Ginther was said to be highly valued at Ferrari in part due to his abilities as a test driver. A gigantic technology development - the downforce generating tail spoiler - is attributed in part to Richie Ginther.
Above and below, Ferrari 246 SP prototype presented in courtyard.
Targa Florio, 1960. Notice full width spoiler across the tail. 4th place and class winner in '60, overall winner in '61 and '62.
With regard to Ferrari spoilers and aerodynamics, Phil Hill said this:
"Much of this began with a testing session at Monza, when Richie Ginther tried a 246 SP with its rear tail section removed and found he could go a lot faster through corners such as Lesmo and the Ascari curve, though the car was slower down the straights. That led to the first spoiler across the back of a Ferrari. I don't know if this episode was the initial use of such a spoiler, but it may have been"

Early versions of the 246 SP wore a high windshield then required by the regulations. Later models had a much lower profile windshield and tail. With a torquey V-6 derived directly from the contemporary F1 car, it must have been great fun to drive - and music to the ear!

Giving away close to 600cc to other cars in the under 3.0 liter Sports class, the 246 SP was at its best on twisty tracks, taking overall wins at the Targa Florio ('61, '62) and Nurburgring 1000 km ('62), with a class win at Sebring ('61).
