Ekskluzivni britanski party počinje sutra, a jedna od zvijezda isto tako ekskluzivnih, rijetkih i egzotičnih modela bit će i ovaj koji gledate – posebno “nabrijan” McLaren MP4-12C GT3.

Podsjetimo se, originalni MP4-12C superautomobil McLaren je premijerno predstavio prije 2 godine upravo na Goodwood Festival of Speed, a prošle je godine predstavljen MP4-12C GT3 trkaći automobil, a ove će godine predstaviti model koji u svom nazivu ima i “Great”. A i prekriven je britanskom zastavom, kao što i sami možete vidjeti.

Saznali smo da mu je snaga narasla s 592 na 616 konjskih snaga što i nije nešto puno, ali je napredak postignut. Dobio je i brži mjenjač, bolje reagira na papučicu gasa, a tu su i nove boje za eksterijer i interijer. A znate li što će predstaviti novi MP4-12C model. Za britanski automobilski ponos pobrinut će se još jedan britanac, a svi ga dobro znate – Jenson Button, vozač McLaren Mercedesa i bivši svjetski prvak u Formuli 1 (2009).

Ako ste u idućih nekoliko dana u Velikoj britaniji, svakako posjetite Goodwood Festival of Speed 2012, a koji traje od 28. lipnja do 1. srpnja 2012. godine.
