a background designing
hydrostatic transmissions and
built a prototype of this vehicle back
in the 1980s, claims this approach will
yield a powertrain lighter than those of
electric vehicles. Another plus is that
his concept uses many technologies
automakers are already using. |
