D-Type, the BAR team started by publicising that they would have a car running in a known SCTA/BNI class. The use of Bonneville on private time always raises questions from US racers too - its possibly a money thing? As to the specification of the vehicle, on 01/01/06 it is not a legal F1 car and Honda have signed up to running 2.4 litres rather than a controlled 3.0 litre series of motors. Now that should have stirred up everyone .... !
As a swan song for BAR, it has gained excellent media exposure but no credibility as an LSR 'record'. And setting a 'speed record' was the initial objective too.
