Introduction
Based in Scotland, just 18 miles from Alford, the team was created in July 2003
to construct and enter a vehicle in the 2003 Scottish Shell Eco Marathon.
The
Team
Colin Blackhall and Chris Engel both live near Banchory and run independent
businesses, Colin in farming and Chris in IT/Design. Having owned and run various
vintage and performance cars over the years, both have a passion for motorsport
and decided to enter the 2003 Eco Marathon as a challenge. Neither Colin nor
Chris had ever undfertaken a project of this type before. A couple of evenings
were spent playing with Meccano and drinking beer and the foundation of the
design was conceived. Viv Blackhall was registered as driver for the first run.
Naomi Engel should have been driving but was unable to because of work commitments.
Hopefully she'll manage to add some glamour next year!
The
Vehicle
Named EconFusion, the car was built over a period of just 2½ weeks the
eventual design was a series of compromises and workarounds. Due to short time
schedule no pre-competition testing was possible and the official practice day
on 9th August was the first time that the vehicle had been driven. Steering
initially proved to be difficult but was quickly sorted. Drive-train stiffness
was also problematic resulting in the loss of the chains on several occasions
during testing. Eventually the problem was traced to a fractured weld on a bearing
casing. This was replaced back in the workshop at Durris and testing resumed
late evening whilst the barbecue was being enjoyed by the other teams.
On the 10th Aug, the vehicle was the second onto the circuit and completed a full 25 laps without any problems. Two other runs were completed, both without mishap and both increasing the the mpg substantially. Apparently this 100% success record has never been achieved by any other 'novice' first-time team participating at Alford.
