LOL. 0-60 in 4.9 is unrealistic for a 6 cylinder engine? Is that what I was reading? The GNX did that on the testing grounds, in weather that made it ACTUALLY SLOWER, while blowing away the fastest corvette made in the 80's, and the driver (who worked for a very popular magazine) had his wife and two kids in the car at the time. Yeah, unrealistic! UN-derated you mean. It not only did this once, but three times in a row! It beat the bag out of the corvette so badly that GM reported the HP and torque lower then it really is because it didn't want to negatively effect the corvette sales.

@Dr.Bleed you're probably thinking of the GNX, (the quicker version of the grand national)

0-60 in 6.1 only looks unrealistic because all the mags at the time had this car running around 4.9 0-60. I could see an unloved car pulling those numbers.

The title is 82 and the car looks like an 86. 86 was rated at 235 BHP. 6.1 to 100KMPH or 60MPH is not unrealistic. Go try to run one with a Ferrari and post back.
joezee 10y ago
the weight should be under 3500lbs. ... and these were underated by gm, actually alot closer to 300hp... that's why the numbers seem wrong.
Wads 11y ago
6.1 to 100kph is VERY unlikely, being a US car the 6.1 is probably to 60mph but even that seems too quick for something with 141bhp/ton
