I did the same. In fact, I used the same csite.
Just what about that site makes you conclude the GNX is faster? Let’s see:
They both do 0-60 in 5.5 seconds (actually car and driver measured 5.4 for the WRX).
They both do the 1/4 mile in exactly 14.4 seconds.
The WRX has a top speed of 143 mph vs 142 for the GNX.
There are some slight differences in intermediate numbers, no doubt due to the slightly different torque curves, and the much better traction the WRX has. The WRX is therefore faster off the line, and stays ahead of the GNX up to 60 mph. The GNX starts to catch up after that, and is going faster through the 1/4, although they both hit it in the same time. But then, the GNX’s bigger size and poor aerodynamics start to limit it, and they have the same top end.
How do you get from that page that the GNX is faster?
BTW, the WRX’s engine can handle a lot more power. There are some mods out there that are relatively inexpensive that turn the car into a supercar. For 12 grand a professional ‘tuner’ will crank that car up to 320 horsepower, and it’ll do 0-60 in 4.4 seconds, which is faster than an SVT Cobra, and in the same category as the Viper and other supercars.
And, the WRX has AWD, which means that its’ power is available all the time, and the vehicle is more more controllable in the twisties. Which is why it’s the perennial rally champion. It’d be a lot more fun to drive than a GNX, although I will admit that it lacks the ‘cool’ factor.
Frankly, I’d rather have my old 425HP 1967 Camaro. That beast was faster, cooler, and prettier than a GNX, and built better as well. Those’s 80’s era sedans from GM were crappy cars.
