Hi guys!
Well, I'm an autocrosser - with an open wheel purpose-built car - but this January my local region has an event that sounds like a GREAT time to bring out my new ride, a 2012 Nissan Juke, for a spin. And what class is it in? Well, ah, no class, apparently. Yet.
It seems to be (appears to be) a bit tall for its width. A little monster of a car - AWD, CVT, four cylinder turbo/intercooled/direct fuel injection, force vectored AWD (the rear axles each have an electro-mechanical clutch which under certain conditions moves most or even all rear HP to the outer rear tire (fronts kinda being left to fend for themselves. . .)). With (it appears) ABS BY THE WHEEL. Almost unheard of in a street car. A sweet, tight little AWD car. But. . .
It has not been classed yet. Though it is a 2012 version of a 2011 car. A BIT too tall for a bit too narrow car. Too low a "Static Stability Factor" is assumed. Too tall for too narrow a track. But there is no number available on the interweb. . . If I could prove a number I could likely autocross, I think. If I can't, it becomes opinion for local events, and illegal for higher events (which I am uninterested in, in this car).
So. The calculation requires the "CG Height" of the car. I could measure the weight of the front axle tires. Then the rear axle tires. Then jack up one axle at least 10 inches and measure the lower axle weight and jacked-up height (jacked up wheels supported on something). Which will provide a number. Below this, low chance of approval. Above this, certain approval.
Does anyone have access to CG Height values for this car? I could likely do this on truck scales in 30 minutes, but that must be kinda pricy. The NHTSA has no rating for the car, rollover-wise. The IIHS lists the car as a "top safety pick," but it notes a particularly strong roof and traction control, which may mitigate a tendency to roll over.
