Of course Magna Steyr is the Foxconn of cars. The curious question is why didn't Apple go to them?
Actually it is just Magna. Magna Steyr makes some of the most interesting ones but all of Magna has done contract vehicle assembly since the 1970's. Unlike many Tier Ones they have devoted serious resources to BEV, and have Ford Focus Electric, a couple BMW's, Jaguar I-Pace and others to show, but they always have been Tier One plus a bit.

Their ICON system might not be too easily dismissed:

As for vehicles they have designed and built or just built the Wiki has a partial list:

FWIW, I have owned six cars built my Magna-Steyr, three of which were not in the Wiki list.
From their first EV in 2008 to several built in China today, including a couple with BAIC, Magna has devoted major attention to BEV's. Nobody anywhere brags about that, including ones like Daimler and BMW who try to minimize their role.
Tesla is a client of Magna and will probably end out with more Magna-Steyr and Magna China cooperation. Since Tesla is now prepared to allow some of their proprietary techniques by third parties I'll wager a substantial amount that the Tesla/Magna relationship will grow. There are others, after all Magna is only the third-largest industry suppliers. But Magna is the largest contract manufacturer by a significant margin.
Magna is ideally placed to distribute Tesla technologies without the political baggage of Tesla itself doing that. Magna has made it's entire history on allowing their clients to pretend they are doing it themselves. For years deflation of origin in Austria was a big hint. Now they might make more vehicles in China than in Austria. With annual production of ~4 million they are larger than several of their best clients.
Disclosure: I have been a Magna shareholder from time to time since 1990.
