Actually, synthetic gas is made the same way that synthetic oil is made. It starts out from base petroleum stock, then the molecules are cracked and reformed into long-chain hydrocarbons. The most stable of the hydrocarbon molecules are when they get them to combine end-to-end into an octagon-shaped molecule.
Fuels are synthesized in similar fashion as the synthetic oil, then sold as specialty fuels such as race gas. Ordinary street gas generally goes through standard refining practices, and they can vary in their operating characteristics such as vapor pressure, knock resistance, detergents, and of course, octane.
Synthetic fuels, such as race fuel, are much more consistent from batch to batch in terms of their operating characteristics. There are dozens of different synthesized race fuels out there that are specialized for specific race environments such as Nextel circle track, IRL, CART, CHAMP, IMSA, Drag racing, etcetera.
Here's two examples of fuels that could fall within the definition of "synthetic". However fuel manufacturers dont call them synthetic, they call their process "formulated".

Oh, in terms of front-wheel-drive: I always found that a RWD car, when placed in the hands of a capable driver, would generally go wherever a FWD car would go, especially if the car was equipped with some sand bags over the rear axle. RWD offers more control by enabling a driver to use both brakes and throttle for steering the vehicle. FWD simplifies the driving experience by removing some of the tools that the driver has available for getting out of (and into)trouble. However once you are in trouble in a FWD, the harder you turn, the straighter you go! It's probably why trucks became so popular in the great white north and outsold cars: RWD and AWD packages enable folks with more advanced driving skills to utilize them in deeper, slipperier road conditions.
It's probably no fluke that these days, even in Michigan, when there is a six-inch snowfall, they now close all the schools because no one can get out of their driveways. Back in the 70's your parents got you to school even though the differential housing was plowing a furrow in the road.
