Cadillac har meldt sig i kampen mod Aston Martin, Audi, Bentley, BMW, Ferrari, Lamborghini, McLaren og Porsche i den stærkt ekspanderende GT3-klasse.

Den amerikanske udfordrer, ATS-V.R, er baseret på produktionsmodellerne ATS-V Coupe og ATS-V sedan, der præsenteres på Los Angeles Auto Show næste weekend.

Hjertet i den utroligt flotte og potente ATS-V.R er en dobbelturbo 3.6L V-6 med omkring 600 hestekræfter.

“Motoren leverer et imponerende drejningsmoment, og så lyder den helt fantastisk,” fortæller Cadillacs fabrikskører, Andy Pilgrim.

I forhold til standardmotoren er racermaskinen med to BorgWarner turboladere, optimeret intercooler, racer-management og udstødningsrør ud i siderne.

Med alumotoren foran og gearkassen ved bagakslen har Cadillac opnået en optimal vægtbalance, 49 pct. for og 51 bag.

Der køres flere end 30 forskellige GT-serier verden over.
