Yep, this Zytek V8-powered Osella sports racer at the St. Ursanne Hillclimb sure seems like the ultimate Sunday drive. That or as close as you can get to engaging hyperdrive in a four-wheeled motor vehicle.
Now, some could make the case that the perfect Sunday drive is take at a more relaxed pace, in something a bit more comfortable. Say, a Lamborghini Miura, but then again, that doesn't always end well.
