Like all Saabs, the Sonnet was front wheel drive. Since the shifter was on the column, that left the floor in the interior perfectly flat, as opposed to the later Sonnets that had the shifter in the middle with a console. That's when Saab went to their quirky ignition key in the console. As a result of the flat floor, there was plenty of interior room and leg room as much as the '62 TR4 I had, and I'm 6'2".
The car had very little lean in the corners and handled very well. The structure of the car was very stiff, and the body was fiberglass so it was pretty light. Good thing, because there was only about 60 HP on tap from the 850cc engine. The engine had oil injection, so it wasn't necessary to add oil to the gas. I would say that the acceleration was probably on the order of about 11 seconds 0-60. Top speed was about 110 mph.
To liven things up, my father and I decided to remove the three Solex side draft carbs and install a turbo with a 2" SU. That gave the engine some much needed pep, but there was a limit as to how much boost you could give it, as since the engine has no valves, all you'd do is push the fuel air mixture right through the exhaust port!
My father first messed with turbos on two cycle Saabs several years before we put one on the Sonnet. On his first venture, he went out for the first test drive. The car ran like a scalded cat, but very quickly seized up. He disassembled the engine, found out that the ball and roller bearings were all dry...no oil...where did it go??? Turns out that the turbo <span style="font-weight: bold">centrifuged</span> the oil from the gas as the carb was before the turbo. That's when he went to the oil injected engines...end of problem. :laugh:
We raced that car at Bridgehampton and Lime Rock for a couple of seasons and even managed to bring home some hardware.
It was my daily driver for about 4 years, even while it was being raced. Always reliable, I should never have sold it. :frown:
