The high body mounting point for spring/shock loads is quite compatible with unibody structural design, so I doubt they'll change it for car models. The pickup truck, though, will likely have a different structure, with different spring/shock mounting... but it's all speculation at this point.IMO, the Tesla strut suspension sucks. As Brian points out, the load point is way high. It'll be interesting to see if and how they ditch this with Roadster II, and even the pickup truck (if it actually is a truck vs an electrified Honda Ridgeline).
Damien couldn't make the Tesla drive unit work with the BMW 850 suspension, so he ripped it out and downgraded to an older BMW semi-trailing arm suspension... the only type that typically fits easily with the Tesla drive unit; the tendency for Tesla-powered conversions to be older Porsches and BMWs is not just by coincidence. The K1 Attack suspension (presumably from the front of an old Accord, but they also offer an MR2 version which uses the donor's rear McPherson struts) is not semi-trailing arm, is designed specifically to work with a transverse engine ahead of the axle line, and will not easily work with the Tesla drive unit.Why have the Tesla subframe at all -- seems to me like it's a lot easier to just mount the drive unit itself (IIRC Damian, a <gasp> Youtuber, did that with his BMW), and run your axles to something with a more sane and/or conventional geometry?
The Tesla Model S/X rear suspension geometry is entirely sane and quite conventional. It is not a McPherson strut; it is a multilink design, of the "integral link" type also used by Ford and Jaguar. The spring/shock unit's lower end mounts directly to the hub carrier, providing a desirable 1:1 motion ratio, but it connects though only a single bushing so it does not control the suspension geometry at all (unlike a McPherson strut with its rigid lower mounting to the hub carrier, so it controls caster and camber). Both the 1:1 motion ratio (at the rear) and the mounting of springs and shocks to the body rather than the subframe (at both ends) are characteristics shared with the current Mazda MX-5 (Miata). Edmumds has a good "walkaround" tour of the Tesla suspension.
