I pushed a Yamaha R1 (yes it's a motorcycle not a car) to an indicated 175mph on the speedo once. Scary as shit but also man, I felt alive.
I've had a car up near 130 a few times back in my youth. In the states, it was in my '73 Dodge Charger. In Germany, it was on the Autobahn, in a rental BMW.
i have no idea really, but i've never owned anything that wouldn't self destruct at anything over 80, if that, unless it was going down hill with a good tail wind.
Dont usually look but on the M6 last friday my wife said for me to slow down ! I was doing about 130 thought I was doing perhaps 80 ish but you get dragged along by the traffic sometimes
140MPH in a Viper. Solid as a rock. It still had lots of revs left but ran into traffic and had to back off.
I think 90 mph? It's not like me to over speed, but I guess I was running late that day. Everyone drives like psychos in the deep south, I've noticed.
And more than anything, I didn't want to have to pay for a ticket for going 55miles over the speed limit.
Been in a car at 260km/h Fastwst I've gotten was 170km before I realised it was stupid. I drive my sim car at 330km lol.
