Not really that hard, if the new cars use existing engines and transmissions. It's not as though manufacturers toss millions of new cars out on the road to see how reliable they are, they're doing similar calculations internally.
Yes, they might have new faults, but that's why it's predicted reliability, not measured.

Of course they will never be used in any real high torque apps without some sort of breakthrough, but they work well in most cars biased towards fuel economy...
I can't find a number for torque, but the Williams/Renault CVT car that was banned from racing for being too good had nearly 800bhp. At one point, Lotus were going to put a CVT in their first V8 road car in the 80s, though that probably wasn't particularly powerful by modern standards.
