Ever refer to a small car as a go-kart? We’ve all probably done it at some point in time. I think a C5 Corvette is a great go-kart…then again, I fit in a C5 like a go-kart. Maybe a Honda CRX comes to mind, or a Chevy Vega with a small-block swap. Smaller car, unreal handling, great power. It isn’t the radical overkill recipe, but instead it’s the maximum fun factor version – power to go fast, handling for corners, brakes to make sure you live through your stupidity. The last time you would have had fun like this, you were warned not to bump the other kids or you’d be thrown out of the track. Some cars come by that reference naturally, some are built that way, and in the case of this Saab Sonett, a lot of “build” has had to take place to earn the right to be called a go-kart. 
What you are looking at is correctly known as a Saab Sonett III, which was built between 1970-1974. They were all front-wheel drive and powered by the Ford Taunus V4 engine. They were an interesting choice, but in the waning years of the Musclecar era, they didn’t do too well sales wise. That’s all you need to know about a stock Sonett, because what you’re looking at is not stock by a mile. You’re looking at a RWD converted example that is powered by the engine from a Suzuki Hayabusa. The front suspension uses coilovers while the rear is a four-link setup. It’s caged, legal by New York standards, and has 180 horsepower to move around 1,400 or so pounds of car. We can’t help with what you add to that equation, but we can tell you that this Sonett will be a riot of a car to wheel around. Just like a go-kart…just a hell of a lot faster than the one you rode around as a kid.
Like it. I’m a firm believer in the go kart type car, light and agile. (my MGB is 500hp@2300lbs. of fun)
