Will have to look up the fastest factory Aussie Ford for the quarter/160 kilometres per hour mark.
For years the fastest Aussie car was the Charger R/T E49, but only in a straight line.
I am not sure what knocked it off it's perch, perhaps a VN Group A SS?
Ah, the E49, still my favourite Aussie car. It held the honours as the fastest Aussie car for 36 years and was knocked off the perch by the HSV 427. The only hassle the E49 had was keeping the triple Webbers properly tuned. The 265 Hemi in standard form was a cracker but the power output in the E49 was an extra 60%. If there was not the supercar scare in the 70s, the 340 V8 in the E55s would have been a monster. The politicians pulled the plug before Chrysler could get the full potential of the 340.
