The revolutionary monocoque transverse engined front wheel drive 1959 Austin Mini, that set the template for modern front wheel drive cars, used front and rear subframes to provide accurate road wheel control while using a stiff lightweight body.
At the DS3 signal level, the intermediate element receiving an errored signal replaces the errored channel data with a signal consisting of a valid DS-3 frame with the overhead bits (the M-subframe alignments bits, M-frame alignment bits, and P bits) with the payload set to a 1010..
The subframe housed BRM's type 56 engine, a 1.5 liter V8 and a Colotti gearbox.
