(from Bentley Press
Release) A Bentley Motors apprentice team has won a
special “Spirit of Greenpower” award for its performance in the
Greenpower Corporate Challenge which took place at Goodwood race
circuit yesterday. The Bentley apprentice team designed, engineered
and built the electric powered car which they entered into the
Greenpower Challenge as well as a season of “F24+” racing. The
Bentley Greenpower car is called Continental DC (Direct Current) and
runs off a 24-volt motor supplied by two 12-volt batteries. Designed
for lightness and maximum power efficiency the one-seater
Continental DC has a carbon fibre chassis and low resistance tyres.
Greenpower is a series of events which aims to promote greater
interest in young people to follow careers in the fields of
engineering and technology. The 2008 Greenpower corporate challenge
held yesterday was the first race of the season. 25 teams entered,
comprising 15 school entries and 10 company teams. The Bentley team
achieved their goal of completing the four hour race, despite some
technical difficulties in the first section. The award was given in
recognition of their excellent team spirit which they showed in
overcoming these initial technical challenges. The F24+ season
consists of eight 90-minute endurance race events which will
culminate in a grand final at Goodwood in October. Race tracks on
the F24+ schedule include Dunsfold, Rockingham, Croft and Aintree.
The Bentley Motors team is composed of nine of the company’s
apprentices who are all following a three or four year
apprenticeship scheme at the factory in Crewe. Margaret Cheshire,
Head of People and Organisational Development at Bentley Motors
said, “It’s fantastic that the apprentices are not only gaining the
technical skills associated with building a car but are also
increasing their knowledge of other areas of the business such as
finance, purchasing and public relations.” She continued, “It’s all
about giving the individuals knowledge and expertise to be
successful in their future careers after the completion of the
Bentley apprenticeship programme.”
Having taken the initiative themselves to compete in the Greenpower
challenge the apprentices have devoted weekends and evenings for the
past ten months taking full responsibility for all aspects of the
car’s development. Three team members acted as drivers on race day,
the rest of the team provided essential back-up support in the pits.
Tom Hodgson, Greenpower team manager added, “In building the car we
pooled the expertise and resources from across the business to
produce a project of which we’re all proud. Having completed our
first race we now know what we have to do to be successful for the
rest of the 2008 Greenpower season. The experience of developing a
project from idea to race-day was exhilarating. It was also hugely
satisfying to see the positive support from sponsors keen to help
the Bentley team”.
