It's the technology used in Formula One, although if regulations didn't prohibit it, the DCT would likely have taken its place, just as sequentials had replaced manuals. The trouble with sequential transmissions is that they're jerky, burn through clutches and generally don't work as well as the newer DCTs (though they are lighter). That weight concern is what kept Jaguar
from using a DCT on its upcoming C-X75 supercar, but nearly all of its rivals are switching to two clutches. Ferrari has embraced DCTs (despite earlier reservations). Arch-rival McLaren
went even further with its pre-cog system. Bugatti
uses a DCT, and now Audi
has put a DCT in its R8 supercar.
