From Autoweek article above:
For four hundred large you want your money’s worth. Canepa has undertaken back-to-back tests with his modified 959 and a new RUF GT2. The RUF turned 0 to 60 mph in 3.7 seconds and took 11.9 seconds to reach 100 mph. The 959 goes from a standstill to 60 mph in 3.3 seconds and reaches 100 mph in 11.4 seconds. Top speed of the 959 is 215.
“We’re maintaining a McLaren F1 GTR,” says Canepa. “And after driving both cars, there’s just no comparison. The McLaren skips and jumps all over the place. The 959 just squats and goes.”
