During a ride-and-drive press event, Jim Frederico, chief engineer for Buick, told journalists that the Buick Regal would get a manual transmission as an optional extra.
This transmission is presumably the same one as in the Opel/Vauxhall Insignia, a six-speed. The optional extra will be added shortly after the launch of the car.
I think this is brilliant news. There hasn’t been a manual Buick in ages, and the Regal seems like a fitting car to finally revive the manual with. Hopefully the range-topper under consideration will receive the manual option as well (Providing that it makes it into production in the first place).
