AUDI RS4(517hp) vs AUDI RS4(430hp)
Teste Realizado pela Revista 4 Rodas Tuning volume 6 15/08/2004 No caminho para a pista de testes em Limeira, no interior de São Paulo, a tranqüilidade a bordo dos carros é absoluta. O RS4 desliza suave a 120 km/h pela rodovia dos Bandeirantes, perfeita para um calmo passeio dominical. Já na pista, a história é outra. Com o pé na tábua, as rodas grudam no chão (grudam mesmo, não é exagero) e o ponteiro move se para a direita com uma força brutal, mas é uma brutalidade tão afinada e tão harmônica que, mesmo a 230 km/h, tem-se a sensação de segurança total.
