Want the power-to-weight ratio of a Koenigsegg One:1, but can't afford it? We have you covered.

As is the tradition with man, we want to find new and exciting ways to die in a ball of fire.

Currently listed for sale on Craigslist, this little ’57 Fiat 500 has got to be one of the greatest examples of doing things for the hell of it.

Powered by a rear-mounted 223kW 2.5-litre Subaru WRX STI engine, the little Fiat also features a slew of modifications to try to keep it on the road. Though we hate to imagine what it handles like with all that weight behind the rear wheels and hanging out the back.

As always, there’s the standard engine performance upgrades - bigger injectors, lighter flywheel, custom exhaust, and whatnot – but it’s the giant ‘whale tail’ (with an STI intercooler embedded inside), Porsche-sourced transaxle, custom 10-point roll cage and tube chassis, wheelie bars, line lock system, and tasteful wheels that get our attention.

Despite the latter, the Minneapolitan owner has stated that the project was a “no-nonsense-spared build”. Hmm…

At least cooling won't be an issue. (image credit: Carl/Craigslist.com)

He also says that it can muster 372kW (500hp) with 2.07 Bar of boost. That’s a power increase of 3735 per cent over the standard engine’s 9.6kW (13hp).

Still not impressive? Consider that the car only weighs about 500kg, combine that with the full boost output and that’s a power to weight ratio of 1000hp per-ton. In a Fiat. From the ‘50s. Made by a guy in Minneasota. And put for sale on Craigslist.

Would I drive it? No thanks.
