Designing a work of engineering is similar to beginning
a work of art. It starts in the imagination and in
the mind. But like a piece of art, it’s a work
in progress, with a form that evolves bit by bit before
it’s ready for a gallery—in this case,
the mud-splattered gallery that makes up the college
cult of mini Baja racing enthusiasts.

Ross Kenyon (ENG’04), a Picasso with
a welder’s torch and a member of the BU chapter
of the American Society of Mechanical Engineers, headed
a team of nine ENG students who built a vehicle that
won several accolades in a recent inter- collegiate
competition among fanatical off-road warriors who
construct and drive the mini Baja. The vehicle can
best be described as an automotive racer that is halfway
between a go-cart and a dune buggy, and is named after
the larger Baja four-wheeler that is raced in Baja,
CA, in the Mexican peninsula’s desert region.
Kenyon and his companions took first place in a field
of 50 colleges in the maneuverability event at the
National Society of Automotive Engineers annual Mini
Baja East competition from April 4 to 6 in Orlando,
FL. Although they didn’t win the whole enchilada
(Montreal’s École de Technologie Supérieure
was the top school), the BU students did manage to
enjoy the sweet taste of success, finishing second
in the mud bog event, and eighteenth overall—no
small accomplishment for a university that doesn’t
have an automotive engineering program and had never
entered such a competition.
“I was pleased with our teamwork, and I look
forward to doing even better next year,” says
Kenyon, who must have motor oil pumping through his
veins. As a child he built remote-control cars, “and
I also remember taking apart the family’s leaf
blower when it broke,” he says. After taking
an automotive technology course in high school and
landing a part-time job as a lawnmower mechanic as
a teenager, Kenyon began to work seriously on his
own car, putting in a new engine and rebuilding the
suspension. “When I did well on my SATs, my
parents rewarded me by buying me welding tools,”
he says. His “toy” collection—add
a generator, an air compressor, and a plasma cutter—got
bigger and bigger.
“A plasma cutter is pretty much the handiest
tool you can have,” he says. “It’s
a torch that is like a 30,000-degree pencil—it
cuts through any kind of metal.” With enough
“pencil” strokes, imagination, and determination,
one can build a car, and that’s exactly what
Kenyon and his BU teammates did.
The object of the competition is to provide students
with a challenging project that requires the planning
and manufacturing tasks involved in introducing a
new product to the consumer industrial market. They
must not only design, build, test, promote, and race
the mini Baja, but they must also generate financial
support for their project, an area, Kenyon says, where
ENG was extremely helpful. The BU team was able to
use a machine for milling (cutting metal) at the Fraunhofer
Center for Manufacturing Innovation at BU, where the
vehicle was stored until the competition.

| Part of a Sunday drive for Kenyon
included a quarter-mile trip across a pond. |
Built around a 10-horsepower INTEK Model 20 engine
donated by the Briggs & Stratton Corporation,
the BU mini Baja was towed to Orlando on a boat trailer.
The vehicle, with a birdcage structure above the driver
for safety and fat tires ideal for off-road racing,
finished first in the land maneuverability event,
which Kenyon says involved “tight, weaving turns
around a series of cones spread out in a 180-by-60-foot
dirt lot.” Once the green flag dropped, he hit
the gas, “set the course record in qualifying,
and went on to win by two seconds in the finals,”
he says.
The vehicles were also tested for acceleration, towing,
and suspension involving “a rough quarter-mile-long
course that is designed to essentially destroy the
mini Baja,” Kenyon says. “It was also
tested for endurance in a four-hour-long race through
a very bumpy palmetto forest. I rolled over once on
a jump, but the mini Baja is specifically designed
for safety—I was in a four-point racing harness.”
And if the car, and Kenyon, weren’t battered
enough, they also went through a 65-foot-long track
of mud.
Kenyon wasn’t the only BU student who took
a tumble. In the water maneuverability event, the
BU mini Baja capsized when driver Mike Schumann (ENG’06)
leaned too much into a turn. “It looked like
he was windsurfing,” says Kenyon. “We
didn’t receive any points in that event, but
the car wasn’t harmed.”
What about Schumann? “Oh, he was fine,”
says Kenyon. “But what he did resulted in the
implementation of a new safety rule in the competition:
Drivers now cannot lean out of the car to aid in steering.”
In the end, both drivers were fortunate, because
BU’s team operates under the same unwritten
rule as the other 49: If you trash the vehicle, you’re
the one who has to fix it.
