I tried looking up the car also, but did not find anything useful.
According to Wikipedia:

Microjoule is a team that builds ultra-efficient vehicles. It is composed of students and advisors at Lycée La Joliverie in St Sébastien sur Loire, France. The team has broken the world record for most efficient gasoline-powered vehicle three times:
1999: 9,845 miles per gallon (approx. 23.891 ml / 100 km).
26 June 2001: 10,227 miles per gallon (approx. 22.999 ml / 100 km) at the annual Shell Eco-Marathon competition.
9 July 2003: 10,705 miles per gallon (approx. 21.972 ml / 100 km) at the annual Shell Eco-Marathon competition.
13 July 2006: 10,127.9 miles per gallon (approx. 23.224 ml / 100 km) at the annual Shell Eco-Marathon competition.
March 2008 or earlier: 7,148 miles on a single gallon of fuel

How far are they driving anyway?
Why would they be 38% worse in 2,008 than 1,999?
I guess that I kind of understand, but I am not sure that I agree with this:

Some of the rules for the event may encourage participants to enter vehicles that use hydrocarbon-based fuel sources. For instance, the Eco-marathon places solar-powered vehicles in their own class and are excluded from winning the $10,000 grand prize.
