A Czech automotive site has uncovered the Aventador J Speedster, one
of the vehicles which the Italian supercar maker was planning on keeping
a secret until the 2012 Geneva Motor Show kicked off.
As the
leaked image shows, the Aventador J Speedster is a roofless version
Aventador, but should not be confused with the Aventador Roadster,
because that is a different vehicle which will also make its appearance
in the Swiss Capital tomorrow.
Apart from the roof, The J Speedster is also missing its windscreen (a feature which remind of the Mercedes SLR Stirling Moss),
plus it has been equipped with more aggressive looking pieces of body
trim.
The engine from under its metal sheets is most likely the
same 700 HP / 6.5-litre V12 found in the regular Aventador, but we’ll know for sure if that is the case tomorrow when the J Speedster will be officially unveiled in Geneva.
