I didn't think you could get auto anymore on the 135i. It's manual or DCT only?
Lotus, you forget that BMW starts building the X3 30D this month using the exact same transmission, with 560nm/413 lb/ft.
As for Porsche, they were the inventors of dual clutch gear box (not sure in conjunction with which transmission specialist) for their 962 race car. It was absolutely brutal though and it took 20 years for electronics to catch up for it to be possible to use for road cars.
