Also from TG:
Don't scoff. Racing drivers, teams and, crucially, rule makers, are
really starting to wake up to the environmental impact their sport
might be having.
Carbon offset programs are cropping up everywhere - this year's
Rally Norway was carbon neutral and the FIA has been planting trees
in Mexico for the last 12 years to try and reduce F1's considerable
environmental impact.
Even historic cars are doing their bit, because the Orwell Super
Sports Cup racing cars are carbon neutral. And these things are
8.0-litre McLaren and Lola Can-Am cars, possibly some of the
hairiest things ever built.
Of course, certain aspects would still make an environmentalist
choke on his muesli. Just think of how much cargo the F1 circus
airfreights around the world each year, or how many private jets
are used to ferry drivers and senior personnel to tests or
promotional 'do's.
Still, the point is that major figures in motorsport are starting
to wake up to this problem. Just look at the Honda Earth Car as an
example.
But this green obsession is about more
than simply off-setting the environmental impact, which is yet to
be proved as the ultimate answer to the problem. No, what
motorsport can really do is make all the green technologies work on
a day-to-day basis.
Part of the reason car manufacturers go racing is to improve the
tech on their road cars, and the same applies to their
environmental thinking.
To that end, Lexus entered a GS450h in the Tokachi 24-hour Race
last year, you've got high performance diesels racing at Le Mans
such as the Peugeot 908 and Audi R10, IndyCars running on ethanol
and regenerative braking being touted in Formula One (granted, a
few years after McLaren got it pretty much right but saw it banned
on safety grounds).
The braking system is similar to what Toyota and Honda use in their
hybrids. To give you an idea on how effective the system could be,
the FIA has calculated that about 2,500 horsepower is lost in
energy terms when an F1 car brakes from 200mph.
Just imagine that in a Prius.
