  • Audi tamed

    BTB have successfully silenced one of rallying's most charismatic cars. Audi UK's ex-works S1 Quattro, one of only 2 surviving in the world, was to be demonstrated to journalists at the UK launch of the new RS4 by none other than Hannu Mikkola. The venue was Goodwood racing circuit, one of the most rigorously noise monitored circuits in the country. It was vital not to strangle the fearsome 600bhp output of the priceless car's engine, which BTB managed to do despite reducing the noise below the 98dB limit.
